Evidence that young children often claim ownership of their partner's contributions to an earlier collaborative activity, the "appropriation bias", has been attributed to shared intentionality ("Cognitive Development" (1998) 13, 91-108). The current investigation explored this notion by examining individual differences in the bias among 4- and…

This study aimed to evaluate the impact of individual differences in working memory capacity on number transcoding. A recently proposed model, ADAPT (a developmental asemantic procedural transcoding model), accounts for the development of number transcoding from verbal form to Arabic form by two mechanisms: the learning of new production rules…

Examines fourth grade children's memory for information contained in target sentences presented 24 hours earlier. Examines the occurrence of interference by presenting multiple choice response options consisting of a correct word, a new word, and a word which occurred in a previous sentence. Attempts to extend the principles of frequency theory.…

Explored effects of naturally-occurring peer interactions and repeated suggestive interviews on preschoolers' event memories. Found that suggestive interviews, combined with peer exposure, led to children's claims of witnessing target activities comparable to those of children who actually witnessed these activities. Assent rates for misleading…

Describes two experiments which investigated the use of distinctive feature codes in the storage of phonetic encoding information by 6- and 7-year-olds during short term memory tasks. A total of 106 children were presented with 30 lists of consonant-vowel syllables for recall. Data indicate that children encode the consonantal phones into sets of…

Analysis of the frequency and nature of error and post-error responses in serial choice reaction times of 84 children between 5 and 12 years essentially replicate findings in adults. (Author/MP)

This study compared 3- and 5-year-olds' reports of a true or false play interaction following repeated interviews. Findings indicated age-related improvements in performance. Three-year-olds questioned repeatedly about a false event made more errors in response to specific questions than their age-mates questioned about false details of a true…

Three studies involved kindergartners in a categorization task with an adult in collaborative and noncollaborative conditions; tested subjects on memory of who had performed which actions; and asked them to recategorize items independently. Results suggested that one process contributing to children's internalization of knowledge may involve…

Two experiments examined relation between age-related changes in retention and age-related changes in the misinformation effect. Found large age-related retention differences when participants were interviewed immediately and after 1 day, but after 6 weeks, differences were minimal. Exposure to misleading information increased commission errors.…

Investigated memory span and memory scanning in both auditory and visual modalities of 24 good and poor, 10-year-old readers. The major finding was that short-term memory function deteriorated over time in the poor reading group. (Author/LLK)

Groups of first-grade (mean age = 82 months), third-grade (mean age = 107 months), and fifth-grade (mean age = 131 months) children with a learning disability in mathematics (MD, n=58) and their normally achieving peers (n = 91) were administered tasks that assessed their knowledge of counting principles, working memory, and the strategies used to…
