Expectations about memory change across the life span are impacted by aging stereotypes

Area of Science:

• Psychology
• Cognitive Aging
• Social Psychology

Background:

• Age-related memory decline is a common societal belief.
• Personality traits are known to influence social perceptions.
• The interplay between personality, age, and memory expectations requires further investigation.

Purpose of the Study:

• To investigate how personality traits affect age-based expectations of memory functioning.
• To determine if the valence and relevance of personality traits moderate these expectations.
• To examine age differences in the influence of personality on memory beliefs.

Main Methods:

• Selected 11 adjective clusters varying in valence and memory relevance from established age-stereotype trait sets.
• Recruited 373 participants across three age groups.
• Participants rated the memory abilities of hypothetical target adults described by these adjective clusters across the adult lifespan.

Main Results:

• Confirmed the general belief in age-related memory decline.
• Positive personality traits were associated with higher perceived memory ability and less decline compared to negative traits.
• The impact of personality traits on memory expectations was amplified when traits were relevant to memory functioning, with older participants showing a greater susceptibility to these effects.

Conclusions:

• Personality characteristics significantly shape perceptions of memory across the adult lifespan.
• The valence and relevance of traits critically influence memory expectations, particularly in older adults.
• These findings highlight the complex interaction between social cognition, personality, and beliefs about aging and memory.
