Matching of successive auditory stimuli as a function of age and ear of presentation.
Subjects in three age groups matched pairs of tone stimuli as "Same" or "different." Combinations of stimuli were presented in succession to the Same ear or to different ears. Matching times increased with age but were not related to slowing of simple RT. Word stimuli were matched more rapidly than tone stimuli for all conditions, but RT scores suggested that subjects were matching in term of the physical properties of word and tone stimuli rather than verbal-nonverbal dimensions. "same" and "different" reaction times differed depending on ear of stimulus presentation. Sex differences were nonsignificant and no Sex by Age interaction was observed.
