Abstract
Risk-taking in specific contexts can be beneficial, leading to rewarding outcomes. Psychosis-spectrum disorders are associated with disadvantageous decision-making on the Balloon Analogue Risk Task (BART), consistently pursuing risky rewards less than controls. However, it is unclear whether this behavior is more strongly associated with increased sensitivity to risk or decreased sensitivity to potential rewards, which are highly correlated (r=.991) in the experimental design of the BART. Additionally, previous studies have not accounted for stark between-group differences in cognitive functioning. Matching on demographic/IQ variables, we investigated whether reduced risk-taking was associated with neural activation in regions affiliated with risk evaluation or reward processing.
