Recent years have seen a gradual convergence of seemingly distant research fields over a single goal: understanding and replicating biological intelligence in artifacts. This work presents a general overview on the origin, the state-of-the-art, scientific challenges and the future of Biologically Inspired Cognitive Architecture (BICA) research. Our perspective decomposes the field into the four principal semantic components associated with the BICA challenge that together call for an integration of efforts of researchers across disciplines. Areas and directions of study where new (...) integrated efforts will be primarily needed are summarized. (shrink)

Several attempts have been made previously to provide a biological grounding for cognitive architectures by relating their components to the computations of specific brain circuits. Often, the architecture's action selection system is identified with the basal ganglia. However, this identification overlooks one of the most important features of the basal ganglia—the existence of a direct and an indirect pathway that compete against each other. This characteristic has important consequences in decision-making tasks, which are brought to light by Parkinson's disease as (...) well as genetic differences in dopamine receptors. This paper shows that a standard model of action selection in a cognitive architecture cannot replicate any of these findings, details an alternative solution that reconciles action selection in the architecture with the physiology of the basal ganglia, and extends the domain of application of cognitive architectures. The implication of this solution for other architectures and existing models are discussed. (shrink)

The ability to reason and problem‐solve in novel situations, as measured by the Raven's Advanced Progressive Matrices (RAPM), is highly predictive of both cognitive task performance and real‐world outcomes. Here we provide evidence that RAPM performance depends on the ability to reallocate attention in response to self‐generated feedback about progress. We propose that such an ability is underpinned by the basal ganglia nuclei, which are critically tied to both reward processing and cognitive control. This hypothesis was implemented in a neurocomputational (...) model of the RAPM task, which was used to derive novel predictions at the behavioral and neural levels. These predictions were then verified in one neuroimaging and two behavioral experiments. Furthermore, an effective connectivity analysis of the neuroimaging data confirmed a role for the basal ganglia in modulating attention. Taken together, these results suggest that individual differences in a neural circuit related to reward processing underpin human fluid reasoning abilities. (shrink)

Going from cognitive theory to neural data to ACT‐R models, the authors relate brain activity in a lexical ambiguity priming task to brain processes that resolve ambiguity in word meanings. These detailed data were tested and found compatible to the results of an ACT‐R computational model of reinforcement learning (RL). The model confirms and extends the behavioral findings to provide a RL account of individual differences in lexical ambiguity resolution.

The Role of Dorsal Premotor Cortex in Resolving Abstract Motor Rules provides alternative hypotheses about the cognitive functions affected by the application of repetitive transcranial magnetic stimulation. Their model simulated the effect of stimulation of the left dorsal premotor cortex right as participants provide a Models were used to demonstrate that the increased variability in observed response times can result from interference in replanning during the process of responding to the uninstructed stimulus.

This paper presents a neurocomputational model using the ACT‐R cognitive architecture that simulates intrusive memory retrieval following a potentially traumatic event and predicts hippocampal volume changes observed in Post‐Traumatic Stress Disorder.

Cognitive architectures (i.e., theorized blueprints on the structure of the mind) can be used to make predictions about the effect of multiregion brain activity on the systems level. Recent work has connected one high-level cognitive architecture, known as the “Common Model of Cognition,” to task-based functional MRI data with great success. That approach, however, was limited in that it was intrinsically top-down, and could thus only be compared with alternate architectures that the experimenter could contrive. In this paper, we propose (...) a bottom-up method to infer a cognitive architecture directly from brain imaging data itself, overcoming this limitation. Specifically, Granger causality modeling was applied to the same task-based fMRI data to infer a network of causal connections between brain regions based on their functional connectivity. The resulting network shares many connections with those proposed by the Common Model of Cognition but also suggests important additions likely related to the role of episodic memory. This combined top-down and bottom-up modeling approach can be used to help formalize the computational instantiation of cognitive architectures and further refine a comprehensive theory of cognition.

Complex skill learning depends on the joint contribution of multiple interacting systems: working memory (WM), declarative long-term memory (LTM) and reinforcement learning (RL). The present study aims to understand individual differences in the relative contributions of these systems during learning. We built four idiographic, ACT-R models of performance on the stimulus-response learning, Reinforcement Learning Working Memory task. The task consisted of short 3-image, and long 6-image, feedback-based learning blocks. A no-feedback test phase was administered after learning, with an interfering task (...) inserted between learning and test. Our four models included two single-mechanism RL and LTM models, and two integrated RL-LTM models: (a) RL-based meta-learning, which selects RL or LTM to learn based on recent success, and (b) a parameterized RL-LTM selection model at fixed proportions independent of learning success. Each model was the best fit for some proportion of our learners (LTM: 68.7%, RL: 4.8%, Meta-RL: 13.25%, bias-RL:13.25% of participants), suggesting fundamental differences in the way individuals deploy basic learning mechanisms, even for a simple stimulus-response task. Finally, long-term declarative memory seems to be the preferred learning strategy for this task regardless of block length (3- vs 6-image blocks), as determined by the large number of subjects whose learning characteristics were best captured by the LTM only model, and a preference for LTM over RL in both of our integrated-models, owing to the strength of our idiographic approach.

