We take up issues raised in the commentaries about our proposal that social robots are depictions of social agents. Among these issues are the realism of social agents, experiencing robots, communicating with robots, anthropomorphism, and attributing traits to robots. We end with comments about the future of social robots.

Assurance of Learning (AoL) is a critical component of AACSB accreditation because students need to demonstrate skills acquired in the programs they enroll in. The purpose of this paper is to describe how a business school developed its ethics assessment program to fulfill the requirement of AoL when seeking AACSB accreditation. Three learning goals were identified based on the literature, assessment rubrics were created based on learning goals, and a Harvard Business Case was used as the assessment tool. The result (...) of the first round of summative assessments showed that almost all students at least met the standard of these three learning goals. To close the loop, an ethics module and a one-hour video were added to a junior-level course. In the second round of summative assessment, we added a marginal level of competency to the rubric. We conclude with a plan for future student learning and assessment. (shrink)

Social robots serve people as tutors, caretakers, receptionists, companions, and other social agents. People know that the robots are mechanical artifacts, yet they interact with them as if they were actual agents. How is this possible? The proposal here is that people construe social robots not as social agentsper se, but asdepictionsof social agents. They interpret them much as they interpret ventriloquist dummies, hand puppets, virtual assistants, and other interactive depictions of people and animals. Depictions as a class consist of (...) three physical scenes with part-by-part mappings between them: (a) a base scene (the raw physical artifact), (b) the depiction proper (the artifact construed as a depiction), and (c) the scene depicted (the scene people are to imagine). With social robots, evidence shows people form the same three scenes plus mappings: They perceive the raw machinery of a robot, construe it as a depiction of a character, and, using the depiction as a guide, engage in the pretense that they are interacting with the character depicted. With social robots, people also recognize three classes of agents – the characters depicted, the intended recipients of the depictions (those who view or interact with the robots), and the authorities responsible for the robots (the designers, makers, and owners). Construing social robots as depictions, we argue, accounts for many phenomena not covered by alternative models. (shrink)

Abraham’s “leadership by example” provides a template for business leaders to implement a tone at the top based on a balance of tzedek (righteousness) and mishpat (legal judgement). The former expresses the generosity of spirit required of leaders, while the latter expresses the sound judgement in conformity with both ethics and enacted law. We relate the two constructs to several contemporary theories of justice and jurisprudence. We also relate the development of Abrahamic Justice in the Jewish tradition from antiquity through (...) Maimonides in the middle ages. We draw insight from this tradition to answer a contemporary business ethics question: Do corporate managers violate their fiduciary duty to shareholders if they refuse to engage in legal tax avoidance?

In the present article we argue that emotional interactions are not appropriately captured in present emotion research and theorizing. Emotional stimuli or antecedents are dynamic and change over time because they often interact and have a specific relationship with the subject. Earlier emotional interactions may, for example, intensify later emotional reactions to a specific person, or our anger reactions towards powerful or powerless others may differ considerably. Thus, we suggest that such social factors not only affect the intensity, but also (...) the nature of emotional experiences and expressions, and specifically the nature of the social movement (e.g., moving towards, away, or against). We discuss different processes that are implicated in the relation between the social environment and our emotions, describe how emotional expressions shape social behavior, and provide suggestions for incorporating the social dimension of emotion in future research.

Questions about the validity of eye fixations in the blocks task as a memory indicator are discussed. Examples from reading research illustrate the influence of extraneous factors.

In the context of item response theory, linking the scales of two measurement points is a prerequisite to examine a change in competence over time. In educational large-scale assessments, non-identical test forms sharing a number of anchor-items are frequently scaled and linked using two− or three-parametric item response models. However, if item pools are limited and/or sample sizes are small to medium, the sparser Rasch model is a suitable alternative regarding the precision of parameter estimation. As the Rasch model implies (...) stricter assumptions about the response process, a violation of these assumptions may manifest as model misfit in form of item discrimination parameters empirically deviating from their fixed value of one. The present simulation study investigated the performance of four IRT linking methods—fixed parameter calibration, mean/mean linking, weighted mean/mean linking, and concurrent calibration—applied to Rasch-scaled data with a small item pool. Moreover, the number of anchor items required in the absence/presence of moderate model misfit was investigated in small to medium sample sizes. Effects on the link outcome were operationalized as bias, relative bias, and root mean square error of the estimated sample mean and variance of the latent variable. In the light of this limited context, concurrent calibration had substantial convergence issues, while the other methods resulted in an overall satisfying and similar parameter recovery—even in the presence of moderate model misfit. Our findings suggest that in case of model misfit, the share of anchor items should exceed 20% as is currently proposed in the literature. Future studies should further investigate the effects of anchor item composition regarding unbalanced model misfit. (shrink)

Four Views on Free Will is a robust and careful debate about free will, how it interacts with determinism and indeterminism, and whether we have it or not. Providing the most up-to-date account of four major positions in the free will debate, the second edition of this classic text presents the opposing perspectives of renowned philosophers John Martin Fischer, Robert Kane, Derk Pereboom, and Manuel Vargas. -/- Substantially revised throughout, this new volume contains eight in-depth chapters, almost entirely rewritten (...) for the new edition, in which the authors state their different positions on the debate, offer insights into how their views have evolved over the past fifteen years, respond to recent critical literature in the field, and interact and engage with each other in dialogue. In the first four chapters the authors defend their distinctive views about free will: libertarianism, compatibilism, hard incompatibilism, and revisionism. The subsequent four chapters consist of direct replies by each of the authors to the other three. (shrink)

