Dichotic Listening Tests 171 articles
Cross-sectional study of differences in speech understanding between users and nonusers of estrogen replacement therapy.
The purpose of this study was to examine whether women who use estrogen replacement therapy (ERT) differ from women not using ERT on several measures of speech understanding. Participants (n = 38, 60 to 74 years) completed a battery of tests including pure-tone audiometry, the Dichotic Sentence Iden...
[Analysis of acoustic and vocal processes in children with Gilles de la Tourette's disease using dichotic listening tests].
A study was made of the specificity of interhemispheric interaction in realization of acoustic and vocal processes in children with Gilles de la Tourette's syndrome. 27 patients aged 8 to 12 years were selected for the studies. The research method used was dichotic listening. There were material dif...
Null hypothesis disrespect in neuropsychology: dangers of alpha and beta errors.
These results are also discussed in the broader context of the necessity for investigators in neuropsychology to differentiate between the statistical and clinical significance of research findings; and to develop a more positive attitude toward the design, execution, and publication of replication...
Release from first-formant masking in presbyacusis.
Using synthetic vowels, the effects of first-formant masking on discrimination of the presence of a transition in the second formant were measured under conditions of first-formant attenuation and dichotic presentation. The subjects were 26 listeners between the ages of 61 and 91 with borderline to...
Assessment and remediation of an auditory processing disorder associated with head trauma.
This case study involves a 41-year-old female who had sustained a mild traumatic brain injury during a horseback riding accident. The patient was seen for medical and neuropsychological testing following this incident and was referred to a speech-language pathologist for rehabilitative services. At...
[Specificity of hemispheric asymmetry in prosody perception in schizophrenia and in the norm].
ERP indicators of disturbed attention in mild closed head injury: a frontal lobe syndrome?
The purpose of the study was to examine the hypothesis that distractibility is a fundamental characteristic of mild closed head injury (MHI). The claim that cognitive symptoms in MHI are due to a mild type of frontotemporal injury was also investigated. Cognitive event-related potentials (ERPs), acc...
Speech enhancement based on physiological and psychoacoustical models of modulation perception and binaural interaction.
A novel approach for analyzing and filtering speech is described and evaluated which utilizes the "modulation spectrogram," i.e., the two-dimensional representation of modulation frequencies versus center frequency as a function of time. This approach is based on physiological findings of a tonotopi...
Auditory attention in the congenitally blind: where, when and what gets reorganized?
Functional reorganization of auditory attention was studied in 12 congenitally blind subjects and 12 controls using high-density event-related potentials during a highly focused dichotic listening task. Reaction times for the attend-ear intensity-deviant targets were markedly faster for the blind. B...
Relationship between auditory intensity discrimination in noise and olivocochlear efferent system activity in humans.
These results support the hypothesis that MOCS functioning plays a role in intensity discrimination in dichotic noise in humans....
