| 摘 要： | 考察分心作业对环境主导注意型运动员返回抑制时程的影响。采用线索—靶子范式,试验1和试验2分别以普通大学生、新手型运动员和专家型运动员各16名作为被试,包括3种SOA水平(200 ms,400 ms,700 ms)。在试验1和试验2的中央注视点分别安排无分心作业和有分心作业,对3组被试之间的返回抑制时程进行比较。试验1结果表明:无分心作业时,普通大学生在SOA为400 ms和700 ms出现返回抑制,新手型运动员和专家型运动员在SOA为200 ms、400 ms和700 ms均出现返回抑制;试验2结果表明:有分心作业时,普通大学生与新手型运动员的返回抑制消失,专家型运动员在SOA为400 ms和700 ms仍然保留返回抑制。环境主导注意型运动员具有更强的返回抑制能力,专家型运动员能够采取更为有效的注意加工策略,表现出较好的认知控制能力或抗干扰能力。

| Abstract: | This aims to investigate the effects of distraction task on the time courses of inhibition of return for circumstance attention type athletes.Adopting cue-target paradigm,the subjects were 16 normal university students,16 novice athletes,and 16 expert athletes respectively in experiment 1 and 2.Experiments include three SOA(200/400/700ms).There were distraction task at central fixation point in experiment 1,and no distraction task in experiment 2.The experiments compared the time courses of inhibition of return among 3 groups.The results of experiment 1 showed that in the condition of no distraction stimuli,normal university students tend to occur inhibition of return in SOA=400ms and 700ms,novice athletes and expect athletes in SOA=200ms,400ms and 700ms.The results of experiment 2 showed that in the condition of distraction stimuli,inhibition of rectum completely disappeared for normal university students and novice athletes,while expert athletes tend to occur inhibition of return in SOA=400ms and 700ms.Circumstance attention type athletes have stronger abilities to inhibition of rectum.Expert athletes have more effective attention processing strategies and better cognitive control ability or anti-interference ability. |
