Causal mediation analysis is complicated with multiple effect definitions that require different sets of assumptions for identification. This article provides a systematic explanation of such assumptions. We define five potential outcome types whose means are involved in various effect definitions. We tackle their mean/distribution’s identification, starting with the one that requires the weakest assumptions and gradually building up to the one that requires the strongest assumptions. This presentation shows clearly why an assumption is required for one estimand and (...) not another, and provides a succinct table from which an applied researcher could pick out the assumptions required for identifying the causal effects they target. Using a running example, the article illustrates the assembling and consideration of identifying assumptions for a range of causal contrasts. For several that are commonly encountered in the literature, this exercise clarifies that identification requires weaker assumptions than those often stated in the literature. This attention to the details also draws attention to the differences in the positivity assumption for different estimands, with practical implications. Clarity on the identifying assumptions of these various estimands will help researchers conduct appropriate mediation analyses and interpret the results with appropriate caution given the plausibility of the assumptions.

In many disciplines, mediating processes are usually investigated with randomized experiments and linear regression to determine if the treatment affects the outcome through a mediator. However, randomizing the treatment will not yield accurate causal direct and indirect estimates unless certain assumptions are satisfied since the mediator status is not randomized. This study describes methods to estimate causal direct and indirect effects and reports the results of a large Monte Carlo simulation study on the performance of the ordinary regression (...) and modern causal mediation analysis methods, including a previously untested doubly robust sequential g-estimation method, when there are confounders of the mediator-to-outcome relation. Results show that failing to measure and incorporate potential post-treatment confounders in a mediation model leads to biased estimates, regardless of the analysis method used. Results emphasize the importance of measuring potential confounding variables and conducting sensitivity analysis. (shrink)

Estimating the effect of a randomized treatment and the effect that is transmitted through a mediator is often complicated by treatment noncompliance. In literature, an instrumental variable (IV)-based method has been developed to study causal mediation effects in the presence of treatment noncompliance. Existing studies based on the IV-based method focus on identifying the mediated portion of the intention-to-treat effect, which relies on several identification assumptions. However, little attention has been given to assessing the sensitivity of the identification (...) assumptions or mitigating the impact of violating these assumptions. This study proposes a two-stage joint modeling method for conducting causal mediation analysis in the presence of treatment noncompliance, in which modeling assumptions can be employed to decrease the sensitivity to violation of some identification assumptions. The use of a joint modeling method is also conducive to conducting sensitivity analyses to the violation of identification assumptions. We demonstrate our approach using the Jobs II data, in which the effect of job training on job seekers’ mental health is examined. (shrink)

How do humans discover causal relations when the effect is not immediately observable? Previous experiments have uniformly demonstrated detrimental effects of outcome delays on causal induction. These findings seem to conflict with everyday causal cognition, where humans can apparently identify long-term causal relations with relative ease. Three experiments investigated whether the influence of delay on adult human causal judgements is mediated by experimentally induced assumptions about the timeframe of the causal relation in question, as (...) suggested by Einhorn and Hogarth (1986). Causal judgements generally decreased when a delay separated cause and effect. This decrease was less pronounced when the thematic context of the causal relation induced participants to expect a delay. Experiment 3 ruled out an alternative explanation of the effect based on variations of cue and outcome saliencies, and showed that detrimental effects of delay are reduced even more when instructions explicitly mentioned the timeframe of the causal relation in question. Knowledge thus mediates the impact of delay on human causal judgement. Implications for contemporary theories of human causal induction are discussed. (shrink)

Current literature on resistance focuses on the elements of action and opposition as its main components. However, when we use the term resistance we are not necessarily referring exclusively to the active expression of opposition, but could also be referring to discussions about such events or to stimuli that may cause these acts. Thus resistance, for the purposes of this study, is perceived in terms of action, external conversation and stimuli, and it is argued that these external characteristics may be (...) further processed through deliberation and internal conversations about resistance. An exploratory empirical study revealed inner aspects of resistance, and examined whether internal conversations about resistance could actually be experienced by agents. This article further supports the argument that, as individuals produce internal conversations about resistance, they may end by following one of the suggested options: they may keep their internal conversations unspoken, or produce a course of action related to resistance (and identified as such), or they may produce external conversations about resistance, or they may end by producing resistance that is not recognisable (to others) as such. In all these cases, internal conversations about resistance are involved and it is therefore argued that the causal impact of resistance may derive from agential processes and powers as well as from action, stimuli or external conversations related to resistance.

Technological mediation theorists (such as Don Ihde and Verbeek) believe that human beings’ moral actions can be transformed through technological artefacts to constitute a “good life”. This paper, however, critically analyses two understandings of technological mediation, (1) technological mediation is something between humans and the world (prominent in Don Ihde), and (2) technological mediation is a direct constitutive effect (prominent in Verbeek), which will inevitably lead to the problem of “moral suspension” that I define. In the (...) first understanding (following Zygmunt Bauman), the causal relations between moral actions and actual consequences are distanced from each other because of the “interval” effects of technological artefacts. In the second understanding (following Jean Baudrillard), designers are just “simulating” moralities in specific use and design contexts. Thus, moral realities are ultimately replaced by moral “simulacra”. Then, I argue that to overcome the problem of “moral suspension,” rather than distancing actions from their consequences or simulating moralities in specific scenarios, two possible approaches may be needed, the Way of Zhuangzi who declined to use any adroit technology to improve efficiency, thereby clarifying the relationship between moral actions and consequences; and the attitude of Bauman, who motivated our moral consciences and moral sensitivities, thereby reflecting the side effects of technological mediations and systems. In the end, I conclude that both of these two approaches are too difficult to universally apply, and the most viable approach is to use what Confucius called “the Doctrine of the Mean,” i.e., seeking a balance between the two approaches. That is, while we should acknowledge that technologies intervene our lifeworld and constitute our thinking and moralizing ways, we also need to break away from technological trivialities to think about and pursue long-term moral goals.

