Twenty-one apparently normal children (ages 18 to 34 months) with slow expressive language acquisition were evaluated initially and again at age 3. The late talkers also scored significantly lower in receptive communication and socialization. Followup showed nearly half the group remained delayed in expressive communication and socialization,…

Discusses methods of assessing language comprehension in apes. Considers the possible effect of brain physiology on the differences between productive and receptive language skills. Examines the possibility that differences between synaptic transmission and volume transmission, or transmission across extracellular spaces, of neurological impulses…

A 1-year followup of 10 children with delayed onset of early speech skills found that all 4 children who were still delayed had been delayed in language comprehension and gesture tasks the previous year whereas the 6 children who had "caught up" had demonstrated age-appropriate language comprehension and gesture usage earlier.

Children with Down syndrome often display speech-comprehensibility and grammatical deficits beyond what would be predicted based upon general mental age. Historically, speech-comprehensibility has often been treated using traditional articulation therapy and oral-motor training so there may be little or no coordination of grammatical and…

Three experiments examined the relation between language acquisition and other symbolic abilities in 18- and 26-month old infants. Infants' ability to learn either words or symbolic gestures as names for object categories were compared across age groups. Findings indicated that infants at both ages learned novel words as symbols for object…

Effects of receptive vs. expressive training of category labels on acquisition of generalized referential labels by six prelinguistic severely mentally retarded children (5-19 years old) were investigated. Data indicated that receptive training resulted in more accurate generalization to novel category members than did expressive training.…

Data on speech, language, performance IQ, school placement, and behavior are presented on 18 subjects diagnosed in childhood as "aphasic" and followed through adolescence. Results revealed slow but steady growth in language with expressive skills showing more rapid progress than comprehension. Performance IQ was highly correlated with language…

The construct validity of the Receptive-Expressive Emergent Language Scale (REEL) was investigated with 60 mentally retarded children (1-3 years old). Results indicated that REEL language ages were generally consistent with samples of communicative behavior and were also related significantly to indices of children's cognitive functioning.…

The study investigated the communicative effectiveness of word order in preschoolers' comprehension of meaning using simple questions and commands in an at-home play context. (ST)

The effectiveness of verbal, sign, and simultaneous systems for the acquisition of receptive language by an autistic boy was investigated. Results suggest nonsignificant differences among the three methods. (Author/SEW)

Comparison of 384 male and 91 female autistic children (three through eight years old) revealed that females as a group scored less well on intelligence tests. Boys also performed better than girls on eye-hand integration and perceptual tasks. Predictions of female superiority in affect and receptive vocabulary were not supported. (CL)

Examines the development of infants' ability to begin recognizing novel referents of common object names. In particular, the present experiment investigated the development of 12- to 20-month-old infants' ability to infer that an unfamiliar but categorically related object can be designated by a newly learned name for the object class. (Author/RH)

Compares the effectiveness of a visual only approach (mouthing and signing) with a simultaneous visual and auditory approach (signing and speaking) in teaching autistic-like children to communicate. Results suggest the simultaneous approach may be superior. In addition, receptive abilities precede expressive. Implications of therapeutic…

This study examined the relationship between fast mapping and word learning and between comprehension and production of new words with 30 young children with specific language impairment (SLI). Results suggest that children with SLI may need to hear a new word twice as many times as other children before comprehending and independently using the…

Five children with severe educational retardation, aged 5-12, were involved in sign training in which the spoken words corresponding to signs were receptively known to participants. Whether signs were taught concurrently or in a serial fashion, signs taught by total communication were acquired faster than those taught by sign-alone training.…
