Reliability of performance for dichotic listening using two response modes

Stop consonant-vowel syllables were presented dichotically to eight normal-hearing adult females over eight weekly sessions under two response conditions: a two-choice forced mode and a one-choice preferred mode. Total number of correct responses and right-ear advantage did not vary significantly across sessions for either response mode. Ear laterality, measured using percent of error, did not vary between response modes. Substantial differences were found between subjects in accuracy and ear laterality, but individuals tended to perform consistently across sessions.
