Which statement is a limitation of psychophysiological methods?

Question

Quizplus · Accepted Answer

Psychophysiological methods rely on measuring physiological responses, such as heart rate or skin conductance, which can be affected by factors other than the psychological processes under investigation. For example, changes in physiological responding may reflect mood swings or fatigue rather than a change in the individual's emotional or cognitive state. This is a limitation of the method that researchers need to take into account when interpreting their results.
