Action video game modifies visualselective attention;As video-game playing has become a ubiquitous activity in today’s society, it is worth considering its potential consequences on perceptual and motor skills;; This task measures the effect of a to-be-ignored distractor (错误诱导）on a target task. The size of this distractor effect has been proposed to provide an index of ‘left-over’ attentional resources. distractor effect is large when the target task is easy, but small when the target task is made dif?cult by increasing the number of ?ller shapes in the ring; Flanker compatibility task Participants were asked to decide whether a square or a diamond appeared within one of the six rings (target task), while ignoring a distractor shape presented outside the rings. ;when the target task is easy, spare attentional resources ‘spill over’ to the distractor, processing it to some extent and thereby in?uencing target processing. As the target task becomes more dif?cult, fewer attentional resources remain to process the extraneous distractor. Irrelevant processing is only truly prevented once the target task becomes so dif?cult that all available resources are devoted to the target task, leaving none to the distractor. If video-game players (VGPs) do indeed have a greater attentional capacity, they should exhaust their visual attention resources more slowly than non-video-game players (NVGPs) as the target task becomes more dif?cult. ;As predicted by the hypothesis of a greater capacity in their population, VGPs showed an overall distractor effect that remained even when the target task was dif?cult ;video-game playing enhances the number of visual items that can be unerringly apprehended. ;Inside this conclusion still remains a few questions.;;Result;What is Attentional blink(注意瞬脱);Attentional blink task.;Result;the source of the VGP and NVGP population differences.;;;;The training was successful as all participants improved their scores on the video game on which they w
