Several theories have been proposed to predict performance when operators time share tasks. The Hemispheres as Resources Model suggests tasks will be performed efficiently together if each hemisphere allocates resources to one task. The Task Hemispheric Integrity Principle predicts the best dual task performance will be found when the shortest processing route is maintained. The purpose of the present study was to test the single and dual task performance predictions of these two models. The concurrent performance of two verbal tasks was used to compare the importance of ear of attention, hemisphere of processing, response hand and gender on task performance. Sixty-four subjects (32 males, 32 females) completed single and dual task trials of three verbal tasks; a dichotic listening task, an antonym match task and a continuous recall task.
The results of the present study provide mixed support for the Hemispheres as Resources Model and the Task Hemispheric Integrity Principle. There were gender differences in performance which indicate males are more lateralized for hemispheric functioning than females. The findings of the present study are discussed in terms of the theoretical implications and the implications for future research.
