Abstract

Two studies evaluated the interhemispheric transmission deficit explanation of reading disability comparing second- and sixth-grade poor and normal readers on learning and discrimination tasks that involved hemifield presentations of visual stimuli. In the first of these studies, in the main poor readers performed below the level of normal readers on paired associates learning, regardless of the visual field in which the stimulus appeared, thereby replicating previous findings. In the second study, no differences between reader groups were found on time taken to indicate presence or absence of a simple dot stimulus. It was concluded from the combined results that deficiency in inter-hemispheric transmission is not a significant cause of reading disability.
