ABSTRACTThe eyes are extremely important for communication. The muscles around the eyes express emotional states and the size of the pupil signals whether a person is aroused and alert or bored and fatigued. Pupil size is an overlooked social signal, yet is readily picked up by observers. Observers mirror their own pupil sizes in response, which can influence social impressions. In a landmark study by Hess [1975. The role of pupil size in communication. Scientific American, 233, 110–119] it was shown (...) that individuals with large pupils are perceived more positively than individuals with small pupils. In that behavioral study, participants were asked to draw pupils in line drawings of faces with empty irises and they drew large pupils in the happy face, and small ones in the angry face. The current study tested 579 participants and extended this work by showing that this association between large pupils and a positive impression develops over age and is absent in... (shrink)

While new regulations obligate or recommend people to wear medical masks at public places to prevent further spread of the Covid-19 virus, there are still open questions as to what face coverage does to social emotional communication. Previous research on the effects of wearing veils or face-covering niqabs showed that covering of the mouth led to the attribution of negative emotions and to the perception of less intense positive emotions. The current study compares a sample from the Netherlands with a (...) sample from the United Arab Emirates on their perception of emotions from faces covered by a niqab, censoring black bars, or uncovered faces. The results show that covering the mouth area leads to greater anxiety in participants in both countries. Furthermore, although participants did not report greater decoding difficulties for faces that were covered as compared to fully visible, results show that face coverage did influence emotion perception. Specifically, happiness and anger were perceived as being less intense. Further, face coverage by a niqab, as compared to black bars, yielded lower emotional intensity ratings. We conclude that face coverage in particular can modulate the perception of emotions, but that affective contextual cues may play a role as well. (shrink)

ABSTRACTThe eyes reveal important social messages, such as emotions and whether a person is aroused and interested or bored and fatigued. A growing body of research has also shown that individuals with large pupils are generally evaluated positively by observers, while those with small pupils are perceived negatively. Here, we examined whether observed pupil size influences approach-avoidance tendencies. Participants performed an Approach-Avoidance Task using faces with large and small pupil sizes. Results showed that pupil size influences the accuracy of arm (...) movements. Specifically, individuals were less prone to approach a face with small pupils than a face with large pupils. Conversely, participants were less prone to avoid a face with large pupils than a face with small pupils. Collectively, these findings suggest that perceivers attend to a facial cue – pupil size – when interacting with others. (shrink)

Changes in pupil size can reflect social interest or affect, and tend to get mimicked by observers during eye contact. Pupil mimicry has recently been observed in young infants, whereas it is unkno...

In the fearful ape hypothesis, Grossmann argues that heightened fearfulness increases human-unique cooperation. We suggest that this conclusion, however, may be premature. In particular, we question Grossmann's singling out of fear as the affective trait that enhances cooperative care. Additionally, we problematize the extent to which heightened fearfulness in humans, and its association with human-unique cooperation, are supported empirically.

In their “social contextual view” of emotional mimicry, authors Hess and Fischer (2022) put forward emotional mimicry as a social regulator, considering it a social act, bound to certain affiliative contexts or goals. In this commentary, we argue that the core function of mimicry is to ease predicting conspecifics’ behaviours and the environment, and that as a consequence, this often smoothens social interactions. Accordingly, we make three main points. First, we argue that there is no good reason to believe that (...) the mimicry of negative expressions is fundamentally different than the mimicry of positive or ambiguous or autonomic expressions. Second, we give examples of empirical evidence that mimicry is not always a social act. Third, we show that mimicry has primary benefits for the mimicker. As such, we will briefly summarise and elaborate on the relevant findings in these respects, and propose a comparative, multi-method and ecologically valid approach which can explain the multifaceted character of the phenomenon.

