background and aim: hearing impaired students experience binaural hearing like normal peers and school age is challenging time for using dichotic listening. lack of research was found on relationship of persian hearing impair­ed children with central auditory processing (cap). one of the aims of this study was a comparison between persian dichotic digit test (ddt) score in children with mild an...

Single and double dichotic digit tests in Malay language were developed and standardized as an initial attempt to incorporate tests of auditory processing within the scope of audiology practice in Malaysia. Normative data under free recall, directed right-ear first, and directed left-ear first listening conditions were determined using 120 Malay children between the ages of 6 and 11 years old w...

background and aim: the double dichotic digit test (ddt) is a simple test for assessing and screening auditory processing system. the purpose of this study was to develope a double ddt, in persian language and find its basic norm values in girls aged 7 to 11 years. methods: the persian version of double ddt is composed of 3 different 25 numerical lists. numbers in each list were recorded dichot...

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...

background and aim: dichotic listening tests have been used to study right ear advantage (rea). fused dichotic rhymed word test (fdrwt), using rhymed words, is advantage­ous because of reducing the effect of attention on the test results. development of persian version of the fdrwt, and evaluation of its psychometric properties in normal children were the aims of the present study. methods: thi...

background and aim: dichotic listening evaluation is one of the most common behavioral procedures for assessing the cerebral dominance of language and is considered as the main component of the auditory processing test battery in children and adults. the randomized dichotic digits test (rddt) has two lists of randomly distributed one-, two-, and three-digit items. this research was performed fo...

BACKGROUND Chess is a game that involves many aspects of high level cognition such as memory, attention, focus and problem solving. Long term practice of chess can improve cognition performances and behavioral skills. Auditory memory, as a kind of memory, can be influenced by strengthening processes following long term chess playing like other behavioral skills because of common processing path...

We hypothesized that the Digit Span (DS) subtest and component tasks (Wechsler, 1991) would show strong relationships with a dichotic listening test (Musiek, 1983). In two sets of archival clinical data (N = 74 and N = 51) we demonstrated that: (a) individuals with central auditory deficits had lower DS scores, F(1, 72) = 7.34, p = .008; eta2 = .09; and (b) left-ear dichotic deficits impacted f...

BACKGROUND Verbally based dichotic-listening experiments and reproduction-mediated response-selection strategies have been used for over four decades to study perceptual/cognitive aspects of auditory information processing and make inferences about hemispheric asymmetries and language lateralization in the brain. Test procedures using dichotic digits have also been used to assess for disorders ...
