Children with reading disability and normal reading development were compared in their ability to discriminate native (English) and novel language (Mandarin) from nonlinguistic sounds. Children's preference for native versus novel language sounds and for disyllables containing dominant trochaic versus non-dominant iambic stress patterns was also…

Visual and auditory verbal learning using a selective reminding format was studied in a mixed clinical sample of children with autism spectrum disorder (ASD) (n = 42), attention-deficit hyperactivity disorder (n = 83), velocardiofacial syndrome (n = 17) and neurotypicals (n = 38) using the Test of Memory and Learning to (1) more thoroughly…

This study investigated the role of speech perception accuracy and speed in fluent word decoding of reading disabled (RD) children. A same-different phoneme discrimination task with natural speech tested the perception of single consonants and consonant clusters by young but persistent RD children. RD children were slower than chronological age…

This study tested if children with specific language impairment (SLI) or children with specific reading disability (SRD) have abnormal brain responses to sounds. We tested 6- to 12-year-old children with SLI (N = 19), children with SRD (N = 55), and age-matched controls (N = 36) for their passive auditory event-related potentials (ERPs) to tones,…

We describe the case of a child ("S") who was treated with radiation therapy at age 5 for a recurrent malignant brain tumor. Radiation successfully abolished the tumor but caused radiation-induced tissue necrosis, primarily affecting cerebral white matter. "S" was introduced to us at age 15 because of her profound dyslexia. We assessed cognitive…

Few studies have examined the ability of individuals with learning disabilities, in general, or with Down syndrome, specifically, to discriminate speech. The purpose of this study was compare the speech discrimination abilities of eight children with Down syndrome (aged 5.7 to 12.8 years) to seven nonverbal mental-age matched controls (aged 4.0 to…

A forward-gating procedure employing familiar monosyllabic words was used in auditory testing of age- and gender-matched elementary students with and without learning disabilities. Results indicate auditory closure skills were comparable between disabled and nondisabled subjects, but sensory discrimination problems may contribute significantly to…

Visual and auditory coding processes in learning-disabled students (SLDs, n=19) and control students (SCs, n=19) were examined. Analysis of decision latencies revealed that with initial task exposure, SLDs responded more slowly than SCs, but confusability patterns were similar. With practice, overall latencies became comparable, while…

Thirty learning disabled elementary grade students were given the Flowers Auditory Test of Selective Attention and the Goldman Fristoe Woodcock Auditory Selective Attention Test. Weak but significant correlations between the two tests of auditory selective attention suggested that the tests do not measure exactly the same constructs. (Author/DB)

A series of possible explanations for learning disabilities (LDS) couched in terms of information processing capabilities was tested by comparing the performance of LDS children on several types of information processing tasks with that of a control group. Subjects were 28 LDS children (10-11 years old) and 24 elementary school students of the…

Background: Claims that children with reading and oral language deficits have impaired perception of sequential sounds are usually based on psychophysical measures of auditory temporal processing (ATP) designed to characterise group performance. If we are to use these measures (e.g., the Tallal, 1980, Repetition Test) as the basis for intervention…

Debate continues over the hypothesis that children with language or literacy difficulties have a genuine auditory processing deficit. Several recent studies have reported deficits in frequency discrimination (FD), but it is unclear whether these are genuine perceptual impairments or reflective of the comorbid attentional problems that exist in…

A study examined central auditory processing ability of 15 children with attention-deficit hyperactivity disorder (ADHD), 15 children with ADHD and learning disabilities (LD), and 15 controls. Results indicated lower central-auditory-processing ability and significant correlations between reading and ADHD and reading and…

Evaluation of 54 mentally retarded pupils, aged 10 to 13, in 1979 and comparison with six samples of mentally normal pupils collected during the last two decades confirm that prevalence of additional problems among mentally retarded pupils is greater as compared to mentally normal pupils with respect to nine variables. (NEC)

Twenty reading-disabled, 10 math-disabled, and 25 control-group college students were assessed on a battery of psychophysical tasks that included 5 tests of temporal processing. Findings suggest that poor temporal processing is neither a necessary nor a sufficient cause of reading disability but that there is a modest association between the two…
