This paper examines age-based stereotypes in accordance with the Stereotype Content Model in four different age groups: schoolchildren, adolescents, adults and the elderly. Participants were asked to rank graphic portraits of both genders of four age clusters in terms of warmth and competence. The hypothesis that age groups, besides a positive evaluation of their own age cluster, would rate old people in an increasingly negative way as they themselves get older, was not confirmed. On the contrary, young children seem to have the most extreme prejudice against older people. Interestingly, adults and elderly appear to evaluate their own age cluster rather negatively too. Other relations between age groups indicate that ageism does not only affect old people and that it can include positive stereotypes as well. It is also argued, that ageism may have a changing pattern throughout the lifespan.
