April | 2009 | Brainethics In the article entitled Differential effects of insular and ventromedial prefrontal cortex lesions on risky decision-making, the researchers compared patients with lesions to vmPfC and the insula to healthy controls and lesion controls on … Frontiers | The chronometry of risk processing in the human… The neuroscience of human decision-making has focused on localising brain activity correlating with decision variables and choice, most commonly using functional MRI. Poor temporal resolution means these studies are agnostic in relation to … Emotion and Rationality: A Critical Review.pdf | Affect…

The task was originally presented simply as the Gambling Task, or the "OGT". Later, it has been referred to as the Iowa gambling task and, less frequently, as Bechara's Gambling Task. The Iowa gambling task is widely used in research of cognition and emotion. A recent review listed more than 400 papers that made use of this paradigm. Differential effects of insular and ventromedial ... The ventromedial prefrontal cortex (vmPFC) and insular cortex are implicated in distributed neural circuitry that supports emotional decision-making. 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). Ventromedial prefrontal cortex - Wikipedia 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.

The ventromedial prefrontal cortex (vmPFC) is a part of the prefrontal cortex in the mammalian brain.The ventral medial prefrontal is located in the frontal lobe at the bottom of the cerebral hemispheres and is implicated in the processing of risk and fear. Somatic Markers Hypothesis (Antonio Damasio) | Psynso The Iowa Gambling Task upholds this evolutionary theory by demonstrating that lesions to the ventromedial prefrontal cortex act as a blockade to the emotional decision-making signals that have evolved help humans make quick and beneficial decisions. Construct Validity of the Iowa Gambling Task Construct Validity of the Iowa Gambling Task The Iowa Gambling Task (IGT) was created to assess real-world decision making in a laboratory setting (Bechara et al. 1994). Individuals are given $2000 to start, and are told to maximize profit over the course of 100 trials by selecting cards from one of four decks. On each draw, Decks A and
