Physiological Psychological Research of Biological Information Processing and Its Dysfunction

本研究的目的是对生物信息处理及其功能障碍的心理和生理机制进行合作和跨学科的研究。脑活动的电生理和/或生化迹象在正常或残疾的人和动物中进行检查，并与各种类型的疾病的行为迹象有关。这些研究分为三个主题；即(1)感知与认知，(2)学习与记忆，(3)意识与生物节律，三组研究者共享其中一项研究。主要研究结果总结如下：第一组研究人类的知觉和认知加工，主要是视觉信息加工。记录了正常成人和智力发育迟滞者在不同类型智力任务时的光或图形诱发电位。结果表明，正常人和残疾人的知觉加工过程与知觉加工过程密切相关，并进一步提出了正常知觉加工的脑机制的数学模型及其对残疾人功能障碍加工的意义。第二组研究了动物学习和记忆过程的大脑机制以及与各种人类疾病相关的机制。会议主题如下：鸟类的语言处理和语言障碍，精神药物和学习障碍的影响以及大鼠和癫痫的点燃神经元活动。这些研究结果显示了残疾人正常和异常学习过程的特定特征和神经生理生化机制。第三组研究了人类和动物的意识可变性。不同类型残疾人睡眠-觉醒节律或注意状态的电生理特征检测大鼠智力迟钝、视力障碍、注意缺陷等，并观察活动节律。这些研究结果表明，许多残疾人在胎儿期表现出特定的生物节律和/或注意力状态的异常迹象，并讨论了外部因素的重要性。在上一学期的研究中，对生理心理学技术在人类信息处理研究中的应用进行了综合讨论，认为残障者功能障碍的特点和原因可以通过脑机制来解释。少

Aims of this research is a co-operative and an interdisciplinary study of psychological and physiological mechanisms of biological information processing and its dysfunction. The electrophysiological and/or biochemical signs of brain activities both in normal or handicapped humans and in animals are examined and are related to the behavioural signs of various types of disorders. These studies are divided three themes ; i. e., (1) perception and cognition, (2) learning and memory, (3) consciousness and biorhythms, and three groups of investigators shared one of these research. The main results are summarized as follows :1. The first group investigated human perceptual and cognitive processing, mainly a visual information processing. Evoked potentials exposed by light or figures were recorded during the various types of mental tasks in normal adults and mental retarded. It was showed that the perceptual process were closely related to perceptual process both in normals and handicapped an … More d supposed the mathematical models of brain mechanism in nomal perceptional processing and their significance of dysfunctional processing in handicapped.2. The second group investigated the brain mechanism of learning and memory processes in animal subjects and related to various types of human disorders. The main themes were as follows ; speech processing birds and speech disorders, effects of psychotropic drug and learning disorders and kindled neronal activities in rats and epilepsy. These research results showed the specific characteristics of normal and/or abnormal learning process and neurophysiological and biochemical mechanisms in handicapped were supposed.3. The third group investigated the variability of consciousness both in human and animal subjects. The electrophysiological signs of sleep-awakening rhythm or attentional states in the various type of handicapped ; e. g., mental retarded, visual handicap, attention deficits, etc., and activity rhythm in rats were examined. These research results indicated that many handicapped showed specific abnormal signs of biorhythms and/or variation of attentional states and significance of external factors in fetal period were disussed.4. A synthetic discussion were conducted in the last research term and supposed that the physiopsychological techniques are very useful in the study of human information processing and that the characteristics and causes of dysfunction in handicapped may be specified by the brain mechanisms.
