Abstract
This study investigated how three verbalization protocols, Silent, Type 1 (think-aloud), and Type 3 (explanatory verbalization), influence problem-solving performance on insight and non-insight problems within both spatial and verbal domains. Twenty-eight participants completed twelve problems (three per category) under each condition. Informed by theories of insight, verbal overshadowing, and cognitive load in working memory, the study assessed solution rates and log-trans- formed solution times. Verbalization did not significantly alter solution rates for any problem type. However, it imposed a clear time cost, significantly increasing solution times for spatial problems, an effect most pronounced under the cognitively demanding... (More)

Twenty-eight participants completed twelve problems (three per category) under each condition.

Verbalization did not significantly alter solution rates for any problem type. However, it imposed a clear time cost, significantly increasing solution times for spatial problems, an effect most pronounced under the cognitively demanding explanatory (Type 3) condition. Given the study’s sample size and specific design constraints, these findings should be considered preliminary. This study highlights the need for further research to elucidate how various verbalization types interact with the cognitive and representational demands inherent in problem-solving. (Less)
