“…Indeed, there is no reason to believe that elderly individuals are incapable of learning, even though many researchers nd that uid intelligence (e.g., reaction time and a general ability to solve abstract problems) decreases in old age (Baltes, 1993;Baltes & Staudinger, 1993;Glendenning, 1995;Moody, 1986;Shuldiner, 1992;Willis, 1985). But as longitudinal studies have shown, the potential for learning remains intact throughout the life time as long as cognitive functioning is not affected by neurophysiological diseases, such as Alzheimer's (Mason, 1974;O'Brien, 1992;Shuldiner, 1992;Thornton, 1986;Willis, 1985).…”
