Greed is good? Student disciplinary choice and self-reported psychopathy

The idea of the organisational psychopath has become not only popular in recent times, but increasingly relevant, thanks to the alleged role of high-profile members of the commercial sector in the global recession. To test the proposition that self-reported sub-clinical psychopathy might be disproportionately more common amongst those people electing to study commerce/business at University, 903 first-year students enrolled in a range of academic degrees completed a survey containing Levenson’s Self-Report Psychopathy Scale (Levenson, Kiehl, & Fitzpatrick, 1995) and Paulhus’ (1991) Balanced Inventory of Desirable Responding. Even after accounting for social desirability, commerce students reported higher levels of primary psychopathy than other students, regardless of sex.     

Self-Judgments of Accuracy as Indicators of Performance Evaluation Quality: Should We Believe Them?

Purpose  

This paper explores how well raters’ self-judgments of their rating and behavioral accuracy reflect reality. We also explore the role of motivation in determining the quality of raters’ self-judgments and their rating and behavioral accuracy.     

The Impossibility of Emergent Conscious Causal Powers

This paper argues that emergent conscious properties can't bestow emergent causal powers. It supports this conclusion by way of a dilemma. Necessarily, an (allegedly efficacious) emergent conscious property brings about its effects actively or other than actively (in senses explained in the paper). If actively, then, the paper argues, the emergent conscious property can't have causal powers at all. And if other than actively, then, the paper argues, the emergentist finds himself committed to incompatible accounts of causation.     

Psychometric evaluation of the Drive for Muscularity Scale in a community-based sample of Scottish men participating in an organized sporting event

As the drive for muscularity is an important construct for researchers involved in understanding men's body image, having reliable and valid measures of the construct is essential. This study assessed the Drive for Muscularity Scale (DMS) in a community-based sample of 594 Scottish men participating in an organized running event. Exploratory factor analysis revealed two subscales (Muscularity-oriented body image and Muscularity behavior) as well as a higher-order factor. Both subscales and the total score had acceptable levels of internal consistency, test–retest reliability, and construct validity. These findings provide support for the DMS as a measure of the drive for muscularity in men. It is recommended that, in future, careful consideration is given to the distinction between muscularity attitudes and behavior.     

Pharmacologic and Behavioral Withdrawal From Addictive Drugs

ABSTRACT— Recent theories suggest that drug withdrawal does not motivate drug use and relapse. However, data now show that withdrawal produces complex changes over time in at least two symptoms (i.e., negative affect and urges) that are highly predictive of relapse. Evidence suggests that falling levels of the drug in the blood and interruption of the drug self-administration ritual both affect these symptoms. Both of these forms of withdrawal motivate renewed drug use in addicted individuals.     

Sόnar Calling GJ273B: The Argumentative Issue of METI

Since active messaging to targeted extraterrestrial bodies is an ongoing practice, it is difficult to see how current scientific arguments have the ability to influence actions which have independent economic and institutional structures. The article analyzes what structures of argumentation might have an effect on on-going and future METI, as well as the type of theological reflection that would likely contribute to this discussion.

Person-environment transactions in youth drinking and driving

Drinking and driving is a significant health risk behavior for adolescents. This study tested mechanisms by which disinhibited personality traits (impulsivity and sensation seeking) and aspects of the adolescent home/social environment (parental monitoring and alcohol accessibility) can influence changes in drinking and driving behavior over time. Two hundred two high school age youths were assessed at 2 time points, approximately 8 months apart. Zero-inflated Poisson regression analyses were used to test (a) an additive model, where personality and environmental variables uniquely predict drinking and driving engagement and frequency; (b) a mediation model, where Time 2 environmental variables mediate the influence of disinhibited personality; and (c) an interaction model, where environmental factors either facilitate or constrain the influence of disinhibited personality on drinking and driving. Results supported both the additive and interaction model but not the mediation model. Differences emerged between results for personal drinking and driving and riding with a drinking driver. Improving our understanding of how malleable environmental variables can affect the influence of disinhibited personality traits on drinking and driving behaviors can help target and improve prevention/intervention efforts.     

Guided saccades modulate face- and body-sensitive activation in the occipitotemporal cortex during social perception

Functional magnetic resonance imaging (fMRI) has identified distinct brain regions in ventral occipitotemporal cortex (VOTC) and lateral occipitotemporal cortex (LOTC) that are differentially activated by pictures of faces and bodies. Recent work from our laboratory has shown that the strong LOTC activation evoked by bodies in which the face is occluded is attenuated when the occlusion is removed. We hypothesized that this attenuation may occur because subjects preferentially fixate upon faces when present in the scene. Here, we experimentally manipulated subjects’ fixations while they viewed a static picture of a character whose face, hand, and torso were continuously visible throughout each run. The subject’s saccades and fixations were guided by a small fixation cross that made discrete jumps to a new location every 500 ms. Subjects were instructed to follow the fixation cross and make a button press whenever it changed size. In a series of blocks, the fixation cross shifted from locations on the face, on the hand, and to locations on a background image of a phase-scrambled face. In a second study, the fixation cross moved similarly, but the hand locations were changed to locations along the character’s body or torso. A localizer task was used to identify face- and body-sensitive regions of LOTC. Body-sensitive regions were strongly activated when the subjects’ saccades were guided over the character’s torso relative to when the saccades were guided over the character’s face. Little to no activity occurred in the body-sensitive region of LOTC when the subjects’ saccades were guided over the character’s hand. The localizer task was unable to differentiate body-sensitive regions in lateral VOTC from face-sensitive regions, or body-sensitive regions in medial VOTC from flower-sensitive regions. Guided saccades over the body strongly activated both lateral and medial VOTC. These results provide new insights into the function of body-sensitive visual areas in both LOTC and VOTC, and illustrate the potential confounding influence of uncontrolled eye movements for neuroimaging studies of social perception.     

Ability, breadth, and parsimony in computational models of higher-order cognition

Computational models will play an important role in our understanding of human higher‐order cognition. How can a model's contribution to this goal be evaluated? This article argues that three important aspects of a model of higher‐order cognition to evaluate are (a) its ability to reason, solve problems, converse, and learn as well as people do; (b) the breadth of situations in which it can do so; and (c) the parsimony of the mechanisms it posits. This article argues that fits of models to quantitative experimental data, although valuable for other reasons, do not address these criteria. Further, using analogies with other sciences, the history of cognitive science, and examples from modern‐day research programs, this article identifies five activities that have been demonstrated to play an important role in our understanding of human higher‐order cognition. These include modeling within a cognitive architecture, conducting artificial intelligence research, measuring and expanding a model's ability, finding mappings between the structure of different domains, and attempting to explain multiple phenomena within a single model.
