The basic principles of gradual acquisition, extinction, stimulus generalisation, and discrimination apply to both classical and operant conditioning. These principles describe how organisms learn to associate different stimuli and responses or behaviors through reinforcement and punishment. These principles are applicable to both humans and animals, and are used in various setting such as education, therapy, and training.
