Language development of twins provides a possibility to study the environmental effects on language acquisition. This study focuses on the recognition of nonsense words in a repetition task, discrimination of speech sounds, and sentence and text comprehension. Nearly 400 Hungarian-speaking young children (aged between 5 and 9) participated in the experiments. We compared the correct performance (repetitions, discriminations, answers to comprehension questions) between groups of twins and non-twins. Results indicate that singletons performed better than twins in serial perception and text comprehension while no differences could be found between them in speech sound discrimination and sentence comprehension tests. Findings showed a slight linear development across ages both in twins and non-twins.
