Multiple Resources and Brain Laterality.
Abstract
Two studies were completed to test the multiple resources model of information processing using tachistoscopic lateralized-input techniques. In Exp. 1 37 normal, dextral subjects, 18 men aged 18-21yr. and 19 women 18-21yr. responded manually to a visuo-spatial and verbal dual-task presented simultaneously to left and right brain or non-laterally. Both men and women tended to have superior performance with coherent lateral input. However, differences in task difficulty and the possibility of a left to right scanning advantage with lateral input made interpretation of the data tenuous. In the second experiment the difficulty of the two tasks were made more equal and a third viewing condition, having noncoherent lateral input, was included. Twenty normal, dextral subjects 10 men aged 18-21yr, and 10 women 19-21yr. were tested under all three viewing conditions. Both men and women had superior performance with coherent lateral input compared to the other two viewing condition. The results were viewed as supporting the notion that each hemisphere has separate and unique pools of resources, that the resources of one or both hemispheres may be functional in processing a given task, and that in dual-task situations the brain operates most efficiently accurately with direct access of appropriate tasks to each hemisphere.
