幼儿在辨别过程中图形维度显著性的研究

采用Triad Classification法和等级图形模式研究了4～6岁幼儿在辨别过程中图形维度显著性效应。实验1让幼儿进行自由辨别任务,发现颜色显著性强于形状,局部特征的显著性强于整体特征;随被试年龄增长,整体特征和颜色的显著性逐渐增强;对维度显著性等级模式的信息加工比对整体局部特征等级模式的加工反应时长。实验2进行按指定标准来辨别的任务,发现仍然出现图形维度显著性效应。这些结果说明图形维度显著性效应可能是自动发生的,可能比整体局部特征的认知加工更复杂。

The Effect of Dimensional Salience on Preschool Children's Discriminability of Figures

In the present study,Thompson's triad classification task and Navon's hierarchical pattern stimuli were used to explore dimensional salience effects on of the children aged 4～6 years discriminability of figures.In experiment 1 on free matching.The result showed:.(1)color was more salient than shape,and local feature was more salient than the global.(2)the rate of accurate to discriminate based on color and global features increased as age increased;(3)it is faster to discriminate the task on local-global hierarchical pattern than to do the task on dimensional salience hierarchical model.In experiment 2 on matching by different instructions,The result showed that dimensional salience can significantly speed children's perceptual response and improve their accurate.It is suggested that the effect of dimensional salience probably automatically occurred at the early stage of cognitive process.
