What role do hormones and neurotransmitters play in behavior according to the biological approach?

• A. They have a significant impact
• B. They have no impact
• C. They only affect digestion
• D. They completely determine personality

Answer: (A)

In the biological approach, behavior is explained in terms of brain and body biology, with hormones and neurotransmitters acting as the chemical messengers that shape how we think, feel, and act. Neurotransmitters like dopamine, serotonin, and others influence mood, motivation, learning, and impulse control by modulating neural activity in key brain circuits. Hormones such as adrenaline, cortisol, and testosterone affect arousal, stress responses, and longer-term changes in behavior by altering physiological states and brain function. Because these chemical processes directly drive neural communication and bodily responses that underlie behavior, they have a significant impact. They don’t operate in isolation or determine personality on their own, and while some hormones affect digestion, their influence extends far beyond that, into emotion, cognition, and behavior.
