Paul Ekman and the search for the isolated face in the 1960s.

This essay examines the detailed process of isolating facial data from the context of its emergence through the early work of psychologist Paul Ekman in the 1960s. It explores how Ekman's data practices have been developed, criticized, and compromised by situating them within the political and intellectual landscape of his early career. This essay follows Ekman's journey from the Langley Porter Neuropsychiatric Institute to New Guinea, highlighting his brief but notable collaborations with psychologist Charles E. Osgood and NIH researchers D. Carleton Gajdusek and E. Richard Sorenson. It argues that the different meanings assigned to the human face resulted in how each group developed their studies - examining facial expressions either in interaction, where they shape reciprocal actions in interpersonal communication, or in isolation, where faces surface from the individual's unconscious interior.
