The Dynamics of Perception, Action, & Cognition (DPAC) lab is focused on promoting a dynamical approach to perception, action, and cognition.  Our research uses the principles and tools of dynamical systems, complex systems, and ecological psychology to understand the coordination among the multiple systems and processes involved in perception, action and cognition, including: team coordination, motor coordination, coordination of physiological processes, postural control, learning and exploration, weight perception, and tool use.

Research Opportunities

We welcome undergraduate and graduate research assistants.  Our research assistants gain experience in all aspects of research, including designing experiments, collecting data, working with technical data collection equipment, and performing data analysis.  If you are interested in joining our team, then please contact either one of the faculty directors:  Dr. Eric Amazeen (eric.amazeen@asu.edu); Dr. Nia Amazeen (amazeen@asu.edu).

Dr. Eric Amazeen's research focuses on the role of bodily movements in perception and cognition to better understand how we use movement to perceive and how cognition is influenced by the dynamics of those movements. The study of weight perception has been a particularly fruitful area of study because perceiving heaviness always begins with lifting. His research has shown that perception is tied to the dynamics of lifting and the measured activity of the muscles. The foundational role of movement dynamics is evident throughout his research on motor control and coordination in both one- and two-person movements. Curriculum vitae.


Dr. Polemnia (Nia) G. Amazeen's research is directed at the understanding of behavior as a complex system in which the whole is not equal to the sum of the parts. She uses mathematical models to look for behavior patterns and general principles of coordination in teamwork, motor skills, and other perception-action-cognition phenomena.Dr. Amazeen’s research is funded by the National Science Foundation and Department of Defense. She serves on the board of directors for the International Society for Ecological Psychology and on the executive committee for the Center for Social Dynamics and Complexity (CSDC). In 2010, she co-authored Training Adaptive Teams, which earned the Jerome H. Ely best article award. Curriculum vitae

We are collaborating with quantitative psychologist, Stephen West, to develop new dynamical methods that identify the scale and time course of influence across bodily subsystems both within and across people.  Our first publication from this effort appeared in Physica A.

We celebrated 20 years in 2020 of our ongoing seminar entitled Dynamics of Perception, Action, and Cognition (DPAC).  DPAC welcomes broad participation from faculty and students from all four of ASU’s campuses.  We are proud to have never repeated a topic over these 20 years, but any participant can rattle off a list of favorites.  Two goals are to: (1) read the broad literature required by a dynamical approach to perception, action, and cognition; and (2) hone our critical debate skills.  It’s just what you imagined a graduate seminar to be.  Come join us... all are welcome!

We are committed to teaching students of all ages about the use of dynamics in psychology, and so we value community outreach to local schools, including this group of students from refugee families.
