This study aims to identify similarities in morphological, phonological, lexical, and syntactical aspects between Arabic and English child language. It seeks to understand how children develop grammar at different stages, adhering to the rules acquired at each stage. This research analyzes YouTube videos featuring Arabic and English-speaking…

To obtain reliable information, it is important to identify and effectively question knowledgeable informants. Two experiments examined how age and the ease of distinguishing between reliable and unreliable sources influence children's ability to effectively question those sources to solve problems. A sample of 3- to 5-year-olds was introduced to…

Upon witnessing a causal event, do children's gestures encode causal knowledge that (a) does not appear in their linguistic descriptions or (b) conveys the same information as their sentential expressions? The former use of gesture is considered supplementary; the latter is considered reinforcing. Sixty-four English-speaking children aged 2.5-5…

A study of the late acquisition of the passive in Zulu used data from transcripts of naturalistic speech gathered in a longitudinal study of several children's speech development between 1.10 and 3.6 years of age. It was hypothesized that the productivity of the passive construction in Zulu is a factor facilitating acquisition. A range of…

Examined role of spontaneous gesture in 2- to 4-year-olds' counting and assessment of counting accuracy. Found that correspondence of children's speech and gesture varied systematically across age. Children adhered to one-to-one correspondence principle in gesture prior to speech. Counting accuracy related to correspondence of speech and gesture,…

Results suggest that children can use the rules of conversational sequencing to evaluate the need for an inference to the speaker's intent when speakers deliberately violate a rule. This ability is acquired by six or seven years of age, but children do not correctly infer the speaker's intent until they are eight or nine years old. (Author/RH)

Addresses questions about infant perceptual ability and the possibility of its decline as a function of development in the absence of specific experience. Compares English-speaking adults, Hindi-speaking adults, and 7-month-old infants on their ability to discriminate two pairs of natural Hindi (non-English) speech contrasts. (Author/RH)

Investigates expression of part-whole semantic relation by children 3 to 12 years old and indicates that older children prefer its use significantly more often. The part-whole semantic relation was also observed to take several linguistic forms, such as partitive, spatial, and possessive. Age, experimental task format, or type of experimental…

Two experiments examined toddlers' noun vocabularies and interpretations of names for solid and non-solid items. Results indicated that one side of the solidity-syntax-category organization mapping was favored. Seventeen- to 33-month olds do not systematically generalize names for solid things by shape similarity until they already know many…

Investigates young children's ability to adjust the content of their verbal responses according to what they know their listener knows. Younger and older three-year-old children were able to discern what another person knew and did not know and adjusted their responses accordingly. Younger three-year-olds tended to be underinformative. (SED)

Forty 3.5- to 4.5-year-olds discussed past events with their mothers and completed tasks indexing their ability to reason about conflicting mental representations and understanding of knowledge. Found that theory-of-mind scores were related to memory conversation participation, independent of age and linguistic skill, and to the frequency of…

Used head-mounted eye-tracking system to study kindergartners' and adults' moment-by-moment language processing ability as they responded to spoken instructions. Found that 5-year-olds did not take into account relevant discourse/pragmatic principles when resolving temporary syntactic ambiguities and showed little/no ability to revise initial…

Two studies examined children's first references to the mental states of perception, desire, and belief in themselves and others. In Study 1, children interacted with their mothers in a laboratory setting at 14, 20, and 32 months of age (n=52); in Study 2, children were observed in their homes at 3-month intervals from 18 to 42 months (n=32).…

Discourse and conversational analysis methods were used in a qualitative reconstruction of one aspect of the regularities in the way 61 children "do" personal reference. Of particular interest was the development of two reference forms: minimization--preference for simple (one word) forms, or recipient design--reference forms indicating…

Measures of vocabulary, phonological memory, nonverbal intelligence, and reading were taken from 80 children at ages 4, 5, 6, and 8 years. Comparisons revealed a significant shift in the causal underpinnings of the relationship between phonological memory and vocabulary development before and after age five. (Author/LB)
