Background. Word reading and linguistic comprehension skills are two crucial components in reading comprehension, according to the Simple View of Reading (SVR). Some researchers have posited that a third component should be involved in reading and understanding texts, namely executive function (EF) skills.Aim. This study was novel in two ways. Not only did we tested EF skills as a predictor of reading comprehension in a non-alphabetic language (i.e., Chinese) to extend the theoretical model of SVR, we also examined reading comprehension further in kindergarten children (age 5) in Hong Kong, in the attempt to reveal possible early precursors of reading comprehension.Sample(s). A group of 170 K3 kindergarteners was recruited in Hong Kong.Methods. Children’s word reading was assessed. Their linguistic comprehension was assessed with phonological awareness, verbal short-term memory, and vocabulary knowledge. Using a structured observation task, Head-Toes-Knees-Shoulders (HTKS), we measured their composite scores for EF skills.Results. Head-Toes-Knees-Shoulders performance predicted unique variance in children’s Chinese reading comprehension concurrently beyond word reading and a set of linguistic comprehension skills. Conclusions. The results highlight the important role of EF skills in beginning readers’ reading comprehension. Copyright © 2018 The British Psychological Society.

Current literature suggests mixed findings regarding the relationship between visual spatial skill and Chinese reading ability. In this longitudinal study, 106 kindergarteners in Hong Kong were tested on visual spatial skill and Chinese character reading ability in their first, second, and third years of kindergarten (K1, K2, and K3) with 12-month intervals between the three testing points. Cross-lagged path analysis showed a bidirectional relationship between visual spatial skill and Chinese character reading ability from K1 to K2. Children's visual spatial skill in K1 predicted their reading ability in K2 (B = 0.35, SE = 0.17, p < .05, β = .17), and their reading ability in K1 explained the unique variance of visual spatial skill measured in K2 (B = 0.29, SE = 0.12, p < .05, β = .25). In total, it explained 19.4% (p < .01) and 35.8% (p < .001) variance of visual spatial skill at T2 and reading ability at T2. However, the bidirectional relationship diminished between K2 and K3. The results demonstrate the developmental course of the relationship between visual spatial skill and reading ability as well as the reciprocal facilitation of the two skills in the beginning phase of reading development but not later phases.
