Wealth inequality and activism: Perceiving injustice galvanizes social change but perceptions depend on political ideologies

What motivates people to engage in activism against wealth inequality? The simple answer is perceiving injustice. However, the current work demonstrates that these perceptions depend on political ideologies. More specifically, for political liberals who frequently question the fairness of the economic system, messages simply describing the extent of the inequality (distributive injustice) are enough to motivate activism (Study 1). For political conservatives, who are inclined to believe that inequality results from fair procedures, messages must also detail how the system of economic forces is unjust (procedural injustice; Studies 2 and 3). Together, these studies suggest perceiving injustice can galvanize social change, but for conservatives, this means more than simply outlining the extent of the inequality.     

Increased parasympathetic activity and ability to generate positive emotion: The influence of the BDNF Val66Met polymorphism on emotion flexibility

Cross-species behavioral research suggests that a single nucleotide polymorphism (SNP) in the brain-derived neurotrophic factor (BDNF) gene (rs6265, Val66Met), influences behavioral inflexibility. This SNP has not yet been linked to variability in emotion-related behaviors, despite broader evidence suggesting an association may be present. This investigation explored the role of the BDNF Val66Met polymorphism in emotion response behaviors measured during a lab-based emotional provocation. Specifically, the influence of BDNF Val66Met in emotion flexibility was explored in a sample of healthy adults (N?=?120), emotion responses were recorded during the emotional provocation on multiple dimensions, in response to emotionally-evocative videos of negative then positive valence. These results suggest that Met carriers exhibit decreased parasympathetic responding, and reduced ability to generate positive emotion, relative to Val homozygotes. These findings are the first to suggest an association between the Met allele and a pattern of responding indicative of emotion inflexibility that might afford greater risk for psychopathology.     

The effects of list-method directed forgetting on recognition memory

University of Illinois at Urbana-Champaign, Urbana, Illinois It is an almost universally accepted claim that the list-method procedure of inducing directed forgetting does not affect recognition. However, previous studies have omitted a critical comparison in reaching this conclusion. This article reports evidence that recognition of material learnedafter cue presentation is superior for conditions in which the material that preceded cue presentation was designated as to-be-forgotten. Because the absence of an effect of directed-forgetting instructions on recognition is the linchpin of the theoretical claim that retrieval inhibition and not selective rehearsal underlies that effect, the present results call into question the need to postulate a role for inhibition in directed forgetting.     

Attentional fixation in panic disorder

According to Beck's (1988) clinical observations, patients with panic disorder describe a fixation on their distressing physical and psychological symptoms and an inability to access corrective information during panic attacks. The present study sought to evaluate empirically the notion that attentional fixation is characteristic of these patients. A subset of panic patients participating in 3 cognitive therapy clinical trials completed the Attentional Fixation Questionnaire (AFQ) at intake, during treatment and at termination. The AFQ had adequate internal consistency at all time intervals, and it correlated positively with measures of depression, anxiety and distorted cognitive content. At termination, the AFQ total score and nearly all single items decreased significantly, and patients who continued to meet diagnostic criteria for panic disorder scored higher on most items than patients who no longer met diagnostic criteria for panic disorder. These preliminary data suggest that attentional fixation is an important dimension of cognition relevant to panic disorder.     

The functions of nonsuicidal self-injury: support for cognitive-affective regulation and opponent processes from a novel psychophysiological paradigm

Although research on the reasons for engaging in nonsuicidal self-injury (NSSI) has increased dramatically in the last few years, there are still many aspects of this pernicious behavior that are not well understood. The purpose of this study was to address these gaps in the literature, with a particular focus on investigating whether NSSI (a) regulates affective valence in addition to affective arousal and (b) serves a cognitive regulation function in addition to an affect regulation function. To elucidate these issues, the present study utilized a sample of 112 participants (33 controls, 39 no pain controls, 16 NSSI individuals, and 24 controls matching the affect dysregulation levels of the NSSI group), employed psychophysiological measures of affective valence (startle-alone reactivity) and quality of information processing (prepulse inhibition), and used experimental methods involving an NSSI-proxy to model the NSSI process. Results largely were consistent with predictions, supporting the hypotheses that NSSI serves to regulate cognitive processing and affective valence. On this latter point, however, the control groups also showed a decrease in negative affective valence after the NSSI-proxy. This unexpected finding is consistent with the hypothesis that opponent processes may contribute to the development of self-injurious behaviors (Joiner, 2005). Overall, the present study represents an important extension of previous laboratory NSSI studies and provides a fertile foundation for future studies aimed at understanding why people engage in NSSI.
