Which researcher is associated with the 1986 study linking hormones to aggression in rats?

• A. Albert et al. (1986)
• B. Kiecolt-Glaser
• C. Selye
• D. Watson

Answer: (A)

The study by Albert and colleagues in 1986 is a classic example of how hormones can influence aggressive behavior in animals. They showed that manipulating hormonal levels in rats leads to measurable changes in aggression, illustrating a direct link between the endocrine system and social behavior. This fits the biological approach’s focus on how physiology underpins behavior. The other researchers are tied to different areas—Kiecolt-Glaser with stress and immune function, Selye with general adaptation to stress, and Watson with behaviorism—so Albert et al. is the best match for a hormone–aggression study in rats.
