Between 6 and 9 years of age, children's free associations shift from syntagmatic to paradigmatic relationships. "Syntagmatic relations" are words that are syntactically adjacent, thematically related ("summer-vacation"), or both; "paradigmatic relations" are words from the same grammatical class, taxonomic category…

A developmental reversal in false memory is the counterintuitive phenomenon of higher levels of false memory in older children, adolescents, and adults than in younger children. The ability of verbatim memory to suppress this age trend in false memory was evaluated using the Deese-Roediger-McDermott (DRM) paradigm. Seven and 11-year-old children…

Four word-learning studies exposed 2-year olds to novel verbs and nouns. Found that knowledge of what action or object was impending was not necessary for learning the words; children learned a novel verb for an intentional but not an accidental action; and children learned a novel noun for an object being sought, but not ones rejected while…

Three experiments assessed the claim that preschoolers override form class cues in the interest of honoring word- meaning assumptions when acquiring new labels. Results demonstrated that children respected the form class cues when these cues and word-meaning assumptions suggested conflicting interpretations. It was suggested that past findings…

Examined how college-age adults and 8-, 11-, and 13-year-olds retrieve semantic information from long-term memory. Closely comparable results were obtained across ages. This developmental similarity is discussed in relation to developmental differences in the use of semantic information in other cognitive tasks. (JMB)

Two studies examined whether preschoolers use whole-part juxtaposition to accurately interpret novel part terms. Results confirmed that children do use juxtaposition to guide learning of novel part terms and that such use was not due to memory effects nor to recognition of the grammatical frame accompanying juxtaposition. Children readily used…

Four studies examined the influence of essentialist information such as internal properties and perceptual similarity on 3-, 4-, and 5-year olds' interpretations of labels. Results suggested that children have essentialist beliefs about animals, but not about artifacts, and that these beliefs interact with children's assumptions about word meaning…

Dissimilarity judgments of all possible pairs of 10 animal names were obtained from first-, third-, and sixth-grade children, and college students. Analysis with multidimensional scaling procedures revealed a semantic space consisting of the features of size, domesticity, and predativity. (Author/JMB)

Developmental differences in the relative salience of features in concept representations in semantic memory and their contributions to differences in cued recall were examined in two experiments. Subjects were second graders, fifth graders, and college students. Results showed that recall varied with feature salience, with salience greatest for…

Three experiments explored the development of formal logical reasoning between Grades 4 and 12 and the role of semantic content in the solution of Wason's (1966) selection task problems. Results suggest that formal logical reasoning is not generally present during the fourth or sixth grades and that formal logical competence becomes available in…

Compared teaching and learning measures of 16 mother-child and sibling dyads playing a picture categorization game. Found that although siblings' teaching styles directed target children to make the correct choices, mothers provided information to help them make choices on their own, suggesting differences in how mothers and siblings interpreted…

Sampled the speech of American, French, and Swedish mothers to their one-year olds, to analyze distribution of phonetic parameters of adult speech, as well as children's own early words. Found that variability is greater in child words than in adult speech, and mother-child dyads showed no evidence of specific maternal influence on phonetics of…
