Training cognitive functioning in the elderly--inability to replicate previous findings

This study was designed to replicate Hornblum and Overton's study which trained conservation ability in elderly women [1]. Thirty-four elderly women volunteers were given a pretest battery of area and volume conservation tasks; participants also completed an extensive life history questionnaire. Conservation scores were the highest yet recorded by elderly participants. Thirty-two women received perfect conservation scores; only two were "partial conservers"; no participant was a "nonconserver." Consequently, training was not implemented. These women had high levels of education, good health, adequate income, satisfying leisure activities, and positive attitudes about aging. Advanced chronological age does not guarantee poor conservation performance. The mechanism(s) whereby life history variables influence cognitive functioning needs to be determined.
