Curriculum Vitae

Research Interests

Paul Eastwick’s research investigates how people initiate romantic relationships and the psychological mechanisms that help romantic partners to remain committed and attached.

These two theoretical/review papers best illustrate Dr. Eastwick’s past and ongoing research:

Mate Evaluation Theory aims to explain the origin of romantic compatibility: Why do some couples “fit” together better than other couples? The theory describes how compatibility effects come in two different forms, one of which is grounded in “matching” effects of individual differences (e.g., “I like partners who fit my ideal partner preferences”), and one of which is bound to an interaction-specific history with a particular person. MET proposes that the latter (dyad-specific) source of compatibility is much larger than the former (individual-difference-matching) source. However, as the article explains, the field needs new kinds of studies to be able pull these two sources apart.

Here is a brief video tutorial on the Social Relations Model, which is core to Mate Evaluation Theory.

The Relationship Trajectories Framework attempts to bridge the ongoing disconnect between different literatures that study human mating (e.g., close relationships vs. evolutionary psychology, attraction vs. close relationships). Specifically, this meta-theoretical framework conceptualizes how human mating relationships develop across their complete time span, from the moment two people meet until the relationship ends. It also generates additional predictions that can help explain how seemingly distinct “types” of relationships (e.g., short-term vs. long-term relationships) actually derive from a core, shared set of longitudinal, mate-evaluation processes.
