项目摘要

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.

该项目的目的是研究大脑在图像处理中的功能。特别是，对正常人和脑损伤的人进行了七次实验，以检验法拉（1984）提出的模型。实验一以正常小学儿童为被试，进行表象产生实验（从阿拉伯数字生成汉字数字）和操作实验2中，正常成人被试被给予与实验1相同的任务。实验四是对正常成年人进行图像生成任务，要求被试判断图像中的假名字母是否包含平假名字母的左撇。实验5中，对左顶枕叶和右顶枕叶脑损伤的成年人进行与实验3相同的任务，实验6中，大脑左半球和右半球受损的被试被要求在大脑中移动汉字的两个偏旁并报告汉字，实验7中，大脑左半球和右半球受损的被试被要求在大脑中移动汉字的两个偏旁并报告汉字，实验6中，大脑左半球和右半球受损的被试被要求在大脑中移动汉字的两个偏旁并报告汉字。实验六的任务是给正常成年人的，这一系列实验的结果在很大程度上支持了左半球参与表象产生，而右半球参与表象操作的观点。
