Psychopathy and aggressive behaviour among Nigerian male prison inmates: The moderating role of substance abuse

This study investigated the moderating role of substance abuse in the relationship between psychopathy and aggression among male prison inmates. Two hundred and sixty-seven male prison inmates from the Nigerian Prison Services were participants. The inmates were incarcerated for armed robbery (27.3%), theft (31.1%), murder (12.8%), rape/assault/child abuse (19.1%), burglary/arson (5.6%) and kidnapping (1.5%) in Enugu prisons, Nigeria. Their mean age was 28.32; SD = 5.53. Their length of time in prison ranges from 1 to 12 years, with a mean of 3.38 years. Participants responded to self-reported measures of aggression, psychopathy, and drug abuse. The result of the moderated regression analysis indicated substance abuse to moderate the relationship between primary psychopathy and verbal aggression, and between secondary psychopathy and hostility. The study findings underscore the importance of psychological intervention aimed at addressing aggression among prison inmates with histories of substance abuse and psychopathy.     

Electronic Friend or Virtual Foe: Exploring the Role of Competitive and Cooperative Multiplayer Video Game Modes in Fostering Enjoyment

Industry and scholarly sources both argue that multiplayer gaming and competition are important factors in creating enjoyment, but relatively little empirical work demonstrates this claim. This study uses an experimental design (N = 139) to evaluate the effects of different multiplayer modes on enjoyment, allowing participants to interact naturally with a confederate partner and manipulating both game mode and partner behavior in a game of Madden '08. Results show that enjoyment is significantly enhanced by the combination of competitive play and a friendly partner, and demonstrate that the quality of interpersonal interaction only partly accounts for this.     

How do socially anxious women evaluate mimicry? A virtual reality study

Being subtly mimicked leads to more positive evaluations of the mimicker. Socially anxious individuals (SAs), however, should respond differently. SAs would probably either not process mimicry due to self-focused attention or not appreciate such social behaviour. Consequently, we hypothesised that they would not think more positively about a mimicking person. To test this prediction, 25 SAs and 25 non-anxious controls (NACs), all female, interacted with two virtual men (avatars) separately. One avatar mimicked the participant's head movements while giving an opinionated speech, whereas the other did not mimic. Afterwards, participants evaluated the speeches and the avatars. As predicted, NACs evaluated the mimicking avatar and his speech more positively than the non-mimicking avatar. SAs, on the other hand, evaluated both avatars and their speeches the same; comparable to how NACs evaluated the non-mimicking avatar. These results conform to the notion that mimicking does not have positive effects on SAs.     

Implicit self- and other-associations in obsessive-compulsive personality disorder traits

This study investigated automatic associations with the self and with others in the context of obsessive-compulsive personality disorder (OCPD). Participants scoring high (n=20) or low (n=20) on DSM-IV OCPD traits performed three irrelevant-feature tasks in which language of the words (Dutch vs. English) was the relevant stimulus feature and word content (OCPD self-view, OCPD other-view, high self-esteem and low self-esteem) the irrelevant feature. Results showed that the high and low OCPD group differed with respect to both explicit and implicit OCPD cognitions. Typically, high OCPD participants showed better performance on OCPD-congruent trials than on OCPD-incongruent trials, whereas low OCPD participants displayed the opposite pattern. This was evident from a semantic Simon effect and from a semantic priming effect. Correlations between direct and indirect measures of OCPD beliefs and of self-esteem were low. Moreover, the indirect OCPD measures contributed uniquely and independently of explicit beliefs to the prediction of OCPD.     

