We relate performance on the Iowa Gambling Task (IGT), a widely used, but complex, neuropsychological task of executive function in which mixed outcomes (gains and losses) are experienced together, to performance on a relatively simpler descriptive task, the Cups task, which isolates adaptive decision making for achieving gains and avoiding losses. We found(More)
Do decisions about potential gains and potential losses require different neural structures for advantageous choices? In a lesion study, we used a new measure of adaptive decision making under risk to examine whether damage to neural structures subserving emotion affects an individual's ability to make adaptive decisions differentially for gains and losses.(More)
Making a risky decision is a complex process that involves evaluation of both the value of the options and the associated risk level. Yet the neural processes underlying these processes have not so far been clearly identified. Using functional magnetic resonance imaging and a task that simulates risky decisions, we found that the dorsal region of the medial(More)
Risky decision-making is significantly affected by homeostatic states associated with different prior risk experiences, yet the neural mechanisms have not been well understood. Using functional MRI, we examined how gambling decisions and their underlying neural responses were modulated by prior risk experiences, with a focus on the insular cortex since it(More)
Several lines of functional neuroimaging studies have attributed a role for the insula, a critical component of the brain's emotional circuitry, in risky decision-making. However, very little evidence yet exists as to whether the insula is necessary for advantageous decision-making under risk, specifically decisions involving uncertain gains and losses. The(More)
Human decision-making involving independent events is often biased and affected by prior outcomes. Using a controlled task that allows us to manipulate prior outcomes, the present study examined the effect of prior outcomes on subsequent decisions in a group of young adults. We found that participants were more risk-seeking after losing a gamble (riskloss)(More)
Affective neuroscience has helped guide research and theory development in judgment and decision-making by revealing the role of emotional processes in choice behavior, especially when risk is involved. Evidence is emerging that qualitatively and quantitatively different processes may be involved in risky decision-making for gains and losses. We start by(More)

Consumer impulsivity accounts for a large percentage of purchases yet this aspect of personality is measured with a variety of instruments. Three studies were conducted to examine how measures of consumer impulsiveness relate to each other, other measures of trait level impulsivity, and a variety of decisions and judgments. These studies looked at the(More)

The effects of mindset abstraction on memory-based consideration set formation." 1 ABSTRACT Consideration set formation has been suggested as an important decision-making stage prior to choice. The current research focuses on consideration sets in the memory-based choice context and addresses the gaps in the(More)
