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...

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: 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...

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...

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 ...

The new compact disc from the Department of Veterans Affairs, Tonal and Speech Materials for Auditory, Perceptual Assessment, Disc 2.0 (1998), contains two lists of randomly interleaved 1-, 2-, and 3-pair dichotic digits. Two experiments are reported, in which the effects of low-pass filtering and inter-digit interval on dichotic digit recognition were investigated in adult listeners with norma...

PURPOSE To compare the performances of children with dyslexia and a control group in behavioral tests of (Central) Auditory Processing and Long Latency Auditory Evoked Potentials (P300). METHODS Participants were 22 individuals with dyslexia (study group) and 16 individuals with typical development (control group). All individuals underwent behavioral and electrophysiological assessment of (C...

Introduction Elderly individuals with bilateral hearing loss often do not use hearing aids in both ears. Because of this, dichotic tests to assess hearing in this group may help identify peculiar degenerative processes of aging and hearing aid selection. Objective To evaluate dichotic hearing for a group of elderly hearing aid users who did not adapt to using binaural devices and to verify the ...
