Abstract

Development of Cognitive and Academic Abilities in Greek Elementary School Students The development of language and reading skills is closely linked to the maturation ofcognitive abilities. This study focuses on Attention and Executive skills (EFs) and theirconnection with the development of language and reading skills among elementary schoolstudents, with emphasis on reading comprehension. In the context of two studies weexamined: the effect of Attention and EFs on Reading Comprehension controlling for printrelatedskills, the direct and indirect effects of attention, the factors that may moderate theseeffects of cognitive abilities on Reading Comprehension, and the cognitive and academicperformance of children demonstrating teacher-rated ADHD-related symptoms. A battery of tests assessing Sustained Attention, Short-term Memory (STM), EFs, andacademic skills was administered to a representative sample of, largely untreated, Greekelementary school students (N= 597 and N=923, respectively). Attention and EFs contributedsignificant additional variance to the prediction of Reading Comprehension after controllingfor efficiency, accuracy, morphosyntactic and vocabulary knowledge. Attention-relatedabilities contributed to Reading Comprehension indirectly through EFs. The only factor thatmoderated the effects of EFs on Reading Comprehension was Reading Efficiency. Significantdeficits in EFs and STM were restricted to the groups of students displaying inattentionsymptoms. Results demonstrated a close link between EFs, other than inhibition and set-shifting,everyday symptoms of inattention, and achievement in math and word-level reading skills.Reduced performance on EF measures was identified as the most important factor thatdistinguished between students with pervasive academic difficulties and their typicallyachieving peers, regardless of the presence of inattention symptoms. Considering the crosssectionalnature of the present study, our results provide some support to the hypothesis that EF deficits are causally related to developmental academic difficulties, and may set a firmbasis for implementing a cognitive approach to the management of students with ReadingComprehension difficulties and severe inattention symptoms.
