“…However, GTP experiences also showed failures of cognitive control and executive functioning when gamers were unable to override habitual sequences of responses to physical stimuli simulated in the game responding to those in similar ways as in the game, or when thoughts, urges, images, and sounds with videogame content arose while the gamers were engaged in tasks not related to the game (Ortiz de Gortari, 2015). Attention bias and disinhibition (Metcalf & Pammer, 2011;Van Holst et al, 2012) and studies suggest that videogame experiences contribute to failures of cognitive control (Bailey, West, & Anderson, 2010;Kronenberger et al, 2005;Mathews et al, 2005).…”

Previous qualitative studies suggest that gamers experience Game Transfer Phenomena (GTP), a variety of non-volitional phenomena related to playing videogames including thoughts, urges, images, sounds when not playing. To investigate (i) which types of GTP were more common and (ii) their general characteristics, the present study surveyed a total of 2,362 gamers via an online survey. The majority of the participants were male, students, aged between 18 and 27 years, and 'hard-core' gamers. Most participants reported having experienced at least one type of GTP at some point (96.6%), the majority having experienced GTP more than once with many reporting 6 to 10 different types of GTP. Results demonstrated that videogame players experienced (i) altered visual perceptions (ii) altered auditory perceptions (iii) altered body perceptions (iv) automated mental processes, and (v) behaviors. In most cases, GTP could not be explained by being under the influence of a psychoactive substance. The GTP experiences were usually shortlived, tended to occur after videogame playing rather than during play, occurred recurrently, and usually occurred while doing day-to-day activities. One in five gamers had experienced some A c c e p t e d M a n u s c r i p t 2 type of distress or dysfunction due to GTP. Many experienced GTP as pleasant and some wanted GTP to happen again.

“…On the other hand, if violence exposure predicts neural changes after controlling for age-related developments, then the evidence would support the hypothesis that such exposure affects brain development. These questions are significant given that the trajectory of cortical thickness and white matter maturation is linked to attention problems (Konrad & Eickhoff, 2010;Shaw et al, 2007) or other neurocognitive functions (Mabbott et al, 2006;Olson et al, 2009;Silveri, Tzilos, & Yurgelun-Todd, 2008), and both experimental and correlational research link media violence to deficits in attention and other facets of self-control (Bailey et al, 2010;Bushman & Huesmann, 2006;Kronenberger et al, 2005).…”

Media Violence Effects on Brain Development

Substantial research has indicated that media violence induces both short-and longterm increases in aggressive thoughts, feelings, and behaviors. Recently, neuroimaging techniques have begun to identify the mechanisms driving these changes. An important avenue that these neuroimaging tools can address is how exposure to media violence in childhood affects brain development, which can have lifelong behavioral consequences. This review highlights neuroimaging research examining how media violence exposure affects the pediatric brain. While such research is limited, evidence suggests that prefrontal mechanisms for controlling emotion and behavior are altered by exposure to violent media. Therefore, long-term increases in aggression and decreases in inhibitory control due to excessive media violence exposure may result from impaired development of prefrontal regions. However, additional neuroimaging research is necessary to establish whether and how exposure to media violence specifically shapes subsequent neural maturation. To optimize the use of neuroimaging in this inquiry, imaging studies should not stand on their own, but instead must be integrated with more traditional research paradigms to establish a more complete picture of effects. Future research must employ more longitudinal approaches to better characterize long-term effects that high exposure to violent screen media may have on brain development, particularly prefrontal and limbic brain regions. Keywords media violence, MRI, neuroimagingCharacterizing the effects of various forms of violent media on children's thoughts and behaviors has been a focus of psychological research for more than 50 years.American Behavioral Scientist 1-16

“…Taking decades to fully develop (Giedd, Blumenthal, & Jeff ries 1999 ;Luna, Th ulborn, Munoz, Merriam, Garver, Minshew et al, 2001 ), the prefrontal cortex and its specialized units can be damaged from environmental neglect or abuse, both early (Anderson, Bechara, Damasio, Tranel, & Damasio, 1999 ;Kodituwakku, Kalberg, & May, 2001 ) and late in development (Newman, Holden, & Delville, 2005 ). Th e prefrontal cortex is susceptible to damage in adolescence and early adulthood through physiologically addictive activities, such as binge drinking (Bechara, 2005 ) and violent video game play (Mathews, Kronenberger, Wang, Lurito, Lowe, & Dunn, 2005 ).…”
