The aims of the study were to compare performance of twins with bipolar disorder (BPD) and healthy co-twins in neuropsychological tests assessing various aspects of executive functioning and to examine the relationship of clinical factors with executive functions. Twenty-six euthymic BPD twins, 19 co-twins, and 114 control twins were examined using the Stroop test, the Wisconsin card sorting te...

In this study, some executive function measures (Wisconsin Card Sorting Test [WCST], verbal fluency, and Trial Making Test [TMT], Form A and Form B) were correlated with Wechsler Intelligence Scale for Children-Revised (WISC-R) scores. Fifty 13- to 16-year-old normal children were selected. It was found that verbal fluency tests correlated about 0.30 with Verbal Intelligence Quotient (IQ) and F...

AIM The aim of the study and was the assessment of Cognitive Remediation Therapy (CRT) in an adolescent anorexia nervosa patient. METHODS CRT cognitive training was performed. Eating Attitudes Test 26 (EAT - 26), Beck Depression Inwentory (BDI), Child Yale - Brown Obsessive - Compulsive Scale (CY - BOCS), Eating Disorders Belief Questionnaire (EDBQ), Wisconsin Card Sorting Test (WCST), Temper...

UNLABELLED BACKGROUND Several lines of evidence implicate orbitofrontal cortex dysfunction in the pathophysiology of obsessive-compulsive disorder (OCD). The purpose of this study was to investigate neuropsychological dysfunction of the orbitofrontal cortex in children with OCD. METHODS The Iowa Gambling Task (IGT), which reflects orbitofrontal cortex function, and the Wisconsin Card Sorti...

The current study investigates the influence of L2 proficiency on cognitive control among three matched groups of unbalanced Chinese-English bilinguals. Flanker task was administered to measure conflict monitoring and inhibition, and Wisconsin Card Sorting Test (WCST) to measure mental set shifting. ANOVA analyses of the Flanker results showed no differences in inhibition across all groups and ...

This study aimed to compare a neuropsychological test tapping into executive control function, the Wisconsin Card Sorting Test (WCST), performed in either traditional paper-and-pencil (PP) or virtual reality (VR) modality, and determine role of human factors (i.e., sense presence, cybersickness, field (in)dependence video game experience) as contributors performance perceived mental effort. Ind...

BACKGROUND Several lines of evidence suggest that dysfunction of the dorsolateral prefrontal cortex (DLPFC) and orbitofrontal cortex (OFC) contributes to the pathophysiology of pervasive developmental disorders (PDD). The purpose of this study was to investigate neuropsychological dysfunctions in both the DLPFC and OFC of children and adolescents with high-functioning PDD. METHODS The Iowa ga...

The Wisconsin Card Sort Task (WCST) is a commonly used neuropsychological test of executive or frontal lobe functioning. Traditional behavioral measures from the task (e.g., perseverative errors) distinguish healthy controls from clinical populations, but such measures can be difficult to interpret. In an attempt to supplement traditional measures, we developed and tested a family of sequential...

The present study investigates executive functioning in schizotypic college students and control subjects using the Wisconsin Card Sorting Test (WCST). Inhibitory control and working memory, two aspects of executive functioning, were examined in deviantly high scorers on the Perceptual Aberration and Magical Ideation Scales (n=97), high scorers on the revised Social Anhedonia Scale (n=58), and ...
