title: The measurement of performance asymmetries with dichotic stimulus presentation.
abstract: The failure to include only relevant observations in the assessment of laterality has resulted in a proliferation of post hoc attempts to "correct" laterality measures influenced by "overall performance level." The inclusion of information from trials in which both ears were either correct or in error contaminates the laterality measure (not overall performance per se). The use of single correct trial information obviates the need for adjusting laterality measures and lends itself to standard statistical procedures.
