Verbal Fluency Selectively Predicts Survival in Old and Very Old Age Open
Intelligence is known to predict survival, but it remains unclear whether cognitive abilities differ in their relationship to survival in old age. We analyzed longitudinal data of 516 healthy adults (age: M = 84.92 years, SD = 8.66 years a…
