Teaching Interests

As a developmental psychologist, I teach child and adolescent development, gender development and a seminar on the developmental understanding on inclusion and exclusion. I also teach interpersonal psychology, which is grounded in the development of self and relationships with others. I enjoy teaching introductory psychology as well as methodology courses.

My role of professor at Muhlenberg has many rewards and challenges. It is rewarding to watch my students make connections between the course objectives and everyday life circumstances. They often rise above and beyond my expectations. I find it important to continue to find new and interesting ways to present material. I believe that learning within a liberal arts setting is a process for both students and teachers and that by working together we can question, analyze and expand our knowledge and interest in psychology and in the world around us.

Research, Scholarship or Creative/Artistic Interests

My research training and expertise are in the area of social and moral development, with a focus on children’s and adolescents' social reasoning in everyday contexts.

My three main lines of research focus on:

  1. Inclusion and exclusion in social contexts.
  2. How social reasoning is influenced by stereotypes.
  3. How children and adolescents come to understand the processes of inclusion and exclusion as it is affected by both individual and group categorization.

My lab is involved in two main areas of research: examining gender roles, stereotypes and discrimination; and examining distributive justice (the socially just allocation of goods and privileges in a society) and economic inequality.

I also have a strong interest in the psychology of teaching and learning, the teaching of interpersonal skills in the classroom and the increased importance of information literacy in understanding psychological research and the representation (or misrepresentation) of psychology in the popular press.
