Eighty-seven mothers and their four-year-old children from Eastern Turkey (N = 32 pairs), Western Turkey (N = 30 pairs) and the USA (N = 25 pairs) participated in a study of mother-child memory talk as a reflection of mothers' self construal, in view of differences in the function of memory talk across cultures. Mother-child pairs were audio-recorded while talking about shared past and anticipated future events. Mothers completed the Balanced Integration-Differentiation questionnaire measure of self-construal and were scored as high or low on individuation and relatedness orientations. Mothers' memory and future talk showed similar patterns of cultural differences: American mothers provided the most voluminous, descriptive and elaborative talk, while Eastern Turkish mothers showed the highest level of repetitiveness, and Western Turkish mothers' talk fell in between. Children's memory talk was similar across cultures. In all cultures, mothers who scored high on both individuation and relatedness (balanced self-construal subtype) engaged in more voluminous and contexted memory talk, and individuation was associated with more elaborative talk about future events. Results are discussed in light of literature on cultural differences in self-construal and memory function.