Questions concerning mediated causal effects are of great interest in psychology, cognitive science, medicine, social science, public health, and many other disciplines. For instance, about 60% of recent papers published in leading journals in social psychology contain at least one mediation test (Rucker, Preacher, Tormala, & Petty, 2011). Standard parametric approaches to mediation analysis employ regression models, and either the “difference method” (Judd & Kenny, 1981), more common in epidemiology, or the “product method” (Baron & Kenny, 1986), (...) more common in the social sciences. In this article, we first discuss a known, but perhaps often unappreciated, fact that these parametric approaches are a special case of a general counterfactual framework for reasoning about causality first described by Neyman (1923) and Rubin (1924) and linked to causal graphical models by Robins (1986) and Pearl (2006). We then show a number of advantages of this framework. First, it makes the strong assumptions underlying mediation analysis explicit. Second, it avoids a number of problems present in the product and difference methods, such as biased estimates of effects in certain cases. Finally, we show the generality of this framework by proving a novel result which allows mediation analysis to be applied to longitudinal settings with unobserved confounders. (shrink)

This study aimed to investigate the effect of perfectionistic concerns on mobile phone addiction and the mediating role of academic procrastination, as well as the moderating role of causality orientations. A cross-sectional sample of 625 Chinese college students completed measures of PC, AP, causality orientations, and MPA. We analyzed the survey data using structural equation modeling in Mplus 8.0. PC was positively related to MPA. In addition, AP partially mediated this association. The hypothesized moderating effect of autonomous orientation and controlled (...) orientation was not supported. Impersonal orientation moderated the second stage of the mediating effect of AP on the PC–MPA link in that the mediating effect was positive when impersonal orientation was high, while the mediating effect was not significant when impersonal orientation was low. The findings confirm the importance of investigating how individual difference contributes to MPA. The implications of the findings for relieving MPA or preventing college students from developing MPA are also discussed deeply and thoroughly. (shrink)

An influential philosophical conception of our mind’s place in the world is as a site for the states and events that causally mediate the world we perceive and the world we affect. According to this conception, states and events in the world cause mental states and events in us through the process of perception. These mental states and events then go on to produce new states and events in the world through the process of action. Our role is as hosts (...) for these states and events that causally mediate the states and events on the input side and those on the output side. (shrink)

Robots that can communicate with people are one of the goals reached by the technology developed for automation in work life. Experts aim to improve the communication skills of these robots further in the near future. Besides, various studies emphasize that people may interact with robots in a similar way as they interact with other people. In line of this idea, this study examines the possible causal chain in which the social anxiety affects the robot anxiety which in turn (...) affects the attitude toward interacting with robots. Data obtained from university students were analyzed in a simple and parallel mediation model. The results showed that robot anxiety and in particular two of its sub-dimensions mediate the relationship between social anxiety and negative attitudes toward interaction with robots. Researchers should carry out new studies about the common structural characteristics of the anxiety felt by people due to interacting with humans and robots. (shrink)

Rolls demonstrates how reward/punishment systems are key mediators of cognitive appraisal, and this suggests a fundamental, causal role for emotion in thought and behaviour. However, this causal role for emotion seems to drop out of Rolls's model of consciousness, to be replaced by the old idea that emotion is essentially epiphenomenal. We suggest a modification to Rolls's model in which cognition and emotion activate each other reciprocally, both in appraisal and consciousness, thus allowing emotion to maintain its (...) class='Hi'>causal status where it matters most.

An extended definition of “observation” is developed in order to account for the usage in the physical sciences and in neuropsychology. An observation is initially defined as a perception that has a focus of attention and is guided by theoretical considerations. Since the focus may change, one adopts a pluralist position according to which the object of perception may involve any stage of the causal chain that leads to perception, such as the source of light or sound, the obstructions, (...) the medium or even the receptor. The “neutral” observations of the empiricists are seen as involving only low-level or medium-level theorization. Examples are examined, such as a lunar eclipse, the rainbow, and observations mediated by instruments, whose “artifacts” are considered observations of the instrument itself. One also defines null-effect observations. Observations of photographs and drawings may be considered either the observation of a printed sheet of paper or the observation of the pictured object or people. This causal-pluralist metatheory of observation also accepts that one may “observe light”, observe the retina, and observe parts of the brain which are outside the region of the “sensorium”. Illusions and hallucinations are analyzed within this “observational materialism”, which considers that qualia are self-observations of the brain. Criticisms that the approach is too wide in scope are analyzed in the conclusion. (shrink)

