In order to get a more complete picture of the person’s response it is useful to combine the measurement of behavioral and physiological data. This free white paper shows you how The Observer® XT can be used to integrate behavioral and physiological data.

Learn more about psychophysiology. Behavioral studies are often recorded with one or more cameras. One camera, for example, records an overview of the test situation while another camera focuses on the test participant as a whole or on the face for analysis of facial, emotional expressions.
