Connectionism is a learning theory based on the concept of bonds formed between stimulus and response. That is natural connections between situations (S) and responses (R) are formed and strengthened. The stimulus affects the organism which responds to it.
According to Thorndike, learning consists of bond formation which means that connection between situations and responses is strengthened through learning. This theory of learning also explains that the bonds between situations and responses are strengthened by satisfaction and weakened by annoyance.
Thorndike's Law concerns the role of reward in learning. It is known as the Law of Effect, because whether a response would be stamped in or stamped out depends upon the effect such a response produces.
Thorndike’s Law of Exercise concerns the role of practice in learning. It states that the strength with which a response will be connected with a situation depends upon the number of times the response has occurred in that situation.
