Abstract

The authors asked whether different forms of inhibition are altered differently by aging using a Motor and Perceptual Inhibition Test (MAPIT) based on Nassauer and Halperin (Nassauer & Halperin, 2003, Journal of the International Neuropsychological Society, 9, 25-30). Ninety-eight individuals participating in studies of balance and attention were separated into younger (mean age 25 years) and older (mean age 73) participants. Older participants showed less perceptual and motor inhibition than younger participants, with moderation of this effect by gender, that is, motor inhibition appeared to decline more sharply with age in women than in men. The two scores were uncorrelated in the young but significantly correlated in the older group. Overall, the MAPIT appeared to yield reliable measures of two aspects of inhibition that demonstrate a differential impact of age.
