Which term defines the increase in attractiveness due to repeated exposure to a person?

The term that defines the increase in attractiveness due to repeated exposure to a person is the mere exposure effect. This psychological phenomenon suggests that individuals tend to develop a preference for things merely because they are familiar with them. Repeated exposure to a person can lead to increased comfort and a more positive evaluation of that individual, making them appear more appealing over time. This effect is supported by various studies in psychology, indicating that initial neutral or even negative feelings can shift to a more positive disposition with ongoing exposure.

In contrast, the attrition effect typically refers to the loss of participants in a study, which does not relate to attractiveness. Social preference indicates a general favoring of certain individuals or groups, which does not specifically address the impact of repeated exposure. The familiarity advantage suggests that familiarity can lead to a preference, but it is not as widely recognized or defined as the mere exposure effect in psychological literature. Thus, the mere exposure effect is the most accurate term for this phenomenon.