Aristotle's study of the natural world plays a tremendously important part in his philosophical thought. He was very interested in the phenomena of motion, causation, place and time, and teleology, and his theoretical materials in this area are collected in his Physics, a treatise of eight books which has been very influential on later thinkers. This volume of new essays provides cutting-edge research on Aristotle's Physics, taking into account recent changes in the field of Aristotle in terms of its understanding (...) of key concepts and preferred methodology. The contributions reassess the key concepts of the treatise, reconstruct Aristotle's methods for the study of nature, and determine the boundaries of his natural philosophy. Due to the foundational nature of Aristotle's Physics itself, the volume will be a must-read for all scholars working on Aristotle. (shrink)

During the second half of the twentieth century, several philosophers of technology argued that their predecessors had reflected too abstractly and pessimistically on technology. In the view of these critics, one should study technologies empirically in order to fully understand them. They developed several strategies to empirically inform the philosophy of technology and called their new approach the empirical turn. However, they provide insufficient indications of what exactly is meant by empirical study in their work. This leads to the critical (...) question of what counts as an empirically informed philosophy of technology in the empirical turn. In order to answer this question, we first elaborate on the problems that the empirical turn philosophers tried to address; secondly, we sketch their solutions, and, thirdly, we critically discuss their conceptions of empirical study. Our critical analysis of the empirical turn contributes to new efforts to engage in an empirically informed philosophy of technology. (shrink)

To reduce negative emotional responses and to stimulate prosociality, constructive journalism promotes the inclusion of positive emotions and solutions in news. This study experimentally tested whether including those elements indeed increased prosocial intentions and behavior among children, and whether negative emotions and self-efficacy are mediators in this regard. To this end, children were exposed to an emotion-based, solution-based, or non-constructive news video. Results showed that emotion-based and solution-based news reduced children’s negative emotions compared to non-constructive news. No direct effects for (...) prosocial intentions were found, but solution-based news led to less prosocial behavior than emotion-based and non-constructive news. Moreover, negative emotions served as a mediator, self-efficacy did not. The more negative emotions were elicited by a news story, the higher the prosocial intentions and behavior. In conclusion, a constructive style of reporting helps to reduce children’s negative emotional responses but subsequently hinders prosociality. (shrink)

In Aristotle's teleological view of the world, natural things come to be and are present for the sake of some function or end. Whereas much of recent scholarship has focused on uncovering the physical underpinnings of Aristotle's teleology and its contrasts with his notions of chance and necessity, this book examines Aristotle's use of the theory of natural teleology in producing explanations of natural phenomena. Close analyses of Aristotle's natural treatises and his Posterior Analytics show what methods are used for (...) the discovery of functions or ends that figure in teleological explanations, how these explanations are structured, and how well they work in making sense of phenomena. The book will be valuable for all who are interested in Aristotle's natural science, his philosophy of science, and his biology. (shrink)

This book discusses Aristotle's biological views about 'natural character traits' and their importance for moral development. It provides a new, comprehensive account of the physiological underpinnings of moral development and shows that the biological account of natural character provides the conceptual and ideological foundation for Aristotle's ethical views about habituation.

This article examines whether there are differences between older and younger adults in recall and liking of arousing television commercials. As hypothesized, the experiment demonstrated that older adults remembered brands and products in calm commercials better than in arousing commercials, and they also liked calm commercials more. In contrast, younger adults remembered brands and products in arousing commercials better and they liked these commercials more. In addition, linear relationships showed that for older adults arousal deteriorates their recall and liking, whereas (...) for younger adults arousal – up to a certain point – is beneficial. These findings strongly suggest that advertising effects found in younger samples are unlikely to be the same for older target groups. An important practical implication is that it currently seems wise to make commercials targeted towards older adults calm instead of arousing when the aim is to generate brand recall and liking.

Despite the renewed interest in Aristotle’s Generation of Animals in recent years, the subject matter of GA V, its preferred mode(s) of explanation, and its place in the treatise as a whole remain misunderstood. Scholars focus on GA I-IV, which explain animal generation in terms of efficient-final causation, but dismiss GA V as a mere appendix, thinking it to concern (a) individual, accidental differences among animals, which are (b) purely materially necessitated, and (c) are only tangentially related to the topics (...) discussed in the earlier books. In this paper, we defend an alternative and more integrated account of GA V by closely examining Aristotle’s methodological introduction in GA V.1 778a16-b19 and his teleological explanation of the differences of teeth in GA V.8. We argue for the unity of both GA V and of GA as a whole and present a more nuanced theory of teleological explanation in Aristotle’s biology. (shrink)

