According to the hybrid model (van Bergen, van der Leij, & de Jong, 2014), the significant association
among executive functioning (EF), reading, and math may be partially explained by parent-reported EF’s
role as a common risk and/or protective factor in reading and math (dis)abilities. The current study used
a sample of 434 twin pairs (M
age
⫽12.12) from Florida to conduct genetically sensitive modeling on
children’s parent-reported EF, reading, and math skills to determine the common and unique etiological
influences among the three domains. EF was measured through parent report and reading and math were
measured with standardized test scores drawn from Florida’s Progress Monitoring and Reporting
Network as well as standardized parent-administered assessments collected by mail. Our trivariate
Cholesky modeling showed that no matter which parent-reported EF component was modeled, the
overlap of parent-reported EF with reading and math was explained by common genetic influences.
Supplemental analysis suggested that this might in part be due to general parent report of problem
behaviors. Additionally, significant environmental influences, with higher shared environmental overlap
than previous work, were also found for reading and math. Findings indicate that poor parent-reported
EF is a common cognitive risk factor for reading and math disabilities, which is driven by a shared
genetic basis among all three domains.

During a single class, schoolchildren are expected to sit in their
seats and not speak out of turn, while following multistep instruc-
tions, alternating attention between different assignments, and
integrating new and previously learned information on demand
(Gathercole, Lamont, & Alloway, 2006). The coordination of such
complex demands requires a high degree of self-regulatory ability
in order to adapt one’s thoughts and actions to respond to current
contextual needs. The mechanism that drives goal-directed self-
regulation, like controlling one’s behavioral impulses based on
classroom rules or focusing one’s attention to listen to a teacher’s
lesson, is hypothesized to be the brain’s central executive, or
executive functioning (EF; Baddeley, 1998). Specifically, EF rep-
resents the processing efficiency of an individual’s cognitive con-
trol system (Stanovich, 2009;Toplak, West, & Stanovich, 2013),
which is driven by prefrontal cortex functioning (Welsh & Pen-
nington, 1988;Welsh, Pennington, & Groisser, 1991), and proffers
individuals with the ability to adapt their cognitive processes and
behaviors to their present goals (Toplak et al., 2013).
In terms of academic achievement, EF has been shown to have
significant associations with both reading (Daucourt, Schatsch-
neider, Connor, Al Otaiba, & Hart, 2018) and math (Clark,
Pritchard, & Woodward, 2010), which may be attributable to EF’s
role as a common cognitive risk and protective factor among
learning (dis)abilities. In support of the principle of common
underlying causes among learning disabilities, previous work on
reading and math has shown that students already experiencing an
academic skill deficit in one domain are four to five times more
likely to experience a deficit in an additional academic domain
compared to typically developing students (Landerl & Moll,
2010). On the other hand, high EF skills may help children do
well in both the reading and math domains (Ten Eycke &
