The theory that proposes that all learning consists primarily of the strengthening of the relationship between the stimulus and the response.
In developing this theory, Thorndike proposed three laws: the law of effect, the law of exercise, and the law of readiness.
Law of Exercise: The second law of learning is the ‘Law of Exercise’ according to Thorndike’s S-R Bond Theory, which means that drill or practice helps in increasing efficiency and durability of learning and, the connections are strengthened with trial or practice and the connections are weakened when trial or practice is discontinued.
The ‘law of exercise’, therefore, is also understood as the law of use and disuse’ in which case connections or bonds made in the brain cortex are weakened or loosened. this needs exercise and repetition of various movements and actions May times.
Many examples of this are found in the case of human learning. Learning to drive a motor car, typewriting, singing or memorizing a poem or a mathematical table, and music, etc.
