Cognitive psychological study of imagery generation and operation.

该项目的目的是研究大脑在图像处理中的功能。特别是，为了检验Farah(1984)提出的模型，对正常的完好无损的和脑损伤的人进行了七次实验。实验1给正常小学生图像生成任务(由阿拉伯数字生成汉字数字)和操作任务(识别旋转数字)。在实验2中，正常成人被试被给予与实验1相同的任务。在实验3中，正常成人被试被给予图像生成任务，被试必须判断图像中的Kanakana字母是否包含来自平假名字母的左笔画。在实验4中，大脑损伤成人的左侧顶枕叶和右侧顶枕叶被给予与实验3相同的任务在实验6中，左右半球脑损伤患者被要求在心理上移动汉字的两个部首并报告汉字。在实验7中，实验6的任务交给正常成人。这一系列实验的结果基本支持左脑参与表象生成，而右脑参与表象操作过程的观点。

The aim of the project was to investigate brain function in imagery processing. In particular, seven experiments with normal intact and brain damaged people were conducted to examine the models proposed by Farah(1984). The models proposed that the generation of imagery is the role of the left hemisphere not of the right.In Experiment 1, normal primary school children were given image generation(generate Kanji numeral from Arabic numeral)and operation(identify rotated numeral)tasks.In Experiment 2, normal adult subjects were given the same task to that of Experiment 1.In Experiment 3, Normal adult subjects were given image generation task where subjects have to decide if imaged Kanakana letter contain leftwerd stroke from Hiragana letter.In Experiment 4, brain damaged adults with left parietooccipital lobe and right parieto-occipital lobe were given the same task to that of Experiment 3.In Experiment 5, brain damaged patient with left or right cerebral hemisphere were given the same task to that of Experiment 3.In Experiment 6, brain damaged patients with the left or the right hemisphere conducted new task in which subjects were requested to move two radicals of Kanji mentally and to report the Kanji.In experiment 7, The task of Experiment 6 was given to normal adult subjects.The findings of these series of experiment largely support the view that the left hemisphere engages to an imagery generation whereas the right hemisphere engages to the imagery operation processes.
