Parallel visual and memory processes

We studied parallel processes: visual processes with the prosaccade, the no -saccade and the antisaccade task on the one hand and memory processes with the random tap task on the other hand. The random tap task is believed to be a pure interference task for the central executive component of working memory. The number of saccadic errors was found not to be influenced by tax ing the central executive, while the latency times were significantly incre ased both in the prosaccade and in the antisaccade task. The effect seen in the antisaccade task was expected since it is a non-automatic activity und er central executive control. Because the prosaccade task is an automatic a ctivity, an effect of central executive load was not expected. As an explan ation for our findings, we postulate that the prosaccade task is brought un der willed control of the central executive.
