Neural correlates of intertemporal choice in aggressive behavior

People often have to make decisions between immediate rewards and more long-term goals. Such intertemporal judgments are often investigated in the context of monetary choice or drug use, yet not in regard to aggressive behavior. We combined a novel intertemporal aggression paradigm with functional neuroimaging to examine the role of temporal delay in aggressive behavior and the neural correlates thereof. Sixty-one participants (aged 18–22 years; 37 females) exhibited substantial variability in the extent to which they selected immediate acts of lesser aggression versus delayed acts of greater aggression against a same-sex opponent. Choosing delayed-yet-more-severe aggression was increased by provocation and associated with greater self-control. Preferences for delayed aggression were associated with greater activity in the ventromedial prefrontal cortex (VMPFC) during such choices, and reduced functional connectivity between the VMPFC and brain regions implicated in motor impulsivity. Preferences for immediate aggression were associated with reduced functional connectivity between the VMPFC and the frontoparietal control network. Dispositionally aggressive participants exhibited reduced VMPFC activity, which partially explained and suppressed their preferences for delayed aggression. Blunted VMPFC activity may thus be a neural mechanism that promotes reactive aggression towards provocateurs among dispositionally aggressive individuals. These findings demonstrate the utility of an intertemporal framework for investigating aggression and provide further evidence for the similar underlying neurobiology between aggression and other rewarding behaviors.     

Socio-economic status and the developing brain in adolescence: A systematic review

Socioeconomic status is associated with differences in social, cognitive, and behavioral outcomes for adolescents. Correspondingly, the period reflects continued dynamic, complex, and adaptive brain development. Research demonstrates associations between the developing adolescent brain and SES; however, such research has not been systematically integrated. We undertook a systematic search of studies and review 21 papers that examined both SES and brain development or functioning as measured during adolescence or young adulthood in nonclinical populations (13–25 years old). Few studies focused on architecture and such findings were varied. The majority of studies focused on functioning with two themes emerging. First, studies demonstrate different activation in regions of interest to cognitive and behavioral tasks relative to SES. Second, when similar neurological activation is evident, they can be related to different behavioral observations relative to SES. There is also evidence of different neurological functioning associated with SES with regard to different conceptualizations and coding of SES. Further, some of the reviewed studies identified potential mediators to the relationship, such as parenting practices, stress, and IQ. Overall, the findings suggest it is important to consider SES and neighborhood context within neuroscience research and practice.     

Do Questions Get Infants Talking? Infant Vocal Responses to Questions and Declaratives in Maternal Speech

Maternal questions play a crucial role in early language acquisition by virtue of their special grammatical, prosodic and lexical forms, and their abundance in the input. Infants are able to discriminate questions from other sentence types and produce rising intonations in their own requests. This study examined whether caregiver questions were related to the quantity of infant vocalizations. Thirty‐six infants aged 10 and 14 months participated in a laboratory play session with their mothers. In separate blocks, mothers were instructed to ask questions and to refrain from asking questions. Both block‐level and utterance‐level analyses found no evidence that maternal questions affected the amount of infant‐response vocalizations. Mothers of 14‐month‐olds (but not 10‐month‐olds) tended to repeat questions. Copyright © 2016 John Wiley & Sons, Ltd.     

The effects of colour and valence on news evaluation

Research across different fields of psychology has reported effects of colour cues on a variety of cognitive processes. Especially, the colour red has been shown to have striking influences. In the context of media reception, however, colour effects have been widely neglected so far. This study made a first step in this direction by investigating the effects of the colour red (compared with blue and grey) on the way news articles are evaluated. Two types of news were framed by a coloured border while the valence of the news content additionally varied. Based on 369 participants who read and evaluated the news articles online, we observed effects for colour cues and news valence in the absence of an interaction effect, indicating that the colour red induced approach motivation. However, only the contrast between red and grey reached statistical significance, indicating that chromatic and achromatic colours may differ in their perceived visual saliency. Overall, these results provide an important complement to previous studies and have practical implications for media researchers and producers.     

