A recent study published in Clinical Psychological Science suggests that a person’s mastery of language, specifically verbal fluency, may be a significant predictor of longevity. Conducted by Paulo Ghisletta from the University of Geneva, the research analysed data from the Berlin Aging Study, which followed 516 individuals aged 70 to 105 over a span of up to 18 years.
The study aimed to explore the relationship between various cognitive abilities and longevity, focusing on verbal fluency alongside other cognitive traits such as perceptual speed, verbal knowledge, and episodic memory. Participants underwent a series of cognitive tests, including one that assessed verbal fluency by requiring them to name as many animals as possible within a 90-second timeframe.
Key findings revealed that verbal fluency emerged as the most significant cognitive predictor of survival among the elderly. While the exact reasons for this connection remain unclear, one leading theory suggests that cognitive, emotional, and physical health are interconnected, and that verbal fluency may reflect overall well-being.
Ghisletta noted that understanding the links between cognitive abilities and longevity is vital, as it can inform strategies for promoting healthy aging. He emphasised the importance of collaborative research efforts and the availability of rich longitudinal data, which allow for comprehensive analyses of aging-related factors.

This study contributes to the growing body of evidence that intelligence and cognitive functioning are critical components in understanding longevity, highlighting the potential benefits of fostering language skills throughout life.
