Professor Lyra Stein studies personality correlates of learning and performance. The interaction of individual differences and environmental variables can have a profound effect on performance, especially in the workplace. In addition, personality can be very fluid and not wholly defined by traits. It is important to distinguish between inherent differences and the fluidity of personality states. Professor Stein teaches classes which integrate psychological science into different areas of psychology. She believes that the best manner in which to teach psychological concepts is to have students discover the concepts for themselves. She also teaches a class called myths and misconceptions in psychology which uncovers the myths of conventional wisdom in psychology.
