When a certain conditioned stimulus leads to a conditioned response repeated over time, it is developed a tendency to respond in the same way when a similar stimulus is given. Because we generalise the stimulus to give a similar response, "generalisation" is the name given to the mental process that makes this phenomenon to happen.
