The ovarian hormones fluctuate during the menstrual cycle in women. Such fluctuation of sex hormones, in particular estrogen, is believed to affect the central conduction time in auditory function as well as the language lateralization in cognitive function. However, findings are inconsistent. The underlying mechanisms are also unclear. This paper examined if there was any relation between the ...

UNLABELLED Auditory processing disorder is a clinical entity that may be associated with several neuropathological disorders - learning disabilities among them. AIM To characterize and compare the performance of students with and without learning disabilities in speech tests with and without background noise, dichotic listening tests, alternating dissyllable test. MATERIALS AND METHODS 40 s...

A prior study (Bruder, G.E., Stewart, J.W., Mercier, M.A., Agosti, V., Leite, P., Donovan, S., Quitkin, F.M., 1997. Outcome of cognitive-behavioral therapy for depression: relation of hemispheric dominance for verbal processing. Journal of Abnormal Psychology 106, 138-144.) found left hemisphere advantage for verbal dichotic listening was predictive of clinical response to cognitive behavioral ...

Dichotic listening procedures have been used to assess cerebral lateralization in normal subjects. One particularly useful technique is the use of stimuli that fuse into a single percept. Although this procedure has many advantages over other dichotic listening methods, it is particularly susceptible to stimulus dominance, which acts as noise in a subject's response data, thus reducing the powe...

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...

A one-, two-, and three-pair dichotic digit test was administered to 180 subjects (20-79 years) with varying degrees of hearing sensitivity. The test was carried out under free- and directed-recall response conditions. The results indicated that recognition performance decreased as a function of increasing age. Statistical analysis using analysis of covariance indicated that differences in perf...

background: cognitive impairment profoundly influences on older adults’ activities and quality of life. therefore, optimizing and remediating age-associated cognitive decline have great importance. objectives: to evaluate the effect of 8 weeks (3 day /week) computer based brain training on cognitive performance in old women with mild cognitive impairment (mci). materials and methods: this rando...

In this study we examined the interaction of fundamental frequency (Fo) differences and binaural separation cues on the identification accuracy and judgments of the relative pitches of concurrent vowel pairs. On each pitch ranking trial listeners were told which vowels were presented and were asked simply to indicate which vowel was on the higher pitch. The first vowel had an FO near 140 Hz and...
