Structure Learning in Bayesian Sensorimotor Integration
Fig 4
Performance of all participants in the last session of the experiment.
The performance in the horizontal dimension is shown in panel A, performance in the vertical dimension in panel B. Performance is measured by slopes as in Fig 3 comparing no-feedback trials (purple) and partial feedback trials (yellow and cyan). Learning of the correlation structure is evident whenever the slope in the uninformative dimension of the partial feedback trials is significantly smaller than the slope in no-feedback trials (see also Fig 3). The perfect Bayesian response for no-feedback trials is characterized by a slope of one indicated by the thin black line, the Bayes-optimal slope for partial feedback trials would be zero—assuming that the Bayesian actor perfectly knows the statistics of the task. In both panels, error bars show standard errors of the robust fit.
