Research Interests:

Dr.Metzger’s specialty is the application of systems dynamics to understanding psychological processes, including intellectual development, developmental disorders, and patterns of judgment under uncertainty. She taught courses in data analysis, psychology of judgment, and nonlinear dynamics in psychology, she has supervised research for advanced degrees for Ph.D. students.

Research Grants:

Dr. Metzger’s research has been supported by grants from the National Science Foundation and from the Fulbright Foundation.

She was a member of the Editorial Board for the Nonlinear Dynamics in Psychology and Life Sciences (vols. 1997-2000).

She was secretary of the Society for Chaos Theory in Psychology and Life Sciences (1998-2005).

She has also been active in other professional associations and has participated in their development of electronic media .
