BACKGROUND Alcoholics have impaired cortisol response to stress, indicating dysregulation in the extrahypothalamic systems responsible for activating cortisol secretion in response to stressor exposure. There is a growing literature indicating a relationship between hypothalamic-pituitary-adrenocortical axis activity and neurocognitive functioning. This study examined the hypothesis that dysreg...

The Wisconsin Card Sorting Test (WCST) is a set-switching task used extensively to study impaired executive functioning in schizophrenia. Declarative memory deficits have also been associated with schizophrenia and may affect WCST performance because continued correct responding depends on remembering the outcome of previous responses. This study examined whether performance in visual and verba...

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...

Although there are several studies on the effects of mental fatigue on task performance, still much is unknown about the cognitive processes that underlie performance deficits under fatigue. In the current study we test the idea that behavioral manifestations of mental fatigue may be linked to compromised executive control. Executive control refers to the ability to regulate perceptual and moto...
