Recent work has reported that the insulin-like growth factor 2 (IGF2) promotes memory enhancement. Furthermore, impaired insulin or IGF1 functions have been suggested to play a role in the pathogenesis of neurodegeneration and cognitive impairments, hence implicating the insulin/IGF system as an important target for cognitive enhancement and/or…

Used path analysis in two experiments to examine possibility that age difference in infants' long-term retention were artifacts of correlated differences in learning rates or learning opportunities. Found that developmental declines in forgetting rates between 12 and 18 months were independent of developmental differences in learning. Age…

Reviews the literature on the relation between early memory development and corresponding changes in brain development of infants. Finds that an adult-like form of explicit memory emerges between 8 and 12 months of age, drawing heavily on limbic and cortical structures. Offers theoretical perspectives for studying the ontogeny of memory. (JW)

This study explored relationship between working memory (WM) and mathematical problem solving, comparing children with learning disabilities (LD) to chronologically age-matched and younger achievement-matched children on measures of WM, phonological processing, problem-solving, and word problem-solving accuracy. Found support for notion that…

Piaget's theory that distinct stages in the organization of memory correspond to successive stages in cognitive development was tested using 150 eighth graders. Cognitive levels were assessed with Inhelder and Piaget's balance beam task, initially, and again at seven months. Mnemonic levels were assessed with Piaget and Inhelder's memory of an…

Examined children's ability to accurately monitor sources of suggested information. Age differences were found in the degree to which a misleading suggestion led subjects to believe they actually remembered seeing events that had in fact only been suggested to them. Proposes that these age differences reflect developmental differences in the…

Three experiments with preschoolers tested the independence of the current state buffer from working memory. Findings indicated that when a teddy bear was an object put away with other toys, only half the preschoolers remembered its location despite explicit instructions. When the teddy was a character interacting with children, all remembered its…

Three experiments examined kindergartners' and second graders' retention in the context of two distinctiveness manipulations, the von Restorff and bizarre imagery paradigms. Results showed that: older children retained more information from lists of pictures or interactive images over 3 weeks than younger; younger children failed to benefit from…

Investigated effects of object reinstatement on event recall by 6- and 9-year olds'. Subjects were interviewed either 10 days and again 10 weeks after an event, or only 10 weeks after an event. Interviewing included free recall, prompts, and questions. Found that age, delay, and object reinstatement all affected amount and accuracy of recall. (JW)

Examined how elementary school students remember what they learn and how they learn in science and social studies. Found that students used long-term working memory for sorting, interpreting, and integrating representations of classroom experiences as they acquired knowledge and skills. Recollection 12 months later replaced details with inferences…
