Which law states that practice improves performance and retention?

• A. Law of Effect
• B. Law of Exercise
• C. Law of Readiness
• D. Law of Recency

Answer: (B)

Repeated practice strengthens what you learn, making performance smoother and memory stronger over time. When you drill a skill or recall information again and again, the connections in your brain between cues and responses become more efficient, so you can perform the action more fluently and retain it longer. This is why practice is described as improving both how well you do something and how well you remember it later.

The other ideas focus on different aspects: the Law of Effect emphasizes rewards or punishments guiding whether a behavior repeats; the Law of Readiness is about the learner’s willingness and mental set to engage in learning; and the Law of Recency highlights that things learned most recently are easiest to recall.
