Spontaneous gestures of a deaf child unexposed to sign language were studied to determine whether regularities existing within gestures were akin to morphological structure. The child's gestures, handshape/motion combinations forming a matrix for communication, suggest that structural regularity at the intraword level is a resilient property of…

Three experiments gauging 7- to 10-year-old children's ability to interpret and comprehend figurative language indicated that informative contexts could improve subjects' abilities to perceive idiomatic meanings. Subjects were less able to produce idioms than to comprehend them, but were able to perceive that language can be both figurative and…

The validity of mean length of utterance (MLU) and a measure of syntactic complexity were tested against the language assessment, remediation, and screening procedure on spontaneous speech samples from 87 children, concluding that MLU is a valid measure of clausal complexity up to 4:5 and that the measure of syntactic complexity is more valid at…

Investigated the effect of language on Chinese-speaking children's performance on false-belief tasks under three between-subjects conditions. Chinese-speaking adults and young children responded to false-belief tasks. Results revealed a rapid developmental pattern in the children's understanding of false beliefs and suggested the important role of…

Examined the processes by which children interpret homonyms. Participants were 2-and 3-year olds, 4-year olds, 7-year olds, and 10-year olds. Each child was asked individually to interpret keywords from stories read aloud by the examiner. Keywords were homonyms, nonsense words, or unambiguous words. (Author/VWL)

Considers the cross-linguistic findings concerning the early development of formal, arbitrary, grammatical systems in normal hearing and deaf children and in children with congenital brain abnormalities. Evidence is reviewed that shows an early acquisition of grammatical forms. (Author/JL)

Investigated the first verbs to participate in verb-object and subject-verb-object combinations and the temporal parameters of the spread of these combinations over different verbs, observing longitudinally young children acquiring English and Hebrew. Results indicated that the more verbs children already knew to combine in a certain pattern, the…

The current study attempts to differentiate effects of phonotactic probability (i.e. the likelihood of occurrence of a sound sequence), neighbourhood density (i.e. the number of phonologically similar words), word frequency, and word length on expressive vocabulary development by young children. Naturalistic conversational samples for three…

We hypothesize that the conceptual relation between a verb and its direct object can make a sentence easier ("the cat is eating some food") or harder ("the cat is eating a sock") to parse and understand. If children's limited performance systems contribute to the ungrammatical brevity of their speech, they should perform better on sentences that…

The present research investigated whether children's referential choices for verb arguments are motivated by pragmatic features of discourse referents across different developmental stages, not only for children learning null argument languages but also for those learning overt argument languages. In Study 1, the form (null, pronominal, or…

Analyses of longitudinal speech data collected from two children indicated that children rapidly acquire count/mass noun distinctions. (Author/CB)

Describes a study to determine: (1) the relationship between age and mean length of utterance measured in morphemes (MLU) in a group of normally developing two- and three-year-old chidren; (2) the standard error of MLU; (3) the relationship between MLU and age; and, (4) the ability of MLU to predict children's grammatical development. (SED)

Analyzes mothers' speech in free-play interactions with their 12- to 27-month-old children for frequency and type of fantasy relationships. Results indicate that the older the child, the more fantasy talk a mother is likely to use. (EKN)

Describes adjustments in speech patterns made by two- and three-year-olds when talking to their 14-month-old siblings and compares these changes with those made by mothers addressing their babies. Individual differences between the children indicate two types of influence on the adjustments made--pragmatic and emotional. (EKN)

Describes an experiment to see whether the words "front" and "back" introduce the concept of "front-back" or whether the concept preceded the words. Results show that (1) a complex disjunctive concept of "front-back" orientation precedes any knowledge of the words; (2) linguistically, "back" is comprehended before "front"; and (3) children at an…
