Ventromedial prefrontal cortex lesions iowa gambling task

By Admin

Ventromedial prefrontal cortex (VMF) damage can lead to impaired decision-making. This has been studied most intensively with the Iowa gambling task (IGT), a card game that asks subjects to overcome an initial attraction to high-payoff decks as losses begin to accrue. VMF subjects choose from the high risk decks more often than controls, but ...

PDF | Prior research suggests that the Iowa Gambling task is performed poorly by individuals with lesions in the ventromedial prefrontal cortex (VMPFC). The current study investigated whether ... Contribution of different regions of the prefrontal cortex ... More precisely, our lesion analysis revealed that decision-making processes depend on a large cerebral network, including both ventromedial and dorsolateral areas of the prefrontal cortex. Consistent with past findings, our results support the claim that IGT deficit is not solitarily associated with ventromedial prefrontal cortex lesions. Failure to Learn from Repeated Mistakes: Persistent ...

Ventromedial prefrontal cortex lesions were also associated with a deficit in processing gender specific social cues. One experiment tested the ability of patients with vmPFC lesions to categorize gender-specific names, attributes, and attitudes compared to patients with dorsolateral prefrontal cortex lesions and control subjects.

Risk aversion (psychology) - Wikipedia Researching decision-making and affect, Antoine Bechara, Antonio Damasio and colleagues (2000; 2005) discovered that damage to a brain area associated with emotional processing impairs effective decision-making. [18] [19] After discovering … Thinking like a trader selectively reduces individuals' loss…

Abstract. The somatic marker hypothesis proposes that decision-making is a process that depends on emotion. Studies have shown that damage of the ventromedial prefrontal (VMF) cortex precludes the ability to use somatic (emotional) signals that are necessary for guiding decisions in the advantageous direction.

Previous studies of patients with vmPFC lesions have focused primarily on decision-making under uncertainty, when outcome probabilities are ambiguous (e.g. the Iowa Gambling Task).
