Psychophysiology at St. Olaf College
Psychophysiology
is a part of a much larger area of science, the emerging field of
neuroscience. While the most basic definition of neuroscience is
that it is the study of the nervous system, the actual techniques
used come from all areas of science. Neuroscience incorporates aspects
of biology, chemistry, physics, psychology, computer science, and
philosophy. The necessary technology to view these phenomena is
now pushing us into the digital age, creating digital neuroscience.
Louis
Tassinary has pointed out that psychophysiology is an integrative
science. Advances in neuroscience have made it apparent that the
difference between it and more 'basic' sciences such as physiological
psychology is one of analysis; that is, the disciplines are defined
less by their reliance on a particular experimental protocol then
they are by the substantive nature of their questions - their level
of analysis. Psychophysiology provides a way to discover the reciprocal
influences of social, cognitive, and affective variables on physiological
variables. In somewhat poetic terms, Dr. Kenneth Hugdahl says that
psychophysiology is a discipline which provides a "mind-body
perspective" (1995).
Digital neuroscience is now becoming the standard in recording techniques. A machine that once took up the space of a bicycle is now transformed into something no larger then an introductory psychology text book. Students in our lab are exposed to aspects of neuroscience that, up until now, had been restricted to graduate students.
8
BIOPAC MP30s are paired with Gateway Computers to create fully digital
workstations, enabling students to participate in structured labs
or create their own research projects. Powerful software records
the input from the MP30, creating a digital file that is easily
stored. Both high school and college students soon become engaged
by seeing their data displayed in real time on the computer. It
is the mission of the St. Olaf Psychophysiology Laboratory to increase
the knowledge of digital neuroscience in high school and college
students of all levels. Students who become familiar with today's
technology will become the next generation of leaders in all areas
of science.
