Executive functions in insight versus non-insight problem solving: an individual differences approach

Original article can be found at: http://www.informaworld.com/smpp/title~content=t713685607~db=all Copyright Informa / Taylor and FrancisThis study investigated the roles of the executive functions of inhibition and switching and of verbal and visuo-spatial working memory capacities in insight and non-insight tasks. Eighteen insight tasks, 10 non-insight tasks and measures of individual differences in working memory capacities, switching and inhibition were administered to 120 participants. Performance on insight problems was not linked with executive functions of inhibition or switching but was linked positively to measures of verbal and visuo-spatial working memory capacities. Non-insight task performance was positively linked to the executive function of switching (but not to inhibition) and to verbal and visuo-spatial working memory capacities. These patterns regarding executive functions were maintained when the insight and non-insight composites were split into verbal and spatial insight and non-insight composite scores. The results are discussed in relation to dual processing accounts of thinking.Peer reviewe

Verbalization and problem solving: insight and spatial factors

Original article can be found at: http://www.bpsjournals.co.uk/ Copyright The British Psychological SocietyTwo groups of participants attempted eight examples of each of four different problem types formed by combining insight v. non-insight and verbal v. spatial factors. The groups were given different verbalization instructions viz., Silent (N=40) or Direct Concurrent (N=40). There were significant differences between insight and non-insight tasks and between spatial and verbal tasks in terms of solution rates and latencies. Significant interactions between the verbal v. spatial factor and verbalization condition on solution rates and latencies reflected a greater (negative) effect of verbalizing on spatial as against verbal problems. However, no significant interactions of the insight v. non-insight factor with verbalization condition on solution rates or latencies were found. These results favoured the “business as usual” view of insight problem solving as against the “special process” view which predicted larger effects of verbalization for insight problems as against non-insight problems.Peer reviewe

Critical thinking in the operating theatre

We know very little about the cognitive skills used by clinicians in the operating theatre. The critical thinking of expert surgeons and anaesthetists has rarely been studied. In this article, we examine the methods that have been used, both in simulators and in vivo, to study critical thinking of operating theatre team members, such as surgeons and anaesthetists. With difficulties in access to expert practitioners and in implementing control conditions, key methods are principally qualitative in nature and include observations 'in the wild' and in simulation, verbal protocol analysis in simulation, and retrospective interviews. A brief review of such studies suggests that critical thinking in the operating theatre involves not only decision making, as one would expect, but also situation awareness, risk assessment and communication skills.</p
