Triggering social interactions: chimpanzees respond to imitation by a humanoid robot and request responses from it

Even the most rudimentary social cues may evoke affiliative responses in humans and promote social communication and cohesion. The present work tested whether such cues of an agent may also promote communicative interactions in a nonhuman primate species, by examining interaction-promoting behaviours in chimpanzees. Here, chimpanzees were tested during interactions with an interactive humanoid robot, which showed simple bodily movements and sent out calls. The results revealed that chimpanzees exhibited two types of interaction-promoting behaviours during relaxed or playful contexts. First, the chimpanzees showed prolonged active interest when they were imitated by the robot. Second, the subjects requested ‘social’ responses from the robot, i.e. by showing play invitations and offering toys or other objects. This study thus provides evidence that even rudimentary cues of a robotic agent may promote social interactions in chimpanzees, like in humans. Such simple and frequent social interactions most likely provided a foundation for sophisticated forms of affiliative communication to emerge.     

When the Going Gets Tough: The “Why” of Goal Striving Matters

No prior research has examined how motivation for goal striving influences persistence in the face of increasing goal difficulty. This research examined the role of self‐reported (Study 1) and primed (Study 2) autonomous and controlled motives in predicting objectively assessed persistence during the pursuit of an increasingly difficult goal. In Study 1, 100 British athletes (64 males; M_age = 19.89 years, SD_age = 2.43) pursued a goal of increasing difficulty on a cycle ergometer. In Study 2, 90 British athletes (43 males; M_age = 19.63 years, SD_age = 1.14) engaged in the same task, but their motivation was primed by asking them to observe a video of an actor describing her or his involvement in an unrelated study. In Study 1, self‐reported autonomous goal motives predicted goal persistence via challenge appraisals and task‐based coping. In contrast, controlled goal motives predicted threat appraisals and disengagement coping, which, in turn, was a negative predictor of persistence. In Study 2, primed autonomous (compared to controlled) goal motives predicted greater persistence, positive affect, and future interest for task engagement. The findings underscore the importance of autonomous motivation for behavioral investment in the face of increased goal difficulty.     

In Defense of Experience

This article studies our philosophical understanding of experience in order to question the current political and theoretical dismissal of experiential accounts in feminist theory. The focus is on Joan Scott's critique of experience, but the philosophical issues animating the discussion go beyond Scott's work and concern the future of feminist theory and politics more generally. I ask what it means for feminist theory to redefine experience as a linguistic event the way Scott suggests. I attempt to demonstrate that the consequences that she draws from such a theoretical move are both philosophically and politically problematic. A critical study of the evidence of experience does not have to imply metaphysical or epistemological foundationalism, as Scott claims, but on the contrary, such a study is indispensable for challenging them. We must hold onto experience as an important resource for contesting sexist discourses and oppressive conceptual schemas.     

Mixed Methods in Youth Purpose: An Examination of Adolescent Self-Regulation and Purpose

Utilizing a relational developmental systems approach to examining character strengths, this article examines the connection between adolescents’ intentional self-regulation (ISR) with youth sense of purpose, using data from a large-scale evaluation of a youth development program in Scotland. Data were triangulated from multiple sources, including youth surveys and interviews as well as teacher assessments. Surveys were collected from 783 S2 (approximately seventh grade) pupils; teacher survey data were collected for 732 of these pupils. Telephone interviews were conducted with a subset of 29 adolescents. The data were analyzed with an innovative mixed-methods technique that allows qualitative interview data to underscore consistencies and disconnects with quantitative findings from both teacher and adolescent surveys. Results demonstrate a strong connection between ISR and purpose and many consistencies across measures of purpose.     

“Violence” in medicine: necessary and unnecessary,intentional and unintentional

We are more used to thinking of medicine in relation to the ways that it alleviates the effects of violence. Yet an important thread in the academic literature acknowledges that medicine can also be responsible for perpetuating violence, albeit unintentionally, against the very individuals it intends to help. In this essay, I discuss definitions of violence, emphasizing the importance of understanding the term not only as a physical perpetration but as an act of power of one person over another. I next explore the paradox of a healing profession that is permeated with violence sometimes necessary, often unintentional, and almost always unrecognized. Identifying the construct of “physician arrogance” as contributory to violence, I go on to identify different manifestations of violence in a medical context, including violence to the body; structural violence; metaphoric violence; and the practice of speaking to or about patients (and others in the healthcare system in ways that minimize or disrespect their full humanity. I further suggest possible explanations for the origins of these kinds of violence in physicians, including the fear of suffering and death in relation to vicarious trauma and the consequent concept of “killing suffering”; as well as why patients might be willing to accept such violence directed toward them. I conclude with brief recommendations for attending to root causes of violence, both within societal and institutional structures, and within ourselves, offering the model of the wounded healer.

Finishing on time: When do predictions influence completion times?

People typically predict they will finish projects earlier than they do. Whereas previous research has examined the determinants of this prediction bias, the present research explored potential consequences for behavior. In particular, we examined whether and when task completion predictions influence actual completion times. In four experiments we used anchoring manipulations to induce participants to make relatively early or late task completion predictions, and then examined when they started and/or finished the target tasks. As hypothesized, the prediction manipulation influenced completion times under certain conditions defined by the nature of the target task. Manipulated predictions affected completion times of closed tasks, defined as tasks carried out within a single, continuous session but not of open tasks, defined as tasks requiring multiple work sessions. This implies that task completion predictions help to initiate action, but their impact diminishes over the course of extensive, multi-stage projects.     

The relationships between processing facial identity,emotional expression,facial speech,and gaze direction during development

Four experiments were conducted with 5- to 11-year-olds and adults to investigate whether facial identity, facial speech, emotional expression, and gaze direction are processed independently of or in interaction with one another. In a computer-based, speeded sorting task, participants sorted faces according to facial identity while disregarding facial speech, emotional expression, and gaze direction or, alternatively, according to facial speech, emotional expression, and gaze direction while disregarding facial identity. Reaction times showed that children and adults were able to direct their attention selectively to facial identity despite variations of other kinds of face information, but when sorting according to facial speech and emotional expression, they were unable to ignore facial identity. In contrast, gaze direction could be processed independently of facial identity in all age groups. Apart from shorter reaction times and fewer classification errors, no substantial change in processing facial information was found to be correlated with age. We conclude that adult-like face processing routes are employed from 5 years of age onward.
