Insights from the past: Does access to unsuccessful problem attempts facilitate restructuring in insight problems?

Creel, Emily Ann Williamson 10 May 2024 (has links) (PDF)
Insight problems are often comprised of a period of impasse during which no new attempts are generated followed by an abrupt realization of the solution arising from the restructuring of an initial flawed problem representation. However, the precise mechanisms precipitating these processes are still being investigated. One hypothesis is that analyzing the unchanging elements of previous attempts may facilitate restructuring. We investigated this hypothesis using three classic insight problems. Participants were provided either three common examples of unsuccessful problem attempts, their own problem attempts, or no previous attempts. The prior attempts conditions eliminate the need to rely on memory to access previous unsuccessful attempts so that this mechanism could be investigated. Individual differences in working memory capacity and cognitive reflection were also collected. While there was no overall effect of the prior attempts conditions, both working memory and cognitive reflection were identified as significant predictors of restructuring and solving across problems and conditions.

Establishing Predictors of Insight Problem Solving In Children: Age, Not Cognitive Control or Socioeconomic Status, Determines Immunity to Functional Fixedness

Ershadi, Mahsa January 2021 (has links)
Thesis advisor: Ellen Winner / Cognitive control, the ability to limit attention to goal-relevant information, subserves higher-order cognitive functions such as reasoning, attention, planning and organization. Counterintuitively, deficits in these functions have proven advantageous in certain contexts: low cognitive control means less filtering of attention, and such unfiltered attention leads to novel solutions in insight problem solving contexts. Insight is the clear and often sudden discernment of a solution to a problem by means that are not obvious, and it plays an indispensable role in creative thinking. This study examined whether insight problem solving is a compensatory advantage for children of low socioeconomic status because of their known deficits in cognitive control. One hundred and forty-eight children ages 4 to 11 years old, each completed two insight problem solving tasks (the Box Problem and the Pencil Problem) and a cognitive control task (the Flanker/Reverse Flanker). In addition, their parents completed a sociodemographic questionnaire, which was used as a measure of their socioeconomic status and child rearing values of obedience versus independence. No association was found between children’s socioeconomic status and their ability to use insight to solve a problem. Results did show that older children exhibited less cognitive flexibility than did to younger children, and that diminished cognitive flexibility correlated with older children’s ability to solve the Box Problem; however, this effect did not hold when age, sex, race, socioeconomic status, and parental report of obedience versus independence, were accounted for. Ultimately, age was the only significant predictor of children’s insight problem solving ability, such that older children were significantly more likely to solve the Box Problem and to arrive at a solution more quickly for the Pencil Problem compared to younger children. Findings from this study are explained using evidence from research on children’s tool innovation showing that young children are poor at inventing tools, and that older children’s ability to use objects for atypical functions may be the result of their greater exposure to and experience with tools. / Thesis (PhD) — Boston College, 2021. / Submitted to: Boston College.
