Abstract
The study aims to examine whether mothers of two different cultural groups living together in South Tyrol, Italian (I, N = 69) and German (G, N = 69), differ with respect to knowledge of infant developmental milestones. A second purpose of the present work is to understand if possible differences on maternal knowledge could account for diverse levels of mastery on adaptive behaviours. Results show that mothers of the two cultural and linguistic groups did not differ on knowledge of infant milestones, while significant differences emerge in the development of daily living skills and socialization between Italian and German children ( G > I).
