A statement that “sticks out like a sore thumb” is more likely to be recalled than other statements is what is meant by the Von Restorff effect, also known as the isolation effect. A person will be more likely to recall the item that is highlighted in bright green on a shopping list than any of the others, for instance. Hedwig Von Restorff discovered the Von Restorff effect in 1933. After a series of memory tests using isolated and unique things, she came to the conclusion that an isolated item would be more easily recalled than an item at the same relative position in a list of identical items. When someone wants remind something then make it stand out. Because a unique item attracts the attention of a subject, it tends to draw attention away from the other items being presented. Therefore, while the one object that stood out will likely be remembered long after all the stimuli are gone, the subject will remember less overall. These unique items may simply be semantically or physically unrelated to other stimuli, like a bright green word on a list of words in black ink or a picture of a musical instrument among a bunch of animal photos, or they may be bizarre or humorous. Sometimes these items are not patently distinct at all, but simply more immediate to the subject. The paper consists of the physiological feelings of the customers of how they react to a product or service which is unique from all other products. The research study reveals the psychological impact of the customers and their behavioral measure towards the purchase decision based on the effectiveness in the brand advertisement and the exposures gained through it.