The The sustainability of social life is based on social values. The manifestation of these values also takes place within the society. On the other hand, the realization of individuals is possible in society because a non-social human being is not a "human" in the philosophical sense. With human-oriented conditions that manifest themselves in the network of social relations, the criteria (moral values) related to the purpose of creation crystallize and become known so that the construction of a social paradigm (...) becomes possible. However, the society in which individuals live is also surrounded by an external world (material world). For this reason, the social paradigm also indirectly relies on a perception of the outside world. Thus, no matter what period of history, people's endeavor for an ideal society is accompanied by an interpretation of the external world, and with this "cumulative" knowledge, a "reducing" simulation of being is derived (cosmology). In fact, causality, which is the subject of physics, becomes the subject of philosophy in this mediation. As it can be understood, a significant problem here is the correlation between the fixed values (unconditional imperatives) that form the core of the social paradigm and the variable external world knowledge that is culturally effective in the manifestation of these values. Consequently, while determining the rules in the social order, one should act on the basis of values, not as if they have absolute knowledge of the material world. Whether we believe that the universe consists of "seven heavens" and is geocentric or heliocentric; Existential values such as justice, equality, and freedom are essential regardless of time and space. However, as historical facts show, those who have problems with this value system, which is accompanied by an interpretation of the external world, have raised objections through ever-developing knowledge of nature instead of universal values. For this reason, the geocentric perception of the universe, which forms the basis of the political paradigm in the class-based society of medieval Europe, was strongly desired to be maintained by the ruling classes. Ultimately, although this model of the universe collapsed, moral pursuits of human life continued to be sabotaged for the same political reasons, and disinformation began. Thus, scientific studies and the search for the truth (philosophy) were accompanied by endless polemics disguised as "philosophy." In fact, this situation reveals two opposing attitudes that repeat themselves in history, either in the East or the West: paradigmatic attitude (paradigmism) and enigmatic attitude (enigmatism). As a reflection of these two attitudes, the dominant discourse, which categorically accuses even the interest in understanding Western modernization in the Islamic world as heresy, did not occasionally hesitate to refer to some Western references by confirming with a vulgar pragmatism. For instance, Newtonian physics has been ignored. On the other hand, an attempt has been made to jump directly from Aristotelian physics to quantum physics by assuming an overlapping in classical texts. However, facing the new knowledge of nature has more actual consequences than polemics. To face these results and to show the legitimacy of Islamic values in the modern era, which are in conformity with the creation of human beings, the developments in the current knowledge of the universe (modern cosmology) cannot be ignored. This endeavor can be possible only when the philosophical and historical foundations of the subject are examined throughout the Western experience. (shrink)

Two variables are usually recognised as determinants of human causal learning: the contingency between a candidate cause and effect, and the temporal and/or spatial contiguity between them. A common finding is that reductions in temporal contiguity produce concomitant decrements in causal judgement. This finding had previously (Shanks & Dickinson, 1987) been interpreted as evidence that causal induction is based on associative learning processes. Buehner and May (2002, 2003, 2004) have challenged this notion by demonstrating that the impact (...) of temporal delay depends on expectations about the timeframe between cause and effect. A corollary of this knowledge-mediation account is that in certain situations longer delays could facilitate, while shorter delays should impair, causal learning. Here we present two experiments involving a physical apparatus that demonstrate a detrimental effect of contiguity under certain conditions. In contrast to all previous studies, delays universally promoted causal learning. This evidence is clearly at variance with the notion of a bottom-up contiguity bias in causal induction. A new, more general timeframe bias is discussed. (shrink)

An alleged counterexample to causal decision theory, put forward by Andy Egan, is studied in some detail. It is argued that Egan rejects the evaluation of causal decision theory on the basis of a description of the decision situation that is different from—indeed inconsistent with—the description on which causal decision theory makes its evaluation. So the example is not a counterexample to causal decision theory. Nevertheless, the example shows that causal decision theory can recommend unratifiable (...) acts which presents a problem in the dynamics of intentions. It is argued that we can defuse this problem if we hold that decision theory is a theory of rational decision making rather than a theory of rational acts. It is shown how decisions can have epistemic side-effects that are not mediated by the act and that there are cases where one can only bring oneself to perform the best act by updating by imaging rather than by conditioning. This provides a pragmatic argument for updating by imaging rather than by conditioning in these cases. (shrink)

Collingwood's faith in the historian's intuitive capacity for discerning the meaning of past actions by re-enactment" is too unqualified. However, his thesis that through actions alone can reasons and inner meanings be discovered is true. This assumes that actions can be traced to recognizable agents and that these agents are able to acknowledge their reasons. The relation between knowing and doing and between knowing and understanding is a form of causality not inconsistent with teleological reasoning. Characteristic of human action are (...) the constitutive nature of causality, the delimiting effect of rationality on human autonomy, and the role of purpose as a mediating link between intention and outcome. Despite the fact that emphasis on impersonal actions and interactions seriously calls into question Collingwood's theory of understanding, any radical revision of this theory proves no less problematical.

In defending the scientific legitimacy of ceteris paribus qualified causal generalizations, we situate and specify the reference of the ceteris paribus proviso within a fundamental causal framework consisting of causal agents, pathways of influence, mediators, moderators, and causal consequences. In so doing, we provide an explication of the reference and utility of the ceteris paribus proviso in terms of mediators and moderators as these constitute the range of factors that can impinge on the relation between cause (...) and effect. We argue that the conceptual causal roadmap embodied by the ceteris paribus qualification serves as a schematic template for the ongoing identification of causally relevant factors and plays an indispensable heuristic role in advancing scientific inquiry into causal relations. We then provide guidelines for differentiating between acceptable and unacceptable uses of ceteris paribus and describe how mediators and moderators conceptually encompassed by the ceteris paribus proviso can be employed in evaluating the meaning and acceptability of proposed ceteris paribus causal generalizations, as well serve as a guide to investigators in the process of designing studies to identify a causal agent, mediators, moderators, pathways of influence, and causal consequences. 2012 APA, all rights reserved).

Kalisch et al. discuss the causal process underlying stress in terms of a multidimensional goal-appraisal process, but there are several mechanisms at various levels of the brain that use different types of information to guide behavior. Depending on the mechanism, the characteristics of the process are different. Hence, both research and prevention must deal with appraisal in mechanism-specific ways.

