“…Poor scores and reversed ear advantages on the free recall version of the digits test were consistent with previous results that uncontrolled attentional factors tax verbal processing efficiency in all listeners and potentially cause greater reductions in left ear performance among dyslexic children (Lamm & Epstein, 1997;Obrzut, Conrad, Bryden, & Boliek, 1988). Significant group differences for left ear scores with digits in this study support this notion that the task may have placed greater demands on dyslexic listeners for responses in both ears, but the effects were greater for the left ear.…”

“…The degree of a listener's ear advantage is related to maturation and related increases in verbal processing efficiency (Bellis, 2003). Verbal processing is taxed with stimuli such as CVs that differ only in initial phoneme (Berlin, Hughes, Lowe-Bell, & Berlin, 1973) or an open set of single syllable words (Keith, 1986;Lamm & Epstein, 1997), resulting in larger ear advantages of as much as 15%. Because digits are a closed set of highly familiar words, verbal processing requirements are lower than with CVs or words and ear advantages typically drop to as little as 2% by age 11 (Bellis, 2003;Harper & Kraft, 1994).…”

Several auditory processing deficits have been reported in children with dyslexia. In order to assess for the presence of a binaural integration type of auditory processing deficit, dichotic listening tests with digits, words and consonant-vowel (CV) pairs were administered to two groups of right-handed 11-year-old children, one group diagnosed with developmental dyslexia and an age-matched control group. Dyslexic children performed more poorly than controls from their left ears when listening to digits and words and from their right ears when listening to CVs. Direction of ear advantage varied across individuals in both groups when tested with digits and CVs, but ear advantage was stable with words. Several factors that may have contributed to inconsistencies in direction of ear advantage are discussed. When the children were tested in a directed response mode, degree of ear advantage differed significantly between groups with both words and digits. More dyslexic than control children demonstrated clinically significant reductions in dichotic listening performance, but no uniform pattern of deficit emerged. Only the double correct score and the left ear score with CV pairs were predictive of word recognition performance in dyslexic children. Binaural integration deficits are present in some children with dyslexia. Auditory processing disorder assessment may help delineate factors that underlie or are associated with reading impairment in this population.

“…In dyslexia (Lamm & Epstein, 1997;Helland & Asbjornsen, 2001;Asjornsen et al, 2003) and in auditory processing disorder (Musiek, 1999) there has been reported a significantly reduced left ear performance and this has been attributed to poor interhemispheric transfer of auditory information. Most studies are testing children with dyslexia, and they report clinically significant reductions in dichotic listening performance (Maerlender et al, 2004 as well as changes in ear direction when both the free recall procedure and the directed response procedure were used.…”

One of the widely used tests to evaluate functional asymmetry of cerebral hemispheres is the dichotic listening test with the usually prevailing right ear advantage. The current study aims at assessing hemispheric laterality in an adult sample of individuals with dyslexia, with auditory processing disorder (APD), and adults experiencing comorbidity of the two mentioned disorders against a control group with normal hearing and absence of learning disabilities. Results exhibit a right hemispheric dominance for the control and APD group, a left hemispheric dominance for the group diagnosed with both dyslexia and APD, and absence of dominance for the dyslexia group. Assessment of laterality was repeatable and produced stable results, indicating a true deficit. A component of auditory processing, specifically the auditory performance in competing acoustic signals, seems to be deficient in all three groups, and laterality of hemispheric functions influenced at least for auditory-language stimuli in the two of the three groups, one being adults with dyslexia and the other being adults with comorbidity of dyslexia and APD.

“…In the initial analysis of the digits dichotic test results, Lamm and Epstein (1997) found that performance improvements with age were mainly expressed by an increase in overall performance per trial (i.e. overall number of correct responses) together with a decrease in the absolute ear difference in correct responses.…”

“…I n a recent study (Lamm and Epstein, 1997) we reported the performance of verbal dichotic tests in children before their enrolment in school and a year later at the end of their first grade. The same digit and word dichotic tests, each requiring free recall of stimuli, were administered in both testing sessions.…”

Kindergarten dichotic listening as a predictor of first-grade reading achievement

In this study we examined the contribution of reading acquisition to changes in dichotic listening test performance by young children between kindergarten and the end of grade 1. We found that longitudinal changes in the performance level of both dichotic tests used in this study (a digits test and a words test) did not correlate with school achievement in reading. On the other hand, kindergarten performance in the words dichotic test was a reliable predictor of failure in reading acquisition a year later. Moreover, most subjects who experienced difficulties in learning to read and in the words dichotic test also failed in a kindergarten test requiring the matching of syllable combinations with arbitrary letter-like symbols. It was thus hypothesized that both kindergarten tests were good predictors of reading difficulties owing to the implicit task of serial handling of simultaneously activated syllables.
