Fig. 3: Mouse-tracking results: stochastic task.
From: Mouse tracking reveals structure knowledge in the absence of model-based choice
a Ballistic mouse trajectories in the stochastic task. Each colored line represents the average cursor path between a top fractal and a bottom fractal for a specific transition probability (yellow = 0.9, green = 0.8, light blue = 0.7, dark blue = 0.6). For illustration, we only present the paths between fractals on the same side of the screen, in cases where subjects’ predictions were correct. We only measure the cursor’s starting point and the point at which it crosses the line, connecting those two points with a straight line. b Individual subject estimates in the stochastic task. In blue: distance towards the correct (common transition) side of the screen (in pixels), in increasing order (error bars represent s.e.m. based on N = 400 trials for each subject). In orange: inverted regression-coefficient measure of model-based behavior from Fig. 2a-c (in arbitrary units, with positive values denoting more model-based behavior, errors bars represent standard error of the regression coefficient of each individual subject based on N = 400 trials). Source data are provided as a Source Data file.
