This investigation was designed to determine the validity of two categories of neuropsychological measures of cerebral dominance. Forty right-handed subjects were administered two dichotic listening tests and two hemispheric competition tests in a random order. The principal data showed that none of the four tests had sufficient levels of criterion-related and concurrent validity to be considered clinically useful in measuring laterality. In addition, a Baysean analysis of one of the dichotic listening tests indicated that it possessed a predictive validity of .79. Finally, the assertion that the scoring methods of each test are dynamically different was disputed, and Kinsbourne's interhemispheric competition model was not supported by the data.
