摘　　要： 从认知过程的角度考察注意焦点转换中的返回抑制产生的原因。两个实验要求被试为三个图形分别保持一个数字。实验1设置两种任务：＂提取且更新任务＂要求被试每次提取一个图形的数字,并对数字进行更新;＂提取任务＂要求被试只需提取图形的数字,而无需对数字进行更新。实验2设置＂更新任务＂,要求被试只需更新图形的数字,而无需对数字进行提取。实验同时设置抑制转换类型和控制转换类型,以考察返回抑制现象。结果表明,在＂提取且更新任务＂和＂更新任务＂中存在返回抑制现象,而在＂提取任务＂中未发现返回抑制现象。这说明,注意焦点转换中的返回抑制现象与更新过程有关。 The study investigated which cognitive processes were involved in backward inhibition in switching of the focus of attention.Two experiments required participants to hold three digits in three different figures.In experiment 1,two tasks were manipulated,＂retrieval and updating task＂required participants to retrieve one of three digits,and update this digit,and ＂retrieval task＂required retrieval but no updating.In experiment 2,＂updating task＂was manipulated,which required updating but no retrieval.In both experiments,two kinds of stimulus types,namely＂inhibition switching type＂and＂control switching type＂,were manipulated to explore backward inhibition.Results showed that backward inhibition existed in both ＂retrieval and updating task＂and＂updating task＂,but not in＂retrieval task＂.It is concluded that updating process is involved in backward inhibition in switching of the focus of attention.
