Verbal and nonverbal components of pointing initiation by Down's Syndrome children when looking at books were studied. Analysis of initiation patterns and point duration revealed possible developmental progression from a stage where point and exchange duration are linked to a stage where pointing becomes more detached from the exchange.

In a study of early functions of negation (rejection and denial), 48 children under age 3 were asked easy yes/no questions. The most likely age range for the appearance of error-free denial "no" at 1 year/8 months to 2 years/1 month supports the continuity theory of negation development. (Contains 27 references.)

Three experiments with children between 5 and 7 years are described. It is shown that nominal predication of an unknown word by a superordinate term enables young children to make appropriate inferences concerning its attributes. The results are discussed in relation to semantic development and reasoning in the young child. (Author/RM)

Children's understanding of the nature of polar terms and comparative terms between the polar opposites is discussed. (CHK)

Two transitional phases in the child's early language development are described; the first occurs between prelinguistic vocalization and one-word speech and the second between one-word and patterned speech. Cognitive, linguistic and affective inputs to the acquisition of reference and syntax are discussed in the light of the transitional…

Investigates the development of past tense expressions in the speech of children from 1.6 to 2.6. It is shown that this development depends crucially on the child's cognitive construction of the time dimension, as described by Piaget. (Author/RM)

Interpersonal functions of everyday caretaker speech usage are examined when addressed to toddlers, threes and fours. Results support hypotheses derived from Piagetian theory concerning early developments in ego-differentiation. (Author/RM)

Children in grades 1-3 were asked to retell and explain a series of riddles. Ability to recall riddles was not predictive of ability to explain them. Three cognitive factors seemed to determine level of riddle competence. Implications concern the relationship of riddle competence to reading ability and metalinguistic facility. (CHK)

A longitudinal study of three children examined the relation between object permanence and language development. (Author/NCR)