Clergy Burnout: A Comparison Study with Other Helping Professions

Clergy experience a large number of stressors in their work, including role overload and emotional labor. Although studies have found high rates of depression in clergy, the degree of work-related burnout in clergy compared to other occupations is unknown. The widely used Maslach Burnout Inventory (MBI) measures three aspects of burnout: emotional exhaustion, depersonalization, and personal accomplishment. We sought studies using comparable versions of the MBI for clergy; for social workers, counselors, and teachers because of those occupations’ emotional intensity and labor; and for police and emergency personnel because of the unpredictability and stress-related physiological arousal in those occupations. We found a total of 84 studies and compared the ranges of burnout scores between the studies of clergy, each additional occupation, and MBI published mean norms. Compared to U.S. norms, clergy exhibited moderate rates of burnout. Across the three kinds of burnout, clergy scores were relatively better than those of police and emergency personnel, similar to those of social workers and teachers, and worse than those of counselors. Clergy may benefit from burnout prevention strategies used by counselors. The moderate levels of burnout found for clergy, despite the numerous stressors associated with their occupation, suggest that clergy generally cope well and may be models to study. Overall, there is room for improvement in burnout for all professions, especially police and emergency personnel. It is important to remember the variation within any profession, including clergy, and prevent and address burnout for those in need.     

The Effects of Alcohol Intoxication on Accuracy and the Confidence–Accuracy Relationship in Photographic Simultaneous Line‐ups

Acute alcohol intoxication during encoding can impair subsequent identification accuracy, but results across studies have been inconsistent, with studies often finding no effect. Little is also known about how alcohol intoxication affects the identification confidence–accuracy relationship. We randomly assigned women (N = 153) to consume alcohol (dosed to achieve a 0.08% blood alcohol content) or tonic water, controlling for alcohol expectancy. Women then participated in an interactive hypothetical sexual assault scenario and, 24 hours or 7 days later, attempted to identify the assailant from a perpetrator present or a perpetrator absent simultaneous line‐up and reported their decision confidence. Overall, levels of identification accuracy were similar across the alcohol and tonic water groups. However, women who had consumed tonic water as opposed to alcohol identified the assailant with higher confidence on average. Further, calibration analyses suggested that confidence is predictive of accuracy regardless of alcohol consumption. The theoretical and applied implications of our results are discussed.© 2017 The Authors Applied Cognitive Psychology Published by John Wiley & Sons Ltd.     

Minority Stress and the Risk of Unwanted Sexual Experiences in LGBQ Undergraduates

Sexual assault is prevalent among lesbian, gay, bisexual, and queer (LGBQ) college students, but its relationship to anti-LGBQ stigma has not been established. The goal of the present study was to determine whether minority stress, specifically internalized homophobia, predicted unwanted sexual experiences among LGBQ undergraduates (N = 763), whether routine behaviors (number of consensual sexual partners and alcohol use) mediated this relationship, and whether sense of LGBTQ community was a protective factor. Significant proportions of sexual minority men (10 %), women (18 %), and non-binary or transitioning students (19 %) reported an unwanted sexual experience since entering college. Internalized homophobia was associated with greater risk of unwanted sexual experiences. It also had a negative indirect effect on unwanted sexual experience risk through a negative association with number of sexual partners. Alcohol use did not mediate the relationship between internalized homophobia and unwanted sexual experiences. Sense of LGBTQ community was associated with lower risk, mediated by lower levels of internalized homophobia. The relationships between internalized homophobia and unwanted sexual experience risk were similar for women and men. These findings demonstrate that minority stress increases LGBQ students’ risk of sexual victimization and that in-group social relationships can mitigate this risk. We argue that minority stress is an important risk factor for sexual violence. Violence prevention interventions should attempt to reduce internalized homophobia, and colleges and high schools should establish LGBQ-affirming social climates and provide resources for LGBQ students, including targeted violence prevention efforts and programs that foster a sense of supportive community.     

Reclaiming a Mind: Commentary on Paper by Yvette Esprey

In exploring the problem of thinking in black and white we encounter the difficulty of maintaining our subjectivity as good racialized whites. This commentary follows the journey that Yvette Esprey takes us on to reclaim her thinking mind and reconstruct an authentic racialized self. In addition, this work expands on the concept of racism as a form of abjection in which the hated parts of self that are extruded paradoxically come to construct the self.
