ELIMINATION OF TASK-SWITCHING COSTS
The study aimed at elimination of task switching cost with perceptual priming. Predictable task switching paradigm with task cueing and additional priming (i.e., neutral stimulus not requiring any response presented before the task) was used. Long cue-stimulus intervals were used. Task switching cost were calculated. In the first experiment switching cost were highly reduced (13 ms) in priming condition as compared to control condition (133 ms), and in the second experiment they where eliminated to the level not statistically significant (9 ms vs 109 ms, respectively). Although most of task switching studies showed that task switching cost are inevitable even if long preparation time is allowed, the study proved that these so-called residual costs can be eliminated if effective preparation is motivated by additional perceptual stimulation.
