Disentangling Stereotypes towards Older Age Groups: Evidence from Factorial Survey Experiments in China and the USA.

Introduction: Older adults are usually perceived as warmer but less competent than younger adults. This study examined how these stereotypes are related to domain-specific attributes and how individuals' values may moderate the association.

Methods: We recruited 560 Chinese participants (mean age [SD]: 23.14 ± 7.08 years old, ranging from 18 to 60 years old) and 479 American participants (mean age [SD]: 31.37 ± 7.19 years old, ranging from 18 to 57 years old). Participants rated perceived warmth and competence of older adults based on vignettes with varying descriptions of specific domains (i.e., three relational domains: number of friends, family relationship quality, and engagement in neighbourhood activities; and three individualistic domains: income, depression, and memory) and personal attributes (i.e., gender, age, and independence).

Results: Firstly, the results showed that relational domains predict warmth, whereas individualistic domains predict competence in both samples from China and the USA. Secondly, in both samples, people with higher communal values attributed more relevance to relational domains on judgement of warmth. Lastly, only in the US sample did people with higher agentic values attribute more relevance to individualistic domains on judgement of competence.

Discussion/conclusion: The study revealed that personal values, when determined relatively, contribute to stereotypes of older adults in the two independent samples.
