Response
Feedback: Physiological measures include two categories, biophysical and
biochemical measures. For example, biophysical measures might include
the use of the stethoscope and sphygmomanometer to measure blood
pressure and a biochemical measure might include the laboratory value
for total cholesterol. Self-report has been used effectively to obtain
physiological information and may be particularly useful when the
subjects are not in closely monitored settings such as hospitals, clinics, or
research facilities. For some variables, self-report may be the only means
of obtaining the information. Such may be the case when study
participants experience a physiological phenomenon that cannot be
observed or measured by others.
