This study investigated hemispheric lateralization of Mandarin tone. Four groups of listeners were examined: native Mandarin listeners, English–Mandarin bilinguals, Norwegian listeners with experience with Norwegian tone, and American listeners with no tone experience. Tone pairs were dichotically presented and listeners identified which tone they heard in each ear. For the Mandarin listeners, ...

Laterality in the perception of non-stationary aspects of musical timbre was investigated in 54 right-handed non-musicians. Timbre differences were produced by altering the amplitude envelope of a steady-state complex tone. Two single-choice tests with attention directed to one ear were used--a dichotic test and a monaural test with contralateral white noise. Dependent variables were reaction t...

Previous research has demonstrated that psychopaths exhibit abnormal language lateralization, and it has been proposed that psychopaths may be characterized by abnormal processing asymmetries in other domains as well [Hare, (1998). Psychopathy, affect, and behavior. In D. J. Cooke, A. E. Forth, & R. D. Hare (Eds.), Psychopathy: theory, research and implications for society (pp. 105–137). Nether...

Ear advantages in dichotic listening are generally held to reflect greater involvement of the hemisphere contralateral to the preferred ear. Rationales for this view rely on the assumption that, when information arriving at the two ears is treated as a single complex signal, an advantage to a component of this signal based on ear of input will not interact with an advantage based on some other ...

Two dichotic listening tests, one a verbal consonant-vowel identification task, the other a musical chord recognition task, were administered to 32 women at two points during the menstrual cycle, menses (when oestrogen is low) and the midluteal phase (when oestrogen is high), in a counterbalanced repeated measures design. The degree of asymmetry changed across the cycle for both syllables and m...

Dichotic word recognition was evaluated in free-recall, directed-attention right, and directed-attention left response conditions. All participants were right-handed and included a group of young adults with normal hearing and two groups of older adults with sensorineural hearing loss. Dichotic word recognition performance was best for young adults and decreased for each older group. A right-ea...
