Abstract：The representational-change theory proposes two mechanisms for insight: constraint relaxation and chunk decomposition, which has been supported in many studies using matchstick as test materials. It is however unclear whether these two mechanisms can explain insight in Chinese logogriph tasks and if so, how the two mechanisms are triggered by external hints. In Experiment 1a and 1b, the normal reading meaning and the logogriph meaning of the logogriph were compared when participants were asked to understand the two. Experiment 1a showed that the normal reading meaning of the logogriph was easier to understand than the logogriph meaning. In Experiment 1b, a study - test paradigm was used where the normal reading meaning and the logogriph meaning were both provided. The results showed that the logogriph meaning helped relax the constraint from the normal reading meaning. Together, Experiment 1 demonstrates that semantic discrepancies between the normal reading meaning and the logogriph meaning caused difficulties in constraint relaxation. Experiment 2 examined two types of logogriph chunks. Tight chunks were logogriph chunks with embedded sub-chunks or chunks involving decomposition at the stroke level. Loose chunks were logogriph chunks without any embedded sub-chunks or chunks involving decomposition at the radical level. The results showed that it was more difficult to decompose tight chunks than loose ones as shown in the longer reaction time in the former than the latter. Experiment 3 examined how different types of elicitation affect constraint relaxation and chunk decomposition in the incubation period using a single factor design in 3a (type of elicitation: prototype, non-prototype or no elicitation) and a 2 × 3 design in 3b (type of chunk: tight or loose by type of elicitation: prototype, non-prototype or no elicitation). The results showed that prototype elicitation facilitated constraint relaxation and chunk decomposition more than non-prototype elicitation or no elicitation did. In conclusion, the cognitive mechanism of insight in Chinese logogriph can be explained in the framework of representational-change theory emphasizing constraint relaxation and chunk decomposition, both of which can be facilitated by prototype elicitation.
