项目摘要

The present study investigated decay and recovery processes in pattern recognition produced by prolonged viewing of various patterns.1.Disappearance of texture pattern was analyzed with varing eccentricity of stimulus presentation. The time for disappearance became shorter with the increase of eccentricity. It was found that a region which disappears in prolonged viewing is filled with the same texture elements as its outer area. This phenomenon can be explained by the Grossberg's theory which postulates the boudary contour system and the feature contour system.2.From analyzes of Kanji recognition times after prolonged viewing, significant delays were found not only when adaptation and test Kanjis were of the same pattern, but also when they had the same structure. The delay effect continued more than 15 sec after the prolonged viewing. The results also suggest that internal representations of Kanjis are partly independent from their size and orientation. These findings were published on an article in Japanese Psychological Research.3.The effects of prolonged viewing on recognition of facial expressions were also investigated. Siginificant recognition delays occurred only when the subjects viewed the faces which had higher values on the pleasantness dimension. In contrast, the prolonged viewing of faces which had high values on the arousal dimension produced no effect. It was suggested that there are at least two subsystems involved in the recognition of facial expressions and that each system has different temporal characteristics.

本研究调查了长时间观看各种模式所产生的模式识别的衰减和恢复过程。1.分析了不同刺激呈现偏心率下纹理模式的消失。随着偏心距的增加，消失时间变短。人们发现，长时间观看时消失的区域充满了与其外部区域相同的纹理元素。这种现象可以用格罗斯伯格理论来解释，该理论假设了边界轮廓系统和特征轮廓系统。2.从长时间观看后的汉字识别时间分析来看，不仅当适应汉字和测试汉字具有相同的模式时，而且当它们具有相同的结构时，都发现显着的延迟。长时间观看后延迟效果持续超过15秒。结果还表明，汉字的内部表征部分独立于它们的大小和方向。这些发现发表在《日本心理学研究》的一篇文章中。3.还研究了长时间观看对面部表情识别的影响。仅当受试者看到在愉悦度维度上具有较高值的面孔时，才会出现显着的识别延迟。相比之下，长时间观看在唤醒维度上具有高值的面孔没有产生任何影响。有人提出，至少有两个子系统参与面部表情的识别，并且每个系统具有不同的时间特征。
