Two experiments investigated the role of spatial prototypes in estimates of location. Found that adults and children ages 7 to 11 years overestimated distances between target locations in different regions and that none displaced objects toward the region centers. Even with boundaries removed during testing, adults and children overestimated…

Describes how veteran elementary teacher at international school in Saudi Arabia uses her knowledge of brain research to design instruction that will enhance student retention of new geographic concepts. (Contains 11 references.) (PKP)

Working memory, the ability to temporarily retain task-relevant information across a delay, is frequently investigated using delayed matching-to-sample (DMTS) or delayed Go/No-Go tasks (DGNG). In DMTS tasks, sample cues instruct the animal which type of response has to be executed at the end of a delay. Typically, performance decreases with…

Imitation is an important means by which infants learn new behaviours. When infants do not have the opportunity to immediately reproduce observed actions, they may form a memory representation of the event which can guide their behaviour when a similar situation is encountered again. Imitation procedures can, therefore, provide insight into infant…

The retrieval of temporal-order versus spatial-location information was investigated using fMRI. The primary finding in the hippocampus proper, seen in region of interest analyses, was an increase in BOLD signal intensity for temporal retrieval, and a decrease in signal intensity for spatial retrieval, relative to baseline. The negative BOLD…

We tested the impact of associative strength and retrieval heuristics in false source memory. We arranged 12-item associative lists in descending order of backward associative strength to a critical non-presented item and then split them into 6-item sub-lists at the median. High- and low-strength sub-lists were correlated with presentation source.…

This article describes school desegregation as a 3-generational, intricately linked process. The 1st generation included efforts toward physical desegregation for African American students; the 2nd generation emphasized equal access to classrooms, teaching bias, and ability groups; and the challenges of the 3rd generation include barriers to equal…

Twenty preschoolers with specific language impairment (SLI) and 20 age matches with normal language (NL) participated in a study to determine whether phonological memory or semantic knowledge predicted word-learning success. Poor learners' performance was analyzed to investigate whether phonology or semantics contributed more to word-learning…

Purpose: The purpose of this study was to compare adults with and without dementia on capacities to consent to treatment as assessed by three instruments. Design and Methods: Eighty-eight older adults with mild to moderate dementia were compared with 88 matched controls on four indices of legal competency to consent to medical treatment as…

The mnemonic device can be a terrific tool to help students memorize those things that are so easy to forget. A mnemonic device is a trick or strategy to help remember something. Adults use them every day. Frequiently, they may use a rhyme to help them remember how many days are in each month and they often use associations or alliterations to…

The paper describes the performance of three children with specific visuospatial working memory (VSWM) impairments (Study 1) and three children with visuospatial (nonverbal) learning disabilities (Study 2) assessed with a battery of working memory (WM) tests and with a number of school achievement tasks. Overall, performance on WM tests provides…

Nonhuman animals, like humans, appear sensitive to the structure of the elements of sequences, perhaps even when the structure relates nonadjacent elements. In the present study, we examined the contribution of chunking, rule learning, and item memory when rats learned serial patterns composed of two interleaved subpatterns. In one group, the…

Evidence from neurologically normal subjects suggests that repetition priming (RP) is independent of semantic processing. Therefore, we may expect patients with a selective deficit to conceptual knowledge to exhibit RP for words regardless of the integrity of their semantic representations. We tested six patients with semantic dementia (SD) on a…

Memory for familiar people is essential to understand their identity and guide social interaction. Nevertheless, we know surprisingly little about the structure of such memory. Previous research has assumed that semantic memory for people has a categorical structure, but recently it was proposed that memory for people consists only of associations…

When normal participants are presented with written verbal short-term memory tasks (e.g., remembering a set of letters for immediate spoken recall) there is evidence to suggest that the information is re-coded into phonological form. This paper presents a single case study of MJK whose reading follows the pattern of phonological dyslexia. In…
