Theory of mind and inhibitory control in three cultures: Conflict inhibition predicts false belief understanding in Germany, Costa Rica and Cameroon

Abstract

This study investigates the relationship of theory of mind and inhibitory control in three samples from Europe, Africa and Latin America differing in relevant socioeconomic and psychological background. The relationship between false belief understanding and inhibitory control was tested using samples of 3 to 5 year-old preschoolers from Germany (N = 116), Costa Rica (N = 82) and Cameroon (N = 116). Inhibitory control and theory of mind were examined using test batteries. Age, gender, siblings, language understanding and mother's education were controlled. Results of regression analyses controlling for moderating effects of culture show a culture-independent relation between conflict inhibition and false belief understanding while delay inhibition is not a significant predictor for false belief understanding across cultures. Conflict inhibition is discussed as a universal developmental prerequisite for the development of theory of mind in the preschool years.
