The relationship between brain lateralization measured with self-reporting techniques and with dichotic listening

Hypotheses derived from brain lateralization research have had considerable influence on contemporary personal selection and training as well as upon communication and advertising testing. These applications, however, rely upon measurements the validity of which is not proven. In the present paper research on the validity of these measurements is reviewed and findings from studies aimed at throwing further light on the cross validity of selected measurements such as self-administered questionnaires, and dichotic listening are reported. The review as well as the reported findings suggests that one has to be cautious with the application of brain lateralization theories to normal individuals till more is known about the precise functioning of the alternative measurements applied. Eventually, research on cross validation of self-reporting techniques and dichotic listening with EEC-measures is suggested.
