      abstract     = {The visual system forms predictions about upcoming visual
                      features based on previous visual experiences. Such
                      predictions impact on current perception, so that expected
                      stimuli can be detected faster and with higher accuracy. A
                      key question is how these predictions are formed and on
                      which levels of processing they arise. Particularly,
                      predictions could be formed on early levels of processing,
                      where visual features are represented separately, or might
                      require higher levels of processing, with predictions formed
                      based on full object representations that involve
                      combinations of visual features. In four experiments, the
                      present study investigated whether the visual system forms
                      joint prediction errors or whether expectations about
                      different visual features such as color and orientation are
                      formed independently. The first experiment revealed that
                      task-irrelevant and implicitly learned expectations were
                      formed independently when the features were separately bound
                      to different objects. In a second experiment, no evidence
                      for a mutual influence of both types of task-irrelevant and
                      implicitly formed feature expectations was observed,
                      although both visual features were assigned to the same
                      objects. A third experiment confirmed the findings of the
                      previous experiments for explicitly rather than implicitly
                      formed expectations. Finally, no evidence for a mutual
                      influence of different feature expectations was observed
                      when features were assigned to a single centrally presented
                      object. Overall, the present results do not support the view
                      that object feature binding generates joint feature-based
                      expectancies of different object features. Rather, the
                      results suggest that expectations for color and orientation
                      are processed and resolved independently at the feature
                      level.},
