A researcher at the University of Dallas hypothesized that engaging in new and challenging cognitive activities would improve outcomes on the Montreal Cognitive Assessment (MoCA), which is a test of cognitive functioning. One hundered and two (102) older adults (ages 65 to 75) were selected at random and divided, at random, into a treatment group and a control group; there were 51 individuals in each group. The treatment group participated in a computer programming course for 3 hours a day for four weeks. The control group spent 3 hours a day watching television in the common room of a local seniors' home. At the end of the four-week period, all 102 individuals were administered the MoCA. The results of the experiment were as follows: mTreatment - 28.972, mcontrol - 25.327, STreatment - 2.881, and Scontrol = 3.414.
