Normative studies of variability in performance by healthy adults on neuropsychological batteries are reviewed. Regarding test score scatter, normative participants often have large discrepancies between best and worst scores. When "abnormality" was defined as a score more than one standard deviation below the mean, in test batteries with at least 20 measures, the great majority of normative pa...
The Tower of London (TOL) task is widely used as a neuropsychological test of planning. Relatively little is known of the cognitive components of the task, and in particular the role of memory in performance. The current studies on normal adults looked at the role of verbal and spatial working memory in the TOL. The effects of verbal and visuospatial dual-task manipulations on TOL performance w...
Thirty-two studies of commonly researched neuropsychological malingering tests were meta-analytically reviewed to evaluate their effectiveness in discriminating between honest responders and dissimulators. Overall, studies using the Digit Memory Test (DMT), Portland Digit Recognition Test (PDRT), 15-Item Test, 21-Item Test, and the Dot Counting Test had average effect sizes indicating that diss...
Cannabis use has been linked to impairments in neuropsychological functioning across a large and continually expanding body of research. Yet insight into underlying causal relations remains limited due to the historically cross-sectional nature of studies in this area. Recently, however, studies have begun to use more informative design strategies to delineate these associations. The aim of thi...
The aim of the study was to explore whether application of cognitive stimulation in young healthy subjects may improve their cognitive efficiency. The study included 12 healthy young subjects divided into two groups, experimental group and control group. Prior to cognitive stimulation treatment, both groups underwent baseline measurements with selected neuropsychological tests. The groups were ...
The frequency and determinants of abnormal test performance by normal individuals are critically important to clinical inference. Here we compare two approaches to predicting rates of abnormal test performance among healthy individuals with the rates actually shown by 327 neurologically normal adults aged 18-92 years. We counted how many participants produced abnormal scores, defined by three d...
The aim of this study was to identify cortical areas important for optimal cognitive aging. 74 participants (20-88 years) went through neuropsychological tests and two MR sessions. The sample was split into two age groups. In each, every participant was classified as "high" or "average" on fluid ability tests and on neuropsychological tests related to executive function. The groups were compare...
In clinical neuropsychology a huge number of neuropsychological tests have been developed, and the corpus of these instruments is always increasing. Because of this, the question has been raised as to which are the most usefull instruments that provide the best neuropsychological profiles of the subjects. In the actual literature, there are polemics about the advantages and disadvantages of com...
Validity of the standard, 13 subtest A Developmental Neuropsychological Assessment (NEPSY) was investigated by comparing scores for 30 children with neurological conditions, 35 children with scholastic concerns, and 39 controls. Overall differences were found among the groups with and without controlling for IQ (Lambda = .60, Lambda = .001; Lambda = .70, P < .001). Four of five NEPSY domain sco...
