Previous research has shown a relation between culture and mental state reading in the form of the cultural in-group effect, which is defined as the advantage in reading mental states from the own cultural group compared with other groups. Thus, orientation toward cultures can be assessed not only in self-reported behavioral and psychological acculturation but also in the domain of social¨Ccognitive abilities. The aim of the current research is to gain insight into acculturation in the social¨Ccognitive ability of mental state reading. In addition, it explores how this facet of acculturation is related to the more traditionally studied behavioral and psychological acculturation. Cross-cultural mental state reading, language and possession of friends (behavioral acculturation), and cultural identification (psychological acculturation) were assessed in Antillean Dutch (n = 128), Moroccan Dutch (n = 204), and Dutch (n = 349) young adults between 19 and 24 years old (M = 21.57 years, SD = 1.38 years). For cross-cultural mental state reading, the in-group effect was confirmed for the Dutch but not for the Antillean Dutch and Moroccan Dutch participants. Furthermore, there were no consistent associations between mental state reading and behavioral and psychological acculturation in the three groups. The present results extend fundamental research on cross-cultural mental state reading and also help to further understand the orientation of these specific cultural groups %K acculturation %K cross-cultural mental state reading %K bicultural %U https://journals.sagepub.com/doi/full/10.1177/0022022118823283
