Cross-modal aftereffects of visuo-manual prism adaptation: Transfer to auditory divided attention in healthy subjects.
2021
OBJECTIVE Prism adaptation was shown to modify auditory perception. Using a dichotic listening task, which assesses auditory divided attention, benefits of a rightward prism adaptation were demonstrated in neglect patients (i.e., a syndrome following right hemisphere brain damage) by reducing their left auditory extinction. It is currently unknown whether prism adaptation affects auditory divided attention in healthy subjects. In the present study, we investigated the aftereffects of prism adaptation on dichotic listening. METHOD A sample of 47 young adults performed a dichotic listening task, in which pairs of words were presented with two words sounded simultaneously, one in each ear. Thr…
A comparison of the effects for sustained versus shifted attention on dichotic listening performance.
2009
We measured the effect of two types of directed attention instructions, sustained by a verbal cue or shifted by a tone cue with different time intervals (150, 450, and 750 ms), on a consonant-vowel dichotic listening (C-V DL) test for a large group of right- and left-handed participants of both sexes. An increasing of the hits and a decreasing of the intrusions from the baseline DL test scores was evident for both types of attentional manipulations, with no differences regarding sex or handedness. Increasing the time from 150 to 450 ms benefited the focusing of attention but this advantage was markedly attenuated at the longer 750-ms interval. The improving effect was seen for the hits of b…
Dichotic listening: elimination of the right ear advantage under a dual task procedure.
1997
The aim of this article is to investigate the attentional effect on the dichotic listening (DL) performance when doing a simultaneous right hemisphere task. A group of 30 right-handed male participants had a standard DL test followed by a dual task procedure that consisted of a manipulospatial discrimination through the left hand and performed while doing the DL test. Participants showed the typical right ear advantage (REA), which lost its significance when they were confronted with the dual task, presumably due to the manipulospatial performance. The elimination of the REA was mainly due to facilitation of the left ear responses. Results are discussed in terms of Kinsbourne's model and ot…
Abnormal Linguistic Lateralization and Sensory Processing in High Functioning Children with Autism Spectrum Conditions
2014
Brain lateralization for language in high-functioning children with autism spectrum conditions (ASC) and sensory processing were explored as a part of a neuropsychological profile. A dichotic listening test and the Luria laterality subtest were administered to all participants (including controls) and the sensory profile test only to the ASC group. The usual right ear advantage was not exhibited by children with ASC and anomalies in auditory filtering were found. The sensory profile of 60% of the sample was characterized by hypersensitivity to auditory stimuli, hyposensitivity to vestibular information, high emotional reactions to sensory experiences, poor psychosocial coping strategies, hi…
