The Cognitive Failures Questionnaire (CFQ) is a self-report inventory of cognitive slippage in the form of failures in everyday actions, perceptions and attention, and memory.[1] It was developed by Donald Broadbent and others in 1982 at the University of Oxford's Department of Experimental Psychology.[2][3] The authors originally intended for the questionnaire to measure three distinct factors: perception, memory, and motor function. Subsequent analysis has found four distinct factors measured, which partially overlap with the intended factors.[4]
