Aging Is Not All Doom And Gloom: How Do Beliefs About Aging Moderate The Effects Of Mortality Salience On Ageism Attitudes?, Kristen Schwindt Edmondson

Masters Theses & Specialist Projects

The purpose of the study is to examine how young adults’ beliefs about aging moderate the effects of mortality salience on their ageism attitudes. Past research suggests that ageism is, in part, due to the presence of elderly people reminding people of their own aging process and mortality (Martens et al., 2004). Little is known, however, about how individuals’ beliefs about aging may moderate the impact of mortality salience on their attitudes toward aging. Some people tend to perceive aging-related changes as relatively fixed (i.e., essentialist belief), whereas others perceive them as relatively malleable (nonessentialist belief). Would a more malleable …
