to be physically attractive came to behave in a more sociable, warm, and outgoing manner than targets whose partners believed them to be physically unattractive. Consequently, targets behaviorally confirmed the perceivers' beliefs, thus turning the perceivers' beliefs into self-fulfilling prophecies. The study also supported and displayed the physical attractiveness stereotype. These findings suggest that human beings, who are the targets of many perceivers in everyday life, may routinely act in ways which are consistent not with their own attitudes, beliefs, or feelings; but rather with the perceptions and stereotypes which others hold of them and their attributes. This seems to suggest that the power of others' beliefs over one's behaviour is extremely strong. Mechanisms Snyder proposed a four-step sequence in which behavioral confirmation occurs: the perceiver adopts beliefs about the target the perceiver acts as if these beliefs were true and treats the target accordingly the target assimilates his or her behavior to the perceivers overtures the perceiver interprets the targets behavior as confirmation of his or her original beliefs. Motivational foundations The perceiver and the target have a common goal of getting acquainted with one other, and they do so in different functions. Behavioral confirmation occurs from the combination of a perceiver who is acting in the service of the knowledge function and a target whose behaviors serve an adjustive function. The perceiver uses knowledge motivations in order to get a stable and predictable view of those whom one interacts, eliciting behavioral confirmation. Perceivers use knowledge-oriented strategies, which occur when perceivers view their interactions with targets as opportunities to find out about their targets' personality and to check their impressions of targets, leading perceivers to ask belief-confirming questions. The perceiver asks the target questions in order to form stable and predictable impressions of their partner, and perceivers tend to confidently assume that possession of even the limited information gathered about the other person gives them the ability to predict that that person's future will be consistent with the impressions gathered. When the target is motivated by adjustive functions, they are motivated to try to get along with their partners and to have a smooth and pleasant conversation with the perceiver. The adjustive function motivates the targets to reciprocate perceivers' overtures and thereby to behaviorally confirm perceivers' erroneous beliefs. Without the adjustive function, this may lead to behavioral disconfirmation. Examples Physical attractiveness – When one interacts with another person of
