Janet Polivy
Psychologist at the University of Toronto and long-standing collaborator of Peter Herman on restraint and the outside regulation of eating. Co-author of the 2003 review of how the presence of others affects food intake.
Who they are
Polivy's research with Herman over several decades concerns why people start and stop eating, and in particular how much of that is governed by cues outside the body rather than by hunger and fullness. That programme is the reason the 2003 review reaches for social rules as its explanation.
It is a three-author paper, and this page credits Herman as first author without guessing at who contributed what.
Key papers
Herman, C. P., Roth, D. A., & Polivy, J. (2003). "Effects of the presence of others on food intake: a normative interpretation." Psychological Bulletin, 129(6), 873-886. Third author.
Key ideas
When fullness is unclear, people take their stopping rule from the situation. See Inhibitory Norms.
The presence of others can raise or lower intake, depending on what that presence signals. See Social Facilitation.
