Program to Provide Free Tutoring
The university has announced that starting with the fall semester, free tutoring will be available to all new students for their entire first year. The academic dean, James Maxwell, commented, “The university is aware of the academic problems that many first-year students face when making the transition from high school to college.” The new tutoring program, he said, is designed to assist first-year students who want or need additional support with their academic course work. The program will also be organized so that individual students can arrange to work with tutors majoring in their own chosen field of study.

Task3：
The Familiarity Principle
阅读材料
The Familiarity Principle
People tend to develop a preference for things they have previously encountered, things they are familiar with. Social psychologists refer to this tendency as the familiarity principle. Given a choice between two similar items, one they have experienced before and another that is new, most people will choose the familiar item. This principle operates even when people are not conscious of their previous experience with an item. Once people have been exposed to an item—even if they do not recall having been exposed to it—they will tend to prefer that item over other items to which they have not been previously exposed.
问题
Explain how the experiment described by the professor illustrates the familiarity principle.
