发散思维的序列位置效应：创新想法动态产生机制的新视角

p>The serial order effect in divergent thinking (DT) is one of the most robust findings in the field of creativity research. This effect refers to the phenomenon that the number of generated ideas decreases, whereas the originality of ideas increases across time while performing DT. Both association theory and executive control hypothesis contribute to explaining&nbsp;the serial order effect, but the association theory and the executive control hypothesis focus on explaining individual differences in the serial order effect and cognitive processing, respectively. Previous neuroimaging studies have found gradually increased activation in the posterior areas of the posterior default network (i.e., precuneus and posterior cingulate gyrus) and the salience network (i.e., bilateral insula and dorsal anterior cingulate gyrus) was associated with the generation of serial novel ideas. In the later stage of DT, the energy of alpha of the temporal-parietal region, as well as&nbsp;the cooperation between the executive control network and the default network is&nbsp;increased, suggesting that internally-directed cognitive processes play a key role for the originality of the later serial ideas. Future research needs to combine cognitive and computational models, semantic analysis, brain dynamic analytical approaches, and representational similarity analysis to explore the cognitive and neural mechanisms of the serial order effect, as to provide a new perspective for deconstructing the dynamic process of creative thinking.</p
