Dichotic listening CV lateralization and developmental dyslexia.
The present study was carried out on a sample of 125 right-handed boys who are described as follows: 50 boys with dyslexia, 50 controls of a similar age, and 25 controls according to reading level. Using an objective procedure based on regression, we selected three subgroups from among the poor readers: children with difficulties in the lexical pathway (surface dyslexics), children with difficu...
متن کاملTrading of intensity and interaural coherence in dichotic pitch stimuli.
When a signal is added to noise in the NoSπ binaural configuration, a reduction in interaural coherence, ρ, occurs at the signal frequency and increases in tone intensity decrease ρ. Corresponding manipulations of ρ result in the perception of a phantom signal which increases in loudness as ρ decreases [Culling et al. (2001). J. Acoust. Soc. Am. 110, 1020-1029]. In the present study, a narrow s...
متن کاملPresurgical language lateralization assessment by fMRI and dichotic listening of pediatric patients with intractable epilepsy
OBJECTIVE The aim of this study was to evaluate the clinical use of a method to assess hemispheric language dominance in pediatric candidates for epilepsy surgery. The method is designed for patients but has previously been evaluated with healthy children. METHODS Nineteen patients, 8-18 years old, with intractable epilepsy and candidates for epilepsy surgery were assessed. The assessment con...
متن کاملLateralization by frequency for repeating sequences of dichotic 400- and 800-Hz tones.
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...
متن کاملLateralization of dichotic speech stimuli is based on specific auditory pathway interactions: neuromagnetic evidence.
Dichotic listening (DL) is a neuropsychological technique for the study of functional laterality. Based on behavioral patient studies, the "structural theory" states that lateralization of the auditory input during DL is allowed by an inhibition of the ipsilateral pathways. We aimed here at extending this theory to provide a neurophysiological basis of verbal DL. We investigated the magnetic re...