In this paper, I offer three suggestions regarding the role of Aristotle’s concept of analogy in biology as alternatives to the views defended by Devin Henry. First, I argue that the concept of analogy in Aristotle’s biological treatises points to a similarity in capacity between parts. Second, that it is mostly of methodological importance for the practice of explanation rather than for the practice of classification. And finally, that it is used with regard to parts that are visibly different and (...) incommensurate rather to parts that possess different material natures. (shrink)

It is a commonplace in Aristotelian scholarship that the forms of living beings and the animal species to which they give rise are “fixed.” However, Aristotle’s biological works often stress the flexibility of nature during the development of animals. The purpose of this paper is twofold: first, to delineate the range of flexibility that Aristotle takes natures to have in the design of animals; and second, to draw out the implications of this for Aristotle’s embryology and theory of natural teleology.

This paper argues that Aristotle’s representation of mothers and motherly love in two separate arguments about friendship in his ethical treatises are not to be read as positive valuations of mothering and its associated traits but rather as perpetuating the common Greek animalization of women. For the deep love and the complex care and practical intelligence human mothers exhibit for their children are according to Aristotle rooted in the biological capacities that they share with non-human animals. Importantly, these capacities are (...) instinctual rather than chosen and grounded primarily in women’s perceptive soul rather than in their rational soul. By emphasizing the naturalness and the affective character of motherly love in his ethics, Aristotle assimilates human mothers to animal ones and depicts their excellence in mothering as a biological virtue rather than a moral one.

While Aristotle is mostly famous as the father of natural teleology, De Groot sets out to offer us a picture of the “other,” hitherto neglected Aristotle, whose natural science is thoroughly influenced by mechanistic procedures and ideas. Her monograph is impressive: it provides a wealth of detailed and philosophically rich discussions of sometimes overlooked Aristotelian texts, diagrams, and tables that help visualize the often technical materials she discusses, and bold and original claims that will perhaps not convince everyone, but that (...) will need to be taken into account in future studies of Aristotle’s natural philosophy. By drawing attention to the operation of mechanical notions... (shrink)

Es ist ein zentraler Grundsatz der aristotelischen Naturphilosophie, dass die Natur stets um eines bestimmten Zweckes willen tätig ist: Jedes Ding, das von Natur aus besteht, sich verändert oder entsteht, tut dies – solange es nicht daran gehindert wird – um eines bestimmten Zweckes bzw. um einer bestimmten Funktion willen. In diesem Zweck bzw. in dieser Funktion besteht die Zweck- oder auch Finalursache des Dinges, welches dann seinerseits die Vermögen, Struktur und Teile, die es besitzt, um willen der Zweckursache besitzt. (...) In der modernen Literatur nennt man diesen aristotelischen Grundsatz von der Zweckorientiertheit des Natürlichen Aristoteles’ Lehre von der natürlichen Teleologie. Es ist allerdings wichtig, sich klarzumachen, dass der Ausdruck ›Teleologie‹ erst im 18. Jh. durch den deutschen Philosophen Christian Wolff geprägt wurde. (shrink)

This volume collects Late Ancient, Byzantine and Medieval appropriations of Aristotle's Posterior Analytics, addressing the logic of inquiry, concept formation, the question whether metaphysics is a science, and the theory of demonstration.

As the editors of this excellent little volume point out from the outset, Aristotle’s Physics VII.3 is a curious, difficult, and—sadly—mostly neglected chapter. On the one hand, the chapter discusses quite important matters. Offering one of the lengthiest discussions of qualitative change in the Aristotelian corpus, it starts out by restricting this type of change—not to changes in any of the four types of quality Aristotle had distinguished in Categories 8—but to change in perceptual qualities only . It then proceeds (...) by demonstrating that two seeming counterexamples to this refined notion of qualitative change—namely, items taking on figures or shapes, and the taking on and casting off of states —are not in fact cases of qualitative change, even if their occurrence depends on qualitative changes taking place in something else. In the meantime, it offers a rare physiological account of the acquisition and loss of the ethical and intellectual virtues, thereby making the chapter not only crucial for our understanding of Aristotle’s physics and metaphysics but also for his moral psychology and ethics. On the other hand, the chapter is demanding, does not seem to fit in well within the argument of Physics VII as a whole , and the Greek has been handed down to us in two different versions. (shrink)
