Schematic illustration of the probabilistic choice model. The participant’s perceptual choice is modeled with four predictors: (1) the current stimulus duration ( β curr _ stimulus ), (2) the previous stimulus duration ( β prev _ stimulus ), (3) the previous choice ( β prev _ choice ), and (4) the baseline bias ( β 0 ). Black stems on the stimulus and choice axes depict the stimulus durations and choices, respectively. The current stimulus duration (on trial t ) is marked by a black dashed box. The stimulus duration and choice from the previous trial ( t -1) are marked by orange and blue dashed boxes, respectively. The linear combination (z) is passed through a logistic function to yield the probability for choosing longer, P(L) on trial t
