The article presents a cross-cultural analysis of those ethnocultural features of the emotion concept of SHAME in Ukrainian, Anglo-Saxon and German linguo-cultures, which directly correlate with some national characteristics of the representatives of these linguo-cultures. It deals with the role of shame in the generation of such a social phenomenon as infantilism, since the significant spread of this phenomenon in a particular linguo-society is the basis for determining infantilism as one of the features of the national character. A comparative study of the representative corpora data of Ukrainian, English and German has revealed that Ukrainians, although a European linguo-society, belong not to guilt culture, as the Anglo-Saxons and Germans, but to shame culture, because this emotion arises in them mostly in in-groups, transforming into shame, humiliation, pangs of conscience, but not guilt. This feature of Ukrainians’ psychological type brings them closer to Eastern cultures, correlating to the greatest extent with such a criterion of cultures distinctions as collectivism–individualism. The low rate of individualism in the Ukrainian linguo-society has led to the fact that Ukrainians tend to be less responsible for their actions than Anglo-Saxons or Germans, often shifting their responsibility to external factors. The unwillingness of a large number of individuals to take responsibility indicates a certain immaturity of the society as a whole. This gives grounds to claim that the concept СОРОМ is one of the markers of social infantilism of the Ukrainian people.
