Which principle indicates that information acquired last is generally remembered best?

The principle that states information acquired last is generally remembered best is known as the Principle of Recency. This psychological concept is tied to the way our memory works, particularly in relation to the sequence in which information is presented. It suggests that items or information that are encountered more recently are often recalled more easily than older information.

In educational and training contexts, this principle emphasizes the importance of reinforcing newly learned material to ensure it is retained. For example, in the context of police training, instructors might design their curriculum to revisit critical concepts towards the end of a session, knowing that the last pieces of information presented can have a stronger impact on the learners' retention.

The other options represent different concepts. The Principle of Review emphasizes the importance of revisiting material to enhance retention, while the Principle of Readiness focuses on the learner’s state of preparedness to absorb information. The Law of Use and Disuse relates to how skills and information may fade if not practiced. Each of these principles plays a role in the learning process, but the Principle of Recency specifically highlights the effect of the timing of information acquisition on memory recall.
