Effects of violent video games on aggressive behavior, aggressive cognition, aggressive affect, physiological arousal, and prosocial behavior: a meta-analytic review of the scientific literature

Research on exposure to television and movie violence suggests that playing violent video games will increase aggressive behavior. A meta-analytic review of the video-game research literature reveals that violent video games increase aggressive behavior in children and young adults. Experimental and nonexperimental studies with males and females in laboratory and field settings support this conclusion. Analyses also reveal that exposure to violent video games increases physiological arousal and aggression-related thoughts and feelings. Playing violent video games also decreases prosocial behavior.     

Unit Cohesion,Resilience, and Mental Health of Soldiers in Basic Combat Training

Military unit cohesion has been shown to correlate with physical and psychological outcomes. However, little is known about the development of cohesion in the early days of military service during Basic Combat Training (BCT) and how it relates to positive support and the negative stressors of training. The current study assessed the development of unit cohesion across the 10-week BCT period (N = 1,939), and the relation of cohesion to stress, resilience, mental health measures, and BCT outcomes (graduation, passing the Army Physical Fitness Test, and final Basic Rifle Marksmanship scores). The sample was primarily male (62%), under age 25 (88%), and unmarried (88%). All putative mediators showed significant change over time. Unit cohesion increased over time (slope 0.22; p < .001), and these increases were associated with decreases in psychological distress (p < .001), sleep problems (p < .001), and tolerance of BCT stressors (p < .001), as well as increases in resilience (p < .001), confidence managing stress reactions (p < .001), and positive states of mind (p < .001). Unit cohesion was indirectly associated with successful graduation and passing the Army Physical Fitness Test through cohesion-related improvement in psychological distress, resilience, and confidence managing reactions to stress. Sleep problems also mediated BCT graduation. Cohesion effects on the Basic Rifle Marksmanship scores were mediated by psychological distress and tolerance of BCT stressors only. These results suggest that unit cohesion may play a key role in the development of psychological health among new soldiers.     

Planning and Problem Solving Skills Following Focal Frontal Brain Lesions in Childhood: Analysis Using the Tower of London

Problem solving skills were investigated in children with focal lesions using the Tower of London test (TOL; Shallice, 1982). The scoring procedure was elaborated from previous studies to delineate separate processes contributing to overall performance in children. Thirty-one children with focal frontal pathology, 18 children with focal pathology in other brain regions (extra-frontal), 17 children with generalized pathology and 38 healthy children participated in the study. Results suggest a distributed network for problem solving skills, particularly cognitive flexibility and goal setting skills. Within the frontal group, children with lesions involving the right pre-frontal cortex had greatest problems with self-regulation, with rule breaks most common among this group. As these skills develop relatively early in comparison to other aspects of executive function, right pre-frontal regions may play a particularly important role in the development of executive skills in childhood, with damage to these regions rendering children vulnerable to a range of cognitive and social deficits.     

The Longitudinal Association of Marital Confidence,Time Spent Together,and Marital Satisfaction

Using three waves of dyadic data collected at 18‐month intervals from a community‐based sample of 610 newly married heterosexual couples (1 220 individuals), we examined the relationship between marital confidence, time spent together, and marital satisfaction using a modified actor‐partner interdependence model. Results indicate that after controlling for marital satisfaction and time spent together at Time 1, marital confidence around the time of marriage was associated with marital satisfaction approximately 3 years later. In addition, marital confidence was associated with how much time husbands and wives spent together at Time 2, which was related to marital satisfaction at Time 3. Tests of the mediating paths from marital confidence to marital satisfaction trended toward significance. The results suggest the importance of assessing for relationship confidence when working with couples in the early stages of their relationship.

Changes in person – organization fit: The impact of socialization tactics on perceived and actual P – O fit

This study examines the impact of socially oriented socialization tactics on changes in newcomer perceived and actual value-based person?–?organization (P?–?O) fit, and on the relations between these two measures of fit. Newcomers' fit was measured at entry (T1) and again after 4 months (T2) using the organizational culture profile (OCP; ). The results show that socialization tactics influence perceived fit, job satisfaction, and organizational commitment, but not actual fit. As hypothesized, perceived and actual fit become more congruent over time, suggesting a shift in newcomers' perceptions of the organization. Additional analyses were conducted to investigate the mediating influence of perceived fit on the relationship of investiture with job satisfaction and with organizational commitment and, for both outcomes, this was found to be significant. We discuss the implications for organization socialization procedures, research into newcomer entry using measures of actual and perceived fit, and HRM practices during the initial few months of organizational entry.     

Pure reason and contemporary philosophy of religion: the rational striving in and for truth

This essay urges contemporary philosophers of religion to rethink the role that Kant’s critical philosophy has played both in establishing the analytic nature of modern philosophy and in developing a critique of reason’s drive for the unconditioned. In particular, the essay demonstrates the contribution that Kant and other modern rationalists such as Spinoza can still make today to our rational striving in and for truth. This demonstration focuses on a recent group of analytic philosophers of religion who have labelled their own work ‘analytic theology’ and have generated new debates, including new arguments about Kant bridging philosophy and theology. Cultivation of a reflective critical openness is encouraged here; this is a practice for checking reason’s overly ambitious claims about God.     

Religion and Sexism: The Moderating Role of Participant Gender

The present study examined the relationship between gender, religious belief and ambivalent sexism. Specifically, this study tested the hypothesis that participant gender moderates the relationship between religious belief and ambivalent sexism. Three-hundred thirty seven Evangelical Christian undergraduate students from the Southwestern United States were administered the Ambivalent Sexism Inventory and the Christian Orthodoxy Scale. Results showed that gender moderated the relationship between Christian orthodoxy and Protective Paternalism. This finding suggests the importance of intervening variables, such as gender, in understanding the relationship between religion and sexism.     

Log-Multiplicative Association Models as Item Response Models

Log-multiplicative association (LMA) models, which are special cases of log-linear models, have interpretations in terms of latent continuous variables. Two theoretical derivations of LMA models based on item response theory (IRT) arguments are presented. First, we show that Anderson and colleagues (Anderson &; Vermunt, 2000; Anderson &; Böckenholt, 2000; Anderson, 2002), who derived LMA models from statistical graphical models, made the equivalent assumptions as Holland (1990) when deriving models for the manifest probabilities of response patterns based on an IRT approach. We also present a second derivation of LMA models where item response functions are specified as functions of rest-scores. These various connections provide insights into the behavior of LMA models as item response models and point out philosophical issues with the use of LMA models as item response models. We show that even for short tests, LMA and standard IRT models yield very similar to nearly identical results when data arise from standard IRT models. Log-multiplicative association models can be used as item response models and do not require numerical integration for estimation.