Transcranial magnetic stimulation (TMS) of the visual cortex can induce phosphenes as can non-diagnostic ultrasound, the latter while participants have closed their eyes during Stimulation. Here we sought to study potential alteration of a visual target (a white crosshair) due to application of diagnostic ultrasound to the visual cortex. We applied a randomized series of actual or sham diagnostic ultrasound to the visual cortex of healthy participants while they stared at a visual target, with the ultrasound device placed where TMS (...) elicited phosphenes. These participants observed percepts 7 out of 10 times, consisting of extra or extensions of lines relative to the original crosshair, and additional colors. Observation of a percept occurred an average of 53.7 +/- 2.6% of the time over the course of the experiment for these participants. In contrast, 7 out of 10 participants exposed to sham-only diagnostic ultrasound observed comparable percepts an average of 36.3 +/ 1.9% of the time, a statistically significant difference (p < 0.00001). Moreover, on average, participants exposed to a combination of sham and actual ultrasound reported a net increase of 47.9 percentage points in the likelihood that they would report a visual effect by the end of the experiment. Our experiment demonstrated that a random combination of sham-only and actual diagnostic ultrasound applied to the visual cortex of participants increased the likelihood that they would observe visual effects, but not the type of effects, with that likelihood increasing over the course of the experiment. From this we conclude that repeated exposures by diagnostic ultrasound made the visual cortex more responsive to stimulation of their visual cortex by the visual target. These observations, consistent with other’s observation of effects of diagnostic ultrasound stimulation of human motor cortex and amygdala, as well as the FDA approved nature of diagnostic ultrasound, may lead to increased study of diagnostic ultrasound applied to human brain.

Moral bioenhancement is the attempt to improve human behavioral dispositions, especially in relation to the great ethical challenges of our age. To this end, scientists have hypothesised new molecules or even permanent changes in the genetic makeup to achieve such moral bioenhancement. The philosophical debate has focused on the permissibility and desirability of that enhancement and the possibility of making it mandatory, given the positive result that would follow. However, there might be another way to enhance the overall moral behavior (...) of us humans, namely that of targeting people with lower propensity to trust and altruism. Based on the theory of attachment, people who have a pattern of insecure attachment are less inclined to prosocial behavior. We know that these people are influenced by negative childhood memories: this negative emotional component may be erased or reduced by the administration of propranolol when the bad memory is reactivated, thereby improving prosocial skills. It could be objected that memory-editing might be a threat for the person’s identity and authenticity. However, if the notion of rigid identity is replaced by that of extended identity, this objection loses validity. If identity is understood as something that changes over time, moral bioenhancement through memory-editing seems indeed legitimate and even desirable. (shrink)

A growing number of small fashion entrepreneurs seek to offer an alternative to the mainstream fashion industry, which, in its obsession with novelty and growth, often ignores the costs to society and the environment. There is a need to develop a deeper understanding of how these fashion entrepreneurs may be agents for change in their industry. Using rich data from an in-depth study of 27 UK-based entrepreneurs, we offer such analysis, drawing on a novel framework that combines MacIntyre’s virtue ethics (...) scheme and Jonas’s responsibility imperative. We identify key virtues—passionate commitment, authenticity, humility, sharing and empowering, and temperance—which shape the entrepreneurs’ practices in line with their accepted and perceived responsibility for sustainability. These virtues shape the entrepreneurial processes that seek an active negotiation and harmonisation of sustainability and the demands of business. In particular, we pay attention to the different ways in which fashion entrepreneurs take responsibility for sustainability which ranges from a ‘growth for impact’ strategy to staying small and seeking impact through influence and replication. Conclusions are drawn on conceptualising the varieties of ‘postgrowth entrepreneurship’ that aligns the virtues of a deep-rooted sense of responsibility with business goals. This shows what can be possible and prefigures an alternative fashion industry. (shrink)

Currently much debate surrounds the significance of cross-cultural variation in mother-infant attachment. Is only one form of attachment “healthy,” or are different types of attachment adaptations to local socioecological conditions? Juvenile mortality rates have been promoted as important features of local environments that shape attachment, which in turn affects later reproductive strategies. To this we add fertility. Fertility changes the environment of a child by influencing the number of potential caregivers and competitors for care, and the cultural ethos regarding the (...) rights of children. Different combinations of fertility and mortality will likely give rise to different attachment forms, and only under one regime (low fertility and mortality) do we expect exclusivity in attachment.

