Faces of Intersubjectivity

Abstract

Here we consider interpersonal experience in schizophrenia, melancholia, and mania. Our goal is to improve understanding of similarities and differences in how other people can be experienced in these disorders, through a review of first-person accounts and case examples and of contemporary and classic literature on the phenomenology of these disorders. We adopt a tripartite/dialectical structure: first we explore main differences as traditionally described; next we consider how the disorders may resemble each other; finally we discuss more subtle but perhaps foundational ways in which the phenomenology of these disorders may nonetheless be differentiated. These involve disruptions of common sense and conventionality, abnormalities of empathy, distinct forms of paranoia and the sense of personal centrality, and altered perceptions of intentionality, deadness, and artificiality. We end by considering some neurocognitive research relevant to these abnormal forms of subjectivity, including work on theory of mind, experience of human movement, and perception of faces.
