From the very first moments of their lives, infants selectively attend to the visible orofacial movements of their social partners and apply their exquisite speech perception skills to the service of lexical learning. Here we explore how early bilingual experience modulates children's ability to use visible speech as they form new lexical…

Open-ended tasks are rarely used to investigate cognition in autism. No known studies have directly examined whether increased attention to the perceptual level of speech in autism might contribute to a reduced tendency to process language meaningfully. The present study investigated linguistic versus perceptual speech processing preferences.…

This article honours Adele Miccio's life work by reflecting on the utility of phonetic transcription. The first section reviews the literature on cases where children whose speech appears to neutralize a contrast in the adult language are found on closer examination to produce a contrast ("covert contrast"). This study presents evidence…

Research is reported which investigated the ability of four-month-old hearing infants to discriminate between gestures derived from American Sign Language. Findings show that infants possess the perceptual abilities to differentiate between signs that differ solely in terms of contrasts along a single underlying movement direction. (SED)

This paper reports on an experiment designed to collect data on children's perception and use of semantic attributes. Forty-five children ranging in age from 2 years 8 months to 6 years were given a picture test involving judgment of similarities between objects. The test consisted of 47 groups of pictures; each group contained a stimulus or a…

Discusses the possibility that early linguistic experience affects infant speech perception and that this effect may be of practical consequence in later language learning. (EKN)

The visual-auditory integrative ability of 12 language delayed children with nonspecific etiologies was compared with that of 12 normal children matched for age, sex, and IQ. A battery of tests measured auditory-visual integrative ability, visual motor ability, and perception of frequency distorted speech. Significant differences were found…

Various theories of learning for the categories "count noun" and "mass noun" are compared. It is argued that children assign words to these categories on the basis of intuitions arising from perception that are relevant to Macnamara's (1986) definitions of the categories. (39 references) (GLR)

The experiment described in this report investigates the effects of various cognitive cues in questions asked regarding the relationship of elements in pictorial depth perception. The subjects of this study are 40 third grade Black and Puerto Rican children. They are confronted with four pictures from the Hudson Depth Perception Tests and asked to…

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…

Work with verbal autistic children has demonstrated phonological, syntactic, and semantic production defects which are not understandable solely in terms of a developmental lag, but also suggest aspects of atypical linguistic development. This investigation is a preliminary attempt to test not only the production, but also the perception, of…

Several studies have begun to investigate the claim that children can make most phonological discriminations when they begin to speak. This paper investigates how well children aged 2;3 to 2;11 can discriminate between pairs of minimally different real words, and it shows that the results are affected by how well the children know the words. It is…
