This longitudinal study examined the performance of poor comprehenders on several reading-related abilities in the late elementary school years. We identified 3 groups of readers in Grade 5 who were matched on word reading accuracy and speed, nonverbal cognitive ability, and age: unexpected poor comprehenders, expected average comprehenders, and…

Considers how the reading-level match design has become a widely-used tool for investigating the possible direction of the relation between particular skills and word reading ability: cause or consequence. Outlines an analogous method for identifying candidate causes of reading comprehension failure, the "comprehension-age match design."…

Investigates the direction of young children's reading comprehension skill in association with their ability to draw inferences and explores possible sources of inferential failure. Finds that the ability to make inferences was not a by-product of good reading comprehension, rather that good inference skills are a plausible cause of good reading…

Presents six experiments that investigate the hypothesis that text comprehension problems in young children arise from phonological processing difficulties for children in the presence of age-appropriate word reading skills. Supports previous work which indicates that poor comprehenders' problems arise from higher-level processing difficulties.…
