Age stereotypes: Dimensions, origins, and consequences

We give an overview of what age stereotypes (AS) are, how they are acquired and change across the lifespan, and how they shape development in old age. AS reflect complex beliefs and expectations that vary on the following dimensions: They differ in content and valence, depending on the life-domain to which they are applied (context), they refer to different age-groups (reference), to older people or to oneself as an old person (direction of relevance), and they either describe how older people are or prescribe how they should be (modality). AS are acquired early, and later taint beliefs about one's own aging (internalization). Once they are part of the self-concept, AS act as self-fulfilling prophecies that shape the actual aging process (stereotype embodiment).
