摘要： Age-related differences in affective meanings of words are widely used by researchers studying emotions, word recognition, attention, memory and text -based sentiment analysis. However, no Chinese affective norms for older adults are available. This article firstly presents the available large-scale Chinese affective norms for 2, 061 4-character words rated in labs by 114 older and 150 younger adults (CAN4Age) who evaluated these words on four dimensions: valence, arousal, dominance, and familiarity. We also compiled 4 lexical variables for each word, including word frequency, word complexity, character frequency and character complexity. In general, older adults tend to evaluate emotional words more extremely than younger adults do. That is, they rate positive words as more positive and negative words as more negative than younger adults do. Specifically, older adults tend to perceive positive words as more arousing and less controllable and negative words as less arousing and more controllable than that of younger adults. This age-related database will enable researchers to study how emotional characteristics of words influence their cognitive processing, and how this influence evolves with age in Chinese. This age-related difference study on affective norms not only provides insights to cognitive neuroscience, gerontology and psychology in experimental studies, but the produced affective word collection also has great value as a resource for affective analysis in natural language processing applications. These norms can be downloaded as supplemental materials with this published article.
