The influence of motor knowledge on speech perception is well established, but the functional role of the motor system is still poorly understood. The present study explores the hypothesis that speech production abilities may help infants discover phonetic categories in the speech stream, in spite of coarticulation effects. To this aim, we…

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)

A preliminary experiment was conducted to explore the effects of illiteracy on hemispheric specialization. Groups of literate and illiterate Iranian children were tested on three dichotic tapes consisting of monosyllabic animal names, double-digit numbers, and nonverbal environmental sounds. All children were also tested for handedness and for…

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)

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…

Some very practical questions about how children learn the first language compel us to study brain functions and how these functions evolve. They also bring the studies of linguistics and neurology together. The purpose of this paper is to relate some of the research that describes language acquisition with the research about the early development…
