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…

Two social factors and their interactive effects were examined as possible influences on children's detection and reporting of inconsistent statements. Factors were the stated intention and the age of the speaker. (PCB)

This study compared the science vocabulary performance of 76 students with learning disabilities (LD) and 78 normally achieving (NA) students at elementary and intermediate grade levels. Findings indicated significant differences in receptive language performance between LD and NA students and differences in expressive language between older and…

Deaf children with signing parents, nonnative signing deaf children, children from a hearing impaired unit, oral deaf children, and hearing controls were tested on theory of Mind (ToM) tasks and a British sign language receptive language test. Language ability correlated positively and significantly with ToM ability. Age underpinned the…

This paper reviews the literature on grammatical knowledge in language comprehension in the preschool years from the perspective of sensitivity to structural contrasts. Studies of both direct and indirect evidence of sensitivity to structural contrasts were evaluated and showed that there may be a developmental sequence of increasing sensitivity…

A study examined developmental changes in talker recognition skills by assessing 72 children's (ages 3-5) recognition of 20 cartoon characters' voices. Four- and 5-year-old children recognized more of the voices than did 3-year-olds. All children were more accurate at recognizing more familiar characters than less familiar characters. (Contains…

Replication of a study that showed that deaf 15- to 18-year- olds could accurately identify a significant number of isolated signs presented well out in peripheral vision found that 8- to 12-year-olds could also identify such signs, although results showed a significant effect of age on performance.

A study compared the way in which subjects belonging to four different age groups produced written recall and summary responses after being presented with a narrative story. A seventh-grade-level, 500-word story that contained 78 idea units was presented to two groups of adolescents (mean ages, 14.14 years and 17.55 years) and two groups of adults…

A study of 45 hearing-impaired students (ages 10 to 19) investigated their understanding of English verb-particle combinations of varying syntactic and semantic difficulty. Results suggest an order of difficulty in learning. Idioms were found to be more difficult than literal meanings with little improvement over the age range of the subjects.…

Comparison of the Picture Vocabulary subtest of the Test of Language Development--Primary (TOLD-P-PV) and the Peabody Picture Vocabulary Test--Revised (PPVT-R) with first- through third-graders (N=48) revealed a strong correlation between the two receptive vocabulary measures. (CB)

Two experiments showed that: 5- and 6-year-old listeners have difficulties with spatial reference if it includes "left" and "right"; and 7-year-olds understand this limitation on the comprehension skill of younger children and make appropriate allowances by using more landmarks instead. (CB)
