Maternal reminiscing styles and mother–child memory features were examined in a cross-cultural context. Fifty-five Chinese (Guangzhou, China) and 48 Australian (Melbourne, Australia) mother–child dyads (child age: 3–6 years) independently retrieved autobiographical memories and jointly discussed past events. Australian mothers used greater elaborative and supportive reminiscing and provided more specific memories than Chinese mothers. Australian children provided greater memory elaboration than Chinese children, but they did not differ in memory specificity. Maternal reminiscing styles and cultural group were independently predictive of child memory elaboration but not specificity. Nonetheless, moderation analyses showed that the two maternal reminiscing styles (elaborative and supportive) interacted to predict child memory specificity. These findings indicate the importance of culture and types of reminiscing on memory development.
