Physiological and self-reported disgust reactions to obesity

There is accumulating evidence that disgust plays an important role in prejudice toward individuals with obesity, but that research is primarily based on self-reported emotions. In four studies, we examined whether participants displayed a physiological marker of disgust (i.e. levator labii activity recorded using facial electromyography) in response to images of obese individuals, and whether these responses corresponded with their self-reported disgust to those images. All four studies showed the predicted self-reported disgust response toward images of obese individuals. Study 1 further showed that participants exhibited more levator activity to images of obese individuals than to neutral images. However, Studies 2–4 failed to provide any evidence that the targets’ body size affected levator responses. These findings suggest that disgust may operate at multiple levels, and that the disgust response to images of obese individuals may be more of a cognitive-conceptual one than a physiological one.     

The role of pupil size in communication. Is there room for learning?

The 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(5), 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 (aged 4–80 years old) and extended this work by showing that this association between large (small) pupils and a positive (negative) impression develops over age and is absent in children. Several explanations for how individuals through interactions with close others learn that large pupils mean care, interest and attention and small pupils the opposite, are discussed. To conclude, this study shows that pupil size and emotion perception are intertwined but that their relationship develops over age.     

The bedside manner of homo economicus: How and why priming an economic schema reduces compassion

We investigate how, why and when activating economic schemas reduces the compassion that individuals extend to others in need when delivering bad news. Across three experiments, we show that unobtrusively priming economic schemas decreases the compassion that individuals express to others in need, that this effect is mediated by dampened feelings of empathy and heightened perceptions of unprofessionalism, and that it is circumscribed to bad news that has economic implications. We discuss implications for theory and research on schemas, procedural justice, emotion expression, and prosocial behavior.     

Maternal Expressive Style and Children's Emotional Development

Maternal expressive styles, based on a combination of positive and negative expressive patterns, were identified at two points in time and related to multiple aspects of preschool children's emotional development. Mother–child pairs from 260 families participated when the children were 3 years old, and 240 participated again at aged 4 years. Expressive styles were identified at age 3 using cluster analysis, replicated at age 4 and examined in relation to children's emotional understanding, expressiveness and regulation. Three expressive styles were identified: high positive/low negative, very low positive/average negative and average positive/very high negative. Cluster membership was stable in 63% of families from age 3 to 4 years; no systematic patterns of change were evident in the remaining families. Expressive style was related to aspects of children's emotional expression at 3 years and to emotion expression and regulation at 4 years. Children's expressiveness and regulation at age 3 were also related to changes in mothers' expressive styles over 1 year. Identifying mothers' expressive styles provides a unique way to understand the potential role of the emotional climates in which preschool‐aged children learn to express and regulate their own emotions.

Is psychoanalysis a matter of subjectivation?

We are not born subject but become one, in a two‐and‐fro process between what is played out on the intrapsychic stage and the field of intersubjectivation. The author proposes to examine two of the main movements of psychic life brought into play in this process. In the domain of the ‘subjectivating link’, becoming a subject depends on the relationship with another, authentically taken into account as a desiring subject and not simply as an object for oneself. In the course of history, this intersubjectivation is only internalized as a lasting preconscious predisposition if sufficient trust is established in the possibility of mutual recognition. When this perspective recedes, the subject tends to fall back on narcissistic positions, in search of an end to lack. Such a narcissistic tendency drives the subject to constitute himself by subjugating his objects, striving to rob them of their otherness. A plurality of subject positions will be recognized in every analytic encounter. Psychoanalytic work can allow for a lasting change insofar as it modifies the equilibrium between diverse psychic trends. The multiplicity of the issues at stake in subjectivation allows us to integrate theoretical pluralism while encouraging us to reflect on the diversification of our practices.     

Acquisition of social referencing via discrimination training in infants

This experiment investigated social referencing as a form of discriminative learning in which maternal facial expressions signaled the consequences of the infant's behavior in an ambiguous context. Eleven 4- and 5-month-old infants and their mothers participated in a discrimination-training procedure using an ABAB design. Different consequences followed infants' reaching toward an unfamiliar object depending on the particular maternal facial expression. During the training phases, a joyful facial expression signaled positive reinforcement for the infant reaching for an ambiguous object, whereas a fearful expression signaled aversive stimulation for the same response. Baseline and extinction conditions were implemented as controls. Mothers' expressions acquired control over infants' approach behavior for all participants. All participants ceased to show discriminated responding during the extinction phase. The results suggest that 4- and 5-month-old infants can learn social referencing via discrimination training.     

The Influence of Individual Attitudes on Construction of an Attitude Scale

Summary

The importance of talkativeness or the relative frequency of contributing to task interaction was examined as a factor which determines person perception. Both the quality and frequency of comments made in a two-person interaction were controlled by using experimental confederates who performed prescribed roles. Quantity but not quality of task contributions was significantly related to the attribution of creativity, and influence over others.     

The relationship of positive and negative expressiveness to the processing of emotion information

The tendency to express emotions non-verbally is positively related to perception of emotions in oneself. This study examined its relationship to perception of emotions in others. In 40 healthy adults, EEG theta synchronization was used to indicate emotion processing following presentation of happy, angry, and neutral faces. Both positive and negative expressiveness were associated with higher emotional sensitivity, as shown by cortical responses to facial expressions during the early, unconscious processing stage. At the late, conscious processing stage, positive expressiveness was associated with higher sensitivity to happy faces but lower sensitivity to angry faces. Thus, positive expressiveness predisposes people to allocate fewer attentional resources for conscious perception of angry faces. In contrast, negative expressiveness was consistently associated with higher sensitivity. The effects of positive expressiveness occurred in cortical areas that deal with emotions, but the effects of negative expressiveness occurred in areas engaged in self-referential processes in the context of social relationships.     

Implicit need for affiliation is associated with increased corrugator activity in a non-positive, but not in a positive social interaction

Affective changes in response to motive-relevant stimuli are a defining feature of implicit motives. We therefore expected to find an effect of individual differences in the implicit need for affiliation (nAff) on corrugator supercilii activity, an indicator of affect, when participants were confronted with nonverbal indicators of a conversational partner’s withdrawal. Participants’ nAff was assessed with a Picture Story Exercise (PSE). They were then involved in an interaction with a smiling or a neutral experimenter while their corrugator activity was measured with electromyography (EMG). As expected, we found higher corrugator activity for people high in nAff compared to people low in nAff when the experimenter kept a neutral facial expression throughout the interaction but not when he/she was smiling.
