Abstract

Introduction: It was shown that directing early attention toward the target location enhances sensory-perceptual processing of the target. However, it is not clear whether visual-spatial attention is controlled by the limited capacity of central attention. This study aimed to investigate behavioral and electrophysiological changes, directing early attention on central attention limitations of dual tasks with various difficulty levels. Methods: Twenty-four participants were selected voluntarily, and they were randomly assigned into two groups with simple and selective. A dual-task paradigm with and without cue was incorporated in which the second task was either detection or discrimination, and the cue was presented before the first stimulus. The stimulus onset asynchrony between the first and second stimulus was 200, 400, and 800ms. The response time to the first and second stimulus and event-related potential was recorded and analyzed. Results: The simple pattern had a faster response time than the combined pattern. Also, the response time of the target in the valid position was faster than the invalid position. The lowest response time was for the simple group and the highest for the selected group. The main effect of pattern, group, and time interval on primary sensory components P1 and N1 was significant. Conclusion: Facilitating the early sensory-perceptual by directing attention toward the cued location would reduce the dual-task interference.
