Metacognitive awareness of memory failure may take the form of the “blank in the mind” (BIM) experience. The BIM experience informs the person of a temporary memory failure and takes the form of a disruption in the flow of consciousness, of a moment of no content in awareness. The aim of the present study was to examine the psychometric properties of the Blank in the Mind Questionnaire (BIMQ) designed to tap the BIM experience and differentiate it from other memory-related experiences, such as searching but not having in memory a piece of information (i.e., lack of knowledge). The participants (N = 493) were 249 younger adults (18–30 years old) and 244 older adults (63–89 years old) of both genders. Confirmatory factor analysis applied to the BIMQ confirmed a three-factor model with interrelations between the factors. The first factor represented the experience of lack of knowledge, the second represented the experience of BIM, and the third the person’s negative affective reactions to memory failure. The internal consistency of the three factors ranged from Cronbach’s α = .80 to .88. Convergent validity was shown with correlations of the BIMQ factors with self-report measures of cognitive and memory failures, and to the negative-affect subscale of the Positive and Negative Affect Schedule (PANAS).
