Subjective well-being (SWB) is linked to better cognitive performance in Brazilian older adults. Life satisfaction, a key component of SWB, positively correlates with cognitive function, suggesting it may indicate successful aging.
Area of Science:
- Positive psychology
- Gerontology
- Cognitive neuroscience
Background:
- Subjective well-being (SWB) is crucial for health and cognitive reserve in aging.
- Limited Brazilian research exists on SWB's impact on cognitive domains.
Purpose of the Study:
- To investigate the relationship between SWB and cognitive performance.
- Focus on cognitively healthy older adults in Brazil.
Main Methods:
- Longitudinal study with 183 older adults (mean age 67.3).
- Assessed SWB using life satisfaction and affect scales.
- Measured cognitive function with ACE-R and MMSE.
Main Results:
- High SWB and cognitive performance observed in the sample.
- General life satisfaction correlated positively with MMSE and ACE-R attention/orientation.
- Satisfaction with mental capacity linked to global cognitive performance.
Conclusions:
- Healthy, educated older adults show high SWB and cognitive function.
- Reinforces SWB's association with cognitive reserve.
- Suggests SWB as a marker for successful aging.
