Which law of adult learning suggests that habits not reinforced are weakened?

The law of adult learning indicating that habits not reinforced are weakened is known as disuse. This concept is rooted in the understanding that learning and retention of knowledge or skills depend heavily on regular practice and application. When a learner does not frequently engage with a particular skill or piece of knowledge, the neural pathways associated with that learning can weaken over time.

In essence, for adults to retain information and maintain competencies, they need to actively use what they have learned. This principle highlights the importance of ongoing practice and reinforcement in the learning process. It serves as a reminder for instructors to not only teach concepts but also create opportunities for learners to continually engage with the material, ensuring long-term retention and skill proficiency. Understanding this principle can be crucial for developing effective training programs that facilitate sustained knowledge and skill application in real-world situations.