SummaryIn the 1780s the anatomist Vincenzo Malacarne discussed the possibility of testing experimentally whether experience can induce significant changes in the brain. Malacarne imagined taking two littermate animals and giving intensive training to one while the other received none, then dissecting their brains to see whether the trained animal had more folds in the cerebellum than the untrained one. This experimental design somewhat anticipated one used 180 years later by Mark R. Rosenzweig at the University of California, Berkeley. This paper (...) explores some methodological aspects of the case study just outlined by pointing out that our grounds for being interested in it are neither merely neuroscientific (for, strictly speaking, Malacarne's proposal was false) nor narrowly historical (for there is no causal chain linking Malacarne's ideas to Rosenzweig's experiment). Rather, the really interesting point here is to what extent Malacarne's ideas are similar to Rosenzweig's, a point that we can better investigate by employing certain conceptual tools borrowed typically (but not exclusively) from (a certain kind of) philosophy. If we do not handle the analogy with care, we run the risk of ‘discovering’ nothing but void platitudes or anachronistically misleading common features. (shrink)

Although maxims are central to Kant’s ethical theory, his account of them remains obscure. We can make progress towards understanding Kantian maxims by examining not only their role as the object of moral judgement but also their connection to freedom of the will and causality. This requires understanding maxims as causal laws that explain the actions that we impute to agents. In this way, they are analogous to causal laws of nature, but they are limited in scope to (...) the agents who are responsible for them. Understanding maxims in this way explains our limited epistemic access to them and helps to clarify Kant’s account of virtue and character as well as how they mediate the relationship between practical and theoretical reason.

Purpose - The aim of this research was to investigate the effect of transformational leadership and transactional contingent reward as complementary, but distinct, forms of leadership on facets of organizational identification via the perception of innovation and goal organizational values. Design/methodology/approach – Three studies were carried out implementing either a measurement of mediation or experimental-causal-chain design to test for the hypothesized effects. Findings - The measurement of mediation study showed that transformational leadership had a positive direct and (...) indirect effect, via innovation value orientation, on cognitive identification, whereas transactional contingent reward was more strongly related to affective, rather than cognitive, identification, and goal orientation was a mediator of their link. The findings of the two experimental-causal-chain studies further supported the hypothesized effects. Transformational leadership was found to lead subordinates to perceive the culture as more innovative compared to transactional contingent reward, whereas transactional contingent reward led employees to perceive the culture as more goal, than innovation, oriented. Finally, innovation, compared to goal, value orientation increased cognitive identification, while goal orientation facilitated affective, rather than cognitive, identification. Implications - The practical implications involve the development of strategies organizations can apply, such as leadership training programs, to strengthen their ties with their employees, which, in turn, may have a positive impact on in-role, as well as extra-role, behaviors. Originality/Value – The originality of this research concerns the identification of distinct mechanisms explaining the effect of transformational leadership and transactional contingent reward on cognitive and affective identification applying an organizational culture perspective and a combination of measurement and causal mediation designs.

In lieu of an abstract, here is a brief excerpt of the content:Wittgenstein on Non-Mediative CausalityJames C. KlaggeIn the late autumn of 1947 Wittgenstein dictated a selection of manuscript material to a typist1 that contains some remarks so striking that they merit extensive quotation:903. No supposition seems to me more natural than that there is no process in the brain correlated with associating or with thinking; so that it would be impossible to read off thought-processes from brain-processes. I mean this: (...) if I talk or write there is, I assume, a system of impulses going out from my brain and correlated with my spoken or written thoughts. But why should the system continue further in the direction of the centre? Why should this order not proceed, so to speak, out of chaos? The case would be like the following—certain kinds of plants multiply by seed, so that a seed always produces a plant of the same kind as that from which it was produced—but nothing in the seed corresponds to the plant which comes from it; so that it is impossible to infer the properties or structure of the plant from those of the seed that it comes out of—this can only be done from the history of the seed. So an organism might come into being even out of something quite amorphous, as it were causelessly; and there is no reason why this should not really hold for our thoughts, and hence for our talking and writing. (Zettel 608)904. It is thus perfectly possible that certain psychological phenomena cannot be investigated physiologically, because physiologically nothing corresponds to them. (Z 609)905. I saw this man years ago; now I have seen him again, I recognize him, I remember his name. And why does there have to be a cause of this remembering in my nervous system? Why must something or other, whatever it may be, be stored-up there in any form? Why must a trace have been left behind? Why should there not be a psychological regularity to which no physiological regularity corresponds? If this upsets our concepts of causality, then it is high time they were upset. (Z 610) [End Page 653]906. The prejudice in favor of psycho-physical parallelism is also a fruit of the primitive conception of grammar. For when one admits a causality between psychological phenomena, which is not mediated physiologically, one fancies that in doing so one is making an admission of the existence of a soul alongside the body, a ghostly soul-nature. (cf. Z 611)909. Why should not the initial and terminal states of a system be connected by a natural law, which does not cover the intermediary state? (Only don’t think of efficacy/influence [Wirkung]!) (Z 613)918. …Well—but now that the structure of the eye is known—how does it come about that we act, react, in this way? But must there be a physiological explanation here? Why don’t we just leave explaining alone?—But you would never talk like that, if you were examining the behavior of a machine!—Well, who says that a living creature, an animal body, is a machine in this sense?— (Z 614)Lest you think, or hope, these ideas were just a passing fancy of Wittgenstein’s, it is worth noting that these passages were among the ones that he cut from this typescript to save in a box and rearrange and perhaps revise for future use. They were published posthumously as Zettel.2What are we to make of these striking ideas? Do they hint at “mystical vitalism”? Is there an intellectual trajectory along which they can be located and appreciated, even if perhaps ultimately rejected? Or is he simply making a “natural” objection to reductionism about memory?3In an earlier publication I briefly offered a motivation for these views,4 but I now have more to say and wish to try again. Earlier I saw these passages primarily in relation to Wittgenstein’s other views about mental phenomena, but I now think something can be gained by seeing them in relation to his views about causality. Unfortunately causality is not a topic about which Wittgenstein had... (shrink)

