What psychological approach is demonstrated by Tammy, who studies physiological responses like heart rate during deception?

Tammy's focus on physiological responses, such as heart rate, aligns with the Biological Approach in psychology. This approach emphasizes the importance of biological processes and physical states in understanding behavior and mental processes. By studying heart rate in the context of deception, Tammy is exploring how physiological changes correlate with psychological phenomena, which is a key aspect of the Biological Approach. This approach looks at the interplay between the body and mind, particularly how biological factors like hormones, genetics, and neural mechanisms influence thoughts and behaviors.

Other psychological approaches, such as the Behavioral Approach, focus primarily on observable behaviors and the responses to environmental stimuli, while the Humanistic Approach emphasizes personal growth and self-actualization, focusing more on subjective experiences and less on biological factors. The Psychodynamic Approach, originating from Freud's theories, concentrates on unconscious processes and childhood experiences, rather than physiological measurement. Thus, studying physiological responses during deception is distinctly characteristic of the Biological Approach.
