The effect of exercise on cognitive performance in an older population was studied. Thirty sedentary men and women 65–72 years of age were randomly assigned to a walking group, a weight training group, or a placebo control group. Intervention groups exercised 30–60 min 5 days per week for 16 weeks, with the walking group training at 60% heart rate reserve, the weight training group employing the DAPRE method of weight progression, and the placebo control group engaging in mild range-of-motion and flexibility movements that kept their heart rates close to resting levels. At baseline and 16 weeks posttraining each subject completed the Ross Information Processing Assessment (RIPA), a maximal graded treadmill test, and a strength assessment of the knee extensors and elbow flexors. Sixteen weeks of walking improved VO2peak of the sedentary subjects 15.8%; VO2peak did not improve in the other two groups. Additionally, the RIPA scores of the walking group increased 7.5%, while those of the weight-training and control groups showed little change.

To increase data on the accuracy of students reporting their high school and college GPAs and SAT scores the sex and class differences of students who reported their grades and scores and those who did not were examined. Freshmen, sophomores, men, and women who reported their SAT scores had significantly higher SAT-M, SAT-V, and SAT-Total scores than those who did not. Differences between the actual scores of those reporting and those not reporting for the men were greater than those for the women. No consistent pattern was noted for the differences between the actual scores of those reporting and those not reporting for the freshmen and for the sophomores. No significant differences between the actual GPAs for men, women, freshmen, and sophomores reporting grades and those not reporting grades were noted for either high school GPAs or college GPAs.
