Curious people tend to have more of the experiences linked to cognitive reserve, study finds

A recent Dutch study suggests that individuals with a more curious personality tend to have higher indicators of cognitive reserve, such as education and engaging in mentally stimulating activities, but this does not necessarily correlate with better cognitive test performance. The research, published in Personality and Individual Differences, aimed to explore the relationship between curiosity and cognitive reserve, which refers to the brain's ability to maintain cognitive function despite aging or disease.

The study involved 106 adults aged 40 to 85 living in the Netherlands, excluding those with psychiatric or neurological disorders. Participants completed questionnaires assessing their curious personality and the Dutch version of the Cognitive Reserve Index, which estimates cognitive reserve based on education, work complexity, and leisure activities.

They also underwent brief neuropsychological tests measuring memory, executive function, and processing speed. The findings indicate that more curious individuals generally scored higher on cognitive reserve indicators, particularly education and leisure activities, but not work complexity, after accounting for age. However, curiosity itself and the cognitive reserve indicators did not correlate with cognitive test results.

The authors note that the study's cross-sectional design and relatively healthy, high-IQ sample limit its ability to establish causality. Nonetheless, the results support the idea that curiosity may drive individuals toward cognitively enriching experiences, even if those experiences do not directly enhance cognitive abilities.
