Cautions in alternate-form presentation of aural test material: Speech Sounds Perception Test.
86 college students were administered the standard Speech Sounds Perception Test and an alternate recording. Although reliability between the two recordings was moderate (r = .68) when the standard was given first, but only .36 when the alternate form was given first, differences in performance were consistent with differences in attack and decay found in voice-print tracings. Results suggest caution in using an alternate form of a neuro-psychological test, particularly one using auditory stimuli, until cross-validation confirms the reliability coefficient and the level of performance.
