Auditory and visual recognition were studied in subjects ranging in age from 10 to 60 years. In comparison with perceptual and response factors, memory scanning time is relatively insensitive to age differences, and auditory recognition involves the use of a pre-linguistic memory system insensitive to age differences.

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…

This study tested the hypothesis that there is a developmental shift in the perceptual weighting of acoustic parameters that results from experience with a native language. Comparison of 17 3-year olds and 16 adults found that age-related differences in auditory sensitivity did not fully account for age-related differences in perceptual weighting…

Adolescents with and without learning disabilities (14, 16, and 18 years old) were tested to determine whether they differed in auditory, visual, and/or multisensory social perception abilities. The adolescents with learning disabilities at all age levels were not as adept at understanding nonverbal social information regardless of whether it was…

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)

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)

Assessed development of infants' sensitivity to two nested amodal temporal relations in audible and visible events. Found that sensitivity to synchrony was present by 4 weeks, remaining stable across age. Sensitivity to composition emerged by 7 weeks, increasing dramatically with age. Noted pattern of increasing specificity in perception…

In this study, younger and older adults heard either just word onsets, word onsets followed by white noise indicating word duration, or word onsets followed by signals indicating word prosody. Older adults required longer stimulus durations for word recognition with hearing sensitivity a significant factor. Word recognition was facilitated equally…

Auditory perception of English minimal pairs was tested with or without noise background. Each subject was interviewed after the test to collect information regarding their early experience on learning English as a foreign language. This study was designed to examine the differential effects of learning English at three age-starting points and two…

The paper examines ways in which language complexity of the stimulus and language ability of the receivers may influence learning via television for hearing impaired and hearing children. Research is reviewed on the impact of language abstraction on learning from television, and findings from paired associate learning trials are cited to suggest…

The article presents normative data for the Spanish version of the "Test for Auditory Comprehension of Language" using data based on the speech of 60 Mexican children in three age groups from two to nine years. Half the children were low socioeconomic monolingual, and half were high socioeconomic bilingual. (Author/DB)

Because young children have poorer auditory temporal resolution than older children, a study measured the auditory filters of two 6-year-olds, two 10-year-olds, and two adults by having them detect a 400-ms sinusoid centered in a spectral notch in a band of noise. (HOD)

Findings suggested that a deficit in auditory memory rather than cross-modal perception appears to be a factor in poor reading comprehension. (Author/DLS)
