Addressing the Association Between Action Video Game Playing Experience and Visual Search in Naturalistic Multisensory Scenes.

Prior studies investigating the effects of routine action video game play have demonstrated improvements in a variety of cognitive processes, including improvements in attentional tasks. However, there is little evidence indicating that the cognitive benefits of playing action video games generalize from simplified unisensory stimuli to multisensory scenes - a fundamental characteristic of natural, everyday life environments. The present study addressed if video game experience has an impact on crossmodal congruency effects when searching through such multisensory scenes. We compared the performance of action video game players (AVGPs) and non-video game players (NVGPs) on a visual search task for objects embedded in video clips of realistic scenes. We conducted two identical online experiments with gender-balanced samples, for a total of N = 130. Overall, the data replicated previous findings reporting search benefits when visual targets were accompanied by semantically congruent auditory events, compared to neutral or incongruent ones. However, according to the results, AVGPs did not consistently outperform NVGPs in the overall search task, nor did they use multisensory cues more efficiently than NVGPs. Exploratory analyses with self-reported gender as a variable revealed a potential difference in response strategy between experienced male and female AVGPs when dealing with crossmodal cues. These findings suggest that the generalization of the advantage of AVG experience to realistic, crossmodal situations should be made with caution and considering gender-related issues.

The Prevalence of ADHD and Comorbid Disorders in Iranian Adult Male Prison Inmates.

OBJECTIVE: The aim of the present study was to explore the prevalence of ADHD and comorbid disorders in a community sample of adult male prisoners in Iran. METHOD: Through stratified sampling method, 908 adult male prison inmates in Gorgan Prison were recruited on a voluntary basis. Diagnostic assessments were based on the Adult ADHD Self-Report Scale Screener and a clinical interview based on Diagnostic and Statistical Manual of Mental Disorders (4th ed.) criteria and psychiatric interview. Comorbid disorders were assessed with the Beck Anxiety Inventory, Beck Depression Inventory-Second Edition, and Millon Clinical Multiaxial Inventory-III. RESULTS: ADHD was present in 147 participants (16.2%). Eighty-five percent of participants with ADHD reported lifetime substance abuse. They had higher rates of mood (40.8%) and anxiety (55.1%) disorders. Antisocial and borderline personality disorders were also more prevalent among offenders with ADHD. CONCLUSION: ADHD is prevalent in offenders and it is associated with comorbid disorders. The results emphasize the necessity of treatment programs for offenders with ADHD.
