40)Order effect is the prejudicial impact that the presentation order of a question, idea, answer, or product has on a respondent. Whether the item is located in the first, last, or middle position sometimes affects the selection of or response to that item. There have been several studies that have noticed an order effect when an early stimulus acts as a frame of reference for later stimuli. Robert Ferber from Illinois University had respondents rate a list of occupations and found that the maximum or minimum ratings occurred on the one presented first, regardless of the ordering of the occupations. In another study, the subjects were asked to rate a beverage on intention to buy on a scale ranging from “definitely would not buy” to “definitely would buy.” The first beverage tasted was rated significantly higher.