Mediation analysis has been used in many disciplines to explain the mechanism or process that underlies an observed relationship between an exposure variable and an outcome variable via the inclusion of mediators. Decompositions of the total effect of an exposure variable into effects characterizing mediation pathways and interactions have gained an increasing amount of interest in the last decade. In this work, we develop decompositions for scenarios where two mediators are causally sequential or non-sequential. Current developments in this (...) area have primarily focused on either decompositions without interaction components or with interactions but assuming no causally sequential order between the mediators. We propose a new concept called natural mediated interaction effect that captures the two-way and three-way interactions for both scenarios and extends the two-way MIs in the literature. We develop a unified approach for decomposing the TE into the effects that are due to mediation only, interaction only, both mediation and interaction, neither mediation nor interaction within the counterfactual framework. Finally, we compare our proposed decomposition to an existing method in a non-sequential two-mediator scenario using simulated data, and illustrate the proposed decomposition for a sequential two-mediator scenario using a real data analysis.

There are hints that the connectivity of space-time in quantum gravity could emerge from entanglement, and it has further been proposed that any two entangled particles may be connected by a quantum wormhole. One way to test this proposal is by probing the electric field of an entangled charged particle to determine whether its electric field leaks through the putative wormhole. In addition, if such a wormhole is traversable, then it could be possible for the collapse of the wave function (...) to occur in a causal manner, with information about the collapse travelling through the wormhole at the speed of light, rather than the wave function collapse being a global and instantaneous event.

PurposeSelf-efficacy has been argued theoretically and shown empirically to be an essential construct for students’ improved learning outcomes. However, there is a dearth of studies on its causal effects on performance in mathematics among university students. Meanwhile, it will be erroneous to assume that results from other fields of studies generalize to mathematics learning due to the task-specificity of the construct. As such, attempts are made in the present study to provide evidence for a causal relationship between self-efficacy (...) and performance with a focus on engineering students following a mathematics course at a Norwegian university.MethodThe adopted research design in the present study is a survey type in which collected data from first-year university students are analyzed using structural equation modeling with weighted least square mean and variance adjusted estimator. Data were generated using mainly questionnaires, a test of prior mathematics knowledge, and the students’ final examination scores in the course. The causal effect of self-efficacy was discerned from disturbance effects on performance by using an innovative instrumental variable approach to structural equation modeling.ResultsThe findings confirmed a significant direct effect of the prior mathematics knowledge test on self-efficacy, a significant direct effect of self-efficacy on performance, and a substantial mediating effect of self-efficacy between a prior mathematics knowledge test and performance. Prior mathematics knowledge and self-efficacy explained 30% variance of the performance. These findings are interpreted to be substantial evidence for the causal effect of self-efficacy on students’ performance in an introductory mathematics course.ConclusionThe findings of the present study provide empirically supports for designing self-efficacy interventions as proxies to improve students’ performance in university mathematics. Further, the findings of the present study confirm some postulates of Bandura’s agentic social cognitive theory. (shrink)

I argue for an inferentialist account of the meaning of causal claims, which draws on the writings of Sellars and Brandom. The account is meant to be widely applicable. In this work, it is motivated and defended with reference to complex systems sciences, i.e., sciences that study the behaviour of systems with many components interacting at various levels of organisation (e.g. cells, brain, social groups). Here are three, seemingly-uncontroversial platitudes about causality. (1) Causal relations are objective, mind-independent relations (...) and, as such, analysable in objective, mind-independent terms. (2) There is a tight connection between our practice of predicting, explaining and controlling phenomena, and the use of causal notions. (3) The second platitude should be explained in terms of the first. Contrary to this widely-held stance, I suggest that we reverse the order of analysis, by taking our activities of agents as the raw material in terms of which to account for the obtaining of causal relations. To this end, I propose and defend an inferentialist account of causality. Causality is a ‘category’ that the knowing subject employs to ‘mediate’ between himself and the world. In inferentialist terms, this mediation is the result of the concept of cause figuring in a network of inferences, used in our practice of gathering evidence and using it to explain, predict and intervene. Complexity only makes the mediation more difficult, thereby rendering the meaning of causality more evident. (shrink)

In an increasingly complex external environment, innovation is an important way for companies to build sustainable competitiveness. This research discusses employee creativity from the perspective of Family Supportive Supervisor Behavior based on conservation of resource theory, social exchange theory, psychological capital theory and emotional spillover theory. Through a series of surveys of employees in different companies and jobs, we can understand the impact of family-supporting supervisors’ behavior on their creativity. Combined with the survey data, a structural equation model is constructed (...) to analyze the mediating effects of psychological capital and positive emotions based on the causal mediation model. The research found that the positive influence of family-supporting supervisors’ behavior on employees’ creativity has three forms. First, supervisors improve employees’ motivation and sense of efficacy by providing various support resources. Second, supervisors can generate positive spillover effects among employees by influencing employees’ psychological state. Third, supervisors stimulate the creativity of subordinates by promoting work participation and mobility. According to the research conclusions, in order to improve the employee creativity, we should provide incentives to encourage supervisors to carry out family support behaviors, identify employee characteristics to help supervisors provide personalized support, cultivate family supportive leaders, and attach importance to emotional support and play the role of psychological capital and positive emotions.

