The difficulty of achieving insight is usually explained by a number of factors. According to modern scientific theories, the difficulty is determined by perceptual and procedural factors, as well as the factor of the solver's motor activity, which can contribute to solving problems. The main goal of this work is to study the role of motor activity in solving the insight nine-dot problem. In this study, we provoke subjects to solve the nine-dot problem from a certain side (left or right). The motor activity embodies the principle of solving the problem from the left or from the right side. We assume that provoking a solution from the left side will lead to a faster representation change and effective problem solving, because it will reduce the problem space and provoke the most frequent and simple solution from the left dot. To activate motor activity, we have developed tasks similar to Schulte tables. We demonstrated that the motor activity, provoking a solution from a certain side, contributes to an increase in the number of trials made from that side. There were no significant differences in the number of participants who solved the main problem or in the number of trials that went outside the square between the groups with provocation from the right or the left side. Thus, motor activity influences the process of solving the nine-dot problem; however, provocation from the left side does not contribute to overcoming the sources of difficulty, which contradicts our hypothesis.
