 What is common to dysexecutive disorder, Trevarthen’s cases, and simultagnosia is that subjects seem not to be conscious of even two objects in a single conscious state. They cannot, for example, compare the objects (in Trevarthen’s cases, the object of a perception with the object of an intention). Unlike commissurotomy cases, it is not the case that a conscious experience of the second item exists within another unified consciousness. If there is any experience of the second item at all, it is not conscious. Rather than consciousness being split into two discrete parcels, there is just one diminished parcel. The rest of the conscious experiencing that is typical of normal consciousness has disappeared.
