High Behavioral Approach System (BAS) sensitivity, reward responsiveness, and goal-striving predict first onset of bipolar spectrum disorders: a prospective behavioral high-risk design

A prospective, behavioral high-risk design provided a theoretically guided examination of vulnerability to first onset of bipolar spectrum disorder based on the Behavioral Approach System (BAS) model. Adolescents (ages 14-19) at an "age of risk" for bipolar disorder onset were screened on BAS sensitivity by interviewers blind to current symptoms, lifetime history, and family history of psychopathology. Participants were selected with high versus moderate levels of BAS sensitivity and administered a lifetime diagnostic interview. Those with a bipolar spectrum disorder, psychosis, or hypomanic episode with onset prior to the BAS sensitivity assessment were excluded. High BAS (n = 171) and moderate BAS (n = 119) sensitivity participants in the final sample completed baseline measures of symptoms, goal-setting, and reward responsiveness and were followed prospectively with semistructured diagnostic interviews every 6 months. Consistent with the vulnerability hypothesis of the BAS model of bipolar disorder, high BAS participants had a greater likelihood, and shorter time to onset, of bipolar spectrum disorder than moderate BAS participants across an average of 12.8 months of follow-up (12.9% vs. 4.2%), controlling for baseline depressive and hypomanic symptoms, and family history of bipolar disorder. High reward responsiveness on a behavioral task and ambitious goal-striving for popular fame and financial success (but not impulsivity) also predicted first onset of bipolar spectrum disorder controlling for the covariates and BAS risk group, and ambitious goal-striving partially mediated the BAS risk group effect. We discuss implications of the findings for the BAS model of bipolar disorder and early intervention efforts.     

Different attentional blink tasks reflect distinct information processing limitations: an individual differences approach

To study the temporal dynamics and capacity-limits of attentional selection and encoding, researchers often employ the attentional blink (AB) phenomenon: subjects' impaired ability to report the second of two targets in a rapid serial visual presentation (RSVP) stream that appear within 200-500 ms of one another. The AB has now been the subject of hundreds of scientific investigations, and a variety of different dual-target RSVP paradigms have been employed to study this failure of consciousness. The three most common are those where targets are defined categorically from distractors; those where target definition is based on featural information; and those where there is a set switch between T1 and T2, with the first target typically being featurally defined and T2 requiring a detection or discrimination judgment (probe task). An almost universally held assumption across all AB theories is that these three tasks measure the same deficit; however here, using an individual differences approach, we demonstrate that AB magnitude is only related across categorical and featural tasks. Thus, these paradigms appear to reflect a distinct cognitive limitation from that observed under set-switch conditions.     

Resisting temptation of unhealthy food: interaction between temptation-elicited goal activation and self-control

Counteractive control theory suggests that the cognitive accessibility of a goal in response to a temptation cue predicts self-regulation of behaviour consistent with that goal. The current study provided a novel test of this effect in the eating domain, exploring the moderating role of trait self-control. A sample of 124 women (18–25 years) completed a lexical decision task to assess cognitive accessibility of the weight-management goal after food temptation priming. Eating self-regulation was operationalised as unhealthy snack food intake measured in a task disguised as a taste-test. Participants completed trait self-control and temptation experience intensity measures. Cognitive accessibility predicted lower food intake, but only among high self-control participants. The relationship was mediated by temptation experience intensity: participants with high cognitive accessibility felt less tempted, and subsequently ate less food. Results suggest that changing the processes underlying the temptation experience, rather than the cognitive accessibility of a goal may more effectively enhance self-regulation among low self-control individuals.     

Recognition-induced forgetting does not occur for temporally grouped objects unless they are semantically related

Recent evidence has shown that practice recognizing certain objects hurts memories of objects from the same category, a phenomenon called recognition-induced forgetting. In all previous studies of this effect, the objects have been related by semantic category (e.g., instances of vases). However, the relationship between objects in many real-world visual situations stresses temporal grouping rather than semantic relations (e.g., a weapon and getaway car at a crime scene), and temporal grouping is thought to cluster items in models of long-term memory. The goal of the present study was to determine whether temporally grouped objects suffer recognition-induced forgetting. To this end, we implemented a modified recognition-induced forgetting paradigm in which the objects were temporally clustered at study. Across four experiments, we found that recognition-induced forgetting occurred only when the temporally clustered objects were also semantically related. We conclude by discussing how these findings relate to real-world vision and inform models of memory.     

Reduce temptation or resist it? Experienced temptation mediates the relationship between implicit evaluations of unhealthy snack foods and subsequent intake

A more negative implicit evaluation of unhealthy food stimuli and a more positive implicit evaluation of a weight-management goal have been shown to predict lower consumption of unhealthy food. However, the associations between these evaluations, temptation to indulge and consumption of unhealthy food remain unclear. The current study investigated whether temptation would mediate the relationship between implicit food and goal evaluations and consumption (resembling an antecedent-focused route to self-control of eating), or whether those evaluations would moderate the relationship between temptation and consumption (resembling a response-focused route). A sample of 156 women (17–25 years), who tried to manage their weight through healthy eating, completed two implicit association tasks assessing implicit food and goal evaluations, respectively. Intake of four energy-dense snack foods was measured in a task disguised as a taste test, and participants reported the strength of experienced temptation to indulge in the snacks offered. Negative implicit food evaluation was associated with lower snack intake, and temptation mediated this relationship. Implicit goal evaluation was unrelated to both temptation strength and snack consumption. The findings contribute to an understanding of how negative implicit unhealthy food evaluation relates to lower consumption, namely through the mediation of temptation to indulge in those foods.     

