Subjects made lateralization judgments involving dichotic sequences of 250-ms tones, which alternated in frequency between 400 and 800 Hz, such that when one ear received 400 Hz the other ear received 800 Hz, and vice versa. With sequences consisting of 20 dichotic tone pairs there was a strong tendency to lateralize each fused tonal percept toward the ear receiving the 800-Hz signal. In certai...

It may be difficult to determine whether a dichotic lag-click points the left or right when preceded by diotic lead-click. Previous research suggests that this loss of spatial information is most prominent at inter-click intervals (ICIs)  20 ms), suggesting different mechanisms underlying lateralization short versus long ICIs.

Four patients who preferred monaural as compared with binaural amplification were evaluated. For these patients, audiometric data, recognition performance on a dichotic digit task, and monaural and binaural hearing aid performance using four amplification strategies (National Acoustic Laboratories-Revised, a speech in noise algorithm, multiple-microphone arrays, and frequency modulated [FM]) ar...

background and aim: dichotic listening tests have been used to study right ear advantage (rea). fused dichotic rhymed word test (fdrwt), using rhymed words, is advantage­ous because of reducing the effect of attention on the test results. development of persian version of the fdrwt, and evaluation of its psychometric properties in normal children were the aims of the present study. methods: thi...

Musical enjoyment for cochlear implant (CI) recipients is often reported to be unsatisfactory. Our goal was to determine whether the musical experience of postlingually deafened adult CI recipients could be enriched by presenting the bass and treble clef parts of short polyphonic piano pieces separately to each ear (dichotic). Dichotic presentation should artificially enhance the lateralization...

This study explores whether there is an asymmetry with respect to the perceptual salience of an increase vs. a decrease of phonologically relevant features. A forced-choice discrimination experiment was conducted on stimulus pairs that included one member with unchanged phonetic features and the other with either increased or decreased degree of features (i.e., vowel nasality or VOT). The resul...

The present study will focus on occurrence of fully voiced, devoiced and elided high vowels in Japanese. High vowels elision in Japanese is supported by clear acoustic evidences, even though it is not globally accepted by scholars in the field. Elided vowels, hence, are considered here to have their own status. Moreover, this study is conceived in order to state differences and analogies among ...
