Individual differences in neurobehavioral measures of laterality and interhemispheric function as measured by dichotic listening.

Full Abstract

This article presents analysis of dichotic listening performance in 57 healthy men and women aged 20 to 72 years. The data are presented as a means to cover 2 theoretical issues relevant to the biobehavioral study of laterality and interhemispheric relations. First, the sensitivity of dichotic listening performance to factors such as sex, age, and their interactions was examined. Dichotic listening asymmetry scores were found to vary as a function of sex, age, handedness, and family history of developmental language disorders. The effects of sex and age were then explored in relation to a comparison of nonforced and unilaterally focused test conditions. The results suggest that even within a healthy, normative sample of human participants, individuals vary not only in their underlying perceptual asymmetries for auditory input, but also in the manner in which such asymmetries interact with other higher order cognitive functions.
