Insight Problem Solving

Genes involved in dopamine (DA) neurotransmission, such as the catechol-O-methyltransferase gene (COMT), have been suggested as key genetic candidates that might underlie the genetic basis of insight. In a sample of Chinese college students, this study examined whether COMT was associated with individual differences in the ability to solve classic insight problems. The results demonstrated that COMT was not associated with insight problem solving and there was no gender-dependent effect. This study, together with previous studies, raises the possibility of a complex relationship between COMT and insight problem solving.

Abstract. A considerable number of behavioral and neuroscientific studies on insight problem solving have revealed behavioral and neural correlates of the dynamic insight process; however, somatic correlates, particularly somatic precursors of creative insight, remain undetermined. To characterize the somatic precursor of spontaneous insight, 22 healthy volunteers were recruited to solve the compound remote associate (CRA) task in which a problem can be solved by either an insight or an analytic strategy. The participants’ peripheral nervous activities, particularly electrodermal and cardiovascular responses, were continuously monitored and separately measured. The results revealed a greater skin conductance magnitude for insight trials than for non-insight trials in the 4-s time span prior to problem solutions and two marginally significant correlations between pre-solution heart rate variability (HRV) and the solution time of insight trials. Our findings provide the first direct evidence that spontaneous insight in problem solving is a somatically peculiar process that is distinct from the stepwise process of analytic problem solving and can be represented by a special somatic precursor, which is a stronger pre-solution electrodermal activity and a correlation between problem solution time and certain HRV indicators such as the root mean square successive difference (RMSSD).

Insights are often productive outcomes of human thinking. We provide a cognitive model that explains insight problem solving by the interplay of problem space search and representational change, whereby the problem space is constrained or relaxed based on the problem representation. By introducing different experimental conditions that either constrained the initial search space or helped solvers to initiate a representational change, we investigated the interplay of problem space search and representational change in Katona’s five-square problem. Testing 168 participants, we demonstrated that independent hints relating to the initial search space and to representational change had little effect on solution rates. However, providing both hints caused a significant increase in solution rates. Our results show the interplay between problem space search and representational change in insight problem solving: The initial problem space can be so large that people fail to encounter impasse, but even when representational change is achieved the resulting problem space can still provide a major obstacle to finding the solution.

Insight Problem Solving

In this article, we investigate insight problem solving by exploring the subjective AHA! experience as a function of restructuring of a problem. It has long been assumed that the AHA! experience is the direct consequence of restructuring. However, is this assumption justified?We will argue that a) the AHA! experience does not always result from prior restructuring and that b) solutions with accompanied AHA! do not underlie a single neurocognitive process. In this regard, we use a modified compound remote associates (CRA) paradigm designed to experimentally dissociate restructuring from the AHA! experience. Results indicate that solutions accompanied by an AHA! are often found also in absence of restructuring. This finding is explained by proposing distinct CRA solution processes that differentiate between AHA! solutions with and without restructuring. We predict that solutions with accompanied AHA! experience differ in their behavioral, neural and eye-tracking related signature as a function of restructuring. The results mostly support these predictions. These findings have implications for insight research: First, by only measuring the subjective AHA! experience especially using CRAs it cannot be implied anymore that restructuring has occurred. Second, it is vital to experimentally separate the different components of insight to better understand its underlying diverse neurocognitive processes.
