Abstract


Did not pay attention to blindness research has important significance for revealing the two control process - digitally driven relationship between processing and concept-driven processing. Did not pay attention to the occurrence of blindness phenomenon, to some extent explicit attention capture failure. Attentional capture the traditional research often use additional singular stimulus paradigm more emphasis on the stimulus relatively significant characteristics on did not pay attention to the impact of blindness, is considered to be a purely stimulus-driven process, and for the role of top-down cognitive control Little research has been. Selective attention task, the role of working memory has a goal-oriented cognitive control, it can maintain the target processing priority, can actively suppress irrelevant stimulus interference. Working memory as embodied cognitive ability to control one aspect of individual differences. The purpose of this study is to: not pay attention to the impact of blindness, by testing different working memory load on to explore the role of working memory cognitive control to not pay attention to blindness. In this study, including pre-experiment and the main experiment, first test working memory operation span test distinguish between high and low working memory capacity. From 150 college students, selected the best and worst scores were 40 each. The main experiment was a 2 (working memory span) × 2 (with or without additional stimulation) × 2 (working memory load level), multi-factor mixed experimental. Whether the additional stimulus of the variables in the group; level of working memory load, working memory span subjects variable. Dual-task paradigm, combine the task of working memory and perceptual judgment task. In this study, the following results: (1) central control capability is an activator mission objectives in working memory, the ability to suppress irrelevant stimulus with individual differences and limited processing tasks simultaneously cognitive control participation will lead to resource competition for machining processes blocked. (2) dual-task paradigm, the improvement of working memory load of lowering the not pay attention depending on the blindness of the occurrence, a significant main effect; subjects memory breadth of the level is to pay attention to control the ability to reflect, its not pay attention to the phenomenon of blindness of produce has a role in promoting. Visible is also an important active suppression of irrelevant stimulus did not pay attention to blindness phenomenon. (3) operation of the breadth and working memory load interaction significantly, in particular, reflects the differences in the reaction of the breadth of high operational test under different levels of memory load; different working memory span test Note that the control mechanism is not the same.
