项目摘要

In this research project, we studied integration processes of features of visual stimuli, auditory stimuli, and visual-auditory complex stimuli. We designed the following three experiments to clarify a cognitive structure of a stimulus.A.In the first experiment, subjects judged whether a feature of a test stimulus was same or not with the corresponding feature of a learning stimulus. Subjects were instructed to attend color, form, or size of the stimuli before each trial session. The instructed feature was called relevant feature and the other features were called irrelevant features. As a result, recognition time of the relevant feature depended on the difference of an irrelevant feature between the learning and the test stimulus.B.In the second experiment, subjects judged whether a chord, which followed a tone, was in tune or out of tune. Response time was facilitated when a prime was same with a base tone of the target chord. This facilitation reduced when a prime was the third or fifth tone of the target chord, These results implied that a tone was a cognitive unit of a chord.C, In the third experiment, subjects read and pronounced a kanji character visually presented. Some of kanji characters were reversed along with vertical axis, horizontal axis, or both. Result said, reading time of the kanji transformed by two transformations was not a monotonous function of the reading time of the kanji simply reversed.

本研究主要研究视觉刺激、听觉刺激和视听复合刺激的特征整合过程。我们设计了以下三个实验来阐明刺激的认知结构：A.在第一个实验中，被试判断测试刺激的特征是否与学习刺激的相应特征相同。受试者被指示参加颜色，形式，或大小的刺激之前，每个审判会议。被指示的特征称为相关特征，其他特征称为不相关特征。结果，相关特征的识别时间取决于学习刺激和测试刺激之间的不相关特征的差异。B.在第二个实验中，受试者判断跟随音调的和弦是否合调。当启动音与目标和弦的基频相同时，反应时间更容易。实验三，被试阅读并发音一个视觉呈现的汉字。一些汉字字符沿垂直轴、水平轴或两者沿着反转。结果表明，经过两次变换的汉字的阅读时间不是汉字的阅读时间的单调函数，而是简单的颠倒。
