Measurement: Aging and the Psychology of Self-Report

The cognitive changes associated with normal human aging can profoundly affect the processes underlying self-reports of opinions and behaviors, giving rise to age-sensitive context effects. As a result, any observed age difference in self-reported attitudes and behaviors can reflect (a) a true difference, (b) a difference in the response process, or (c) an unknown mixture of both. In this paper the author illustrates the problem by highlighting three age-sensitive context effects that are sufficiently pronounced to thwart meaningful cohort comparisons: question order effects, response order effects, and the effects of alternative responses.
