Clarifying the Relationship Between Ostracism and Relational Devaluation

We examine how three perspectives on relational devaluation relate to needs threat following ostracism. In two experiments with 179 first-year psychology students, distress was greatest when participants were ostracized without any prior throws, and distress decreased linearly with increasing prior inclusion. In Experiment 3, using 76 first-year psychology students, we manipulated expectations of exclusion and found expectations predicted distress following ostracism, suggesting ostracism's distress can be influenced by norm-based expectations of inclusion, and that progressive relational devaluation is not a necessary condition for ostracism's distress.     

Children's and adults’ understanding of the “disgust face”

By the age of 4 years, children (N=120) know the meaning of the word disgust as well as they know the meaning of anger and fear; for example, when asked, they are equally able to generate a plausible cause for each of these emotions. Yet, in tasks involving facial expressions (free labelling of faces, deciding whether or not a face expresses disgust, or finding a “disgust face” in an array of faces), a majority of 3- to 7-year-old children (N=144) associated the prototypical “disgust face” with anger and denied its association with disgust (25% of adults on the same tasks did so as well). These results challenge the assumption that all humans easily recognise disgust from its facial expression and that this recognition is a precursor to children's understanding of the emotion of disgust.     

Introducing the sick face

Research on disgust in neuroscience, medicine, and psychology often relies on a disgust facial expression from a standardized set. Two studies (N = 60 and N = 160) compared this standard disgust face to a new facial expression called the “sick face” posed by three different actors asked to look as if they were sick and about to vomit. Relative to the standard disgust face, the sick face was significantly more likely to be endorsed as disgust, less likely to be endorsed as another emotion, and rated as conveying disgust more intensely. Disgust may not have a facial signal, but various faces may serve as cues to disgust.     

Application of social identity theory in group therapy with stigmatized adults.

Social identity theory was applied in group therapy for adults with mild mental retardation. Social identity theory suggests that social group membership, also called collective identity, has an impact on self-esteem. Individuals will try to maintain self-esteem by viewing their social groups positively. This may not be possible for individuals who are members of a stigmatized group. However, it may be possible to enhance self-esteem by broadening one's awareness of collective identity. Furthermore, being able to positively view other individuals who are co-members of one's own stigmatized group can also have positive consequences for self-esteem. A clinical vignette demonstrates this process in group therapy. Results are discussed as being applicable to members of various stigmatized groups.     

Message size constraints on discourse planning in synchronous computer-mediated communication

Three groups of 20 dyads planned the MTV Music Video Awards Show over computers. The groups varied in whether they could send 4-line, 10-line, or 18-line messages, in part to examine whether increased planning efficiency in computer-mediated communication reflects communication strategies associated with constraints on message size. The results demonstrate that increased efficiency is not a function of such design features as the maximum message that may be sent. However, the subjects in the 4-line condition sent shorter messages to one another, were less likely to engage in a strategy of making multiple suggestions that required a single assent, and were more likely to differ in the relative proportion of their contributions to the discourse. The subjects in the 10-line condition had shorter maximum messages (and proportionately more disfluencies) than did those in the 18-line condition, despite the finding that the maximum messages of the latter would have also fit within 10 lines. Thus, the results also support a claim that size of the text window may result in different discourse management strategies and may influence an initial discourse-planning stage.     

(Emotion-centered) problem-solving therapy: An update

Problem-solving therapy (PST) is a psychosocial intervention, typically considered to be a member of the cognitive and behaviour therapies family, and is based on a biopsychosocial, diathesis-stress model of psychopathology. The overarching goal of this approach is to promote the successful adoption of adaptive problem-solving attitudes and the effective implementation of certain behaviours as a means of coping with life stressors in order to attenuate the negative effects of such events on physical and mental well-being. Over the past several decades, in addition to accumulating strong support for its efficacy as a clinical intervention, similar to many other forms of psychotherapy, PST has undergone various evolutionary changes. Developed primarily as a more cognitive-based approach, due to the large body of literature in the field of affective neuroscience that underscores the importance of the impact of affect on problem solving, PST has evolved into emotion-centered problem-solving therapy (EC-PST). This article provides for a brief excursion into the historical roots of PST and why it has evolved into EC-PST, as well as providing support for its characterisation as a transdiagnostic approach. In addition, several meta-analyses that underscore its efficacy are described, as well as the most recent clinical guidelines that comprise EC-PST.     

A behavior-based circuit model of how outcome expectations organize learned behavior in larval Drosophila

Drosophila larvae combine a numerically simple brain, a correspondingly moderate behavioral complexity, and the availability of a rich toolbox for transgenic manipulation. This makes them attractive as a study case when trying to achieve a circuit-level understanding of behavior organization. From a series of behavioral experiments, we suggest a circuitry of chemosensory processing, odor-tastant memory trace formation, and the "decision" process to behaviorally express these memory traces--or not. The model incorporates statements about the neuronal organization of innate vs. conditioned chemosensory behavior, and the types of interaction between olfactory and gustatory pathways during the establishment as well as the behavioral expression of odor-tastant memory traces. It in particular suggests that innate olfactory behavior is responsive in nature, whereas conditioned olfactory behavior is captured better when seen as an action in pursuit of its outcome. It incorporates the available neuroanatomical and behavioral data and thus should be useful as scaffold for the ongoing investigations of the chemo-behavioral system in larval Drosophila.
