The correlation between a measure of working memory capacity (WMC) (Operation Span) and a measure of fluid abilities (Raven Advanced Progressive Matrices) was examined. Specifically, performance on Raven problems was decomposed by difficulty, memory load, and rule type. The results suggest that the relation between Operation Span and Raven is fairly constant across levels of difficulty, memory ...

The purpose of this study was to analyze the cardiovascular effects induced by mental stress evoked by different stressors in patients with recent uncomplicated myocardial infarction. Twenty four males, aged 52 +/- 10 years, were studied 45 +/- 22 days after uncomplicated myocardial infarction in the absence of specific cardiovascular drugs. During electrocardiographic and hemodynamic monitorin...

despite the fact that the contents of items on the raven's progressive matrices have little similarity to the content of subjects taught in school, the correlation coefficients between iq scores and achievement test scores have been estimated to be about 0.5. six groups of 20 students were randomly selected from the first, second, and third grades of urban and rural guidance schools in sha...

We compared the relationships among action-control beliefs, intellective skill, and actual school performance in samples of children from Tokyo (n 1⁄4 817, grades 2–6), Los Angeles (n 1⁄4 657), and West Berlin (n 1⁄4 517). Although these samples have been utilised in other comparative studies we have conducted, the role and function of intellective skill, as measured by the Raven Progressive Ma...

Recent studies (e.g. Dawson et al., 2007) have reported that autistic people perform in the normal range on the Raven Progressive Matrices test, a formal reasoning test that requires integration of relations as well as the ability to infer rules and form high-level abstractions. Here we compared autistic and typically developing children, matched on age, IQ, and verbal and non-verbal working me...

INTRODUCTION Lower urinary tract dysfunction (LUTD) are voiding dysfunctions without anatomical or neurological defects. The diagnosis is primarily clinical, with symptoms standardized by the International Children's Continence Society. Few studies relate quality of life of patients with cognitive and school performance. OBJECTIVE To evaluate milestones of bladder control, daily problems, qua...
