Abstract

AbstractStudies on remote association tests (RATs) have mainly focused on cognitive processes involved in searching for remote associations. However, factors affecting these search processes and remote associations remain unclear. In order to address this issue, this study compared non‐chunking condition (e.g., “哲/财/由”) with perceptual chunking (two red color characters in the three‐character item “哲/财/由”) and semantic chunking (high‐frequency word‐pair in the item; e.g., “哲/学/由”, “哲学,” literally “philosophy”) conditions in the Chinese Remote Association Test (CRAT). The behavioral results on the CRAT found that the semantic ones resulted in significantly lower successful solving rates and longer response times than the other two conditions. The event‐related potential (ERP) results showed that in contrast to the perceptual‐chunking and the non‐chunking condition, the semantic‐chunking elicited enhanced P200, which might be related to the intuitive awareness of the mental fixation. However, relative to the non‐chunking condition, the two chunking conditions evoked increased N400 and late positive component (LPC), indexing the late reflection and implementation of cognitive control. Our results suggest that it is the early awareness of the semantic chunk, rather than the general cognitive control process involved in representing and solving the semantically and perceptually chunk‐induced interferences, that critically determines the final solving of RATs.
