Human Psychophysiology Laboratory

Welcome to the Human Psychophysiology Laboratory web page.  I am
Dr. Joel Ellwanger, the lab founder and director.  Research pursued
in my lab examines the interrelationships between  psychological and
physiological aspects of behavior. The physiological measures used
in the lab include electroencephalogram (EEG) and event-related
potential (ERP) measures of brain activity, pupil size (pupillometry),
skin conductance, and startle eyeblink reflex modification.  The
focus of my research program includes: 1) studies characterizing
information processing deficits and biases in special populations
(trauma survivors, schizophrenia patients, chronic pain patients)
and examining what role information processing deficits and biases
play in psychological disorders, 2) studies examining the use of
psychophysiological measures in assessing eyewitness recognition,
deception, and simulation of cognitive deficit, and 3) studies of
emotion and emotional aspects of social evaluation.

Student trainees in the Human Psychophysiology Laboratory are
recruited based on their interest in pursuing graduate studies and
research careers in  psychology.  Student assistants receive
training in psychophysiological data collection and analysis
methods.  Students actively contribute to all aspects of  research
projects conducted in the laboratory and participate in the
presentation of research findings at  professional conferences.
Students also receive mentoring in the process of applying to
graduate school.  Students in the lab are encouraged to consider
applying to programs at CSULA that provide financial support for
research training of  undergraduate and graduate students such as
