Impairment of hippocampal function precedes frontal and parietal cortex impairment in human Alzheimer's disease(AD). Neurotrophins are critical for behavioral performance and neuronal survival in AD. We used complex and radial mazes to assess spatial orientation and learning in wild-type and B6-Tg(ThylAPP)23Sdz (APP23) animals, a transgenic mouse…

Improvements in 5- and 7-year-olds' acquisition and retention of related concept pairings were examined when additional similarities and differences between pair members were provided. Using a standard paired-associate learning paradigm, children learned 18 related picture pairs; some of the children either were given or produced additional…

The purpose of this investigation was to quantitatively and qualitatively identify the study methods and learning strategies that veterinary students used to study anatomy during their first year of professional school and to correlate these with their academic achievement and long-term recall of information. It was surmised that active study…

This study investigates the validity of the Stanford Binet Intelligence Scale-Fourth Edition (S-B:4) for use with students with learning disabilities. It compares the performance of 18 elementary-age students on the S-B:4 and the Kaufman Assessment Battery for Children (K-ABC). The subjects were identified by their school as having learning…

Measures of memory for order were correlated with measures requiring mental manipulation, achievement, and aptitude using college and fifth grade students. A significant relationship was found for fifth graders but not for college students, suggesting that the nature and capacity of short-term memory changes with age. (Author/PN)

This study examined cognitive ability, short-term verbal memory, and speech perception in relation to phonological awareness in 42 gifted and 49 regular 3rd and 4th graders and in 61 prereading kindergartners. Those with higher cognitive reasoning skills scored higher on tasks of phonological awareness than those with lower reasoning skills.…

A correlational study examined the relationship between test performance and four study processes (encoding, word meaning, organizing, and executive control). Results with 123 college freshmen trained to use study strategies suggest that executive control is related to test performance and that trained subjects select a variety of strategies…

The hypothesis that coping with novelty is a key aspect of intelligence is not supported by the data of Sternberg and Gastel. It is contended that these authors committed a common error by interpreting correlations involving difference scores without reference to the properties of the components of the difference. (SLD)

This paper suggests that some neuroscience concepts particularly concerned with brain pathways in trauma and fear, as well as the neurobiology of emotion, provide an additional vertex to the psychoanalytic understanding of patients' material. The role of the body has been neglected in psychoanalytic thought and formulations in favour of purely…

Two studies investigated the relationship between working memory capacity (WMC), adult age, and the resolution of conflict between familiarity and recollection in short-term recognition tasks. Experiment 1 showed a specific deficit of young adults with low WMC in rejecting intrusion probes (i.e., highly familiar probes) in a modified Sternberg…

The present study was aimed at simultaneously determining on the same subject, the effects of stress on retrieval of flexible (contextual or temporal) or stable (spatial) information. Three behavioral paradigms carried out in a four-hole board were designed as follows: (1) Simple Discrimination (SD), in which mice learned a single discrimination;…

This study examined the correlates of symptom-seeking behavior for Alzheimer's disease (AD) among middle-aged persons. Symptom seeking, the tendency to search for signs of disease, is one manifestation of an individual's concern about developing AD. The data were obtained from a survey of two subsamples of 40-60 year old adults: 1) 108 adult…

In three experiments, fifth graders and college students watched a videotaped peer model executing two differentially effective associative-learning strategies. Observation of the model did not result in the consistent use of that strategy by fifth graders. College students did appear to benefit from the observational-learning opportunity.…

An experiment was designed to compare the speed with which normal and disabled readers in two age groups retrieved semantic information from memory. Results indicate that disabled readers need more time to retrieve categorical information from memory than normal readers. (Author/LMO)
