人类写作活动的心理流程表现为认知——运思——表达。人脑所表现出来的复杂认知功能是以脑微观生物结构为基础的 ,电脑靠那些个“纯粹”的物质结构是难以做到的。创作运思中对源于自然和社会生活的丰富表象所蕴含意义的理解 ,更依赖于形象思维 ,电脑是无法模拟的。人脑表达的过程 ,是语义网络对表象意义不断地辨析、联想的过程 ,设想利用电脑替代人脑进行由心理深层的意念向表达表层的语言转换也是不可能的。因此 ,从人脑运思的机能特征和写作心理活动规律考察分析 ,电脑代替人脑写作是不可能的 Psychological process of human writing activities manifested as cognitive - ideas - expression. The complex cognitive function shown by the human brain is based on the structure of the brain micro-organisms, and it is very hard for computers to rely on those “pure” material structures. Understanding of the implications of rich representations stemming from nature and social life in the creative process depends more on imagery than on the computer. The process of human brain expression is the process by which the semantic network continually discriminates and correlates representational meanings. It is also impossible to envisage the use of computers instead of the human brain to transform the language from the deep psychological thought to the superficial expression. Therefore, from the perspective of the functional characteristics of the human brain and the psychology of writing activities, it is impossible for the computer to replace human brain writing