The Theory of Male Reference Group Identity Dependence: Roles of Social Desirability, Masculinity Ideology, and Collective Identity

Data from 118 college men from the southeastern United States (U.S.) were analyzed using zero-order and partial correlations to test male reference group identity dependence theory’s propositions regarding the relations of male reference group identity attitudes (i.e., no reference group, reference group dependent, reference group nondependent similarity, and reference group nondependent diversity) with traditional masculinity ideology and dimensions of men’s gender-based collective identity (i.e., affirmative evaluation of collective identity, importance of collective identity). Male reference group identity attitudes yielded theoretically-consistent relations with the affirmative evaluation and importance of collective identity. Specifically, the no reference group attitudes were correlated negatively whereas nondependent diversity attitudes were correlated positively with affirmative evaluation; the group dependent attitudes were correlated positively with importance of collective identity; and the nondependent similarity attitudes were correlated positively with both affirmative evaluation of collective identity and the importance of collective identity. This pattern reveals the differential salience of collective identity dimensions in male reference group identity attitudes, suggesting that group dependent attitudes reflect importance of collective identity without an evaluation valence, nondependent diversity attitudes reflect affirmative evaluation whereas the no reference group attitudes reflect nonaffirmative evaluation of collective identity, and nondependent similarity attitudes involve both affirmative evaluation and importance of collective identity. Additional findings added to prior data suggesting reevaluation of the posited role of traditional masculinity ideology in male reference group identity theory. The pattern of findings was not changed by controlling for self-deceptive enhancement and impression management dimensions of social desirability.     

Bodies and other visual objects: the dialectics of reaching toward objects

Participants viewed video clips of a left or right-handed reach toward an object that was orientated with a handle to the left or right. They were required to classify the object by making a left or right-handed key-press and ignore the reach. These responses were, never-the-less, affected by the observed reach in ways which largely reflected the opportunities for complementary actions in the viewed scenes, given the simultaneous constraints of the object orientation combined with the direction and hand of reach. These influences are claimed to reflect the interdependency of the action possibilities that arise from a set of objects and agents in three-dimensional space that together determine behaviour.     

Response selection difficulty and asymmetrical costs of switching between tasks and stimuli: no evidence for an exogenous component of task-set reconfiguration

Four task-switching experiments examined the notion of an exogenous component of task-set reconfiguration (i.e., a process needed to shift task set that is not initiated in the absence of a task-associated figuration stimulus). The authors varied the complexity and familiarity of stimulus-response (SR) mapping rules to produce differentially time-consuming reconfiguration demands. Tasks with more complex or less familiar rules did not display increased switch costs, given that stimulus repetitions were excluded from the analysis. These results do not support the idea of exogenous reconfiguration. Moreover, stimulus repetitions inflated task-switch costs and did so disproportionately for tasks with increased response selection difficulty, thereby demonstrating that insufficient control of the sequence of stimuli may yield results that mimic those predicted by exogenous reconfiguration accounts.     

Distinctiveness and correlation in conceptual structure: behavioral and computational studies

Patients with category-specific deficits have motivated a range of hypotheses about the structure of the conceptual system. One class of models claims that apparent category dissociations emerge from the internal structure of concepts rather than fractionation of the system into separate substores. This account claims that distinctive properties of concepts in the living domain are vulnerable because of their weak correlation with other features. Given the assumption that mutual activation among correlated properties produces faster activation in the normal system, the authors predicted a disadvantage for the distinctive features of living things for unimpaired adults. Results of a speeded feature verification study supported this prediction, as did a computational simulation in which networks mapped from orthography to semantics.     

Importance effects on performance in event-based prospective memory tasks

In the present study we manipulated the importance of performing two event-based prospective memory tasks. In Experiment 1, the event-based task was assumed to rely on relatively automatic processes, whereas in Experiment 2 the event-based task was assumed to rely on a more demanding monitoring process. In contrast to the first experiment, the second experiment showed that importance had a positive effect on prospective memory performance. In addition, the occurrence of an importance effect on prospective memory performance seemed to be mainly due to the features of the prospective memory task itself, and not to the characteristics of the ongoing tasks that only influenced the size of the importance effect. The results suggest that importance instructions may improve prospective memory if the prospective task requires the strategic allocation of attentional monitoring resources.     

Moral creativity in science and engineering

Creativity in science and engineering has moral significance and deserves attention within professional ethics, in at least three areas. First, much scientific and technological creativity constitutes moral creativity because it generates moral benefits, is motivated by moral concern, and manifests virtues such as beneficence, courage, and perseverance. Second, creativity contributes to the meaning that scientists and engineers derive from their work, thereby connecting with virtues such as authenticity and also faults arising from Faustian trade-offs. Third, morally creative leadership is important at all levels of science and engineering.
