Webb24 feb. 2024 · Behavioral Reward Responsiveness The PRT [ 2 ], a laboratory-based task grounded within signal detection theory, assesses an individual’s ability to modulate behavior on the basis of rewards. Participants completed three 100-trial blocks in which they were asked to discriminate between two perceptually similar stimuli. WebbThese optimal values vary as a function of response-stimulus interval, prior stimulus probability, and relative reward magnitude for correct responses. We tested the resulting quantitative predictions regarding response time, accuracy, and response bias under these task manipulations and found that grouped data conformed well to the predictions of an …
