Abstract

Deficits in decision making comprise the core of various psychiatric disorders, The cognitive processes underlying decision making would encompass a wide range including impulse control, risk taking, harm avoidance, novelty seeking, reward dependence, and quality of choice.In recent years, different groups of researchers, from various fields of neuroscience, have attempted to develop experimental tasks in order to examine the cognitive processes involved in decision making. One of the best known examples among others is being Gambling Task (GT). First introduced in 1999, GT has been used to assess cognitive impairments in patients with brain damages, and also to evaluate the cognitive deficits seen in people with obsessive-compulsive disorder, schizophrenia, mood disorders, amyotrophic lateral sclerosis (ALS), and in professional gamblers as well.Authors of this paper have designed a new version of GT seeking to provide novel capabilities with more precision in the evaluation of decision making process. Preliminary studies using these new and other versions of GT in groups of Iranian populations showed a unique pattern of decision making which was totally different from many other studies among western people. It seems that Iranian people are being more sensitive to the number rather than the amount of losses.In addition to GT, other tasks have been developed as well to assess the processes of decision making, including Rogers' Decision Making Task (RDMT), Delayed Discounting Procedure (DDP), Delayed No matching to Sample (DNMS), Gehring's Task, and many others. Such studies have identified the role of specific brain regions, especially prefrontal cortex, in the cognitive process of decision making.
