Dyads composed of unacquainted females watched a video while snacking on pizza. Their extraversion and self-monitoring scores were used to predict the extent to which individuals within dyads matched each other's food intake. Matching of intake was high irrespective of the personality composition of the dyad. We consider elements of the situation that enhanced matching and whether personality might moderate matching effects.
