Discusses (1) the process of early language development, giving specific attention to problematic aspects of a vocabulary for audition; (2) elicitation and instruction tasks used in the study of language acquisition; and (3) an investigation designed to compare language acquisition for dimensions of visual, spatial, and tactual perception with…

The Illinois Test of Psycholinguistic Abilities was administered to 166 second graders who were classifed as auditory or visual learners on the basis of discrepancies in individual test profiles. (Author)

To determine whether the auditory difficulties of learning disabled (LD) children are characterized by deficiencies in processing especially rapid or especially slow speech, the effect of various rates of compressed and expanded sentences on the repetition performance of 20 LD and normal children (ages 8 to 11 years) was investigated. (Author/DLS)

Results of a study with 52 dyslexic children and 52 normal readers show that reading acceleration through computer-controlled reading rates improves reading performance in both groups, but auditory masking by playing a song is beneficial only to the dyslexic children. Implications are discussed in terms of phonological processing. (SLD)

Children (ages 6-7 and ages 8-9) and adults participated in real-word and nonword lexical decision tasks and an auditory-vocal reaction time task. Response times on all tasks decreased with age. However, age-related differences on the real-word lexical decision task disappeared when differences in auditory-vocal reaction times were taken into…

Two experiments used phoneme counting tasks to investigate the foundations of phonemic awareness. Found that first graders and college students had some ability to distinguish between monophthongs (as in "he") and diphthongs (as in "how"), and they tended to count fewer "sounds" for syllables ending with the more…

The short-term verbal memory performance of 19 children and young adults with Down syndrome (DS) was contrasted with that of two control groups. Results confirm the expected verbal short-term memory deficit in DS subjects and suggest that this deficit is specific to memory for verbal information and is not primarily caused by auditory or…

Based on findings from the Health Examination Survey of 1963-65, estimates were reported on the prevalence of abnormal conditions of the ear, nose, and throat and the relation of these various abnormalities to hearing sensitivity of noninstitutionalized children aged 6 to 11 years old in the United States. A total of 7,119 children participated in…

Studied the ability of 8- and 11-year olds, and college-age subjects, to allocate attention rapidly. Older subjects were better able to reallocate attention. The developmental change in the reallocation of attention appears to be continuous and quantitative. Improvement is linked to the ability to use active attentional strategies. (Author/GH)

The ability to recall correctly ordered information was examined using two auditory tasks (narrative recall and digit span) and a nonverbal, visual task, with 47 individuals with Down's syndrome (ages 5 to 20) and 47 mentally aged-matched children. Although Down's syndrome subjects recalled less information than controls, no differences in the…

Studied whether patterns of developmental progression in reality monitoring were present in visual and auditory modalities and the role of cross-modal imagery in reality-monitoring tasks. Found scores revealed evidence of developmental progression in both auditory and visual source-monitoring tasks, but no effect of cross-modal imagery. (Author)

A double-blind, placebo-controlled study examined effects of methylphenidate (Ritalin) on auditory processing in 32 children with both attention deficit hyperactivity disorder and central auditory processing (CAP) disorder. Analyses revealed that Ritalin did not have a significant effect on any of the central auditory processing measures, although…
