Discussion
Eich et al. discussed the results in terms of their initial hypotheses
that interpersonality amnesia would be obtained in the personality-specific,
word-stem completion implicit memory task and that interpersonality priming
would be obtained in the general, data-driven picture-fragment completion
implicit memory task.
Although the authors stated that their research does not directly address
the question of whether DID is a "real" disorder, it seems hard to believe
that a person "faking" DID could suppress one form of implicit memory and
not another form. As well, the concept of implicit memory implies
that it is information that is not even consciously or explicitly available
to the person. So how could someone suppress memory he/she isn't
even aware of?
Eich et al. raised the question of how DID might impair memory but did
not speculate further. Research on memory impairments in people with
DID could, however, shed light on the relative amount (or lack) of overlap
among different types of memory.
It also seems that psychologists could use the findings of this research
as an aid in diagnosis of DID. Given the great number of new cases
of DID that have been diagnosed and the controversy over whether DID is
a real mental disorder, the simple tasks designed by Eich and his colleagues
could be used in clinical settings.
