1098.29 Cognitive process of insight: Representation change or progress monitoring, Jiang Qiu,
Qinglin Zhang, Southwest China Normal University, China
There are two cognitive theories of insight in problem solving, including the representational
change theory (Simon,1990) and the progress monitoring theory (Chronicle,1999). This article
studied 80 undergraduates’ cognitive process of solving the nine-dot problem by providing
different cues so as to investigate the cognitive mechanism of insight. The results indicated that
telling subjects to go outside the boundaries of the square had a very stronger effect on solution
than providing the first line (horizontal or diagonal line) of the solution. It suggested that the
representational change theory is the better indicator of performance in solving the insight
problem.
1098.30 A comparative study of mental models and mental logic in spatial reasoning, Qin Qiu,
Zhujing Hu, Cuanxuan Cao, Jianxi Normal University, China
Mental models and mental logic, which are the two sorts of theory in reasoning, give an
explanation to the inferential mechanism of spatial relations respectively. Two experiments were
designed to know which of the explanation is correct. The first experiment adopted two-factor
repeated measured design. One variable is the number of models, the other is the number of
inferential steps. Since the materials showed by oral language could cause an imagery-based
strategy, the second experiment used the literal materials presented by PowerPoint. The procedure
was similar to the first experiment. The results supported the mental model theory.
1098.31 Bayesian explain and experiments on diversity effect in inductive reasoning, Antao
Chen, Hong Li, Southwest China Normal University, China
By comparing experience-full task with experience-poor task, researchers find that the latter
facilitates more inductive reasoning than the former. Within experience-poor task, researchers deal
quantitatively and systematically with diversity, find that diversity effect is sufficient but
non-necessary condition of inductive reasoning. According to Bayesian, researchers put forward a
hypotheses that diversity effect consists of three successive and separate processing phases,
furthermore design complex cognition subsection delay (CCSD) to study thoroughly inductive
reasoning. Results show that CCSD is reasonable and feeling of surprise (FOS) in the second
phase is the key factor of diversity effect formation.
1098.32 On construction of thinking process model for children’s resolution of practical
mathematical problems, Xiaorong Wu, Dong Yang, Qinling Zhang, Southwest China Normal
University, Chongqing, China
Constructing the thinking process model for children’s resolution of practical mathematical
problems, the paper based on multiresearching methods such as oral reports & experiments on eye
motion has verified from diverse perspectives Model including literal representation, situational
representation, integral representation, structure-regulatory representation, arithmetical
representation and schematic representation, which hence has confirmed that the thinking process
during which children resolve practical mathematical problems is actually one of representations’
transforming constantly. In addition, the present study suggests that there lacks rigid linearity
among representations.
