Exercise Psychophysiology Research Laboratory
Facilities
The Exercise Psychophysiology Laboratory is located in room 250 of the Louise Freer Hall. Primarily, the laboratory has a research focus, serving the needs of its staff, as well as other graduate and undergraduate students conducting research in the area of Exercise Psychophysiology as part of their graduate training in Exercise Psychology, undergraduate honors theses, supervised research experience courses, or independent study courses. In addition to its research role, the laboratory serves an educational purpose, providing hands-on experience to students enrolled in KINES 343/PSYCH 346: Psychophysiology in Exercise and Sport, a course offered by the Department of Kinesiology and Community Health each fall.
The laboratory is equipped with an array of instruments for the assessment of psychophysiological variables. For our EEG research, we use a Grass Model 12 Series Neurodata Acquisition System with 16 model 12A5 amplifiers.
For the collection of the EEG 
signals from the scalp we use stretchable lykra electrode caps, identical to the one shown above on the cover of "Newsweek." This EEG setup is used in conjunction with the EEGSYSsoftware package for storing and analyzing the digitized signals. For the study of facial EMG responses, we use a Coulbourn module frame fitted with 2 bioamplifiers and 2 contour following integrators. Furthermore, the laboratory is equipped with several Polar heart monitors, other instruments for the automated measurement of blood pressure and heart rate, as well as numerous accessory instruments.
The laboratory currently houses 6 computers with processors ranging from 486 to Pentium III, providing us with ample computing power. All 6 computers are inter-connected through the Department of Kinesiology and Community Health Local Area Network (LAN), and are also connected to the Internet via fast Ethernet links. Two of the computers are equipped with dual monitors for the simultaneous representation of psychophysiological data in graphic and textual form. Also, two of the computers are equipped with A/D boards and are used primarily for the collection of psychophysiological data. The remaining two are mainly used for data storage and analysis, as well as for the collection of self-report data. Data are stored using a variety of media, including multi-Gigabyte hard disks, two writeable CD-ROMs drive, Zip drives, and a tape streamer.
For our exercise interventions, we primarily use a Quinton ClubTrack Treadmill. When necessary (e.g., to reduce movement artifact in psychophysiological measurements taken during acute exercise), we use Monark cycle ergometers. For the assessment of the aerobic fitness of our study participants, we have access to the human biodynamics research area in the Physical Fitness Research Laboratory (PFRL). The PFRL is equipped with state-of-the-art instruments for the on-line measurement of expired gases during exercise, as well as an impressive array of other measurement and recording devices.
For the assessment of self-reported affective responses, we have developed "Data Factory", a Windows95 software program which automates the data collection process. The experimenter can specify the study protocol (the psychometric scales and questionnaires to be administered and the time intervals between administrations), and study participants respond using a UniTouch touch-screen monitor by Carroll Touch. "Data Factory" collects the responses, scores the questionnaires automatically, and saves the data in a format which can be read directly by statistical analysis software. In addition to "Data Factory", we have also developed a number of custom-made computer programs which automate and streamline the processing and analysis of psychophysiological data. For example, we have developed programs which parse and convert the output files generated by the EEGSYS spectral and coherence analysis modules to ready-to-analyze format, thus eliminating the need for manual data entry.
