The unanticipated resilience of trait self-knowledge in the face of neural damage.
This paper explores the question of what the self is by reviewing research conducted with both normal and neuropsychological participants. Findings converge on the idea that the self may be more complex and differentiated than some previous treatments of the topic have suggested. Although some aspects of self-knowledge such as episodic recollection may be compromised in individuals, other aspects-for instance, semantic trait summaries-appear largely intact. Taken together, these findings support the idea that the self is not a single, unified entity. Rather, it is a set of interrelated, functionally independent systems. In the process of reviewing neuropsychological findings, an unexpected result emerges: trait self-knowledge appears unusually robust with respect to neural and cognitive damage that render other aspects of self-knowledge dysfunctional in varying degrees.
