Three experiments investigated 4-, 6-, and 8-month-olds' perception of the audible, visible, and combined attributes of bimodally specified syllables. Results suggested that at 4 months, infants attended primarily to the featural information, at 6 months primarily to the asynchrony, and at 8 months to both features independently. (Author/KB)

Elementary school children in three grade groups (Grades K/1, 3, and 5/6) completed either the auditory or the visual 1/9 vigilance task from the Gordon Diagnostic System (GDS) as well as subtests from the Wechsler Intelligence Scale for Children--Third Edition and auditory or visual processing subtests from the Woodcock-Johnson Tests of Cognitive…

Purpose: The temporal offset of auditory saltation is thought to be reflective of the limits of temporal resolution, and has recently been used to compare dyslexic and control adults and children, with mixed results (R. Hari & P. Kiesila, 1996; M. Kronbichler, F. Hutzler, & H. Wimmer, 2002). This study sought to document and understand normative…

Investigation of the perception and production of English voiceless fricatives in normally developing monolingual 3- to 5-year-olds (N=12) partially supported the hypothesis that certain sound substitutions by older children are perceptually based substitutions, typified by poor discrimination, while others are phonetic substitutions--phonemic…

This annual report presents several articles related to the work of the Clinical Center for Child Development at Hokkaido University in Sapporo, Japan. The articles are: (1) "Joint Attention as a System Property of the Infant-Caregiver Interaction System"(Tsuneda Miho and Shing-Jen Chen); (2) "Age-Related Change in Japanese Maternal…

Subjects listened to sounds of individual musical instruments and matched these to instrument pictures. Second graders scored significantly higher than first graders; rank orders of instruments according to association difficulty, however, were markedly similar between grades. Results support the view that children bring much music knowledge to…

Examines the development of grapheme-phoneme conversion ability in normal and reading-age matched dyslexic readers. Thirty-six normal readers (mean age 9.5 years) and 18 children diagnosed dyslexic (mean age 12.1 years) served as subjects. (MP)

A study that compared the receptive and expressive prosodic abilities of 30 Dutch children (ages 4-6) with language impairments to the abilities of typical children, found they performed less accurately on a prosodic imitation task but did not differ on an emotion identification task. Children performed better with increasing age. (Author/CR)

Infants of five, seven, and nine months were shown two video images on monitors placed side by side. Images were accompanied by a soundtrack that matched one of the images. Results indicated that age-related changes in infants' coordination of auditory and visual depth information took place between the ages of five and nine months. (SH)

Event-related potentials (ERPs) to tone pairs and single tones were measured for 16 participants with specific language impairment (SLI) and 16 age-matched controls aged from 10 to 19 years. The tone pairs were separated by an inter-stimulus interval (ISI) of 20, 50 or 150 ms. The intraclass correlation (ICC) was computed for each participant…

The relationship between subtests of the Illinois Test of Psycholinguistic Abilities and the Developmental Test of Visual-Motor Integration to a comprehensive battery of reading measures was investigated in a sample of 77 poor readers in grades 2 through 6. (Author/PHR)

Examines short-term memory for spoken words ignored at the time of their presentation. Age differences in the persistence of memory was found. Suggests that relatively attention-free properties of short-term memory may change with development in childhood, and priority should be given to distinguish maturational and experiential influences on…

A study evaluated the ability of older adults to accurately perceive and retain Spanish in their short-term memory. Specifically, the study investigated differences in native language (English) auditory perception, short-term native language auditory memory capacity, monolingual age differences in auditory perception ability in an unknown…
