Developing psycholinguistic norms for action pictures in Cantonese.

The purpose of this study was to establish psycholinguistic norms for 249 action pictures in Cantonese, a language with few norms available. We provide normative data for rated visual complexity, rated age of acquisition, name agreement, word frequency and rated familiarity in this study. Forty participants were recruited to participate in both timed picture naming and rating experiments. The linear mixed effect analysis revealed that familiarity, visual complexity, and name agreement were significant predictors of action naming in Cantonese. However, AoA did not show any significant effect on action naming, which is consistently observed in previous studies of action picture naming in Chinese. The possible explanation for null effect of AoA on naming latency are discussed. This set of psycholinguistic norms in Cantonese could serve as a valuable resource for future psycholinguistic, neurolinguistic and clinical studies in Cantonese.
