摘要
采用带颜色的字母为靶刺激,通过操纵被试任务,考察辨别任务中认知控制对基于位置和颜色IoR的影响。结果发现:要求被试辨别带颜色的字母,没有出现基于颜色的IoR;要求被试辨别颜色,出现了基于颜色的IoR。说明,自上而下的认知控制是基于颜色IoR产生的关键因素之一。其内在机制可用抑制模型和注意资源分配理论从不同角度解释。同时,两种任务均未要求被试辨别靶刺激的位置,却都出现了基于位置的IoR,验证了Russell"注意可能存在对位置信息自动加工"的假说。
Using the colored letter as target, we investigated the top-down cognitive control on location-based and color-based inhibition of return in discrimination task, in which the requirements of the task were manipulated. The results showed that the color-based IoR was not observed when the subjects were asked to discriminate the colored letters, while it did happened when the subjects were required to manually report the color of the letters, suggesting that the cognitive control is an important factor in the appearance of color-based IoR under the condition of spatial uncertainty. The mechanism of which could be reasonably explained by both Tipper＇s inhibition mechanism and the distribution of attention resource theory from different perspectives. Moreover, the locationbased IoR consistently appeared in both subject tasks even though the subjects were not asked to discriminate the location of the targets, which supported the hypothesis of ＂attention may process location automatically＂ proposed by Russell.