Analytic metaphysics is usually considered a contemporary form of traditional, pre-Cartesian metaphysics. This paper examines the epistemic legitimacy of analytic metaphysics in the face of scientific dominance. While naturalized metaphysics has found its place within science, analytic metaphysics remains challenged. To meet the challenge, I propose interpreting analytic metaphysics as a form of logical inquiry, positioning logic as its foundation, similarly to how science grounds naturalized metaphysics. The argument is developed through three key points: (1) tracing the historical connection between (...) science and naturalized metaphysics on the one hand, and analytic metaphysics and philosophical logic on the other hand, (2) highlighting similarities between logic and metaphysics, and (3) demonstrating that contemporary analytic metaphysics often operates as a logical inquiry. I show that this strategy preserves classical options at the meta-metaphysical level, arguing that a view of logic as grounded in language is in a better position to safeguard the autonomy from science and the collapse into naturalized metaphysics.

In this paper I address the naturalistic assumptions in the contemporary philosophical debate about character. I begin with a brief reconstruction of the controversy between dispositionalists and situationists in moral psychology and then turn to Christian Miller’s recent proposal of a Mixed-Traits approach to character in Section I. Section II raises the familiar problem of explanatory circularity in the appeal to character traits and discusses Miller’s proposed solution in terms of grounding character traits in deeper dispositions to form beliefs and (...) desires. Section III introduces the notion of structural naturalism as the threefold underlying assumption in the contemporary debate. Section IV introduces a personalistic perspective on character following Edmund Husserl’s idea of the personalistic attitude. The following three sections (V, VI, and VII) propose alternatives to the threefold assumption of structural naturalism drawing on the work of Edmund Husserl, Edith Stein and Alexander Pfänder. In the conclusion I recapitulate my argument and emphasize how phenomenology could contribute valuable insights for a radical reconfiguration of the debate on character. (shrink)

One of the basic question we can ask about truth in a formal setting is what, if anything, we gain when we have a truth predicate at disposal. For example, does the expressive power of a language change or does the proof strength of a theory increase? Satisfaction classes are often described as complicated model theoretic constructions unable to give useful information toward the notion of truth from a general point of view. Their import is narrowed to a dimension of (...) pure technical utility and curiosity. Here I offer an application of satisfaction classes in order to show that they can have a relevant role in confronting proof theoretical equivalent theories of truth. (shrink)

One challenge while learning scientific concepts is to select relevant information and to integrate different representations of the learning content into one coherent mental model. Virtual reality learning environments offer new possibilities to support learners and foster learning processes. Whether learning in VR is successful, however, depends to a large extent on the design of the VRLE and the learners themselves. Hence, adding supportive elements in VRLEs, such as annotations, might facilitate the learning process by guiding attention and supporting the (...) selection of relevant information. Additionally, the mapping of pictorial and verbal information is eased by these annotations. The beneficial effect of annotations is highly dependent on learners' intrinsic motivation as intrinsic motivation while learning also affects the information selection and visual search patterns. In our experimental study, we compared two conditions: learning in a VRLE with or without annotations. We measured the learning outcome on three different levels. Additionally, we investigated intrinsic motivation as a moderator for the effect of annotations on learning outcome. We found no significant main effect of annotations on learning outcome. The moderating effect of intrinsic motivation for annotations on the overall learning outcome was significant. Our results imply that learners are either intrinsically motivated or need additional support by annotations as these support the selection of relevant information in the VRLE and therefore enable them to learn successfully. Which type or quantity of annotations supports learning processes best needs to be explored in future research. (shrink)

This paper aims to analyze one of the highest achievements of humankind, the classical tragedy, via the application of the heuristic paradigm proposed by Aristotle in his Physics, the fourfold determination of the concept of cause. This scientific methodology – one of the most effective viatica for a comprehensive response to the question of the nature of an object – informs the inquiry into the universal nature of tragedy, its hypercomplexity and hence its ethical and human relevance. Firstly, the concept (...) of tragedy is dissected into its four causes – material, formal, efficient and final; given that the object of research is at the same time tragedy in general and this specific tragedy , each cause is subdivided in two, a distal one and a proximal one . Then, the methodology of the four causes is applied to the formal cause alone, the tragic conflict, in an attempt to better understand tragedy’s quiddity. The results of this more specific causal determination are finally applied to the four causes of tragedy, supporting the hypothesis of a close relationship between hybris, amartia, tragic conflict and education of the phronesis.

