Stable measures of psychological functioning require a considerable period of abstinence. However, the duration of inpatient detoxification programs has decreased dramatically in most health care systems, posing a novel challenge for clinical evaluation of patients. The present study was carried out to examine whether factors predicting short-term prognosis can be identified in alcohol dependen...

Executive function is a fundamental component of the human cognitive architecture. Here, we investigate the relationship between executive function and scientific reasoning. Eighth graders completed measures of three executive functions (EFs): shifting, inhibiting, and updating. They also completed a measure of cognitive flexibility, the Wisconsin Card Sort Task (WCST), that has predicted scien...

OBJECTIVE We assessed the correlation between the deficits of cognition, movement, and brain activity in children with Attention Deficit Hyperactvity Disorder (ADHD). METHOD We recruited 15 children with ADHD and 15 age- and sex-matched healthy control participants. Clinical symptoms, cognitive shifting, movement shifting, and brain activity were assessed using the Korean ADHD Rating Scale, t...

Severity of opioid dependence, and performance on two successive runs of the Wisconsin Card Sorting Test (WCST), were assessed in 39 right-handed male and female methadone patients who had been randomly assigned to either a recently dosed (n=21) or 24 hr abstinent (n=18) condition. Results indicated that severity of opioid dependence was positively correlated with perseverative responses and er...

OBJECTIVE To explore the relationship between regional cerebral blood flow (CBF) and cognitive function in obsessive-compulsive disorder (OCD). METHOD Single-photon emission computed tomography (SPECT) was performed for 139 OCD patients and 139 controls, and the radioactivity rate (RAR) was calculated. Cognitive function was assessed by the Wisconsin Card Sorting Test (WCST). RESULTS The RA...

1 The Wisconsin Card Sort Task (WCST) is a commonly used neuropsychological test of 2 executive or frontal lobe functioning. Traditional behavioral measures from the task 3 (e.g., perseverative errors) distinguish healthy controls from clinical populations, but such 4 measures can be difficult to interpret. In an attempt to supplement traditional measures, 5 we developed and tested a family of ...
