The Influence of Video Games on Adolescent Brain Activity

The current study examined electrical brain activation in adolescent participants playing three different video games. Forty-five school aged children (M=14.3 years, SD=1.5) were randomly assigned to play either a violent game, non-violent game, or a non-violent game specifically designed to train the brain. Electroencephalography (EEG) was recorded during video game play. Results revealed an asymmetric right hemisphere activation in the alpha band for participants in violent game group, while those in the non-violent groups exhibited left hemispheric activation. Greater right activation in emotion literature denotes signs of withdrawal or avoidance from undesired stimulus. Implications of this finding as well as other findings related to electrical brain activation during video game play is discussed further in the manuscript

INVESTIGATING AGE-RELATED INHIBITORY DEFICITS IN SPATIAL WORKING MEMORY

Age-related inhibitory effects were investigated during spatial memory performance. In Experiment 1, 15 young (M = 20 years) and 16 old adults (M = 70 years) completed two spatial tasks (i.e., Block Suppression Test, Corsi Block Tapping Test) that differed in need for inhibitory processing. Accuracy differences within each task revealed age-related differences in spatial working memory and between task differences revealed that older adults had difficulty ignoring irrelevant items. Experiment 2 (10 young, 10 old adults) examined whether the distractibility of irrelevant items in the inhibition task (i.e. BST) accounted for the age-related inhibitory effects. Findings were largely consistent with the initial experiment indicating that inhibitory function was affected by adult aging

Examining Self-Care among Individuals Employed in Social Work Capacities: Implications for the Profession

Increasingly, the social work profession recognizes the need for more attention to self-care. Concomitantly, this growing awareness and ethical commitment is fostering a burgeoning self-care movement. However, despite recognition about the importance of self-care, there is a paucity of research that explicitly examines self-care practices among social workers. This cross-sectional study examined the self-care practices of individuals employed in social work capacities (n=1,011) in one southeastern state in the United States. Findings suggest that participants in the sample engaged in personal and professional self-care practices only moderately. Further, data suggest significant group differences in the practice of self-care, by relationship status, educational attainment, health status, and current financial situation, respectively. Overall, results indicate self-care as a potential area of improvement for participants in this study, in general, and perhaps for individuals employed in social work contexts, more generally

Physical Activity Barriers and Assets in Rural Appalachian Kentucky: A Mixed-Methods Study

Obesity is an increasing public health concern in the U.S. and a contributor to chronic illness, with trends revealing a rise in adult obesity and chronic disease rates among the most vulnerable and disadvantaged populations, including those in rural communities. A mixed-methods approach was used to examine perspectives on perceived physical activity barriers, resources, and level of community support. Researchers utilized the socioecological model to examine the multiple domains that support physical activity in rural Appalachia. The present study focuses on baseline data, including a cohort survey to assess physical activity, health status, and barriers to physical activity, and five focus groups with elected community leaders, community residents, members, and key stakeholders to assess perspectives on physical activity barriers and resources within the county. The cohort survey sample (N = 152) reported a median of 6 barriers (range 0–13) to participating in at least 30 min of physical activity daily. The qualitative analysis yielded three overarching themes related to physical activity participation: lack of motivation, physical environment, and cultural barriers. This mixed-methods study revealed the challenges and perceptions among rural residents across the socioecological model when assessing physical inactivity. Findings can be used to tailor future interventions focused on expanding social support, designing infrastructure, and creating policies that promote physical activity

Alpha to Omega: A Neurological Analysis of Marital Conflict in a Pilot Study

Although the linkage between health and marriage has been noted (e.g., Hayward and Gorman in Demography 41:87-107. doi:10.1353/dem.2004.0005, 2004; Kaplan and Kronick in J Epidemiol Community Health 60:760-765. doi:10.1136/jech.2005.037606, 2006; Schoenborn in Marital status and health: United States, 1999-2002. Advance data from vital and health statistics. National Center for Health Statistics, Hyattsville, MD, 2004), understanding the connection between neurological and behavioral phenomena in marital relationships has yet to be tackled. This pilot study attempted to address this limitation by analyzing electrical brain activity during a conflict interaction between married couples. Results generally supported the work of Lazarus (Emotion and adaptation. Oxford University Press, Oxford, 1991) and Harmon-Jones et al. (J Pers Soc Psychol 82:610-618. doi:10.1037//0022-3514.82.4.610, 2002); individuals that felt like they were in an action-possible situation revealed relatively higher left hemispheric activity in the frontal region of the brain. © 2014 Springer Science+Business Media New York

Brain Responses to Repeated Visual Experience among Low and High Sensation Seekers: Role of Boredom Susceptibility

To better understand individual differences in sensation seeking and its components, including boredom susceptibility and experience seeking, we examined brain responses of high and low sensation seekers during repeated visual experience. Individuals scoring in the top and bottom quartiles from a college-aged population on the Brief Sensation-Seeking Scale (BSSS) participated in an event-related potentials (ERPs) experiment. Line drawings of common objects were randomly intermixed and presented 1-3 times. Sixty-four channel ERP responses were recorded while participants classified items as man-made or not man-made in a repetition priming task. The two groups showed different ERP responses at frontal electrode sites after seeing a visual stimulus for 400-800 ms. The frontal late positive components (LPC) showed different habituation of ERP responses to new and studied repeated objects between high and low sensation seekers. Source localization analysis (LORETA) indicated that during visual stimulus adaptation the ventral pre-frontal cortex showed lack of frontal involvement among high sensation seekers. Furthermore, frontal LPC latencies during repeated visual exposure correlated with boredom susceptibility and experience seeking subscales. The distinct profiles of brain responses to repeated visual experience in high and low sensation seekers provide evidence that individual differences in neural adaptation can be linked to personality dimensions

Synaptophysin and synaptojanin-1 in Down syndrome are differentially affected by Alzheimer's disease.

Adults with Down syndrome (DS) develop Alzheimer's disease (AD) neuropathology by 40 years of age. Synaptophysin (SYN) consistently declines with age and is further reduced with sporadic AD. Thus, we hypothesized that SYN would be reduced in DS with AD. The gene for synaptojanin-1 (SYNJ1), involved in synaptic vesicle recycling, is on chromosome 21. We measured SYN and SYNJ1 in an autopsy series of 39 cases with DS and 28 without DS, along with 7 sporadic AD cases. SYN was significantly lower in DSAD compared with DS alone and similar to sporadic AD. Reduced SYN is associated with AD neuropathology and with Aβ levels in DS, as is seen in sporadic AD. SYNJ1 was significantly higher in DS and correlated with several measures of Aβ. SYNJ1 was higher in DSAD and significantly higher than SYNJ1 in sporadic AD. Although significantly higher in DS, SYNJ1 is further increased with AD neuropathology suggesting interesting differences in a synapse-associated protein that is overexpressed in trisomy 21