Recognition Practice Results in a Generalizable Skill in Older Adults: Decreased Intrusion Errors to Novel Objects Belonging to Practiced Categories

Accessing memories is often accompanied by both positive and negative consequences. For example, practice recognizing some visual images held in memory can improve memory for the practiced images and hurt memory for related images (i.e., recognition‐induced forgetting). However, visual stimuli have been shown to improve memory for older adults by decreasing false memories. This suggests that older adults may be immune to recognition‐induced forgetting and that recognition practice may decrease susceptibility to intrusion errors. We first tested the hypothesis that older adults are immune to recognition‐induced forgetting. We found older adults exhibit recognition‐induced forgetting. Next, we tested the hypothesis that recognition practice decreases older adult's rates of intrusion errors. We found lower intrusion errors for novel objects from practiced categories. This represents a generalizable learning effect; practice recognizing a target object (e.g., your pill bottle) improves the rejection of new lures (e.g., identifying the pill bottle that is not yours).Copyright © 2016 John Wiley & Sons, Ltd.     

Protocols for the Investigation of Information Processing in Human Assessment of Fundamental Movement Skills

Fundamental movement skill (FMS) assessment remains an important tool in classifying individuals’ level of FMS proficiency. The collection of FMS performances for assessment and monitoring has remained unchanged over the last few decades, but new motion capture technologies offer opportunities to automate this process. To achieve this, a greater understanding of the human process of movement skill assessment is required. The authors present the rationale and protocols of a project in which they aim to investigate the visual search patterns and information extraction employed by human assessors during FMS assessment, as well as the implementation of the Kinect system for FMS capture.     

The consequences of intergroup ideologies and prejudice control for discrimination and harmony

In the present study, we investigated two literature bases by way of a community survey across Australia. We investigated four acculturation orientations (assimilation, multiculturalism, color‐blind, and polyculturalism ideologies) and the motivations to respond without prejudice. We examined what predicted support for Harmony Day as well as explicit discrimination. Multiculturalism, polyculturalism, and internal motivation to respond without prejudice correlated with positive attitudes in both scenarios. External motivation to respond without prejudice was positively correlated with discrimination. Conversely, color‐blind ideology had no effect, and assimilation ideology related positively to explicit discrimination and negatively with Harmony Day. Using a multiple regression analysis, there was a difference in emphasis in different contexts. Our findings provide antiprejudice practitioners with material for discussions which can promote positive intergroup relations.     

They’re (not) playing our song: (Ir)religious identity moderates the effects of listening to religious music on memory,self-esteem,and mood

Previous research suggests that listening to music can enhance memory and well-being. However, what is often missing from this analysis is consideration of the social dimensions of music—for example, its capacity to affirm or threaten listeners’ social identities. This study examined whether (ir)religious music that was potentially identity-affirming or identity-threatening (Christian hymns, Buddhist chants, classical, or no music) would affect Christians’ and Atheists’ (N = 267) well-being and memory performance while listening. Analyses revealed significant interactions between (ir)religious group and music type on memory, self-esteem, and mood. Listening to music that potentially threatened one's religious identity appeared to undermine both performance self-esteem and actual memory performance, while increasing feelings of hostility. This pattern was found for Christians (vs. Atheists) who listened to Buddhist chants. Conversely, Atheists’ performance self-esteem (and to some degree their memory performance) was lowest, and their hostility highest, when they listened to Christian hymns. In this way, listening to music that potentially threatened one's religious group identity (or lack thereof) appeared to be detrimental for memory, self-esteem, and mood. These results bridge research on the psychology of religion, music psychology, and social identity theorizing by demonstrating that the effects of music on memory and well-being may reflect important (even sacred) social identities, with potential implications for individual well-being and intergroup relations.     

Avoiding affect in intergroup relations: The roles of dispositional and intergroup empathy in the relationship between alexithymia and prejudice

Alexithymia, that is, difficulties in recognizing, communicating, and processing one's own emotions, is associated with poorer interpersonal relations. Emotional processes are key drivers and mechanisms of prejudice and its reduction, and alexithymia is thought to influence individuals' empathic responses. This research examined the relationship between alexithymia and prejudice, and the role of empathy in this relationship. Three studies were conducted in three intergroup contexts to test whether alexithymia is also associated with poorer intergroup relations with lesbian, gay, bisexual, and transgender+ individuals (Study 1, N = 126 heterosexual late adolescents) and Asian British people (Study 3, N = 300 White adults) in the United Kingdom, and immigrants in Italy (Study 2, N = 381 Italian adults). Participants completed the Toronto Alexithymia Scale (TAS-20), measures on dispositional and intergroup empathic concern (EC) and perspective taking (PT) as well as measures of prejudice (anti-outgroup hostility, anti-outgroup attitudes, and anti-outgroup behavioral intentions). Lower dispositional EC (Studies 1, marginal effect in Study 2) and intergroup EC and PT (Study 3) mediated the relationship between the Externally Oriented Thinking subscale of the TAS-20 (i.e., avoiding emotions and affective thinking) and greater prejudice. The findings are important for understanding the challenges of late adolescents and adults with alexithymia in intergroup relations, highlighting the role of dispositional and intergroup empathy for individual differences such as alexithymia in endorsing prejudice.