Engelhardt’s critiques of “generic chaplaincy” rely on the argument that chaplains are secular; however, professionally certified chaplains must maintain ordination with an ecclesial body. Engelhardt’s concerns are better directed at the academic subfield that supports and trains chaplains: pastoral theology. That field is somewhat guilty of forced ecumenism because it attempts a universal theology rooted in experience and the social sciences rather than the authority of creeds, ecclesial bodies, or traditions. Pastoral theology makes too many sacrifices to the authority of (...) the behavioral sciences without sufficient appreciation for sacramental theology and the spiritual bonds that rituals effect in communities of shared belief. In this model, ritual is reduced to its instrumental value in addressing the emotional needs of patients rather than viewed as efficacious spiritual care. Chaplains should take a holistic approach to theology so that they can better identify the duties and scope of interfaith spiritual care. (shrink)

Specific studies of the “situated ethics” of international surrogacy that address the structural conditions and local moral economies that sustain the trade are needed. In this essay, I describe the intimate industry of surrogacy in Thailand, exploring the local moral economy in which surrogacy is described as a form of Buddhist merit making and an opportunity to provide for one’s own children. This offers a further example of how other ethical values beyond the strictly economic are negotiated in commercial surrogacy (...) relationships. Situated ethics allow us to locate and understand the tensions, competing logics, and contradictions within ethical practices. (shrink)

How do religions and languages interact? This inquiry prompts us to explore not only various religious traditions and their respective languages but also the plurality of linguistic codes. When examined in relation to religious experiences, concepts, and identities, this linguistic plurality becomes interconnected, giving rise to a pluralism that taps into religious paths, practices, texts, stories, and encounters. Reflecting upon the interplay of languages within religious contexts takes us on a journey beyond Babel – a journey beyond a fragmented plurality (...) and toward a polyphonic and embodied unity. The chapters of the book Beyond Babel: Religion and Linguistic Pluralism illuminate different stages of this journey, spanning from the boundaries of language in religious contexts to novel forms of interreligious dialogue. The exploration encompasses translation between sacred and secular languages, as well as the intricate interconnections between religious and scientific codes, and it culminates in an exploration of religion within formal languages.

Resumen: El objetivo de este artículo es estudiar la inducción analítica como método científico de investigación, es decir, como modo válido de hacer ciencia. En 1934, su creador, el filósofo y sociólogo Florian Znaniecki, afirmó que este era el método que debía ser adoptado en toda investigación sociológica. Su relevancia radica en que se propone encontrar explicaciones globales de los fenómenos sociales a partir de la utilización de técnicas cualitativas de investigación. Aquí adopto una perspectiva histórica que permite inscribir su (...) emergencia y evolución en un contexto mayor del desarrollo de metodologías cualitativas en sociología, para luego reflexionar sobre sus presupuestos epistemológicos y las críticas de las que fue objeto. Por último, realizo un balance de los aportes de esta metodología a la disciplina.: The aim of this article is to study analytic induction as a scientific research method, that is, as a valid way of making science. In 1934, the philosopher and sociologist Florian Znaniecki, its creator, referred to this methodology as the method that should be adopted by any sociological research. Its relevance lies on the fact that its goal is to find global explanations to social phenomena by using qualitative research techniques. I adopt a historical perspective to inscribe this method’s emergency and evolution in a larger context of the development of qualitative methods in sociology, and then reflect upon its epistemological basis and the criticisms made in relation to it. Finally, I evaluate this method’s contributions to the discipline. (shrink)

In recent years and months, human stem cell research has dominated many scientists' interests, the media, public debate, and social policy. This paper aims to consider, first, the major scientific data on stem cell research that are available. Second, I reflect on them by examining how they shaped policies in Europe and the United States. I also point to current changes in policy-making concerning the creation of ad hoc committees to address this novel issue and how, in a few instances, (...) different ethical positions are part of the documents produced. In other words, diverse approaches are not solved but kept in tension. Finally, I suggest that the current state of research on human stem cell will benefit from an ethics of risk. (shrink)

In der zeitgenössischen Erkenntnistheorie ist die Idee verbreitet, dass der Erwerb von Wissen davon abhängig ist, dass das Subjekt des Wissens an einer bestimmten Lebensform teilhat, die grundlegender als sein Wissen ist. Das ist eine Lesart der Position Wittgensteins, deren exemplarischer Vertreter etwa Stanley Cavell ist. Meine These dagegen lautet, dass die Lebensformtheorie einem erkenntnistheoretischen Dogma aufruht, dessen Überwindung Wittgensteins eigentliches Anliegen war: Es ist das Dogma, dass die grundlegende Bedeutung des Wissensbegriffs in der Beschreibung eines einzelnen Aktes besteht, und (...) nicht in der Beschreibung von etwas, das auf einer logisch anderen Ebene steht: nämlich einer Fähigkeit. Damit soll nicht bestritten werden, dass die Idee einer bestimmten Lebensform wesentlich ist für die Beschreibung erkenntnisfähiger Subjekte. Doch diese ist nicht grundlegender als die Idee des Wissens selbst. (shrink)
