dichotic listening test การใช้

• Dichotic listening tests can also be used as lateralized speech assessment task.
• During his experimentation, Broadbent made use of the dichotic listening test.
• Usually dichotic listening tests show a right-ear advantage for speech sounds.
• The " Dichotic Fused Words Test " ( DFWT ) is a modified version of the basic dichotic listening test.
• The manipulation of voice onset time ( VOT ) during dichotic listening tests have given many insights regarding brain function.
• Dichotic listening tests can be used to measure the efficacy of the attentional control of cochlear inhibition and the inter-hemispheric transfer of auditory information.
• Dichotic listening tests typically involve two different auditory stimuli ( usually speech ) presented simultaneously, one to each ear, using a set of headphones.
• Some data gathered from dichotic listening test experiments suggests that there is possibly a small-population sex difference in perceptual and auditory asymmetries and language laterality.
• The application of the dichotic listening test helped to further the beliefs that preserved left hemisphere processing is a product of paranoid schizophrenia, and in contrast, that the left hemisphere's lack of activity is a symptom of undifferentiated schizophrenia.
• On non-language dichotic listening tests she showed a slight preference for identifying non-language sounds in her left ear, which was typical for a right-handed person and helped rule out the possibility of her brain only being reversed in dominance for language.
• Audiometry tests confirmed that she had regular hearing in both ears, but on a series of dichotic listening tests Bellugi and Klima found that she identified language sounds with 100 % accuracy in her left ear while correctly answering at only a chance level in her right ear.
• The manipulation of voice onset time ( VOT ) during dichotic listening tests have given many insights regarding brain function . first reported that in healthy adults SL pairs elicit the largest right ear advantage ( REA ) while, in fact, LS pairs elicit a significant left ear advantage ( LEA ).
• A study conducted involving the dichotic listening test, with emphasis on subtypes of schizophrenia ( particularly paranoid and undifferentiated ), demonstrated that paranoid schizophrenics have the largest left hemisphere advantage-with undifferentiated schizophrenics ( where psychotic symptoms are present but the criteria for paranoid, disorganized, or catatonic types have not been met ) having the smallest.
