I study attitudes - a fundamental process in behavior regulation and decision making. Specifically, I focus

on how evaluations of individuals, social groups, and consumer products are established and changed. I examine three pathways via which people can form new, or update their existing, attitudes, judgments, and decisions:


The ‘Experience’ pathway (e.g., evaluative conditioning and approach-avoidance) 


The ‘Observation’ pathway (e.g., social learning) 


The ‘Verbal’ pathway (e.g., instructions and persuasion)
