关于早期知觉过程中注意资源分配权重的实验研究

A STUDY OF THE WEIGHT OF ATTENTIONAL RESOURCES ALLOCATED IN THE EARLY PERCEPTUAL PROCESS

本研究将早期知觉过程中分配的资源比例理解为权重。实验采用中心提示法，探讨了字母、数字、图形和颜色四种刺激特征的早期识别过程中资源分配权重问题。结果发现：（１）颜色不易受到提示的影响，而其它三个特征则受提示的影响较大；（２）在弱提示位置上，对数字的识别比对字母和图形的识别要难，而在强提示位置上，则相差不大。说明这四种刺激特征的注意权重在知觉加工的初始阶段是不同的；这种“不同”是早期知觉过程中刺激因素与注意资源分配之间相互作用的结果。

In the research weight was considered the proportion of attentional resources allocated in the earlyperceptual process. The sutdy used a central precuetechnique to explore the weight of attentional resources in terms of four features, namely, letter, digit, figure and color. The main results showed: 1) Color was not affected by the cuewhile the others, especially digit, were affected greatly by the cue. 2) Compared with letter and figure, digit was more difficult tobe identified in the location of invalid cues, while thedifficulty in identifying digit turned out to be the samein the location of valid cues. These results indicatedthat attentional weight in these four features was different in the early perceptual process. Such differencecame as a result of the interaction between stimulusproperties and attentional resource allocation.
