QUESTIONS OF CRITERIA - REPLY

In a reply to our report on hemisphere differences in processing band- pass filtered letters (Christman, Kitterle, & Niebauer, 1997), Peterze ll (1997) argues that our results are not attributable to hemispheric asymmetries in spatial frequency processing. Rather, Peterzell argues that factors such as response criteria and stimulus visibility can acc ount for our results. We argue that our results are attributable (at l east in part) to hemispheric asymmetries in spatial frequency processi ng, while at the same time we acknowledge the potential influence of o ther factors in the determination of hemispheric differences.
