Nowadays, a promising direction to study planning function is to combine psychological tasks with neuroimaging and EEG-methods. However, "tower tasks", traditionally used in these studies, cannot explain which cognitive processes are involved in planning and how these processes are measured by "tower tasks" (Koppenol-Gonzalez et al. 2010). Our stimuli were based on the Zak's tasks which were developed specially for planning skills research (Zak 1982). Tasks require move the chess knight on the 9 squares. According to Byrd, fixed-foreperiod and tasks complexity were taken into account (Byrd et al. 2011).The computer version consists of 50 tasks with three levels of complexity (the simplest problem requires 2 steps, the most difficult - 4 steps). The tests of procedure (N=31) found out the optimal duration period for tasks presenting (15s.) and answers presenting (5s.). Thus, the EEG-patterns, matching with planning process, can be revealed.
