The aim of the present study was to show effects drawing direction (top-down vs. bottom-up) and angle trace participant drew (0 60 300) on stability varying length (5.7 cm 11.4 17.1 cm) for elderly. These three independent variables were within-subject factors. Thirty-eight older adults (18 females, 20 males; mean age = 71.7, SD 5.5) participated in study. task performed a computer with touch s...
