In cognitive psychology, the ideas of body and motor influence on mental processes are quite relevant. The set of these ideas forms a new direction in research – embodied cognition research program. However, despite the wide prevalence, only a small number of studies apply principles of this approach to study the phenomenon of insight. At present, there are several theories that try to explain mechanisms of insight problem solving in different ways: nonspecific approach, which denies differences in processes of solving insight and non-insight problems, and specific approach, which implies special mechanisms for insight problem solving. Our study, based on the ideas of embodied cognition research program and specific approach to understanding insight, examines insight problem solving depending on motor activity, which contains different types of principles of solving insight symmetry task: the principle of symmetry and the principle of chunk decomposition. Three experimental groups of motor activity were formed, which embody both principles of problem solving in different ways. Differences were found in the time needed for solving problems depending on associated type of motor activity. We found the facilitative effect of motor activity, which embodies both basic principles of insight problem solving. It is assumed that the presence of the problem solving principles in motor activity implicitly triggers the mechanisms of representation change. Future research plans are outlined to test the principles of solving insight task based on non-instrumental motor activity. The results are consistent with Ponomarev’s ideas on the role of a by-product in thought processes.