The demand for ethical fashion products has grown in recent years, with consumers caring more about how the product is made. Based on the deontological underpinnings of ethical fashion, the present research provides recommendations to ethical fashion brands by leveraging the emotion of awe through visual representations. This research examines 5362 Instagram posts of five ethical fashion brands and shows that the presence of awe-inspiring visual elements increases consumer engagement on social media for ethical fashion brands. Further, this research identifies (...) the moderating roles of the color green and the size of the visual elements in this context. Two follow-up experiments provide causal evidence for these relationships. Experimental evidence for the role of deontological beliefs as a mediator of the relationship between feelings of awe and social media engagement with ethical fashion brands is also provided. Overall, the findings offer a more nuanced understanding of how ethical fashion brands can develop effective visual advertising campaigns on social media and the underlying process driving the effect, which is consistent with deontological ethics.

We investigate the causal manipulability hypothesis, according to which what partly explains (a) why people tend to prefer negative events to be in their further future rather than their nearer future and positive events to be in their nearer future rather than their further future and (b) why people tend to prefer that negative events be located in their past not their future and that positive events be located in their future not their past, is that people tend to (...) discount the value of events they are less able causally to manipulate. If people discount the value of events they are less able to causally manipulate, then since often temporally nearer future events are more causally manipulable than further ones, and since future events are manipulable whereas past ones aren’t, this could explain both (a) and (b). In turn, if the causal manipulability hypothesis is correct, this might suggest that insofar as people’s preferences are explained in this manner, those preferences are rationally permissible, since relative causal manipulability is normatively relevant. Thus, ascertaining whether the causal manipulability hypothesis is true may shed light on the normative status of such preferences. We investigate the cognitively mediated version of the causal manipulability hypothesis, according to which people’s consciously held beliefs about the relative causal manipulability of events explains (a) and (b). Contrary to expectations, we found no evidence in favour of this view. We suggest that either relative causal manipulability plays an explanatory role, but one that is not cognitively mediated, or that it does not play any role, even if it is sometimes associated with other factors, such as probability, that may play a role in explaining some time biased preferences.

This study introduces the concept of deviant behavior in a moderated-mediation framework of incentives and organizational justice perception. The proposed relationships in the theoretical framework were tested with a sample of 311 academics, using simple random sampling, via causal models and structural equation modeling. The findings suggest that incentives might boost the apparent performance, but not necessarily the intended performance. The results confirm that employees’ affection for incentives has direct, indirect, and conditional indirect effects on their deviant behavior (...) likelihood. The relationship between employee deviant behavior likelihood and affection for incentives was moderated by organizational justice perception and partially mediated by reward expectancy, thus having significant contributions toward the extant literature of deviant behavior and incentives. The findings have important implications for managers, academicians, and policy makers for mitigating adverse behavior in professional employees through proper use of incentives. (shrink)

This dissertation begins by addressing the question of when a causal model is apt for deciding questions of actual causation with respect to some target situation. I first provide relevant background about causal models, explain what makes them promising as a tool for analyzing actual causation, and motivate the need for a theory of aptness as part of such an analysis (Chapter 1). I then define what it is for a model on a given interpretation to be accurate (...) of, that is, say only true things about, some target situation. This involves a systematization of various representational principles mentioned and/or discussed throughout the literature into a method of interpretation, which I propose be taken as standard (Chapter 2). Next, I explain and address two reasons for which accuracy as I’ve defined it is insufficient for aptness. The first reason – already discussed in the literature – is the problem of structural isomorphs. In response, I propose the aptness condition of Explicit Partial Mediation (Chapter 3). The second reason – which has yet to be noticed – is the problem of the indeterminacy of accuracy. As I demonstrate, a model is accurate of a target situation only relative to a set of background possibilities – what I call a modal profile. It follows that a model represents a situation only relative to some modal profile or other. I go on to discuss the ramifications of this observation for a theory of actual causation in terms of models. I argue that the relativity be taken at face value and built into our metaphysical account of causation, resulting in a view that I call causal relativism (Chapter 4). I explore one advantage of this view in detail: that the resulting account can defend the principle of strong proportionality against several objections (Chapter 5). Finally, I apply the earlier discussion of aptness to attempts to provide a semantics of counterfactuals in terms of causal models – an interventionist semantics. I show how just as a similarity semantics relies on an opaque notion of similarity, an interventionist semantics relies on an analogous notion of aptness. The challenge of articulating aptness thus undermines the claim that an interventionist semantics avoids representational problems inherent in a similarity semantics (Chapter 6). I close with a recap and suggestions for future research (Chapter 7). -/- . (shrink)

Understanding students’ learned hopelessness and academic self-esteem is important because the sense of controllability and competence perception can predict deficits in achievement-oriented behaviours and achievement performance. A survey was conducted to examine the role of learned hopelessness and academic self-esteem in academic achievement. Structural equation modelling was used to analyse the mediational roles of learned hopelessness and academic self-esteem in the academic achievement of 165 Hong Kong junior secondary students. The findings implied that learned hopelessness and academic self-esteem are distinct (...) constructs which play separate mediational roles between prior academic failure and academic achievement. However, the model comparisons indicated that there was no direct effect of learned hopelessness on academic self-esteem or vice versa. (shrink)

