This paper presents a dichotic listening experiment on the perception of Mandarin tones under clean and noisy conditions. We examine the enhancing role of noise on the lateralization patterns of tones. We discover that the lateralization patterns of different tones are inconsistent: the perception of tone 1 exhibits a left ear advantage, while that of tone 2 or tone 4 has a right ear advantage....

Normal and dyslexic right-handed children were assessed with three dichotic listening tests, the Dichotic Digits test, the Competing Words subtest of the SCAN, and the Dichotic Consonant-Vowel test. Performance was measured as both number and percentage of correct responses in the right and left ears. Laterality was defined as a simple difference in percentage between the two ears. Differences ...

Contribution of the left ear stimulus to dichotic listening performance following commissurotomy was studied in five patients. In two tasks, subjects were asked to identify in writing both members of a pair of competing stimuli, either digits or CV syllables. A third task required subjects to integrate high and low frequency components of a single word presented dichotically. Left ear performan...

The study examined the relationship between perinatal stress and decreased right handedness and decreased left cerebral dominance for speech with 215 children born prematurely, followed from birth, and tested at age 5. Results indicated that neither hand preference nor hand performance correlated with degree of perinatal stress and that eye preference was associated with perinatal stress though...

In this article we review research in our laboratory on auditory hallucinations using behavioral and MRI measure. The review consists of both previously published and new data that for the first time is presented together in a cohesive way. Auditory hallucinations are among the most common symptoms in schizophrenia, affecting more than 70% of the patients. We here advance the hypothesis that au...

We examined the effect of perceptual training on a well-established hemispheric asymmetry in speech processing. Eighteen listeners were trained to use a within-category difference in voice onset time (VOT) to cue talker identity. Successful learners (n=8) showed faster response times for stimuli presented only to the left ear than for those presented only to the right. The development of a left...

Dichotic listening was evaluated using monosyllabic word pairs that differed in lexical difficulty as defined by the Neighborhood Activation Model of spoken word recognition. Four combinations of lexically EASY and lexically HARD words were evaluated (same pair: EASY-EASY, HARD-HARD; or mixed pair: EASY-HARD, HARD-EASY) in young adult listeners with normal hearing and older adult listeners with...
