The lack of Aha! experience can be dependent on the problem difficulty

Area of Science:

• Cognitive Psychology
• Problem-Solving Research
• Insight Learning

Background:

• Previous studies on problem difficulty and insight problem-solving yielded conflicting results.
• Representational Change Theory (RCT) suggests difficulty arises from constraints and chunking.

Purpose of the Study:

• To investigate the effect of problem difficulty on insight problem-solving types.
• To examine both inter-problem (comparing different problems) and intra-problem (comparing variations of the same problem) difficulty contexts.

Main Methods:

• 165 participants solved original or hinted versions of the 8-coin and 9-dot problems, with hints designed using RCT principles.
• Participants self-reported an "Aha!" experience to classify solutions as insight or non-insight.
• Solution-type rates were compared across different difficulty levels and problem types.

Main Results:

• 56.1% of correctly solved insight problems were reported with an "Aha!" experience, indicating correct solutions do not always equate to insight.
• Inter-problem comparison: The easier 8-coin problem showed higher insight rates than the harder 9-dot problem.
• Intra-problem comparison: Harder (hinted) versions of problems were more likely to be solved with insight.

Conclusions:

• Problem difficulty's effect on insight is context-dependent, requiring consideration in future research.
• Higher "suddenness" scores predict insight solutions, even after accounting for problem difficulty.
• Distinguishing between correct solutions and genuine insight experiences is crucial.
