Effects Of Domain Knowledge Based On Semantics And Image Representation On Creative Cognition Activity

As a unique competence for human and gradually popularized from genius to general population, creative thinking is closely related to individual knowledge awareness level. Semantics and image constitute two important modes of knowledge expression. So, how knowledge representation and thinking process will impact creative solutions distinct experts from novices? Based on the information processing theory, this research will carry on the discussion to this question. The information processing theory shows that human cognitive operation depends on the collaboration of semantic system and imaginary system. Image is the perceived source, setting a lot of attribute of things; the concepts’ connections and nest constitute a rich semantic network system. Above two act as both a cognitive source illuminating the creative problem solving, and the divergent and pioneering role. Modes of knowledge representation and activation by expert and novice become the key difference to solve creative problem. Ecological validity regarding study of creative thinking will be improved from points of view as expertise, cognitive process and behavioral analysis.Information processing theory, to some extent, illustrates that the existing knowledge experience will affect the process of creative thinking and results. This research embarks from the perspective of expertise, discussing the relationship between creative thinking and activation of semantic knowledge as well as selection of image. This research assumed that due to differences in the knowledge network, expert and novice would perform different degree on the subjective awareness of semantic distance in both inside and outside the domain field, leading to differences in the creative problem solving process in which choice and integration of domain knowledge, semantic knowledge and imaginary knowledge differed, thereby affecting creative thinking results’novelty and practicality.Experiment1:selecting subjects with significant differences in physics knowledge to judge subjective semantic distance (divided into " tight" and " loose ") of paired words both inside and outside the field (divided into " physical field pair words " and" general field pair words"). By random presentation the pair words corrected by expert teachers, namely "close pair words in physical field","distant pair words in physical field","close pair words in general field" and "distant pair words in general field", to investigate how different knowledge network width by novice and expert would affect the depth and velocity of semantic concept identification. The experiment tried to collect paired word distance score (1to7), judgement reaction time, self evaluation score and the actual physical knowledge level test data. Experiment2:expert and novice with significant difference in domain knowledge background would perform differently in creative achievements’novelty and practicality due to different cognitive processing mode (divided into "abstract thinking" and "image thinking"). Knowledge network and the way of thinking were the basis for expert to perform transfer ability generally. The experiment adopted mixed experimental design, namely2(divided into "rich domain knowledge" and "poor domain knowledge") x2(divided into "excellent sports knowledge" and "limited sports knowledge") x2(divided into "active sports participation" and "limited sports participation") with specific image (divided into "the choice of specific image as creative imagination base" and "not the choice of specific image as creative imagination base"), professional knowledge selection (divided into " with the help of the professional knowledge background and terminology design" and "without professional knowledge background and terminology design"), novelty score evaluated by expert teachers about the new sports idea and practicality score evaluated by expert teachers about the new sports idea (60to100) as the dependent variables. Subjects were asked to complete assignments including creative imaging task, design review, participants self assessment, sports knowledge testing and basic information.The results showed:1, semantic representation was different significantly between expert and novice. Knowledge was domanial. Individual with rich domain knowledge performed more clear judgement on subjective semantic relation of paired words. Domain knowledge may influence on the semantic definition and the individual self-efficacy for subjective judgments. Long time to make judgement on distant paired words showed that the expert was not blindly "fast".2, Domain knowledge background would affect cognitive operation contents and methods of thinking when individual solved the creative problem; differences in cognitive operation contents and methods of thinking leaded to the differences in creative products’ novelty and practicability, and novelty was complementary with practicability. The results showed that:background knowledge would affect the cognitive mode of creative thinking and lead to different creative results.
