Dr. Gillath’s research focuses on close relationships and their underlying mechanisms. In the past few years he has investigated the psychological aspect of behavioral systems, especially the attachment, caregiving, and sexual mating systems. Dr. Gillath’s work explores the associations between a person\'s attachment style (relationship style) and goals and behaviors in the caregiving and sexual domains (e.g., ability to provide and receive compassionate care; interest in short- vs. long-term mating strategies). He is also exploring the effects of increasing people\'s sense of attachment security on their tendency to engage in prosocial behavior, their altruistic and sexual attitudes, and their goals, as well as their attentional strategies.
