| Growth mindset of aging (MA) refers to the belief that the aging process is malleable, while fixed MA refers to the belief that the aging process is non-malleable. Using experimental methods, this thesis aimed to explore the novel impact that MA has on implicit old-age attitudes, self-perceptions of aging (SPA), age identity, and working memory. 86 older participants (Mage= 66.72 years) were randomly placed into either a growth or fixed MA condition and tested on the outcomes of interest. Analyses revealed that although the two groups significantly differed on MA scores following the manipulation, MA did notsignificantly influence any of the outcomes of interest. However, havingmore of a growth MA was related to less negative implicit old-age attitudes and more positive SPA. These results demonstrate that having more of a growth MA relates to beneficial psychological outcomes, and should be promoted in older populations.Keywords: mindset of aging, implicit attitudes, self-perceptions of aging, age identity, working memory, older adults |