Social robots are increasingly used in different areas of society such as public health, elderly care, education, and commerce. They have also been successfully employed in autism spectrum disorders therapy with children. Humans strive to find in them not only assistants but also friends. Although forms and functionalities of such robots vary, there is a strong tendency to anthropomorphize artificial agents, making them look and behave as human as possible and imputing human attributes to them. The more human a robot (...) looks, the more appealing it will be considered by humans. However, this linear link between likeness and liking only holds to the point where a feeling of strangeness and eeriness emerges. We discuss possible explanations of this so-called uncanny valley phenomenon that emerges in human–robot interaction. We also touch upon important ethical questions surrounding human–robot interaction in different social settings, such as elderly care or autism spectrum disorders therapy. (shrink)

I focus on some differences between negative emotional states and how they are coped with in explaining different cardiac risks. The different cognitive, motivational, and physiological characteristics of emotions imply different appraisals of the negative event, and different resources to cope with the event. Cardiovascular activity depends on these different appraisals and coping strategies. For example, cortisol levels have shown to be differently associated with anger and fear responses to social stress. In addition, different ways to regulate one’s emotions are (...) also associated with different bodily responses that may increase or decrease cardiac risks. Future research should not only examine different emotions to stressors, but also more long-term regulation strategies and coping resources, such as self-esteem. (shrink)

The study has two objectives: to introduce grip force recording as a new technique for studying embodied numerical processing; and to demonstrate how three competing accounts of numerical magnitude representation can be tested by using this new technique: the Mental Number Line, A Theory of Magnitude and Embodied Cognition account. While 26 healthy adults processed visually presented single digits in a go/no-go n-back paradigm, their passive holding forces for two small sensors were recorded in both hands. Spontaneous and unconscious grip (...) force changes related to number magnitude occurred in the left hand already 100–140 ms after stimulus presentation and continued systematically. Our results support a two-step model of number processing where an initial stage is related to the automatic activation of all stimulus properties whereas a later stage consists of deeper conscious processing of the stimulus. This interpretation generalizes previous work with linguistic stimuli and elaborates the timeline of embodied cognition. We hope that the use of grip force recording will advance the field of numerical cognition research. (shrink)

The reliable covariation between numerosity and spatial extent is considered as a strong constraint for inferring the successor principle in numerical cognition. We suggest that children can derive a general number concept from the (experientially) infinite succession of spatial positions during object manipulation.

Inappropriate saccades are prevented by fixation and by voluntary attention. The fixation system inhibits the saccade system. Like monkeys without a fixation system, humans with a weak fixation system produce many express saccades and cannot suppress prosaccades in an antisaccade task. With permanent attention to a peripheral location only a few express saccades to a stimulus at this location can be elicited: the sustained component of attention acts like fixation. When attention is captured by a precue, more express saccades are (...) obtained: the stimulus-driven component of attention facilitates saccade generation. If the cue correctly indicates the direction for an antisaccade error rate and latencies are increased. (shrink)

In this reply, I discuss some important issues raised in two commentaries. One relates to the distinction between hate and revenge, which also touches upon the more general problem of the usefulness of distinguishing between various related emotions. I argue that emotion researchers need to define specific emotions carefully in order to be able to examine such emotions without necessarily using emotion words. A second comment focusses on the factors influencing the development of hate over time. The question is whether (...) there is an intrapersonal mechanism leading to an increase or decrease of hate over time. I think it is the social environment that is essential in the maintenance of hate. (shrink)

ABSTRACTPosed stimuli dominate the study of nonverbal communication of emotion, but concerns have been raised that the use of posed stimuli may inflate recognition accuracy relative to spontaneous expressions. Here, we compare recognition of emotions from spontaneous expressions with that of matched posed stimuli. Participants made forced-choice judgments about the expressed emotion and whether the expression was spontaneous, and rated expressions on intensity and prototypicality. Listeners were able to accurately infer emotions from both posed and spontaneous expressions, from auditory, visual, (...) and audiovisual cues. Furthermore, perceived intensity and prototypicality were found to play a role in the accurate recognition of emotion, particularly from spontaneous expressions. Our findings demonstrate that perceivers can reliably recognise emotions from spontaneous expressions, and that depending on the comparison set, recognition levels can even be equivalent to that o...

Small numbers are spontaneously associated with left space and larger numbers with right space (the SNARC effect), for example when classifying numbers by parity. This effect is often attributed to reading habits but a causal link has so far never been documented. We report that bilingual Russian-Hebrew readers show a SNARC effect after reading Cyrillic script (from left-to-right) that is significantly reduced after reading Hebrew script (from right-to-left). In contrast, they have similar SNARC effects after listening to texts in either (...) language. These results support the view that spatially directional scanning habits contribute to the spatial association of numbers but also emphasize its flexibility. (shrink)

We have evolved to become who we are, at least in part, due to our general drive to create new things and ideas. When seeking to improve our creations, ideas, or situations, we systematically overlook opportunities to perform subtractive changes. For example, when tasked with giving feedback on an academic paper, reviewers will tend to suggest additional explanations and analyses rather than delete existing ones. Here, we show that this addition bias is systematically reflected in English language statistics along several (...) distinct dimensions. First, we show that words associated with an increase in quantity or number (e.g., add, addition, more, most) are more frequent than words associated with a decrease in quantity or number (e.g., subtract, subtraction, less, least). Second, we show that in binomial expressions, addition-related words are mentioned first, that is, add and subtract rather than subtract and add. Third, we show that the distributional semantics of verbs of change, such as to improve and to transform, overlap more with the distributional semantics of add/increase than subtract/decrease, which suggests that change verbs are implicitly biased toward addition. Fourth, addition-related words have more positive connotations than subtraction-related words. Fifth, we demonstrate that state-of-the-art large language models, such as the Generative Pre-trained Transformer (GPT-3), are also biased toward addition. We discuss the implications of our results for research on cognitive biases and decision-making. (shrink)
