[Measurement of the feeling of knowing: norms of 216 general-information questions].

The purpose of this study is to provide the normalized list of questions for investigating the feeling of knowing. Normative data were collected on 216 general-information questions from a wide variety of topics, including history, sports, art, literature, and so on. Three hundred and sixty-three undergraduates made a one-word response to each question, or rated their feeling of knowing on a 7-point scale if they could not recall any responses. The results showed that the questions distributed over a wide range on a scale of difficulty. There were few incorrect responses to the questions. Feeling-of-knowing ratings were moderately correlated with the probabilities of correct answers. These findings suggested that the questions provided in this study would serve for the research on the feeling of knowing. It was also suggested that the use of easier questions should generate a strong feeling of knowing.
