Self-Reported Cognitive Failures in Everyday Life: A Closer Look at Their Relation to Personality and Cognitive Performance.

A recent review concluded that the Cognitive Failures Questionnaire is the most widely used instrument to assess cognitive failures. Our aims were to place cognitive failures self-reported with the Cognitive Failures Questionnaire into their nomological network by conceptually replicating known relations to the Big Five and by extending this knowledge through testing their relations with latent cognitive abilities (Study 1, N = 158, age 20-86 years) and theoretically relevant Big Five subfacets (Study 2, N = 176, age 19-39 years). Cognitive failures were unrelated to objective cognitive performance (processing speed, memory, and inhibition), but reliably related to the personality domains conscientiousness, neuroticism, and almost all their subfacets. Thus, self-reported cognitive failures do not qualify as a proxy for objective cognitive performance tasks. They are rather useful as illustration of behavioral manifestations related to personality domains.
