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.},
