Abstract

Recent research demonstrates that practice effects are attenuated through the administration of alternate-form memory tests. However, little is known about the degree of practice that can be expected when alternate forms of nonmemory tests are administered repeatedly. Two groups of healthy older adults were assigned to either a same- or alternate-forms condition. Participants completing the same forms of a confrontation naming task improved significantly over 4 testing sessions. On verbal fluency, participant performance significantly improved when completing only alternate forms. No significant practice effects were observed on tests of spatial processing. Practice effects caused by item-specific practice may be reduced via alternate test forms. However, similar reductions will be less apparent when practice effects are the result of test-specific practice.
