Preterm birth (<37 gestational weeks) is associated with long-term risks for health and neurodevelopment, but recently, studies have also started exploring how preterm birth affects early language development in the 1st year of life. Because the timing and quality of auditory and visual input is very different for preterm versus full-term…

Over their 1st year of life, infants' "universal" perception of the sounds of language narrows to encompass only those contrasts made in their native language (J. F. Werker & R. C. Tees, 1984). This research tested 40 infants in an eyetracking paradigm and showed that this pattern also holds for infants exposed to seen language--American Sign…

FIFTEEN RESEARCH STUDIES IN CHILD DEVELOPMENT ARE SURVEYED. PARTICULAR EMPHASIS IS GIVEN TO FELDMAN WHO RECOMMENDS A "CODE-FIRST" PROGRAM FOR BEGINNING READING. THE TERM "CODE" REFERS TO THE LETTER SYMBOLS REPRESENTING THE CHARACTERISTIC SPEECH SOUNDS OF ENGLISH. SOME OF THE PROBLEMS IN PERCEPTION AND THE IMPLICATIONS FOR…

This study explored three aspects of the 2-month-old's perception of multisyllabic utterances. Questions addressed were: (1) Do infants perceive phonetic contrasts occurring either in the initial (Bada-Gada) or medial (Daba-Daga) positions of multisyllabic utterances; (2) Are infants more likely to perceive these contrasts in stressed as opposed…

Research findings concerned with the relationship between the child's oral language behavior and learning to read are described. A cognitive-biological approach to the child's perceptual system development is taken, and data are presented to support both the developmental point of view of language development and the point of view that the child…

Adults and 4-year-old children were tested to determine whether the children were able to decode sets of familiar minimal pairs as well as adults. They listened to words spoken in a normal voice and a whisper. Indications were that the 4-year-old's perceptual mastery of English phonology is not yet complete. (SW)

Perception and production data were collected from 28 children, ages 1 year 8 months to 3 years 11 months to test four specific hypotheses on the acquisition of initial fricatives and glides in English, based on the assumptions that perception precedes production and unmarked precedes marked. Perception data were collected by the Shvachkin-Garnica…

Phonological development in children is described in terms of four stages; (1) preverbal vocalization and perception (birth to 1;0); (2) phonology of the first 50 words (1;0 to 1;6); (3) phonology of simple morphemes (1;6 to 4;0); and (4) completion of the phonetic inventory (4;0 to 7;0). (CTM)

Three experiments examined the perception of a three-way voicing contrast by monolingual speakers of English. The results demonstrate that the perceptual mechanisms used by adults in categorizing stop consonants can be modified easily with simple laboratory techniques in a short period of time. (Author/PN)

Three ten-step series of synthetic speech stimuli were constructed: /raem/ to laem/, /raem/ to /waem/, and /laem/ to /yaem/. Within each series, differences consisted of variations in onset frequency and slope of transition in the second or third formant. These stimuli were presented to 5- to 7-year-old children in identification…

Stampe's (1969, 1973) hypotheses regarding innate mental phonological processes are tested against some of the extant data on speech perception. (AM)

A review of laboratory research estimating effects of mild hearing impairment on infant speech perception abilities, under conditions simulating mild hearing loss in normal hearing infants, suggests that even mild alterations of auditory input during infancy may have significant developmental consequences. Results support identification,…

A program for approximately 100 2- to 5-year-old culturally deprived Nashville, Tennessee, children was conducted in two community day-care centers. The children received instruction in groups of six or seven on a half-day basis for 5 days a week. Both language input and output were the focus of instruction, which was carried out through…

Smith (1973), Stampe (1972), and Braine (1973) believe that by the time the child speaks his perception is well-developed, and that any discrepancy between child forms and adult forms are due to organizational and production difficulties. Other linguists believe immature perception determines the form of child speech. This paper suggests that…

This study investigated the premise that disordered temporal order perception in retarded readers can be seen in the serial processing of both nonverbal auditory and visual information, and examined whether such information processing deficits relate to level of reading ability. The adult subjects included 20 in the dyslexic group, 12 in the…
