Background: In the last few years, experimental data have been reported on differences in implicit memory processes of genetically distinct groups of individuals with Intellectual Disability (ID). These evidences are relevant for the more general debate on supposed asynchrony of cognitive maturation in children with abnormal brain development.…

The nature of predictive relations between early language and later cognitive function is a fundamental question in research on human cognition. In a longitudinal study assessing speed of language processing in infancy, Fernald, Perfors and Marchman (2006 ) found that reaction time at 25 months was strongly related to lexical and grammatical…

Schools are a central interface between evolution and culture. They are the contexts in which children learn the evolutionarily novel abilities and knowledge needed to function as adults in modern societies. Evolutionary educational psychology is the study of how an evolved bias in children's learning and motivational systems influences their…

This study examined 4- and 6-year-old children's understanding of the causal relation between the use of a rehearsal strategy and increased recall. In Session 1, children were given two study-recall trials and, on the second trial, were asked to describe their study behavior. In Session 2, children viewed videotaped models and made judgments…

In two experiments, the ability of children younger than 20 months to engage in delayed ordered recall was investigated. In the first experiment, 13- and 16-month-old children were presented with 2-step event sequences and tested for recall, first, immediately following the event and second, after a one-week delay. Sequences were novel-causal,…

Examined in three studies were the influence of perceptual organization on children's memory and the relationship between operational thought and memory performance. In the first study, 72 children at 5, 7, and 9 years of age were given a series of Piagetian tasks and a memory task. Subjects were presented with 10 color-shape pairs depicted in…

Progress is now being made toward ascertaining the specific effects of rearing conditions on brain and behavior, the properties of the environment that contribute to these effects, and the developmental periods in which brain tissue is most sensitive to environmental modification. (Author/RH)

Preschool children were tested for their understanding of the use of definite and indefinite articles in 2 kinds of story-telling tasks. (ST)

The development of the ability to use taxonomic, phonemic and sense impression categories as dimensions of encoding was investigated using third and fifth graders and college students. (ED)

Examined the presence or absence of class inclusion and hierarchical classification skills in relation to organizational memory strategies in kindergarten and first grade children. (ED)

Reports results of an exploratory study in which a total of 80 children (in kindergarten, first, third and fifth grades) were interviewed in order to sample their knowledge of how certain classes of variables act and interact with one another to affect the quality of an individual's performance on a retrieval problem. (ED)

This study is based on an earlier investigation by Brant and Trabasso, in which it was demonstrated that 4-year-old children could perform transitive inferences when training forced information encoding by involving questions about two comparative dimensions of an object (long and short). The present study was designed to examine the sources of…

Investigated the influence of schooling and environment on young children's memory and cognitive skills. Subjects were five- and six-year-old Mestizo and Quechua Indian children living in jungle villages or city slums in Peru. Samples of upper-middle-class children in Lima and poor children in Detroit were also tested. (JMB)

Five experiments investigated whether the cued recall of children and adults differed for classified events featuring different category and relation types. Recall for events differed strongly for children and adults. Differences were attributed to properties of the internal structure of event representation in memory. (SKC)
