Abstract
Games are one of the fastest growing and most exciting forms of entertainment. Whether casual mobile game playing has a cognitive, physiological, or behavioral effect on players whose game use is not pathological is unknown. Here we explored whether preattentive auditory processing is linked to the behavioral inhibition system (BIS) in frequent and infrequent game players. A total of 74 subjects who were enrolled in our study were divided into two groups, 40 subjects were frequent gamers and 34 subjects were age-, gender-, IQ-, and education-matched infrequent gamers. All participants underwent a passive auditory oddball paradigm and completed the behavioral inhibition/behavioral activation system scales. The mismatch negativity (MMN) latency was shorter for the frequent gamers relative to the infrequent gamers, whereas no difference in MMN amplitude was found between groups. MMN amplitude was negatively associated with the degree of behavioral inhibition in the frequent and infrequent gaming group. We also found that those who frequently play games show an enhanced processing speed, which could be an effect of game practice. Greater behavioral inhibition induces increased vigilance, and this may have enhanced the MMN amplitude in the infrequent gamers. This differential pattern of correlations suggests that differences in the BIS could lead to different approaches to auditory information processing.
