Examined role of social-referential context in 13- and 18- month-olds' mapping of verbal and nonverbal symbols to object categories. Found that infants at both ages showed evidence of learning both words and sounds when the experimenter produced a label within a familiar naming routine, and failed to learn when labels were emitted from a baby…

Four experiments investigated children's ability to notice and remember events in which the acquisition of factual information occurs. Results indicated that children tend to report they have known newly learned information for a long time, suggesting that children have some understanding of knowledge acquisition, but not at the level of adults.…

Examined the nature of perceptual classification in children and young adults. Found that most children attend selectively to one stimulus dimension when making perceptual classification judgments. Suggests that this developmental trend does not appear to be a holistic-to-analytic shift but rather a trend toward greater consistency in following a…

Two experiments investigated perceptual primacy of dimensional and similarity relations in stimulus classification of mentally retarded children. Results support a distinction between separable and integral stimulus structures, but do not support an integral-to-separable shift in perceptual development. Results suggest implications for…

Three experiments investigated 4-, 6-, and 8-month-olds' perception of the audible, visible, and combined attributes of bimodally specified syllables. Results suggested that at 4 months, infants attended primarily to the featural information, at 6 months primarily to the asynchrony, and at 8 months to both features independently. (Author/KB)

Results revealed that (1) relevant verbal experience facilitated learning only for preschoolers, (2) irrelevant verbal experience did not interfere with learning, and (3) visual highlighting exerted no significant effects. (Author/MB)

Results of two experiments minimizing verbal encoding and response demands indicate that when the ceiling effects in no-mask target recognition are removed, the visual information processing rates for children and adults can be considered equivalent. (Author/RH)

Two experiments investigated kindergarten through fourth-graders' and adults' ability to evaluate the certainty of deductive inferences, inductive inferences, and guesses, and explain the origins of inferential knowledge. Findings indicated that children rated their own deductions as more certain than guesses, but when judging another person's…

Presents the results of three studies examining children's conception of the mind itself as an independent, active entity. Findings revealed a developing ability in children to interpret and produce statements personifying the mind and provided considerable evidence of children's movement toward a conception of the mind as an active agent…

A core task in language acquisition is mapping words onto objects, actions, and events. Two studies investigated how children learn to map novel labels onto novel objects. Study 1 investigated whether 10-month-olds use both perceptual and social cues to learn a word. Study 2, a control study, tested whether infants paired the label with a…

Describes three studies that examined how young children distinguish between the real, physical world and the mental world; between objects and thoughts; and between doing something and imagining it. (HOD)

Examined the use by children of the Novel Name-Nameless Category principle, under the framework that lexical principles are acquired in a developmental sequence. Results indicated that the particular principle was not available at the start of lexical acquisition but that exhaustive categorization ability and a vocabulary spurt occur…

Examined whether superior recall of items in event-based categorical relations, or "slot fillers," remained when association and typicality were controlled. Found that only children receiving the typical + high association slot-filler list showed significantly better recall than with the taxonomic-coordinate list, with no differences…

Examined 8- and 10-year olds' understanding of the unique features of and potential relations among mental activities. Found a developing tendency to organize mental activities on the degree to which memory was a component of the activity. Results suggest that a constructivist theory of mind develops in later childhood. (AA)

Visual and auditory processing of complex sentences was examined among 8- through 11-year-olds. Findings suggested a U-shaped learning pattern for on-line processing of restrictive relative clauses. Off-line accuracy scores showed different patterns for good and poor comprehenders. Incorrect local attachment strategy use was related to sentence…
