认知加工中的表象表征与命题表征

Image Representation and Proposition Representation in the Recognition Process

表象是人认知加工构建的基础,不同材料(字符、数字、汉字和图形)在认知加工中存在表象表征与命题表征的方式,根据加工材料难易的不同,表象表征与命题表征在认知加工中所占比例不同,二者可以进行相互的转化。表象表征的容量有限,大小为4个组块。

Image is the important part in the recognition process.Image representation and proposition representation is basic form in image process of different materials,such as pictures,characters,numbles and letters.We found that a chunk of image representation.The chunk is four.When the capacity is less than four,image representation plays an important role in mental rotation＇s process.But,if the stimulus is very difficult,the capacity will be changed.Then proposition representation will dominate in mental operation.
