Objective: The purpose of this study was to investigate the effect of integrity conceptual processing on blackness and whiteness perception, and to provide data support for the bidirectional problem of conceptual metaphor. Methods: A single factor 3-level design was adopted in the experiment, and 40 college students were selected as experimental subjects. The word types were taken as independent variables, divided into honest words, dishonest words and neutral words, and the percentage of words judged by the subjects to be bright over the color block was taken as dependent variable. Results: The main effect of word type was significant, and there was significant difference in the percentage of bright words in color block. Conclusion: There is a metaphor-based reverse interference effect and an obvious metaphorical congruence effect in the perception of blackness and whiteness. The subjects tend to judge the honest words as brighter and the dishonest words as darker.
