| DPAC is a multidisciplinary research team whose focus
is the application of nonlinear dynamics, complex systems, and ecological
psychology to the fields of perception, action, and cognition. Activities
include: faculty and student lectures on theory and research; research
collaboration and grant proposal evaluation; the development of a multidisciplinary
dynamics curriculum; group mentoring of students; and student-run tutorials
on computer programming, methodology, and equipment.
DPAC provides a peer atmosphere for scientists who are based in different
departments at Arizona State University and hosts external visitors to
foster ties with the greater scientific community. Though comprised
primarily of professors and students in the areas of psychology, exercise
science and mathematics, DPAC is open to interested individuals from all
fields.

 ynamics
is the study of generic patterns of change in natural systems.

 erception
The ecological and dynamical approaches to perception and action are being
explored in this lab. This research program involves the investigation
of situations in which perception and action occur together. Specific
examples include the perception of weight by touch, the dissociation between
vision for perception and vision for action, the role of visual attention
in coordination dynamics, and the visual control of catching.

ction is the change in behavior over time.
This makes it very suitable to study using the tools of nonlinear dynamics.
We study coordination: in able-bodied and special populations;
within the motor subsystem and across physiological subsystems of the body;
as it is constrained by psychological factors, properties of the limbs,
and external task requirements; and as it changes during development and
learning.

Cognitive
performance, like all behavior, can be studied and understood from the
perspectives of complexity theory and nonlinear dynamics. From these
perspectives, performance emerges to satisfy constraints inherent in a
person's history and current context.
