Figure 2.
Illustration of the perceptual model and the response model. The perceptual model comprises three hierarchical states (x1, x2, and x3). The subject-specific parameters ω and ϑ affect the updating of the subjects' beliefs about states of the world x and are estimated from individual RS data on the basis of precision-dependent attention α(π̂1(t)) that depends on the precision of the prediction at the first level of the perceptual model. Circles represent constants; diamonds represent quantities that change over time (trials); hexagons, like diamonds, represent quantities that change in time but that additionally depend on their previous state in time in a Markovian fashion.
