THE AUSTRALIAN AND NEW ZEALAND JOURNAL OF AUDIOLOGY VOLUME 28 NUMBER 2 NOVEMBER 2006 pp. 122–136Abstract: Cortical auditory evoked potentials (CAEP) were recorded from ten normal-hearing infants, aged 3 to
7 months, using the natural speech segments /m/ and /t/. The aim was to investigate the effect of selected
stimulus durations and inter-stimulus intervals (ISIs) on infant responses. In the first experiment, various
stimulus durations were used but the ISI was fixed.
Results showed no significant difference in the latency of the first positive peak (P1) with changes in stimulus duration, but there was a minor increase in amplitude when duration increased from short to medium length.
