Abstract
Sleep-related attentional bias is considered to play a key role in the development and maintenance of chronic insomnia disorders. The purpose of this study was to develop the lists of sleep-related words and neutral words for use in a cognitive task to assess attentional bias. In Study 1, twenty-four lists (24 sleep-related words and 120 neutral words) were extracted using the “Association Frequency Table” and the “Balanced Corpus of Contemporary Written Japanese”. In Study 2, the survey (n = 300) regarding the extent to which these words are related to sleep was conducted. The results showed significant impression rating differences between sleep-related words and neutral words in all lists. It is expected that these lists will be used as a reference for developing a cognitive task to evaluate attentional bias toward sleep-related stimuli in the future.
