B.1 Identify and distinguish among behavior, response, and response class

Behavior Is any observable and measurable action an organism performs while interacting with its environment. Examples: A child walking to the door. A person talking on the phone. A dog barking. A cat rubbing against its owner. A student thinking about an exam answer.

Response Is a single observable instance of behavior occurring at a specific moment. Examples: Raising your hand in class. Kicking a ball. Smiling. Saying "hi."

Response Class Consists of multiple responses that achieve the same effect on the environment. Examples: Paying with a debit card or cash (both result in a purchase). Calling or emailing to schedule an appointment (both result in a confirmed appointment). Locking a door with a key or chain (both block entry). Washing clothes in a washing machine or by hand (both clean the clothes).

Understanding behavior, responses, and response classes helps clarify how organisms interact with their environment and achieve their goals.