Background Developing a framework that illustrates causal relationships and an in-depth comprehension of contextual elements is essential for steering the development of ethical interventions to enhance nurses’ ethical decision-making. Research aim To examine the relationship between cultural competence, professional nursing values, and moral sensitivities of surgical nurses with a mediation analysis and structural equation model. Research design This study is descriptive and correlational. Participants and research context: This study was conducted with a total of 201 surgical nurses from (...) two university hospitals in Konya, Türkiye. Data were gathered face-to-face between June and October 2023 with the Moral Sensitivity Questionnaire (MSQ), Nurses Professional Values Scale-Revised (NPVS-R), and Nurse Cultural Competence Scale (NCCS). Ethical considerations Ethical approval from Necmettin Erbakan University Ethics Committee was obtained (Number: 2023/419). Results In this study, the mean scores for the surgical nurses were as follows: 89.3 ± 19.33 on the MSQ, 113.1 ± 20.74 on the NPVS-R, and 72.06 ± 18.61 on the NCCS. Nurses’ cultural competence level significantly affected their professional nursing values (β = 0.192; p =.007; R2 = 0.04), and their professional nursing values, in turn, had a significant effect on their moral sensitivities (β = −0.363; p <.001; R2 = 0.16). However, it was determined that the direct effect of nurses’ cultural competence level on their moral sensitivity was not statistically significant. In contrast, the indirect effect of nurses’ cultural competence level on their moral sensitivity, mediated by their professional nursing values was seen to be statistically significant (B = −0.070; p =.008). Conclusions This study showed that there is a significant positive relationship between the professional nursing values and cultural competence levels of surgical nurses and that as professional nursing values increase, their moral sensitivity also rises. Sensitivity with higher professional nursing values. Additionally, it was found that nurses’ professional values served as a mediating factor between their levels of cultural competence and moral sensitivity. Therefore, it is crucial to enhance the cultural competence, professional nursing values, and moral sensitivity of nursing students and registered surgical nurses and to improve their reasoning and decision-making skills in ethical dilemmas.

Differences in socioeconomic status (SES) correlate both with differences in cognitive development and in brain structure. Associations between SES and brain measures such as cortical surface area and cortical thickness mediate differences in cognitive skills such as executive function and language. However, causal accounts that link SES, brain, and behavior are challenging because SES is a multidimensional construct: correlated environmental factors, such as family income and parental education, are only distal markers for proximal causal pathways. Moreover, the (...) class='Hi'>causal accounts themselves must span multiple levels of description, employ a developmental perspective, and integrate genetic effects on individual differences. Nevertheless, causal accounts have the potential to inform policy and guide interventions to reduce gaps in developmental outcomes. In this article, we review the range of empirical data to be integrated in causal accounts of developmental effects on the brain and cognition associated with variation in SES. We take the specific example of language development and evaluate the potential of a multiscale computational model of development, based on an artificial neural network, to support the construction of causal accounts. We show how, with bridging assumptions that link properties of network structure to magnetic resonance imaging (MRI) measures of brain structure, different sets of empirical data on SES effects can be connected. We use the model to contrast two possible causal pathways for environmental influences that are associated with SES: differences in prenatal brain development and differences in postnatal cognitive stimulation. We then use the model to explore the implications of each pathway for the potential to intervene to reduce gaps in developmental outcomes. The model points to the cumulative effects of social disadvantage on multiple pathways as the source of the poorest response to interventions. Overall, we highlight the importance of implemented models to test competing accounts of environmental influences on individual differences. (shrink)

I argue that Berkeley's distinctive idealism/immaterialism can't support his view that objects of sense, immediately or mediately perceived, are causally inert. (The Passivity of Ideas thesis or PI) Neither appeal to ordinary perception, nor traditional arguments, for example, that causal connections are necessary, and we can't perceive such connections, are helpful. More likely it is theological concerns,e.g., how to have second causes if God upholds by continuously creating the world, that's in the background. This puts Berkeley closer to Malebranche (...) than to Hume. -/- As far the what I call the "first strategy;" defending the passivity of ideas by ordinary introspection, I refer to the work of the French psychologist Albert Michotte,(1940) and those now extending his experiments, to show that (1) there is an immediate and quite robust visual impression of causality, (admitted in fact by Berkeley, Malebranche and Hume) and (2) of more importance, the impression isn't due to projecting into nature expectations gained from experienced regularities.

We describe a unification of old and recent ideas for formulating graphical models to explain time series data, including Granger causality, semi-automated search procedures for graphical causal models, modeling of contemporaneous influences in times series, and heuristic generalized additive model corrections to linear models. We illustrate the procedures by finding a structure of exogenous variables and mediating variables among time series of remote geospatial indices of ocean surface temperatures and pressures. The analysis agrees with known exogenous drivers of the (...) indices, not assumed in the analysis. Automated search applied to the residuals after regressing each series on its lags and the lags of its Granger causes yields a graphical model of “comtemporaneous” causal relations identical with the qualitative graphical relations from the time series. A similar analysis produces reasonable results when applied to candidate climate indices obtained by a clustering method from sea surface temperature and sea level pressure data. (shrink)

We propose that the pragmatic factors that mediate everyday deduction, such as alternative and disabling conditions (e.g. Cummins et al., 1991) and additional requirements (Byrne, 1989) exert their effects on specific inferences because of their perceived relevance to more general principles, which we term SuperPs. Support for this proposal was found first in two causal inference experiments, in which it was shown that specific inferences were mediated by factors that are relevant to a more general principle, while the same (...) inferences were unaffected by factors not relevant to the general principle. These results were extended to deontic inferences in two further experiments. Taken together, these findings show that unstated superordinate principles play a significant role in certain types of reasoning. Questions raised by the findings for the main theoretical approaches are discussed. (shrink)

This paper introduces and defends a new principle for when a structural equation model is apt for analyzing actual causation. Any such analysis in terms of these models has two components: a recipe for reading claims of actual causation off an apt model, and an articulation of what makes a model apt. The primary focus in the literature has been on the first component. But the problem of structural isomorphs has made the second especially pressing (Hall Citation2007; Hitchcock Citation2007a). Those (...) with realist sympathies have reason to resist the standard response to this problem, which introduces a normative parameter into the metaphysics (Hall Citation2007; Halpern and Hitchcock Citation2010, Citation2015; Halpern Citation2016a; Menzies Citation2017; Gallow Citation2021). However, the only alternative solution in the literature leaves central questions unanswered (Blanchard and Schaffer Citation2017). I propose an independently motivated aptness requirement, Evident Mediation, that provides the missing details and resolves the structural isomorph problem without need for a normative parameter.

