Primarily an experimental social psychologist focusing on the interface between social cognition and close relationship processes. However, I am increasingly adopting an interdisciplinary perspective, paying particular attention to evolutionary psychology. My theoretical and research interests are tied to one central theme -- the understanding of lay social theories, or knowledge structures, and how these are causally related to cognition, emotion, and interpersonal behaviour. Current (collaborative) research projects include the study of bias and accuracy of judgments in relationships, regulation and communication in intimate relationships, and judgments and sex differences in the very early stages of mate selection
