Putting feelings into words: affect labeling disrupts amygdala activity in response to affective stimuli

Putting feelings into words (affect labeling) has long been thought to help manage negative emotional experiences; however, the mechanisms by which affect labeling produces this benefit remain largely unknown. Recent neuroimaging studies suggest a possible neurocognitive pathway for this process, but methodological limitations of previous studies have prevented strong inferences from being drawn. A functional magnetic resonance imaging study of affect labeling was conducted to remedy these limitations. The results indicated that affect labeling, relative to other forms of encoding, diminished the response of the amygdala and other limbic regions to negative emotional images. Additionally, affect labeling produced increased activity in a single brain region, right ventrolateral prefrontal cortex (RVLPFC). Finally, RVLPFC and amygdala activity during affect labeling were inversely correlated, a relationship that was mediated by activity in medial prefrontal cortex (MPFC). These results suggest that affect labeling may diminish emotional reactivity along a pathway from RVLPFC to MPFC to the amygdala.     

Prevalence of Psychiatric Disorders Among Children of Different Ethnic Origin

The present study assesses the population prevalence of DSM-IV disorders among native and immigrant children living in low socio-economic status (SES) inner-city neighborhoods in the Netherlands. In the first phase of a two-phase epidemiological design, teachers screened an ethnically diverse sample of 2041 children aged 6–10 years using the Strengths and Difficulties Questionnaire (SDQ). In the second phase, a subsample of 253 children was psychiatrically examined, while their parents were interviewed. In addition, teachers completed a short questionnaire about 10 DSM-IV items. Prevalence was estimated using the best-estimate diagnosis based on parent, child and teacher information. Projected to the total population, 11% of the children had one or more impairing psychiatric disorders, which did not differ between native and non-native children. In the total group a clear relationship was observed between the prevalence of psychiatric disorders and gender, parental psychopathology, peer problems and school problems, but not among all ethnic groups separately. This study suggests that the prevalence of psychiatric disorders among non-treated minority and native children in low SES inner-city neighborhoods does not materially differ. However, associated mechanisms may be influenced by ethnicity.     

The effects of trust in authority and procedural fairness on cooperation

The present research examined the effect of procedural fairness and trust in an authority on people's willingness to cooperate with the authority across a wide range of social situations. Prior research has shown that the presence of information about whether an authority can be trusted moderates the effect of procedural fairness. If no trust information is available, procedural fairness influences people's reactions. This is not the case when information about the trustworthiness of the authority is present. In the present article, it is argued that information about whether the authority can or cannot be trusted may also moderate the effect of procedural fairness in predicting levels of cooperation. Assuming that the use of fair procedures by authorities that cannot be trusted is less influential than is the enactment of procedures by trustworthy authorities, it is predicted that trust in authority moderates the influence of procedural fairness on cooperation in such a way that procedural fairness has a positive effect on cooperation primarily when trust in authority is high. Results from 4 studies (2 experimental studies and 2 field studies) provide supportive evidence for this interaction.     

Effort during visual search and counting: insights from pupillometry

We investigated the processing effort during visual search and counting tasks using a pupil dilation measure. Search difficulty was manipulated by varying the number of distractors as well as the heterogeneity of the distractors. More difficult visual search resulted in more pupil dilation than did less difficult search. These results confirm a link between effort and increased pupil dilation. The pupil dilated more during the counting task than during target-absent search, even though the displays were identical, and the two tasks were matched for reaction time. The moment-to-moment dilation pattern during search suggests little effort in the early stages, but increasingly more effort towards response, whereas the counting task involved an increased initial effort, which was sustained throughout the trial. These patterns can be interpreted in terms of the differential memory load for item locations in each task. In an additional experiment, increasing the spatial memory requirements of the search evoked a corresponding increase in pupil dilation.These results support the view that search tasks involve some, but limited, memory for item locations, and the effort associated with this memory load increases during the trials. In contrast, counting involves a heavy locational memory component from the start.     

Defining body deception and its role in peer based social comparison theories of body dissatisfaction

The purpose of the current study was to operationalize the phenomenon of body deception, describe its theoretical importance, and validate its existence in an experimental paradigm. The definition of body deception includes the intentional misrepresentation of information about appearance to others. The present study examined body deception in a controlled experimental study of male and female same-sex peer groups using a series of hierarchical linear models. Ninety male and 90 female undergraduates were randomized to an experimental same-sex peer group or individual control condition. The results suggested that both men and women used body deception among peers, but men's body deception was muscularity driven whereas women's was thinness driven. Body dissatisfaction was significantly predictive of the degree of body deception used by both genders and it was significantly related to peer group membership. An integrated model for the role of body deception in body image disturbance is proposed.     

Piketty,Marxian Political Economy,and the Law of the Falling Rate of Profit

This article examines two views about the capitalism that lies at the heart of modern industrial society. We owe to Marx and Piketty two large‐scale, hugely important, but very different studies of the nature of modern industrial capitalism. In Capital, Marx provides a complex analysis of the anatomy of modern industrial capitalism, which he regards not as stable but rather as over time unstable and tending toward internal collapse on several grounds, of which the most important is apparently the so‐called tendency of the falling rate of profit. The falling rate of profit supposedly threatens its continued existence. Piketty criticizes the latter view in the context of his theory of contemporary capitalism. The article suggests, first, that Marx's view of the falling rate of interest is empirically implausible but Piketty's rival claim is empirically plausible. Second, a successful transition from capitalism to communism on Marxian grounds is unlikely in practice. And finally, despite Marx's intentions, it is unlikely to realize itself in practice, and is in this respect a traditional theory.     

Bending rules: the shape of the perceptual generalisation gradient is sensitive to inference rules

Generalising what is learned about one stimulus to other but perceptually related stimuli is a basic behavioural phenomenon. We evaluated whether a rule learning mechanism may serve to explain such generalisation. To this end, we assessed whether inference rules communicated through verbal instructions affect generalisation. Expectancy ratings, but not valence ratings, proved sensitive to this manipulation. In addition to revealing a role for inference rules in generalisation, our study has clinical implications as well. More specifically, we argue that targeting inference rules might prove to be an effective strategy to affect the excessive generalisation that is often observed in psychopathology.
