Introduction: The aim of this case report was to investigate the relationship between sleep disorders and audio vestibular symptoms.   Case Report: A case of undiagnosed sleep disorder, presenting as a temporary auditory processing difficulty, is presented. The disorder was initially treated as sudden deafness with dizziness. A 23-year-old male patient complained of acute hearing disturbance de...

Previous research has demonstrated that psychopaths exhibit abnormal language lateralization, and it has been proposed that psychopaths may be characterized by abnormal processing asymmetries in other domains as well [Hare, (1998). Psychopathy, affect, and behavior. In D. J. Cooke, A. E. Forth, & R. D. Hare (Eds.), Psychopathy: theory, research and implications for society (pp. 105–137). Nether...

There are numerous recent reports of low-level temporal asymmetries favouring the left hemisphere, and increasing speculation that the left hemisphere's relative superiority at linguistic processing may be related to these asymmetries. The present study sought to test this claim by assessing linguistic lateralization with the Fused Dichotic Words Test and visual temporal asymmetries with a late...

The neural architecture of the corpus callosum shows pronounced inter-individual differences. These differences are thought to affect timing of interhemispheric interactions and, in turn, functional hemispheric asymmetries. The present study aimed at elucidating the neuronal mechanisms underlying this relationship. To this end, we used a combined DTI and EEG study design. In 103 right-handed an...

background and aim: dichotic digit test (ddt) is a valid neuropsychological tool for determining the dominant hemisphere in verbal processing; therefore, the main goal of this research was designing and investigating the psychometric properties of ddt in a sample of iranian children and then measuring its concurrent validity using the n-back task. methods: the present study was a descriptive an...

Earlier investigations have shown that spectral splitting of speech signal helps in reducing the effect of spectral masking for persons with moderate bilateral sensorineural hearing loss. In spectral splitting, the speech signal is filtered using a pair of linear phase FIR comb filters with complementary magnitude responses for binaural dichotic presentation. The filter responses should be such...

OBJECTIVE To investigate the clinical usefulness of the dichotic single-frequency auditory steady-state response (ASSR) for estimation of behavioral thresholds in children with severe to profound congenital sensorineural hearing loss. DESIGN A comparative experimental research design was selected to compare behavioral and ASSR thresholds for the sample. Behavioral pure-tone audiometry served ...

Quality of hearing has been severely impacted due to signal losses occurs in the human inner ear explicitly region cochlea. Loudness recruitment, degraded frequency selectivity and auditory masking are major outward effects losses. Splitting signals into bands presenting dichotically both ears became a comprehensive solution reduce However, these methods divide input fix number bands, this limi...

Dichotic listening (DL) procedures are commonly employed in the evaluation of auditory processing in children. Review of the various clinical tests reveals considerable diversity in both the signals employed and their mode of administration. The extent to which other non auditory-specific factors influence the test outcome is often difficult to determine. Individual differences in memory, atten...
