Thorndike's 'Law of Exercise', one of the primary laws of learning, was later subdivided into which two sub-laws, and its theoretical alignment is most closely associated with which concept of B. F. Skinner?

Edward Thorndike's primary Law of Exercise is divided into two sub-laws: the Law of Use and the Law of Disuse.

Key Concepts

• Law of Use: States that connections between stimulus and response are strengthened with practice, aligning closely with B. F. Skinner's concept of Reinforcement.
• Law of Disuse: States that connections weaken when practice is discontinued, which parallels Skinner's concept of Extinction.

Therefore, option (b) is the correct and most precise academic alignment regarding Thorndike's connectionist theory and Skinner's operant conditioning.
