Math and verbal fluency across adulthood provide insights into aging and individual differences (opens in new tab)

Life expectancy is increasing, leading to a growing population of older adults. Although cognitive functions decline with age, mathematical functioning in later adulthood has received relatively limited research attention. The present study examined age-related changes in mathematical fluency across all four basic arithmetic operations (addition, subtraction, multiplication, division) to determine whether aging affects these operations uniformly or whether specific operations show greater vul...
