Attentional biases have been overlooked as a treatment focus in CBT practice. This pilot study examined patterns of attentional bias an OCD clinical sample with view to understanding the key mechanisms order inform assessment and intervention. It was hypothesised that individuals would demonstrate vigilance, delayed disengagement, maintenance towards OCD-related stimuli relative matched control...

Our technology laden world continues to push the limits of human cognitive performance. Human performers are increasingly expected to assume roles of passive monitors rather than active engagers of technology systems [1]. Active and physical tasks have shifted to more sedentary tasks requiring significant cognitive workload at a rapid pace. Consequently, researchers and academics alike struggle...

THERE IS A CLOSE RELATIONSHIP BETWEEN THE CIRCADIAN RHYTHM OF CORE BODY TEMPERATURE (CBT) AND THE DAILY VARIATION IN VIGILANCE, AS SHOWN by Kleitman.1 Vigilance is optimal during the circadian phase of increased CBT.2-6 Under controlled conditions, the rhythm in CBT results to a large extent from the rhythm in skin blood flow, which determines skin temperature, and the resulting heat transfer g...

BACKGROUND Attentional dysfunction is related to functional disability in patients with neuropsychiatric disorders such as schizophrenia, bipolar disorder, and Alzheimer's disease. Indeed, sustained attention/vigilance is among the leading targets for new medications designed to improve cognition in schizophrenia. Although vigilance is assessed frequently using the continuous performance test (...

The aim of this study was to determine the role played by vigilance on the anaerobic performance recorded during a Wingate test performed at the bathyphase (nadir) of the circadian rhythmicity. Twenty active male participants performed a 60-s Wingate test at 6 a.m. during 3 test sessions in counter-balanced order the day after either (i) a normal reference night, (ii) a total sleep deprivation ...

Sustained, long-term cognitive workload is associated with variations and decrements in performance. Such fluctuations in vigilance can be a risk factor especially during dangerous attention demanding activities. Functional MRI studies have shown that attentional performance is correlated with BOLD-signals, especially in parietal and prefrontal cortical regions. An interesting question is wheth...
