We explored the causal role of individual and age-related differences in working memory (WM) capacity in long-term memory (LTM) retrieval. Our sample of 160 participants included 120 children (6-13-years old) and 40 young adults (18-24 years). Participants performed a WM task with images of unique everyday items, presented at varying set sizes.…

The ability to navigate new environments has a significant impact on the daily life and independence of people with learning difficulties. The aims of this study were to investigate the development of route learning in Down syndrome (N = 50), Williams syndrome (N = 19), and typically developing children between 5 and 11 years old (N = 108); to…

Several judgment and decision-making tasks are assumed to involve memory functions, but significant knowledge gaps on the memory processes underlying these tasks remain. In a study on 568 adults between 25 and 80 years of age, hypotheses were tested on the specific relationships between individual differences in working memory, episodic memory,…

This study focuses on the development of face recognition in typically developing preschool- and school-aged children (aged 5 to 15 years old, "n" = 611, 336 girls). Social predictors include sex differences and own-sex bias. At younger ages, the development of face recognition was rapid and became more gradual as the age increased up…

A child who had had surgery at 5 months of age, and who had been treated at the time for post-traumatic symptoms (reported in a previous paper by the author), was interviewed 2 years later and almost 3 years later to test for possible verbal recall of his hospitalization. He appeared to have some memories of the experience at 29 months of age, and…

Interest in students who exhibit characteristics with difficulties in learning can be traced as far back as 1800. In order to better understand the complexities and causes of learning disabilities, many researchers (Bannatyne, 1968, 1974; Rugal, 1974) have investigated ways to better identify learners who struggle with academics. A strong argument…

The prion protein Met129Val polymorphism has recently been related to human long-term memory with carriers of either the 129[superscript MM] or the 129[superscript MV] genotype recalling 17% more words than 129[superscript VV] carriers at 24 h following learning. Here, we sampled genotype differences in retrieval-related brain activity at 30 min…

The nonword repetition (NWR) test has been shown to be a good predictor of children's vocabulary size. NWR performance has been explained using phonological working memory, which is seen as a critical component in the learning of new words. However, no detailed specification of the link between phonological working memory and long-term memory…

Explored whether developmental changes in the structure and coherence of preschoolers' personal narratives might provide some clues about childhood amnesia. Suggests that while children's narratives become more elaborate, more detailed, and more complex over the preschool years, children's recall of the same events over time is remarkably stable,…

Explored preschoolers' eyewitness testimony under conditions designed to maximize or degrade the quality of their event reports. Found that 3- to 4-year olds were highly accurate when questioned nonsuggestively about an engaging experience after a short delay, and could provide substantial information when prompted. However, they made many…

Fluctuations in cognitive task performance in older individuals have been reported. To examine intraindividual variability as a function of practice, 34 younger and 34 older female participants, aged 20-30 years and 70-82 years, respectively, performed a reading span task 16 times over four sessions. Each individual's recall accuracy was analyzed…

Reviews literature on development of children's and adults' long-term retention. Finds that forgetting is dominated by storage (not retrieval) failures; trace recovery is dominated by retrieval (not storage) operations; and storage failure rates decline with age in childhood, whereas only modest developments occur in retrieval recovery operations.…

Compared toys and real items as props for facilitating children's reporting of an event. Indicates that the effects of props depend on the nature of the items and the age of the children with whom they are used. Suggests that real items may provide one means of supporting recall, to enable children to provide their most complete and accurate…

Examined three-year olds' difficulty in recalling a false belief immediately after they discover the true state of affairs. Challenges the argument that children are genuinely amnesic and their false belief is deleted and no longer available for retrieval. Suggests that three-year-olds have been much underestimated in their capacity to undertake…

Examined the degree to which young children can use anatomically detailed dolls to show what they remembered of their experience in a case of suspected sexual abuse. Very young children had difficulty appreciating and exploiting a representational relation between themselves and a doll. Consequently, they provided more information verbally and…
