 Next, dissociative identity disorder (DID). (We will take up hemi-neglect and anosognosia shortly.) In cases of DID, a central feature is either some pattern of reciprocal amnesia or a strong sense that another is inside (and yet still separate). This again seems to be a situation in which being conscious of some experienced objects by having the experience goes with not being conscious of others in the same body in the same way. The main difference is that the breach seems to be at a time in brain bisection cases, but can be either across time or at a time in DID cases. If so, the breakdown in unity will again consist in breakdowns of joint consciousness. The amnesia in diachronic DID has this character, clearly (and, except for the amnesia, is in line with Bayne’s (2010) switch model), but so does synchronic DID. The person and the ‘little person inside’ have no access from the inside to each other, so no common unified consciousness of experiencing, and the objects of their experience are not unified, so no common unified consciousness of contents.
