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

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 the Minority Opportunities
in Research (MORE) programs