Many systems neuroscientists want to understand neurons in terms of mediation; we want to understand how neurons are involved in the causal chain from stimulus to behavior. Unfortunately, most tools are inappropriate for that while our language takes mediation for granted. Here we discuss the contrast between our conceptual drive toward mediation and the difficulty of obtaining meaningful evidence.

This paper examines the mechanisms that influence team-level performance, which is critical to organizational effectiveness. It investigates psychological safety, a shared belief that the team is safe for interpersonal risk-taking, and a causal model mediated by learning behavior and efficacy. This model hypothesizes that psychological safety and efficacy are related, which have been believed to be the same-dimension constructs. It also explains the process of how learning behavior affects the team’s efficacy. According to a study of 104 field teams (...) in a multinational enterprise in Korea, psychological safety did not affect team effectiveness. However, when mediated by learning behavior and efficacy, a full mediation effect was found. The result supports a well-known metaphor that psychological safety is the engine of performance, not the fuel. It also explains how individuals contribute to group performance under a psychologically safe climate, enhancing team processes. Based on the findings, this paper suggests theoretical and methodological implications for future research to maximize the effectiveness of teams. (shrink)

Purpose Genetic research, via the mainstream media, presents the public with novel, profound findings almost on a daily basis. However, it is not clear how much laypeople understand these presentations and how they integrate such new findings into their knowledge base. Genetic knowledge (GK), existing causal beliefs, and genetic essentialist tendencies (GET) have been implicated in such processes; the current study assesses the relationships between these elements and how brief presentations of media releases of scientific findings about genetics are (...) consumed and affect the readers. -/- Methods An Australian national survey of GK, GET, and existing causal beliefs about health phenomena (heart disease and obesity) was conducted. Participants were also exposed to news headlines that offered genetic and non-genetic partial explanations of the same health phenomena and reported their evaluations of these headlines, as well as the effects of the headlines on their personal understanding of the health phenomena. -/- Results GK was negatively-associated with GET. Whereas GK did not directly predict the evaluation and effects of the genetic headlines, GET did. GK predicted the effects of the headlines indirectly via GET and via GET and existing causal beliefs. -/- Conclusion GET seem to predict unwarranted effects of exposure to news headlines about genetic science, whereas GK seems to indirectly mitigate the same unwarranted effects.

When outer objects are seen, it is through mediation by the epistemologically more immediate items, ‘the visual given’ and ‘the visual mediators’. There is reason for thinking that seeing is the result of a two‐stage causal transaction, the first is the psycho‐physical causation of a sensuous array in body‐relative physical space, the second the psycho‐psycho causing by the latter of a mental process that subjects that array to organizing/interpreting in the forming of the visual experience. ‘The given’ names (...) the psychological product of the first transaction: it is the hypothesized middle term in a hypothesized causal triple. Then since the order/meaning in the content of visual experience is wholly determined by the susceptibility of the perceiving mind, ‘The given’ must single out the sensuous array under its minimum description. Meanwhile ‘the visual mediators’ names a set of perceptual go‐betweens, which are proxy for the object, such as light/surface/colour. Their perception is at once that through which object‐perception occurs, and the form taken by it. Finally, it is proposed that the formation of the internal object of the visual experience takes the following form: the mind constitutes out of the ‘given’ a two‐dimensionally ordered internal object, which in turn explanatorily precedes and causes the acquisition of the more ambitious internal visual objects.

Following the implementation of temporary pop-up bike lanes in Berlin, traffic counts by the city administration show an increased number of cyclists. This present paper aims to understand reasons behind this observation. To this end, we focus on the role of mobility-related descriptive social norms as mediators of this effect. Results from one correlational and two experimental online studies are reported. The correlational study confirms the expected association of mobility-related descriptive social norms and self-reported mobility behavior. Moreover, it demonstrates that, (...) as expected, mobility-related descriptive social norms reliably reflect differences in cities’ objective transport structure and mediate the impact of these infrastructural differences on mobility behavior. Results from two online experiments provide additional causal evidence that participants use the visual cues provided by manipulated photos to form their perceived mobility-related descriptive social norms. Furthermore, the second online experiment provides evidence that the combination of infrastructural cues and observable mobility behavior has the strongest impact on perceived mobility-related descriptive social norms.

The purpose of this cross-sectional study was to examine whether psychosocial working conditions may be a mediator between indoor physical working conditions and the type of vague general health symptoms included in the diagnosis of sick building syndrome (SBS). The study was based on survey data from 1505 British white-collar workers from 20 different organizations. A path analysis revealed that there was a significant direct relation between physical working conditions and vague symptoms and also psychosocial job strain (Effort-Reward Imbalance ratio), (...) which in turn also strongly related to the vague symptoms. The findings thus suggested a mediating role between physical working conditions and symptoms for psychosocial job strain. Due to the cross-sectional study design no conclusions on causality can be drawn. (shrink)
