Stoffregen & Bardy's target article is based on the assumptionthat our senses' ultimate purpose is to provide us with perfectinformation about the outside world. We argue that it is often moreimportant that information be available quickly than that it beperfect. Consequently our nervous system processes different aspectsof information about our surrounding as separately as possible. Theseparation is not between the senses, but between separate aspectsof our surrounding. This results in inconsistencies betweenjudgments: sometimes because different frames of reference are used.Such inconsistencies are fundamental to the way the information ispicked up, however, and hence cannot be avoided with clearerinstructions to the subjects.
