پیش بینی های شناختی موفقیت در یادگیری زبان روسی در زبان بومی و غیر زبان مادری در دوره دبیرستان

The study focused on the role of the speed of information processing, working memory and non-verbal intelligence in the success in learning Russian assessed with teacher ratings (annual grades) and state exam scores in native and non-native speakers at high school age. Russian-speaking students, who study in different educational environments, differed in non-verbal intelligence, but not the speed of information processing and working memory. Russian-speaking students, who study in Kyrgyzstan, showed better performance at the Russian language exam, than their Kyrgyz-speaking peers. Non-verbal intelligence predicted success in learning Russian across all groups.
