Two experiments test hypothesis that development of children's comprehension monitoring skills in the referential communication paradigm is based in part on ability to differentiate the literal sentence meaning of speaker's direction from the meaning or intention that speaker wished to convey.

Explores the relations among combinatorial capacities in language, symbolic play, blockbuilding, and nonsemantic action sequences within a sample of 18- to 24-month-old children, as well as assessing the developmental level of a selected subset of concepts. (HOD)

Examined in a longitudinal study of children were correspondences and correlations between early language development on the one hand, and the manipulation of objects and play development on the other. There were developmental correspondences between the onset of five language landmarks (the emergence of first word, referential word, demonstrative…

An experiment examined whether children of different developmental stages expressed different levels of fear while viewing episodes of the television program, "The Incredible Hulk." Preoperational (3 to 5 years old) and concrete operational (9 to 11 years old) children were shown short videotaped segments taken from the program. Using…

This research is testing the suggestion that acquisition and representation of formal language knowledge of dysphasic children is qualitatively different from the normal language acquisition/representation processes. In a cohort-sequential design, aspects of language and cognitive development of 120 dysphasic children aged 6-14 are being analyzed…

Explores the underlying knowledge that children have about the relationship between the structure of requests and the relative status of speakers and listeners. Shows that the three age groups (preschoolers, 5-year-olds, and 10-year-olds) could systematically differentiate the requests by means of syntactic directness or semantics. (HOD)
