“…To test for practice effects in this study, we used a novel upper extremity motor task that 1) has been used previously for studying motor learning in older adults (Schaefer, 2015; Schaefer, Dibble, & Duff, 2015; Schaefer & Duff, 2015; Schaefer, Patterson, & Lang, 2013); 2) has concurrent and ecological validity (Schaefer & Hengge, 2016); 3) is similar to other tasks yielding motor practice effects (Yan & Dick, 2006); and 4) is derived from standardized clinical assessments of hand function (Jebsen, Taylor, Trieschmann, Trotter, & Howard, 1969). …”
