My research primarily focuses on factors that influence the nature of social information processing. For instance, when perceivers encounter social stimuli, what aspects of their attitudes, beliefs, or the social setting, influence the amount or direction of target-relevant processing? In these situations, assessment of processing is important because the consequences of the resulting perceptions should differ in critical and predictable ways. My research has explored these interests in a variety of social contexts including message-based persuasion, impression formation, and stereotyping.

Primary Interests:

  • Attitudes and Beliefs
  • Communication, Language
  • Judgment and Decision Making
  • Person Perception
  • Persuasion, Social Influence
  • Prejudice and Stereotyping
  • Social Cognition
