NEUROSCIENCE The effects of stress on aversive and appetitive conditioning and reversal ABSTRACT In this line of studies, we are examining how acute stress influences the way in which participants learn to assign aversive or appetitive value to...
More infoThe bounded log-odds model of frequency and probability distortion
NEUROSCIENCE The bounded log-odds model of frequency and probability distortion ABSTRACT People systematically distort probability and frequency information in decision-making and in many other perceptual, motor and cognitive tasks. We show that...
