背景颜色是一个重要的环境因素,大量研究表明背景颜色影响人的认知和行为表现。然而,背景颜色对认知控制的影响,是一个关键但又被忽略的问题。为了探讨清楚这个问题,本研究采用字母flanker任务,考察了灰色、蓝色和红色三种颜色背景条件下的一致性序列效应和干扰效应。结果发现,蓝色背景下的一致性序列效应不显著,而灰色和红色背景下均得到了显著的一致性序列效应。三种颜色背景均出现显著的冲突干扰效应,但它们之间没有显差异。这些结果表明,认知控制的在线调整受蓝色背景的干扰,冲突解决不受背景颜色的影响。本研究首次揭示了背景颜色对认知控制在线调整的影响,也进一步加深了我们对一致性序列效应的理解。
Background color is an important environmental factor, a large number of studies show that background color affect people’s cognitive and behavioral performance. However, the influence of background color on cognitive control is a crucial but neglected issue. In order to clarify this issue, we use the letter flanker task to investigate the consistent sequence effect and interference effect under the gray, blue and red color background conditions. The results showed that the consistent sequence effect was not significant under the blue background, but significant consistent sequence effect was obtained under the gray and red background. There were significant conflicting interference effects on the three color backgrounds, but no significant differences between them. These results show that the online adjustment of cognitive control is disturbed by the blue background and the conflict resolution is not affected by the background color. This study reveals, for the first time, the impact of background color on online adjustment of cognitive control and further deepens our understanding of the effect of consistent sequence.
