We tested 6- to 7-year-olds, 18- to 22-year-olds, and 67- to 74-year-olds on an associative memory task that consisted of knowledge-congruent and knowledge-incongruent object-scene pairs that were highly familiar to all age groups. We compared the 3 age groups on their memory congruency effect (i.e., better memory for knowledge-congruent…

Does category representation change in the course of development? And if so, how and why? The current study attempted to answer these questions by examining category learning and category representation. In Experiment 1, 4-year-olds, 6-year-olds, and adults were trained with either a classification task or an inference task and their…

Cognitive performance is characterized by at least two distinct life course trajectories. Many cognitive abilities (e.g., "effortful processing" abilities, including fluid reasoning and processing speed) improve throughout early adolescence and start declining in early adulthood, whereas other abilities (e.g., "crystallized"…

Based on a 2-component framework of episodic memory development across the lifespan (Shing & Lindenberger, 2011), we examined the contribution of memory-related binding and monitoring processes to false memory susceptibility in childhood and old age. We administered a repeated continuous recognition task to children (N = 20, 10-12 years),…

Under what conditions will people generalize and remember observed social information? Preschool- (n = 44) and young school-age (n = 46) children and adults (n = 40) heard short vignettes describing characters' actions and motives on a single occasion. Characters were introduced using either proper names or category labels. Test questions asked…

The present study investigated developmental differences in the effects of repeated interviews and interviewer bias on children's memory and suggestibility. Three- and 5-year-olds were singly or repeatedly interviewed about a play event by a highly biased or control interviewer. Children interviewed once by the biased interviewer after a long…

Examined developmental change in category representation in the first year of life. Experiment 1 tested infants of three, five, and seven months in a visual recognition memory procedure. Results indicated change in the nature but not the structure of infant form categories. Experiment 2 ruled out a priori preferences as the basis for findings of…

Compared verbal and visuo-spatial working memory (WM) performance under initial, gain, and maintenance conditions for nine age groups from 6 to 57 years to determine if differences were attributable to specific or general processing functions. Found support for a general-capacity explanation of age-related differences, reflecting demands placed on…

A longitudinal study examined memory span at 5, 7, and 12 months in full-term and low-birth-weight preterm infants. Findings were similar for both groups: longer spans were more difficult, especially at younger ages, memory capacity increased over first year of life, there was marked recency effect for spans of 3 and 4 at all ages, and modest…

Examined European-American 19-year-olds' self-defining memories about relationships with parents and/or peers. Found that parent memories emphasized separation more so than peer memories, which emphasized closeness. Parental separation was exemplified by parental divorce experiences, parent closeness by comforting a grieving parent, and peer…

Forty 3.5- to 4.5-year-olds discussed past events with their mothers and completed tasks indexing their ability to reason about conflicting mental representations and understanding of knowledge. Found that theory-of-mind scores were related to memory conversation participation, independent of age and linguistic skill, and to the frequency of…

Examined visual attention and implications for recognition memory in a longitudinal sample of full-term and preterm infants at 5, 7, and 12 months. Found differences between full-terms and preterms in several aspects of visual attention. Infants showed consistent attentional styles over various conditions. Shorter looks and higher shift rates…

Three experiments found that after enacting everyday actions using toys or toy substitutes (a block or stick), preschoolers were more likely than kindergartners or second graders to claim they had played with a toy when a substitute had been used. However, preschoolers rarely claimed they had played with a substitute when a real toy was involved.…

Nonword spellings were obtained from children in kindergarten through third grade in a study of the development of young children's phonological and orthographic knowledge. Results indicated that young children's nonword spellings reflected the joint influences of linguistic knowledge and psychological processes. (GLR)

Used cross-sectional life span data from normative sample for Woodcock-Johnson Psycho-Educational Battery to examine independence of age-related cognitive changes in childhood and adulthood. Found that majority of age-related differences were shared across different cognitive variables and were well predicted by individual differences in…
