Carruthers, Sarah; Stege, Ulrike; Masson, Michael E. J. – Journal of Problem Solving, 2018
The role that the mental, or internal, representation plays when people are solving hard computational problems has largely been overlooked to date, despite the reality that this internal representation drives problem solving. In this work we investigate how performance on versions of two hard computational problems differs based on what internal…

Fleischer, Pierson; Hélie, Sébastien; Pizlo, Zygmunt – Journal of Problem Solving, 2018
Gestalt psychologists pointed out about 100 years ago that a key to solving difficult insight problems is to change the mental representation of the problem, as is the case, for example, with solving the six matches problem in 2D vs. 3D space. In this study we ask a different question, namely what representation is used when subjects solve search,…

Blokpoel, Mark; Wareham, Todd; Haselager, Pim; Toni, Ivan; van Rooij, Iris – Journal of Problem Solving, 2018
The ability to generate novel hypotheses is an important problem-solving capacity of humans. This ability is vital for making sense of the complex and unfamiliar world we live in. Often, this capacity is characterized as an inference to the best explanation--selecting the "best" explanation from a given set of candidate hypotheses.…
