Infants were tested for their discrimination of changes in the melodic contour (direction of successive pitch changes) of brief melodies in the context of discernible variations in key or interval size. (PCB)

Assessed auditory temporal acuity among infants of 3, 6, and 12 months of age and adults. Gap detection thresholds were quite poor in infants. Effects of restricting the range of frequencies available for detecting gaps were qualitatively similar for infants and adults. (GLR)

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)

One experiment determined that the minimum angle at which infants can discriminate 2 sound presentations decreases substantially toward 48 weeks of age. In 3 succeeding experiments, infants aged 16, 20, and 28 weeks were able to discriminate sounds presented to each ear between 50 and 75 microseconds apart. (BC)

The encoding processes of poor and average readers were compared in a short-term memory task. Since poor readers have difficulty in integrating audiovisual input, it was hypothesized that this pattern may be due to inadequate acoustic encoding. The results did not support the hypothesis. (Author/CS)

The auditory temporal resolving power of young children was measured using an adaptive forced choice psycho-physical paradigm that was disguised as a video game. (PCB)

Matched groups of good and poor readers were administered a task that involved making same-different judgments for various combinations of auditory sequential, visual sequential, and visual spatial patterns. (Author)

The results fail to support the hypothesis that intersensory integration is the sole or even the primary developmental skill accounting for matching task improvement with increasing age. The hypothesis that retarded readers fail to develop skills in intersensory integration is also not supported. (Authors)
