BACKGROUND Recent studies suggest that yoga practice may improve cognitive functioning. Although preliminary data indicate that yoga improves working memory (WM), high-resolution information about the type of WM subconstructs, namely maintenance and manipulation, is not available. Furthermore, the association between cognitive enhancement and improved mindfulness as a result of yoga practice re...

The purpose of this study is to determine the amount of correlation, if any, between the reverse audito-vocal digit memory span and the following: (1) General intelligence, (2) Vocabulary, (3) Interpretation of fables, (4) Chronological age. The Intelligence Quotient obtained by means of the Stanford Revision of the Binet-Simon Tests was used as a measure of general intelligence. The reverse au...

Objective: The aim of this study was to investigate whether people exposed to the Chinese Famine in fetal period or in multiple stages of childhood are associated with cognitive decline in adulthood. Furthermore, the nutritional environment of adulthood was explored as an important factor in this correlation. Methods: 1162 adults born between 1952 and 1964 were recruited. They were divided into...

Both attention-deficit/hyperactivity disorder (ADHD) and catechol-O-methyltransferase (COMT) genotype have been linked to altered dopaminergic transmission and possible impairment in frontal lobe functioning. This study offers an investigation of a possible interaction between ADHD diagnosis and COMT genotype on measures of working memory and executive function. Thirty-five adults with ADHD, wh...

We investigated sex differences in genetic and environmental effects on cognitive abilities among older adult twins. We drew participants from the Swedish Twin Registry; our sample included 647 twin pairs. Our cognitive measures included Synonyms, Block Design, Digit Span, Thurstone's Picture Memory, Symbol Digit, and general cognitive ability tests. Higher age was related to lower performance ...

This paper reports memory span data from 45 monolingual, normal-hearing children ranging in age from 3;5 to 5;11 years. A newly implemented methodology (here termed the “memory span game”) required participants to reproduce sequences of lights, or sequences of lights accompanied by sounds, by pressing appropriately matched buttons on a response box. Auditory stimuli used in the light-plus-sound...
