Аннотация: Abstract. An execution of computerized task was analyzed in simulated office environment1. Work of subjects in half of the cases was interrupted. Interrupting tasks varied in complexity. The main task was interrupted at different points. It was shown that (1) interruptions decreased accuracy of performance and increased the number of task related actions, but the time spent for the execution of the main task did not change; (2) more complicated interrupting tasks intensify subjects’ activity, consume more time for the resumption of the main task, but lead to a significant decrease in the number of errors; (3) the more difficult was a subtask in the moment of interruption, the more elaborated behavioral strategies were used in the condition of interference. Results were interpreted in the framework of Leontiev’s Activity Theory.
