Tests whether aural discrimination is significantly better when visual-spatial stimuli are paired with melodic phrases. Results suggest that the use of visual clues paired with melodies is generally an effective aid to aural discrimination among fourth-grade subjects. Recommends further research on the use of different visual stimuli. (LS)

In a study of oddity performance, subjects were required to choose one distinct bimodal stimulus from a display that included other stimuli that did not differ from each other. Oddity performance was evaluated with both reversal assessments and assessments with new stimuli. The usefulness of bimodal training in oddity learning was demonstrated.…

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…

Explores the hypothesis that children identified as having phonological processing problems may have difficulty processing a different accent. Children with speech difficulties were compared with matched controls on four measures of auditory processing. Children were presented with stimuli in their own accent and in an unfamiliar accent…

Perceptual discrimination between speech sounds belonging to different phoneme categories is better than that between sounds falling within the same category. This property, known as ''categorical perception,'' is weaker in children affected by dyslexia. Categorical perception develops from the predispositions of newborns for discriminating all…

Absolute auditory thresholds, frequency resolution and temporal resolution develop with age. It is still discussed whether low-level auditory performance is of clinical significance--specifically, for delayed maturation of central auditory processing. Recently, five new auditory tasks were used to study the development of low-level auditory…

Time perception performance was systematically investigated in adolescents with and without attention-deficit/hyperactivity disorder (ADHD). Specifically, the effects of manipulating modality (auditory and visual) and length of duration (200 and 1000 ms) were examined. Forty-six adolescents with ADHD and 44 controls were administered four duration…

The present study investigates the contribution of general processing resources as well as other more specific factors to the life-span development of sensorimotor synchronization and its component processes. Within a synchronization tapping paradigm, a group of 286 participants, 6 to 88 years of age, were asked to synchronize finger taps with…

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…

An auditory perception study investigated the ability of 104 Japanese university students, all learners of English as a second language, to distinguish between five English voiceless fricatives in nonsense syllables. Stimuli consisted of 75 tokens presented in consonant-vowel, vowel-consonant-vowel, and vowel-consonant syllables spoken within a…

A study is described, the results of which indicate that mothers can recognize the cries of their own infants from tape-recorded cry samples with few instances of confusion, and that the sex of an unknown infant cannot be reliably identified using a simple auditory identification paradigm. (Author/RM)

A study comparing Black dialect-speaking children and white children in grades 3-6 on their ability to hear final consonant stops showed the Blacks significantly less able to hear these sounds than the whites. The results indicate a need for special help in reading instruction. (CK)

Research shows that information received by one brain hemisphere (e.g., auditory messages entering the right ear) is processed and transferred to the other, interpretation being a combination of right and left brain processing, with high intensity messages shifting control from the left to the right brain. If information is received by one…

Summarizing research activities in 1989, this is the fifteenth annual report of research on speech perception, analysis, synthesis, and recognition conducted in the Speech Research Laboratory of the Department of Psychology at Indiana University. The report contains the following 21 articles: "Perceptual Learning of Nonnative Speech…
