The disguise of sobriety: unveiled by alcohol in persons with an aggressive personality

This investigation examined the factor structure of 8 well-validated self-report measures that assess traits that fall under the rubric of an "aggressive personality" and then determined how those factor(s) moderated the association between alcohol intoxication and aggression. Participants were 518 (252 men and 266 women) healthy social drinkers between 21 and 35 years of age. Following the consumption of an alcoholic or a placebo beverage, participants were tested on a laboratory aggression paradigm in which electric shocks were received from, and administered to, a fictitious opponent. Aggression was operationalized as the shock intensities and durations administered to the opponent. Results demonstrated a unidimensional factor structure for the aggressive personality traits, which were then combined into a latent variable. The aggressive personality variable moderated the alcohol-aggression relation. Specifically, alcohol was significantly more likely to increase aggression in persons with higher, compared with lower, aggressive personality scores.     

Personality Trait Development and Social Investment in Work

A longitudinal study of employed individuals was used to test the relationship between social investment at work—the act of cognitively and emotionally committing to one’s job—and longitudinal and cross-sectional personality trait development. Participants provided ratings of personality traits and social investment at work at two time-points, separated by approximately 3 years. Data were analyzed using latent change models. Cross-sectional results showed that extraversion, agreeableness, conscientiousness, and emotional stability were related to social investment at work. Additionally, a positive association was found between longitudinal change in social investment in work and change in personality traits—especially conscientiousness. Finally, the correlated changes in social investment and personality traits were invariant across age groups, suggesting that personality traits remain malleable across the lifespan.     

No atheists in foxholes: arguments for (but not against) afterlife belief buffers mortality salience effects for atheists

Terror management theory (TMT) posits that people cope with mortality concerns via symbolic immortality (e.g., secular cultural beliefs that outlast death) and/or literal immortality (afterlife belief). However, what happens when these two forms of immortality conflict, as in atheism? Would atheists' mortality concerns be better assuaged by affirming an afterlife, or by affirming their literal immortality-denying worldview? Drawing on an untested TMT hypothesis, we predicted that atheists would be buffered from mortality concerns if their atheistic worldview - no life after death - was challenged, but not if it was supported. Results confirmed the hypothesis and were also found for theists and agnostics. These findings support TMT's claim that literal immortality is of paramount importance in ameliorating death concerns.     

A processing approach to the working memory/long-term memory distinction: evidence from the levels-of-processing span task

Recent theories suggest that performance on working memory (WM) tasks involves retrieval from long-term memory (LTM). To examine whether WM and LTM tests have common principles, Craik and Tulving's (1975) levels-of-processing paradigm, which is known to affect LTM, was administered as a WM task: Participants made uppercase, rhyme, or category-membership judgments about words, and immediate recall of the words was required after every 3 or 8 processing judgments. In Experiment 1, immediate recall did not demonstrate a levels-of-processing effect, but a subsequent LTM test (delayed recognition) of the same words did show a benefit of deeper processing. Experiment 2 showed that surprise immediate recall of 8-item lists did demonstrate a levels-of-processing effect, however. A processing account of the conditions in which levels-of-processing effects are and are not found in WM tasks was advanced, suggesting that the extent to which levels-of-processing effects are similar between WM and LTM tests largely depends on the amount of disruption to active maintenance processes.     

SCIENCE AND TRANSCENDENCE: WESTPHAL,DERRIDA, AND RESPONSIBILITY

Abstract. On the naive reading, “radical social constructivism” would be the result of “deconstructing” science. Science would simply be a contingent construction in accordance with social determinants. However, postmodernism does not necessarily abandon fidelity to the objects of thought. Merold Westphal's Derridean philosophy of religion emphasizes that even theology need not eliminate the transcendence of the divine other. By drawing an analogy between natural and supernatural transcendence, I argue that science is similarly called to responsibility in the encounter with that which lies outside its horizon of expectation. Science's rational autonomy is overcome by the heteronomy of realities that precede it. Understanding species as homeostatic property clusters is an example of nonessentialist, postmodern, and scientific realism. Science is still a vehicle for encountering natural alterity, thus decentering the relativism thought to characterize postmodernism. However, natural science must not attempt to place the whole of being at human disposal if it is to fulfill the potential of Westphal's philosophy of religion.     

Are the symptoms of cannabis use disorder best accounted for by dimensional, categorical, or factor mixture models? A comparison of male and female young adults

Despite the consensus that criteria for cannabis abuse and dependence and symptoms of withdrawal are best explained by a single latent liability, it remains unknown whether alternative models provide a better explanation of these criteria. A series of latent factor, latent class, and hybrid factor mixture models were fitted to data from 872 recent cannabis users from the Minnesota Twin Family Study who completed Diagnostic and Statistical Manual of Mental Disorders (3rd ed., revised, and 4th ed.) diagnostic criteria for cannabis abuse, dependence, and symptoms of withdrawal. Despite theoretical appeal, results did not support latent class or factor mixture modeling. Instead, symptoms of abuse, dependence, and withdrawal were better summarized by a single latent factor Cannabis Use Disorder (CUD) for male and female young adults. An almost 2-fold sex difference in item endorsement was best explained by a single mean difference on the CUD factor, indicating that young men have a greater latent liability toward expressing CUD.     

Exploring the Impact of Attachment Anxiety and Avoidance on the Perception of Couple Conflict

Attachment anxiety and avoidance have been shown to affect how an individual processes social information such as facial expressions. Previous work has not explored perception of couple relationships. The current study had 39 individuals observe images and videos of couples in conflict. Results suggest that individuals with higher attachment anxiety perceived more intensity in negative interactions/affect and less positive interactions/affect in the couples they observed. Implications for therapy, clinical supervision, and family life education are discussed.     

Too dog tired to avoid danger: Self-control depletion in canines increases behavioral approach toward an aggressive threat

This study investigated whether initial self-control exertion by dogs would affect behavioral approach toward an aggressive threat. Dogs were initially required to exert self-control (sit still for 10 min) or not (caged for 10 min) before they were walked into a room in which a barking, growling dog was caged. Subject dogs spent 4 min in this room but were free to choose where in the room they spent their time. Approaching the unfamiliar conspecific was the predisposed response, but it was also the riskier choice (Lindsay, 2005). We found that following the exertion of self-control (in comparison with the control condition), dogs spent greater time in proximity to the aggressor. This pattern of behavior suggests that initial self-control exertion results in riskier and more impulsive decision making by dogs.     

Can a modified lineup procedure improve the usefulness of confidence?

In a face recognition, mini-lineup experiment we examined two aspects of the use of confidence about lineups. We modified the lineup procedure attempting to eliminate the difference in confidence–accuracy relationship between positive (old or identification) and negative (new or not present) decisions. In the modified procedure, participants: (1) selected the lineup member that best matched their memory of the target; (2) rated their confidence that the best match was indeed the target; and (3) indicated (yes/no) whether the best match was the target. Although the modified procedure produced higher accuracy than a standard simultaneous procedure, there was no evidence that it affected the confidence–accuracy relationship. Additionally, the modified procedure also allowed us to compare the extent to which confidence ratings versus binary recognition decisions better discriminated studied from unstudied faces. The results revealed a clear advantage for confidence, but indicated that binary responses were also a unique predictor.
