Investigated the possibility that evidence of frequency discrimination might be found when the experimental procedures involved the conjugate reinforcement of nonnutritive sucking. (SDH)

Determines whether an averaged evoked potential technique using a random-v-repetitive presentation mode could be used to study infant auditory discrimination. Results showed a main effect of presentation mode with shorter latency for random v repetitive. The shortest onset latency was for random stimulus at the fast rate. (Author/DB)

Focuses on auditory fusion (defined in terms of a listerner's ability to distinguish paired acoustic events from single acoustic events) in 3- to 12-year-old children. The subjects listened to 270 pairs of tones controlled for frequency, intensity, and duration. (CM)

Two experiments involving a total of 177 infants 8 to 11 months of age found that subjects used a global processing strategy like adults' in discriminating transformations of a six-tone melody. Subjects needed melodic contour and frequency range to judge new sequences, but, in easy tasks, they also used absolute frequency. (CB)

Examines whether age-related differences would be observed between young children and adults for discrimination of synthesized, five-format consonant-vowel syllables that differed in voicing onset time of the initial consonants. (HOD)

Two major implications of this study are that repeated testing is a necessity for young children, and that repeated contrasts may provide a more accurate assessment of phonological discrimination ability in children. (Authors/MB)

Three experiments investigated 4-, 6-, and 8-month-olds' perception of the audible, visible, and combined attributes of bimodally specified syllables. Results suggested that at 4 months, infants attended primarily to the featural information, at 6 months primarily to the asynchrony, and at 8 months to both features independently. (Author/KB)
