Theory of “intelligence current in creativite activities” eatabilished a model to explain the relationship between intelligence and creativity. This study compared intelligence and creativity from the characteristics of three elementary cognitive components (speed of information processing, working memory span and cognitive inhibition) and performance to explore the effectiveness of this model. The subjects were recruited from a junior middle school located in a county town. Study 1 and study 2 explored the difference of elementary cognitive components and function between intelligence and creativity. According to the results of the study 1 and study 2, the relationship of intelligence and creativity was modeled in study 3. Some results supported the opinions of “intelligence current in creative activities”: (1) Intellectual level or intelligence potential servered as the basis of creativity. (2) One’s emtional state about learning serves as a switch to moderate the relationship of intelligence and creativity. While other results came to conclusions which denied the major viewpoints of “intelligence current in creativites”: (1) The opinion to think creativity as a function of intelligence wasn’t of full evidence because there was some unique characteristic of speed of information processing with creative persons, and the forecast of intelligence to creativity is very low, even with high emtion feeling condition. (2) Creativity was some ability different from intelligence. Intelligence emphasized on some facets of cognitive ability, while creativity emphasis on other facets of cognitive ability and even some non-cognitive ability. 2a) The basic cognitive characteristic of intelligence reflected in the speed of information processing and the extension of working memory. Intelligence has the medium relevance with them, but has no significant relevance with cognitive restrain. 2b) The basic cognitive characteristic of creativity reflected in: creativity has the positive relevance with the speed of information processing. The impact mechanism probably is the delay effect of disperse attentive. This delay effect will lead the positive relationship between creativity and the speed of information processing instable. And the creativity also has no significance relationship with the extension of working memory and the cognitive restrain. 2c) Both of intelligence and creativity have the special contributions to academic achievement. The contribution from creativity to academic achievement effected by emotion feeling towards learning. 2d) Emotion, interest attitude and so on, such as learning emotion feeling, are also the basement of creativity.
