摘　　要：采用任务转换范式,要求被试判断呈现数字的大小或奇偶性,考察了任务转换对SNARC效应的影响。结果发现:任务重复组被试对小数字用左手反应更快,对大数字用右手反应更快,任务重复组被试在数字认知加工中出现了经典的SNARC效应。相反,任务转换组被试在数字认知加工中未出现SNARC效应。由此可以推测,任务转换对SNARC效应具有抑制作用。The task switch paradigm was used to investigate the impact effect of task switch on the SNARC effect in this study.In the experiment,the participants were asked to determine whether the numerical magnitude presented in the middle of screen was smaller than five or larger than five,or determine whether the number presented in the middle of screen was odd or even and respond with the left or right key of keyboard fast and accurately.The results showed that the classic SNARC effect was observed in the task repetition group in processing the digital cognition,but the SNARC effect did not occur in the task switch group.It can be inferred from this experiment that task switch has an inhibitory effect on the SNARC effect.
