It was hypothesized that subjective memory complaints represent the earliest sign of dementia in carriers of the presenilin-1 (PS1) mutation. A total of 122 subjects (44 males, 78 females) were included in this study. Forty of them were positive for the mutation in the PS1 gene (mutation positive, MP) whereas 82 showed negative results (mutation negative, MN). Subjects were active, functionally...

Data are presented on two computerized tests of everyday verbal learning: Paired associate learning of First-Last Names (FLN), and the Grocery List Selective Reminding Test (GLSRT). MANOVA and multiple regression analyses demonstrated that performance on FLN and GLSRT was most strongly related to age, with significant secondary associations found for gender, with females performing better than ...

Much attention has been paid to the enhancement of working memory, which can improve children’s lives. Part value memory training is that it activates prefrontal cortex. Therefore, important determine parts cortex are activated by training.

Fox (1994) purports to determine the appropriateness of the normative data for the Logical Memory subtest of the Wechsler Memory Scale-Revised for individuals in litigation and suggests that "...many of these people would have been incorrectly diagnosed as having a neuropsychological problem that did not exist." His data do not support such a conclusion, but rather appear simply to demonstrate ...

Previous research has shown that math anxiety can influence the math performance level; however, to date, it is unknown whether math anxiety influences performance on working memory tasks during neuropsychological evaluation. In the present study, 172 undergraduate students completed measures of math achievement (the Math Computation subtest from the Wide Range Achievement Test-IV), math anxiet...

OBJECTIVE Studies of adolescents with histories of maltreatment typically report specific cognitive deficits in higher order functioning and attention. Emerging evidence suggests that the cognitive difficulties seen in maltreated adolescents are much broader, and go beyond executive functioning impairments. This study examined whether maltreated adolescents exhibited cognitive deficits across a...
