Video game violence: A review of the empirical literature

The popularity of video games, especially violent video games, has reached phenomenal proportions. The theoretical line of reasoning that hypothesizes a causal relationship between violent video-game play and aggression draws on the very large literature on media violence effects. Additionally, there are theoretical reasons to believe that video game effects should be stronger than movie or television violence effects. This paper outlines what is known about the relationship between violent video-game playing and aggression. The available literature on virtual reality effects on aggression is discussed as well. The preponderance of the evidence from the existing literature suggests that exposure to video-game violence increases aggressive behavior and other aggression-related phenomena. However, the paucity of empirical data, coupled with a variety of methodological problems and inconsistencies in these data, clearly demonstrate the need for additional research.

Gender-Specific Conflicts among Urban African-American Youth: The Roles of Situational Context and Issues of Contention

The literatures on violence among young men and young women have highlighted the importance of situational context. However, few studies have compared disputes that do not result in violence with those that do, and even fewer have been positioned to investigate the role situational context may play across gender in accounting for these outcomes. Drawing on recent scholarship on gender and violence, this research explores the situational contexts of youth conflicts among African-American adolescent boys and girls. Using a large sample of narrative accounts of 153 violent and nonviolent conflicts, we examine how youth describe the issues of contention in their conflicts, how these relate to the situational contexts in which conflicts emerge, and similarities and differences in the antecedents, contexts, and extent of male and female violence.     

The Use of Prospective Versus Retrospective Pretests with Child-Welfare Involved Families

The purpose of the current study is to examine the use of both a prospective and a retrospective pretest in evaluating the impact of the Strengthening Families Program on foster care involved families affected by parental substance abuse. Debate has existed in the literature for over 60 years regarding the use of retrospective pretests in assessing self-reported program impact, with key stakeholders often arguing strongly that, due to response-shift bias, sensitization, and the nature of many human service settings, retrospective pretesting may be more appropriate. However, program evaluators must also incorporate into the evaluation design funding mandates to collect data at specific points in time. In order to mitigate potential pretest-only biases and enhance the evaluation’s rigor, this study sought to address the pretest debate through the use of both a traditional, prospective pretest and a retrospective pretest. Using data provided by 411 caregivers, program effectiveness was measured in the areas of family, child and parent functioning. Statistical significance tests and effect sizes were analyzed to compare traditional prospective pretest to posttest scores and retrospective pretests to posttest scores. Findings indicate that overall, the Strengthening Families Program positively impacted family, child and parent functioning and that there were few differences between testing approaches when testing for statistical significance; however, relative differences between prospective pretests and retrospective pretests appeared more prominent in effect size computations. This research informs the longstanding debate, and suggests that program evaluators consider the advantages and disadvantages of using a retrospective pretest in design planning.     

The belief in a just world: an examination of reliability estimates across three measures

In this study, we utilized reliability generalization procedures to examine internal consistency estimates across 3 scales measuring the belief in a just world. The distribution of reliability estimates for the measures suggest low to moderate ranges of internal consistency reliability coefficients. The Global Belief in a Just World Scale (Lipkus, 1991) produced the highest average reliability score (alpha = .81) compared to the Just World Scale (Rubin & Peplau, 1973; alpha = .64) and the Just World Scale Revised (Rubin & Peplau, 1975; alpha = .68).     

The age deficit on photopic counterphase flicker: contrast, spatial frequency, and luminance effects.

This study evaluated the contribution of reduced contrast sensitivity and retinal illuminance to the age-related deficit on the temporal resolution of suprathreshold spatial stimuli. The discrimination of counterphase flicker was measured in optimally refracted young and elderly observers for sinusoidal gratings of three spatial frequencies (1, 4, and 8 cycles per degree) at three contrast levels (0.11, 0.33, and 0.66). Age deficits in flicker discrimination at the two higher contrast levels and at the two lower spatial frequencies were unrelated to observer contrast sensitivity. Flicker discrimination of young observers who carried out the task through .5 ND filters to simulate a two-thirds reduction of retinal illuminance in the older eye, was similar to that of the elderly observers. An age-related reduction in retinal luminance appears to be a major determinant of the age-related spatiotemporal deficit at suprathreshold contrast levels, although neural factors may also be involved.     

The effects of brief and extended stimulus availability on preference

The effects of stimulus availability on preference were evaluated using two conditions of a modified preference assessment. Different preference hierarchies were found in 15-s access conditions than in 15-min access conditions. Subsequent comparisons of a short-availability high-preference stimulus and a long-availability high-preference stimulus verified differential preferences for stimuli based on duration of availability.
