Abstract Objective To explore different effects of emotional and ethnic information on the cognitive and metacognitive processes of face pictures during the encoding and extraction stages. Methods A 2 （emotional information: positive, negative） × 2 （ethnic information: own-race, other-race） within-subjects design was used to record subjects’ learning time, recognition scores, judgement of learning, and judgement of confidence. Repeated measurement analysis of variance and simple effects analysis were performed. Results Study time was influenced by emotional information only, with shorter study time for negative emotional faces. The other-race effect emerged for recognition performance, which was moderated by emotional information. Judgement of learning was influenced by ethnic information and moderated by emotional information. The trend for judgement of confidence was the same as that for recognition scores. Conclusion For the cognitive processing of face pictures, only emotional information influences the cognitive processing during the encoding stage. Ethnic information significantly influences the cognitive processing during the extraction stage, and emotional information plays a moderated role. For the metacognitive processing of face pictures, emotional and ethnic information have a joint effect in both the encoding and extraction stages.
