On the comparison between identification and discrimination tests in speech perception

Abstract

The conversion between identification and three forms of discrimination tests, based on the extreme assumption that discrimination performance in speech perception tests is determined solely by labeling in identification tests, is examined. Identical conversions are obtained for the two-interval same-different test, for the four-interval forced-choice test of pair similarity, and for the three-interval ABX test. Therefore, differences in discrimination performance among these tests are presumably due to their respective task requirements, not to differential prediction.
