Self-Expansion

A majority of my work examines self-expansion, a motivation to enhance the self’s capabilities through the accumulation of knowledge, experience, identity and other resources, largely through relationships. Thus, my research program examines self-expansion and self processes in several facets of relationships: relationship initiation, attraction, relationship maintenance, susceptibility to infidelity, and break-up.

• “The Sustainable Marriage Quiz”  

Dr. Lewandowski discusses self-expansion with the Millionaire Matchmaker.

Relationship Processes

Other relationship research focuses on how learning about someone’s personality influences perceptions of their physical attractiveness, the experience of personal growth and positive outcomes following relationship dissolution, including strategies to promote positive outcomes.

Self & Identity

Another major line of research focuses on self-processes. Specifically I have focused on the benefits of self-concept clarity, or how clearly and confidently one defines the self, on how accurately a person's knows their self. The main line of inquiry, however, explores the nature and benefits of self-expansion outside of relationships. These benefits include increased effort, increased self-efficacy, and increased job satisfaction and commitment.
