Edward Thorndike suggested that: • If the results of the response is positive, the behaviour is likely to be repeated again for the situation. • However, if the results of the response is negative, the behaviour is likely to be abolished for the same situation. For example, • If the person finds that getting sufficient sleep will be able to focus on doing work well, the person is very likely to go to bed early. • However, if the person finds that not getting enough sleep will struggle to concentrate on doing work, the person will prefer not to stay up very late.
