If good proficiency in L2 entails the acquisition not only of many single words but of many lexical chunks as well, it must then be asked how all this additional lexis is to be committed to long-term memory in the limited time available on non-intensive classroom-based language courses. If it is the case that a significant fraction of…

The purpose of this review is to provide educational practitioners with a brief overview of cognitive load theory (CLT) and its major implications for learning. To achieve this objective, the article includes a short description of human cognitive architecture as conceived by cognitive load theorists. Following this overview, the article provides…

Extensive research has shown that the hippocampus is necessary for consolidation of long-term spatial memory in rodents. We reported previously that rats using a place strategy to solve a cross maze task showed sustained phosphorylation of hippocampus cyclic AMP response element-binding protein (CREB), a transcription factor implicated in…

This study examined the extent to which children's cognitive abilities in kindergarten and their mothers' education predict their single-digit and procedural calculation skills and the covariance of these with reading skill in Grade 4. In kindergarten, we assessed children's (N=178) basic number skills, linguistic skills, and visual attention. In…

A broad range of priming data has been used to explore the structure of semantic memory and to test between models of word representation. In this paper, we examine the computational mechanisms required to learn distributed semantic representations for words directly from unsupervised experience with language. To best account for the variety of…

Long-term memory formation is regulated by many distinct molecular mechanisms that control gene expression. An emerging model for effecting a stable, coordinated pattern of gene transcription involves epigenetic tagging through modifications of histones or DNA. In this study, we investigated the regulation of histone phosphorylation in the…

Several data have shown that the neural cell adhesion molecule (NCAM) is necessary for long-term memory formation and might play a role in the structural reorganization of synapses. The NCAM, encoded by a single gene, is represented by several isoforms that differ with regard to their content of alpha-2,8-linked sialic acid residues (PSA) on their…

Consolidation refers to item stabilization in long-term memory. Retrieval renders a consolidated memory sensitive, and a "reconsolidation" process has been hypothesized to keep the original memory persistent. Some authors could not detect this phenomenon. Here we show that retrieved contextual fear memory is vulnerable to amnesic treatments and…

Transcriptional activation is a key process required for long-term memory formation. Recently, the transcriptional coactivator CREB-binding protein (CBP) was shown to be critical for hippocampus-dependent long-term memory and hippocampal synaptic plasticity. As a coactivator with intrinsic histone acetyltransferase activity, CBP interacts with…

This study examined the effects of misleading information on children's memory for a real-life event. In play sessions involving an experimenter, 36 6-year-olds and 36 9-year-olds individually participated by playing games with a research assistant. In the sessions, six critical items were present: two items identified the room; two identified the…

A laboratory procedure was developed for assessing imitation in the second year of life. Results demonstrate that 14- and 24-month-olds can imitate a simple action with an unfamiliar object, both immediately and after a 24-hour delay. Implications for research design and theory of infant memory are discussed. (RH)

Seven- and ten-year-olds listened to taped stories. In one version, familiar television characters were described as having attributes incongruous with those the children knew from television. Three weeks later, children's recall of the stories indicated considerable shifts in memory toward their preexperimental knowledge of the TV characters.…

This study of 429 nonclinical adults found that similar proportions of those reporting histories of sexual, emotional, and physical abuse reported that they had periods without memory of their abuse. The enormous variance in reported quality of childhood memories and the common recovery of forgotten childhood memories were both found to be…

Long-term recall memory was assessed in 14- and 16 month-olds using a nonverbal method requiring subjects to reenact a past event from memory. The results demonstrated significant deferred imitation after delays of two and four months, and that the toddlers retained and imitated multiple acts. (MDM)

A theoretical framework of working memory is proposed in which cognitive processes are viewed as a sequence of stable states representing end products of processing. In skilled activities, acquired memory skills allow these end products to be stored in long-term memory and kept accessible through short-term memory retrieval cues. (SLD)
