J Adolesc, 26, 475-479.]) can be used to index real-world risk-taking behavior, questions remain regarding how performance on the task may vary as a function of reward/loss value and how this relationship may differ as a function of relevant personality traits. The present study examined BART score at 1, 5, and 25 cents per pump and how this relationship differed at low and high levels of impulsivity and sensation seeking. Results indicated that riskiness on the BART decreased as reward/loss magnitude increased. Further. this decrease was most prominent in those low in Impulsivity/Sensation Seeking, whereas those high in Impulsivity/Sensation Seeking were largely insensitive to variation in reward/loss magnitude. Findings are discussed in terms of sensitivity to reward and loss, and how these processes can be studied further using the BART including extensions to cognitive modeling and the measurement of neurobehavioral functioning.
