My Research
Despite the injunction 'Don't judge a book by its cover', considerable research demonstrates consensual first impressions of others' psychological traits based on facial appearance. Ongoing research in my laboratory addresses four questions concerning this phenomenon: 1) what are the facial qualities that influence trait impressions? 2) why do perceivers respond as they do to these particular facial qualities? 3) what are the social and psychological consequences of judging others by their appearance? 4) what are the neural mechanisms for appearance-based impressions? This work has been guided by a model of appearance-trait relationships that specifies four possible developmental paths to actual relationships between facial appearance and psychological traits as well as a set of overgeneralization hypotheses, each of which specifies an adaptive basis for forming particular impressions of faces based on their resemblance to faces for which those impressions are accurate (Zebrowitz, 1997; Zebrowitz & Montepare, 2006; 2008).
Four possible developmental paths to actual relationships between facial appearance and psychological traits include biological causes of both, environmental causes of both, traits causing appearance, and appearance causing traits via its impact on the social environment. Insofar as appearance and traits are related due to the impact of appearance on the social environment, there is a need to explain the origin and nature of such an impact. One possible mechanism is provided by the overgeneralization hypotheses, which specify particular configurations of physical qualities that will give rise to behavioral expectations and that may create true relationships between appearance and traits via self-fulfilling (or self-defeating) prophecy effects. According to the overgeneralization hypotheses, the evolutionary and social importance of detecting attributes like emotion, age, identity, or genetic fitness has created a strong tendency to respond to the facial qualities that reveal these attributes that is overgeneralized to people whose faces merely resemble a particular emotion, age, identity, or level of fitness. We are currently using connectionist modeling and fMRI methods to test the overgeneralization hypotheses, which have relevance for age, sex, and race stereotypes.
