Are personality questionnaires answered mindlessly?

Abstract

Langer (1978) suggests that repetitive tasks may induce more automatic or mindless responding. Since many personality questionnaires consist of large numbers of questions of a similar form, a possible implication is that such questionnaires are sometimes completed mindlessly. To test this implication, a questionnaire was presented to 150 subjects which contained (both early and late in the questionnaire) items from the Dominance and Impulsivity subscales of Jackson's (1974) Personality Research Form. These items were separated by, or randomly interspersed with, filler items that were either similar (other subscales of the Personality Research Form) or dissimilar (attitude statements concerning nuclear energy). Item order was counterbalanced. It was hypothesized that the inclusion of dissimilar filler items should inhibit mindless responding to the later items. Change scores comparing late and early items showed a significant effect of the type of filler on the Impulsivity scores. A similar trend on the Dominance subscale was not significant. It is argued that personality research should pay more attention to the nature of the cognitive processes involved in self‐rating measures.
