RESUMO

In the present study, the development of semantic categorization and its relationship with reading was investigated across Dutch primary grade students. Three Exemplar-level tasks (Experiment 1) and two Superordinate-level tasks (Experiment 2) with different types of distracters (phonological, semantic and perceptual) were administered to assess semantic categorization skills. Reading was measured with a standardized word-reading test. Results of both experiments demonstrated that children in the higher grades had shorter reaction times and fewer errors than children in the lower grades. Reading skill, however, was not related to semantic categorization performance. Moreover, neither grade level nor reading skill was related to the effect of distracter type on error percentages. Based on the results of this study, we suggest a substantial development of semantic categorization skills over time, and reject the notion that Dutch poor readers have less advanced semantic categorization skills than typical readers.

RESUMO

UNLABELLED: Learning to read is a major obstacle for children who are deaf. The otherwise significant role of phonology is often limited as a result of hearing loss. However, semantic knowledge may facilitate reading comprehension. One important aspect of semantic knowledge concerns semantic categorization. In the present study, the quality of the semantic categorization of both deaf and hearing children was examined for written words and pictures at two categorization levels. The deaf children performed better at the picture condition compared to the written word condition, while the hearing children performed similarly at pictures and written words. The hearing children outperformed the deaf children, in particular for written words. In addition, the results of the deaf children for the written words correlated to their sign vocabulary and sign language comprehension. The increase in semantic categorization was limited across elementary school grade levels. LEARNING OUTCOMES: Readers will be able to: (1) understand several semantic categorization differences between groups of deaf and hearing children; (2) describe factors that may affect the development of semantic categorization, in particular the relationship between sign language skills and semantic categorization for deaf children.
