Electrophysiological and Psychophysical Measures of Temporal Pitch Sensitivity in Normal-hearing Listeners

alexandrossfakianakis shared this article with you from Inoreader Electrophysiological and Psychophysical Measures of Temporal Pitch Sensitivity in Normal-hearing Listeners via JARO - Journal of the Association for Research in Otolaryngology via MedWorm.com AbstractTo obtain combined behavioural and electrophysiological measures of pitch perception, we presented harmonic complexes, bandpass filtered to contain only high-numbered harmonics, to normal-hearing listeners. These stimuli resemble bandlimited pulse trains and convey pitch using a purely temporal code. A core set of conditions consisted of six stimuli with baseline pulse rates of 94, 188 and 280 pps, filtered into a HIGH (3365 –4755 Hz) or VHIGH (7800–10,800 Hz) region, alternating with a 36% higher pulse rate. Brainstem and cortical processing were measured using the frequency following response (FFR) and auditory change complex (ACC), respectively. Behavioural rate change difference limens (DLs) were measured by r equiring participants to discriminate between a stimulus that ... View on Web
