【摘要】 本实验结果表明,弱智儿童大脑两半球在认知速度(反应时间)上有明显障碍,但在认知正确度上无异子正常儿童;这一结果在左视野、右视野和双视野呈现刺激的三种条件下,以及在汉字和图形两种刺激材料之间,均未见明显差异。因此,本实验结果对国外关于学习障碍脑机制的“左脑障碍说”、“右脑障碍说”和“左右脑协同障碍说”均不支持。更多还原

【Abstract】 The results of this experiment showthat retarded children’s cognitive speed(namely,reaction time)is evidently handicap-ed by both the left and right cerebral hemi-spheres,but their cognitive errors are the sameas those of the normal children;and thereare no significant differences under RVF,LVF and BVF stimuli,or under chinese char-acter stumuli and figure stimuli.Therefore,our study supports neith“Left-brain handi-cap theory”,nor“Right-brain handicap the-ory”nor“Both brain transferring handicaptheory”of Western researchers’cerebralmechanism of learning disorder.更多还原
