Recent neurophysiological studies in macaques identified a network of brain regions related to vibrotactile working memory (WM), including somatosensory, motor, premotor, and prefrontal cortex. In these studies, monkeys decided which of two vibrotactile stimuli that were sequentially applied to their fingertips and separated by a short delay had the higher vibration frequency. Using the same ta...
Recent work has suggested an association between the orbitofrontal cortex in humans and practical decision making. The aim of this study was to investigate the profile of cognitive deficits, with particular emphasis on decision-making processes, following damage to different sectors of the human prefrontal cortex. Patients with discrete orbitofrontal (OBF) lesions, dorsolateral (DL) lesions, do...
The degree of confidence in one’s choice or decision is a critical aspect of perceptual decision making. Attempts to quantify a decision maker’s confidence by measuring accuracy in a task have yielded limited success because confidence and accuracy are typically not equal. In this paper, we introduce a Bayesian framework to model confidence in perceptual decision making. We show that this model...
aim: it seems that positive outcomes resulting from the autonomy in the job, is dependent on a number of factors. autonomy means the interdependence and freedom of staff in planning and organizing work and it has different levels. the aim of current research is to investigate the role of task reflection in relation of autonomy and skill utilization. method: the research sample consisted of 324 ...
Recent studies have argued that deficient decision making under stress is due to adoption of a hypervigilant style of decision making, which has been characterized as disorganized and inefficient. However, under the conditions that characterize many real-world or naturalistic tasks, a hypervigilant pattern of decision making may be adaptive, because the decision maker does not have the luxury o...
BACKGROUND Although decision-making processes have become a principal target of study among addiction researchers, few studies have specifically examined decision-making among individuals with alcohol dependence (AD) and findings to date are mixed. The present study examined the relationship between AD and decision-making, and tested whether different facets of antisocial and psychopathic trait...
Neurodegenerative patients show often severe everyday decision making problems. Currently it is however not clear which brain atrophy regions are implicated in such decision making problems. We investigated the atrophy correlates of gambling decision making in a sample of 63 participants, including two neurodegenerative conditions (behavioural variant frontotemporal dementia - bvFTD; Alzheimer'...
