Characteristics of vocabulary lists as well as study and test translation direction may affect the ease of learning second language (L2) vocabulary. We examined immediate and delayed test performance of first language (L1) English speakers learning a fixed set of L2 vocabulary placed on lists formed by crossing semantic relatedness (unrelated vs. related) with L2 orthographic form similarity (not similar vs. similar). During the study phase, half the participants translated from L2 to L1 and half from L1 to L2; tests were then taken in both directions. Semantic relatedness in the absence of form similarity improved accuracy when the first test taken translated from L2 to L1, and tended to hurt accuracy when the first test taken translated from L1 to L2; it sometimes increased confusion errors. Form similarity usually hurt accuracy and always increased confusion errors. The combination of the L1‐to‐L2 study direction with the optimal semantic and form conditions yielded the best long‐term performance.
There is a need to provide bilingual assessments and reference data to identify those who struggle to acquire their heritage language (L1) or the language spoken in the country of residence (L2). However, bilingual assessments and data are still sparse. Therefore, the aim was to use a tablet application to screen receptive vocabulary in different languages and discuss this data in the context of lexical acquisition theories. Forty-four monolingual German, 15 bilingual German-Polish and 21 German-Turkish-speaking children aged between 3;5 (3 years and 5 months) and 6;1 were assessed. All children completed the German version of the Receptive Vocabulary Screener (RVS), a tablet application testing 20 nouns and 20 verbs, and two standardized vocabulary subtests. Additionally, the bilingual children completed the Turkish or Polish version of the RVS. Internal consistency showed that the RVS is a reliable tool for research purposes and validity was confirmed by significant and moderate to strong correlations with the two standardized vocabulary sub-tests. Monolingual children outperformed bilingual children when performance comparisons were solely based on the German items. However, group differences were not
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
