I am a social psychologist with strong interests in group and individual differences. Most of my research concerns nonverbal communication, studied within the following broad topic areas: measurement of accurate interpersonal perception, including accuracy of decoding states and traits as well as recall of appearance and behavior, and exploration of the correlates of such accuracy; gender differences in nonverbal communication, including both accuracy, expression skill and specific behaviors; the relation of the broad dominance construct (including status, power, etc.) to nonverbal skill and nonverbal communication; and the verbal and nonverbal behavior of physicians and patients in medical visits, with focus on gender differences and correlates of patient outcomes such as satisfaction and adherence to medical regimens.
