Abstract:  The perceivers categorize unfamiliar individuals based on gender, race and other social categories, in order to recognize and interact with others. Based on facial perception, a large number of studies have found that there are different interactions between different social subcategories. Using Who Said What Paradigm, Repetition Priming Paradigm, Garner Selective Attention Paradigm, Mouse-tracking Paradigm and other methods, researchers concluded that implicit processing of multiple subcategories is weakened by each other; and the interaction between explicit multiple categorization is asymmetrically or biased. The Theory of Dynamic Interaction and some other theories try to explain the causes of each interaction. Further work should differentiate the process stages of social subcategories scientifically and highlight the relationship and difference between implicit and explicit categorization. Meanwhile, it is necessary to integrate relative research paradigms to overcome the heterogeneity and contradictory resulting from method deviation in the future.

Key words: multiple social subcategories, interaction, facial perception, implicit processing, explicit processing
