Which statement best defines magnitude in the context of an animal's internal state?

• A. The duration of the state
• B. The number of times the state occurs
• C. How much or how strongly the animal experiences that state
• D. The location of the state

Answer: (C)

Magnitude is about how intense the internal state is—the degree to which the animal experiences it. It captures the strength or level of the feeling at a given moment. For example, hunger can be mild or strong, and fear can be a slight unease or a pronounced panic. This helps explain welfare impact because higher intensity states typically signal a greater disruption to well-being.

Duration describes how long the state lasts, frequency describes how often it occurs, and location refers to where in the body or brain the sensation is felt. These aspects are related but separate from the strength of the experience.
