Independent use of different kinds of information within a single task
It is known for some time now that there are segregated pathways within the brain for processing various kinds of visual information. That attributes such as colour and motion are processed independently is not very surprising. However I will talk about some cases in which information that one may expect to be combined appears not to be. There are cases in which information that is potentially relevant for a judgement is completely ignored. I will argue that our visual system does not strive for consistency between attributes, but rather appears to use the most suitable processing for each task, ignoring any unnecessary information, even if this is potentially useful. As a result, different aspects of a task are controlled independently on the basis of different information.
