Hemispheric asymmetries depend on the phonetic feature: A dichotic study of place of articulation and voicing in French stops
We found a decrease in REA when the initial stop consonants of two simultaneous French CVC words differed in voicing rather than place of articulation (Experiment 1). This result suggests that the right hemisphere (RH) is more involved in voicing than in place processing. The voiceless-voiced contra...
[Validation of a new test for measuring of tonal and verbal skills on dichotic listening].
[Dichotic digit test. Case].
We present a case of a 71-year-old female patient with sensorineural hearing loss and fitted with bilateral hearing aids. The patient complained of scant benefit from the hearing aid fitting with difficulties in understanding speech with background noise. The otolaryngology examination was normal. A...
Discrimination of the spectral structures of sound signals on the background of interference.
Presentation of test signals consisting of sounds with rippled spectra allowed measurements of the frequency-resolving ability (FRA) of hearing to be performed in humans without using frequency-dependent masking techniques. This allowed studies of changes in FRA in the presence of noise interference...
Recognition of one-, two-, and three-pair dichotic digits under free and directed recall.
A one-, two-, and three-pair dichotic digit test was administered to 180 subjects (20-79 years) with varying degrees of hearing sensitivity. The test was carried out under free- and directed-recall response conditions. The results indicated that recognition performance decreased as a function of inc...
Influence of unilateral deafness on auditory evoked magnetic field.
We examined patients with unilateral deafness of various durations. Auditory evoked magnetic fields (AEF) were recorded using a whole-head neuromagnetometer. In patients who had unilateral deafness for more than 3 weeks, the average N100m latency in the ipsilateral hemisphere did not differ from tha...
Effect of trial-by-trial variation in center frequency on detection of interaural temporal and intensitive differences in bands of noise.
Sensitivity to interaural temporal disparities (ITDs) and interaural intensitive disparities (IIDs) was measured as a function of duration in conditions where the center frequency (CF) of the stimuli was constant and, separately, in conditions where the CF of the stimuli was varied on a trial-by-tri...
Possible subtypes of affective disorder suggested by differences in cerebral laterality and testosterone. A preliminary report.
Two language-related dichotic listening tests of cerebral laterality were used to divide a group of 18 hospitalized patients with affective disorder into two subgroups of nine. The groups proved to differ in serum testosterone levels at the time of admission and in mean serum testosterone levels thr...
Processing of timbre and rhythm in musicians and non-musicians.
Expert musicians and non-musicians of similar educational and social class background were compared in two experiments involving perception of timbre and rhythm. In Experiment 1 where dichotic monitoring for the sound of the violin was required, there was a practice effect but no ear...
Differential effects of awakening from REM and NONREM sleep on dichotic listening performance as a function of handedness.
These results are interpreted in view of the data suggesting REM-related right hemisphere activation and the role of the right hemisphere in regulating bihemispheric arousal levels....
