PROJECT SUMMARY/ABSTRACT
In the United States, 67% of 4th graders are reading below proficiency, and this trend persists into adolescence
(8th grade). As such, the identification and remediation of reading-related difficulties remains critical. Although
many cases of poor reading comprehension result from poor decoding, or the ability to translate written words
into their spoken form, a substantial number of children struggle with comprehending text despite having
adequate decoding (i.e., specific reading comprehension deficit [SRCD]). SRCD affects 3-15% of children in the
general population, a prevalence rate that is similar to and/or exceeds other specific learning disabilities,
including dyslexia (3-15%) and dyscalculia (3-6%), which suggests that SRCD impacts a substantial number of
children and their families. Decades of research have investigated the origins, prevalence, and prognosis of
reading difficulties, but most have focused on the identification and remediation of poor decoding; comparatively
fewer studies have prioritized children with SRCD. Although increasingly more work is being done in this area,
several significant challenges are uniquely associated with SRCD, which continue to have downstream
implications for its identification and remediation and thus requires further study. First, children with SRCD have
average decoding and minimal phonological processing deficits. This is notable because deficits in these areas
are often cited as early indicators of later reading difficulties, and yet, they provide minimal information about
SRCD risk. Second, reading comprehension develops later than other reading-related skills, such as decoding.
This is a concern because not all reading difficulties are evident early, which suggests that SRCD has the
potential to persist well into adolescence, a period during which reading difficulties are notoriously difficult to
remediate. Third, how poor reading comprehension is often defined—reading comprehension lower than
(developmentally) expected—implies that weak reading comprehension relative to decoding occurs exclusively
at the low tail of the distribution. Although this approach ensures that we capture only those children who are
struggling with reading comprehension it ignores the fact that children with poor reading comprehension relative
to decoding exist along the entire distribution and may lead us to miss those whose poor reading comprehension
is unexpected. In the proposed project, I will address these limitations by moving away from the standard
discrepancy definition of SRCD to a more inclusive one and extending a novel approach that has been developed
and refined in simulation but has yet to be applied empirically. More specifically, the proposal aims to (1)
investigate the nature of specific reading comprehension deficit in large representative samples of childhood and
adolescent readers and (2) identify domain-specific, domain-general, and social skills-related correlates of
specific reading comprehension deficit. In this way, findings garnered from the proposed project can further
inform policy and practice aimed at supporting children whose ability to read text far outpaces their ability to
understand it.
