What is an animal's affective state?

• A. Feelings, emotions, pain, fear, pleasure
• B. Body temperature and heart rate only
• C. Genetic makeup
• D. Nutritional status

Answer: (A)

Affective state is the animal’s subjective experience—its feelings and emotions, including pain, fear, and pleasure, as well as neutral or positive states. This concept focuses on what the animal actually feels inside, not just measurable body signals. While physiological measures like body temperature and heart rate can reflect arousal or stress, they don’t by themselves reveal the animal’s inner emotional experience. Genetic makeup outlines inherited traits, not the current emotional state, and nutritional status describes energy balance and health, not how the animal feels emotionally at the moment. In welfare assessment, we aim to infer both negative states (like pain or fear) and positive states (like pleasure or contentment) from behavior and physiology to understand the animal’s overall well-being.
