Stimulation generalization refers to the formation of conditional organisms that have learned to respond specifically to a certain stimulus, so they can also respond to similar stimuli in the same way. Stimulation differentiation is to make the organism through selective strengthening and regression. Learn to react differently to conditioned stimuli and stimuli similar to conditioned stimuli. Based on the above definition, the following statements are incorrect:. ['"Once bitten by a snake, ten years of fear of good ropes" is a generalization of stimulus.', '"Looking into the ridge side to the peak, different in height and distance" belong to stimulus differentiation.', 'In order to highlight the brand, the manufacturer uniquely designs the packaging to try to make customers differentiate.', 'After a brand of toothpaste becomes a famous brand, the manufacturer also names the cosmetics it produces under the same brand, using the generalization of customer stimulation.']
