Listening comprehension and word decoding are the two major determinants of the development of reading comprehension. The relative importance of different language skills for the development of listening and reading comprehension remains unclear. In this 5-year longitudinal study, starting at age 7.5 years (n = 198), it was found that the shared variance between vocabulary, grammar, verbal working memory, and inference skills was a powerful longitudinal predictor of variations in both listening and reading comprehension. In line with the simple view of reading, listening comprehension, and word decoding, together with their interaction and curvilinear effects, explains almost all (96%) variation in early reading comprehension skills. Additionally, listening comprehension was a predictor of both the early and later growth of reading comprehension skills.The ability to read text with understanding is one of the core aims of primary school education, and adequate reading comprehension skills are essential for educational success and adult well-being. It is well established that the development of reading comprehension depends critically on word decoding and listening comprehension (the simple view of reading; Hoover & Gough, 1990;Gough & Tunmer, 1986). However, many questions remain about the relative importance of different oral language skills (e.g., vocabulary, grammatical, and inferential skills) as influences on the development of listening and reading comprehension. There is also a lack of consensus about the exact form of the relationships between word reading and listening comprehension as determinants of reading comprehension. Here we answer these critical questions using data from a large-scale longitudinal study.
The Simple View of ReadingThere are several different models that have been used as frameworks for understanding how reading comprehension develops (Cromley & Azevedo, 2007;Kintsch, 1988;McNamara & Kintsch, 1996;Perfetti & Stafura, 2014). However, for elementary school children, by far the most commonly cited theoretical framework is the simple view of reading (Gough & Tunmer, 1986). In this view, understanding written text is the product of decoding and listening comprehension. Decoding refers to the ability to convert print into sound and to read fluently (see NICHD Early Child Care Research Network, 2005). The simple view implies that when decoding skills are poor, they will place important constraints on reading comprehension. In contrast, when decoding skills are stronger, listening comprehension becomes a more important influence on reading comprehension. In the last 30 years, the simple view of reading has been used in a number of studies across different languages, particularly in studies of children in early elementary school but also in some studies of later elementary school children (see Garc ıa & Cain, 2014 for a meta-analysis).The basic tenets of the simple view of reading are supported by a large body of evidence. According to a recent meta-analysis (Garc ıa & Cain, 2014), there ...
