Experiments are described in which students listened to messages describing the placements of numbers in imaginable matrices. Recall was tested by having students write in the correct cells of a blank matrix. Results appear consistent with a modified level of processing approach. (Author/RM)

Investigates the developmental differences in spatial exploration and memory, depending on the purposes for which children six- to seven- and eight- to nine-years-old explored the space. The results suggest that children's knowledge of large-scale space is tailored to the purpose of acquiring such information. (Author/BB)

This study presents a systematic investigation of three factors which seem necessary to initial success in obtaining recall facilitation when list member cues are presented during free recall. (Author/KM)

Performance of mildly mentally retarded and nonretarded persons was compared in two experiments designed to identify processes of auditory sensory memory. A theoretical model was proposed to incorporate the current pattern of results. (Author)

Two experiments investigated extent to which English- and German-speaking childrens' mental arithmetic was constrained by working memory. Found higher mental addition spans when numbers were visible throughout calculation than when not. Variation in addition span with age and arithmetical operation difficulty approximated to a linear function of…

This study used event-related potentials (ERP) and visual preference technique to assess 6-month olds' ability to recognize their mothers' face. Results of five experiments suggested that infants can recognize their mothers' face, but the neural processes accompanying recognition depend on the difficulty with which mothers can be discriminated…

Investigated the specificity of reading-disabled children's deficits in working memory capacity. Found that reading-disabled 10-year-olds performed worse than normal-reading children, matched for chronological age and reading age, on all measures of working memory capacity. Their poorer performance seemed to be due to a general lack of capacity…

Tobacco use is a major health problem that is estimated to cause 4 million deaths a year worldwide. Nicotine is the main addictive component of tobacco. It acts as an agonist to activate and desensitize nicotinic acetylcholine receptors (nAChRs). A component of nicotine's addictive power is attributable to actions on the mesolimbic dopaminergic…

Post-retrieval interference with a memory has uncovered a phenomenon known to the field as reconsolidation. In this article, we will review the specific molecular mechanisms that have been implicated in reconsolidation. As a result of numerous studies over the past five years, it can now be said with a fair amount of certainty that reconsolidation…

The regulation and function of the calcium-dependent phosphatase calcineurin (CaN, protein phosphatase 2B) in learning and memory remain unclear, although recent work indicates that CaN may play a differential role in training and reversal training. To gain more insight into the involvement of CaN in these two types of learning, hippocampal CaN…

It is known from studies outside the brain that upon binding to its receptor, angiotensin-(1-7) elicits the release of prostanoids and nitric oxide (NO). Cyclooxygenase (COX) is a key enzyme that converts arachidonic acid to prostaglandins. Since there are no data available so far on the role of COX-2 in the amygdala, in a first step we…

The issue of whether information to which little or no attention is paid can have lasting effects is of interest to psychologists as well as educators and advertisers. Two experiments were designed to examine whether focused attention is required, whether the immediate memory task is important, or whether subjects' knowledge that repetitions are…

In two experiments, learning disabled (LD) students were taught attributes of North American minerals via mnemonic instruction, free study, or a visual-spatial display condition similar to that proposed by Engelmann and Carnine (1982). In the first experiement, 36 junior high school-age LD students were taught specific attribute values (hardness =…

The short-term recall of word-triads was tested, comparing retention over three types of intervals within 24 preschoolers. Results suggest that the condition effect in short-term recall did not disrupt the long-term storage of the items. (Author/CS)
