Mental accounting is the set of cognitive operations used by individuals and households to organize, evaluate, and keep track of ®nancial activities. Making use of research on this topic over the past decade, this paper summarizes the current state of our knowledge about how people engage in mental accounting activities. Three components of mental accounting receive the most attention. This ®rs...

Mental disorders with pain as a leading symptom are remnat diagnostic categories for physicians and psychotherapist, even if they are educated in pain treatment. Patients with somatoform pain disorder (ICD-10: F45.4) are often diagnosed only after several years and multiple diagnostic procedures, in some cases after iatrogenic impairment. The clinical practical features, diagnostic procedure an...

We conducted a field study of 71 action teams to examine the relationship between team mental model similarity and accuracy and the performance of real-world teams. We used Pathfinder to operationalize team members’ taskwork mental models (describing team procedures, tasks, and equipment) and teamwork mental models (describing team interaction processes) and examined team performance as evaluat...

nowadays, the problem of the flexibility in any organization has essential importance and the associated investigation with the organizational efficiency and performance is considered. in real-world situation, the process of decision making is often based on linguistic and mental data, so applying fuzzy logic in modeling at this point of view is convenient. in this paper, a fuzzy approach is ap...

A new view of mental rotation in humans is presented. Rather than being a perceptual phenomenon, mental rotation of objects is supposed to be an imagined action in the sense that its only difference to real action is the absence of motor output. A series of experiments is reported which shows that the difference in speed between mental and manual rotation are negligible and that performing rota...

The manipulation of mental representations in the human brain appears to share similarities with the physical manipulation of real-world objects. In particular, some neuroimaging studies have found increased activity in motor regions during mental rotation, suggesting that mental and physical operations may involve overlapping neural populations. Does the motor network contribute information pr...

Brain-computer interface is a growing field of interest in Human Computer Interaction with divers applications ranging from medicine to entertainment. In this paper, we present a system which allows for classification of mental tasks based on a joint timefrequency-space decorrelation, in which mental tasks are measured via electroencephalogram (EEG) signals. The efficiency of this approach was ...
