In 15 normotensive subjects, 17 newly diagnosed, untreated hypertensive patients, and 22 effectively treated hypertensive patients, a battery of neuropsychological tests was given. All subjects were neurologically asymptomatic. The neuropsychological battery included tests evaluating global cognitive functions (Card Sorting Test, Wechsler Memory Scale, Progressive Matrices 1938), as well as spe...

The search for valid and reliable methods of detecting malingering and distortion has become an increasingly important task for forensic psychologists and neuropsychologists. This report highlights several important methodological issues commonly observed in research on the prediction of malingering. The choice of indices for determining optimal cutoff scores on the utility of existing measures...

A meta-analysis of 27 primary studies was conducted to examine the relationship between neuropsychological functioning and driving ability for adults with dementia. When studies using a control group were included, the relationship between cognitive measures and on-road or non-road driving measures was significant for all reported domains; mean correlations ranged from.35 to.65. Caregiver repor...

In this study, we describe an fMRI version of the verbal fluency test. This is the second in a series of fMRI adaptations of classical neuropsychological tests, for which normative samples of functional activation have been collected from unimpaired control subjects and structured in a manner that makes individual patient evaluation possible in terms of familiar z-score distributions. This fMRI...

Previous research has shown that fine motor control (MC) performance, measured with a computerized task, was less accurate in children with ADHD and in their unaffected siblings, compared to healthy children. This might indicate a shared genetic etiology between MC and ADHD; it was therefore suggested that MC could serve as endophenotype for ADHD. We examined the association between ADHD sympto...

This paper explores from a neuropsychological perspective the relation between the meanings of English locative prepositions (e.g., in, on, above, below) and the kinds of representations that are used for many visuospatial processes such as recognising, drawing, and constructing spatially complex objects. One possibility that has been proposed by some psycholinguists is that the meanings of pre...

A major goal of neuropsychological assessment is predicting a person's level of functioning in daily life. Making predictions about everyday executive functioning based on tests is problematic because of the contrast between demands made in the test environment and demands made in everyday life (Shallice & Burgess, 1991). As executive functions play an important role in independent functioning,...

OBJECTIVE To determine whether age differences exist with respect to neuropsychological and electrophysiological functioning following a sport concussion. DESIGN Cross-sectional study. PARTICIPANTS Ninety-six athletes (9-12 years, n = 32; 13-16 years, n = 34; adults, n = 30), half of whom had a sport concussion. INTERVENTION Cognitive functioning was assessed using standardized neuropsych...

Because of its reconstructive nature, autobiographical memory (AM) is subject to a range of distortions. One distortion involves the erroneous incorporation of features from one episodic memory into another, forming what are known as memory conjunction errors. Healthy aging has been associated with an enhanced susceptibility to conjunction errors for laboratory stimuli, yet it is unclear whethe...

BACKGROUND Cognitive functioning is important for managing work and life in general. However, subjective cognitive complaints (SCC), involving perceived difficulties with concentration, memory, decision making, and clear thinking are common in the general and working population and can be coupled with both lowered well-being and work ability. However, the relation between SCC and cognitive func...
