Answer:
According to Snyder, Tanke and Berscheid (1977), this effect is a type of self-fulfilling stereotype.
Explanation:
Snyder, Tanke and Berscheid studied the social nature of stereotypes and how, although we might think that stereotypes are grounded in real characteristics, they are in fact produced and reproduced in interaction. They found that people tend to treat others in a way that responds to the stereotype they have of the others, for example, if attractive females are considered to be warm and friendly, when a person interacts with a female that he considers attractive, he will treat her in a way that the female responds warm and friendly, thus confirming the stereotype. Their findings have had implications in the study of cultural stereotypes related to racist conducts.
