Abstract

It was found that there were no effects of responses complexity within 2-selections task, but markedly without 2-selections tasks, as the response programming was examined by the complexity dissymmetry of 2 responses in 2-selections tasks and complexity of selecting responses. This hints that responses have been programmed before going to response, and not responding while programming. The concept on actions chunks was introduced, namely responses programming was the process of selecting actions chunks. The results confirmed if one expects to raise performance of an overt response R_i (R Î R_i | i = 1,2,...,n) in alternative responses R, then it is necessary to reduce the average complexity of the operation of the group R. If one reduces only the complexity of R_i, there is little hope in raising the performance.
