Abstract

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 (Mage 􏰀 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.

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 &

... Applying the MDM to ADHD and reading disability, the presence of genetic and environmental influences for each disability point to the presence of both genetic and environmentally linked deficits that contribute to the presence of these disabilities separately (Nikolas and Burt 2010;Zeeuw et al. 2015). The high comorbidity rates and past research showing overlap of the genetic and environmental influences between these two when ADHD or reading disability is present (Daucourt et al. 2020) gives further support to the idea that to some extent the same deficits that impact ADHD also impact reading disability, and vice versa. As such, the overlapping genetic and environmental influences represent the presence of domain-general deficits, whereas the genetic and environmental influences that are Edited by Valerie Knopik * Jeffrey A.

Despite this, findings of low correlations (phenotypic correlations and genetic correlations) between the full distributions of ADHD related behaviors and reading achievement have been found (Daucourt et al. 2020) calling into question of whether or not the MDM applies only in the lower ends of the distributions of these constructs, or if it applies throughout the distributions as a whole.

This paper extends the understanding of the relation between ADHD and reading comprehension, through examining how this relation differs depending on the quantile an individual falls in for each. Samples from three twin projects around the United States were used (Florida Twin Project, Colorado component of International Longitudinal Twin Study of Early Reading Development, & Western Reserve Reading and Math Projects). Phenotypic analysis using quantile regression showed relations between ADHD related behaviors and reading comprehension to be stronger in the lower quantiles of reading comprehension in two of three samples. A new method was developed extending this analysis into the bivariate genetic space. Results of this quantile genetic analysis revealed that overlapping common environmental influences accounted for a larger proportion of variance in the lower quantiles of these variables in two of three samples. Finally, in all three samples the phenotypic relation was strongest when shared environmental influences accounted for a larger proportion of the overall variance.

Purpose This study aims to examine the predictive relation between measures obtained from African American students' written narrative language samples and reading achievement, as measured by standardized academic assessments. Method Written language samples were elicited from 207 African American students in Grades 1–8. The samples were examined for morphosyntactic variations from standardized written Generalized American English (GAE). These variations were categorized as either (a) specific to African American English (AAE) or (b) neutral across AAE and standardized written GAE (i.e., considered ungrammatical both in AAE and in standardized written GAE). Structural equation modeling was employed to then examine the predictive relation between the density of AAE-specific forms in students' writing and their performance on standardized assessments of literacy and reading vocabulary. This relation was examined while accounting for the density of dialect-neutral morphosyntactic forms, reported family income, age, and written sample length. Results The written samples were highly variable in terms of morphosyntax. Younger students and those from lower income homes tended to use AAE-specific forms at higher rates. However, the density of AAE-specific forms did not significantly predict standardized literacy scores or reading vocabulary after accounting for dialect-neutral variations, income, and sample length. Conclusions These results support the ongoing need to better understand the language, literacy, and overall academic development of students from all backgrounds. It may be essential to focus on dialect-neutral language forms (i.e., morphosyntactic forms that are consistent across both AAE and standardized written GAE) in written samples to maximize assessment validity across students who speak varying dialects of English.

The goal of this chapter is to assess research that can inform understandings of places and spaces of learning.The chapter assesses evidence across three types of learning spaces: built spaces, digital spaces, and natural spaces. It looks at the role of these different kinds of spaces for learning, attainment, interpersonal relationships, skills development, wellbeing and behaviours ‒ across four pillars of learning to know, to be, to do and to live together. The chapter also explores how learning spaces can be actively shaped, felt and understood through practices and policies that occur within and around them.

This chapter assesses ways to identify and support children with learning disabilities. Learning disabilities affect many students and are seldom attributable to a single cause. They arise through complex interactions between biological and environmental factors within individual developmental trajectories. Early identification of children at risk for learning disabilities as well as adequate identification of children with learning disabilities are important for ensuring that children have access to the supports they need in order to reach their full potential. Here, we discuss identifying children’s learning needs and providing educational support. Although many school systems recognize the need to provide inclusive education to support all learners, more work is needed to raise awareness and enable adequate evidence-based early identification of children with learning disabilities and support their learning trajectories and instructional needs inside and outside of the classroom. It is also fundamental to acknowledge the importance of research on diverse populations that could inform identification and support in various countries and socio-cultural contexts.

ADHD, dyslexia, and dyscalculia often co-occur, and the underlying continuous traits are correlated (ADHD symptoms, reading, spelling, and math skills). This may be explained by trait-to-trait causal effects, shared genetic and environmental factors, or both. We studied a sample of ≤ 19,125 twin children and 2,150 siblings from the Netherlands Twin Register, assessed at ages 7 and 10. Children with a condition, compared to those without that condition, were 2.1 to 3.1 times more likely to have a second condition. Still, most children (77.3%) with ADHD, dyslexia, or dyscalculia had just one condition. Cross-lagged modeling suggested that reading causally influences spelling (β = 0.44). For all other trait combinations, cross-lagged modeling suggested that the trait correlations are attributable to genetic influences common to all traits, rather than causal influences. Thus, ADHD, dyslexia, and dyscalculia seem to co-occur because of correlated genetic risks, rather than causality.

Previous research has supported the use of latent variables as the gold-standard in measuring executive function. However, for logistical reasons genome-wide association studies (GWAS) of executive function have largely eschewed latent variables in favour of singular task measures. As low correlations have traditionally been found between individual executive function (EF) tests, it is unclear whether these GWAS have truly been measuring the same construct. In this study, we addressed this question by performing a factor analysis on summary statistics from eleven GWAS of EF taken from five studies, using GenomicSEM. Models demonstrated a bifactor structure consistent with previous research, with factors capturing common EF and working memory- specific variance. Furthermore, the GWAS performed on this model identified 20 new genomic risk loci for common EF and 4 for working memory reaching genome-wide significance beyond what was found in the constituent GWAS, together resulting in 29 newly mapped EF genes. These results help to clarify the underlying genetic structure of EF and support the idea that EF GWAS are capable of measuring genetic variance related to latent EF constructs even when not using factor scores. Furthermore, they demonstrate that GenomicSEM can combine GWAS with divergent and non-ideal measures of the same phenotype to improve statistical power.

ADHD, dyslexia and dyscalculia are comorbid. Also, the underlying continuous traits are correlated (ADHD symptoms, reading, spelling, and math skills). This may be explained by trait-to-trait causal effects and/or shared genetic and environmental factors. We studied a sample of ≤19,125 twin children and 2,150 siblings from the Netherlands Twin Register, assessed at ages 7 and 10. Children with a disorder, compared to those without that disorder, were 2.1 to 3.1 times more likely to have a second disorder. Still, most children with ADHD, dyslexia, and/or dyscalculia (77.3%) had just one disorder. Cross-lagged modelling suggested that reading causally influences spelling (β=.44). For all other trait combinations, cross-lagged modelling suggested that the trait correlations are due to genetic influences common to all traits, rather than causal influences. Thus, ADHD, dyslexia and dyscalculia seem to be comorbid due to correlated genetic risks, rather than causality.

However, for logistical reasons genome-wide association studies (GWAS) of executive function have largely eschewed factor scores in favour of singular task measures. As low correlations have traditionally been found between individual executive function (EF) tests, it is unclear whether these GWAS have truly been measuring the same construct. In this study, we addressed this question by performing a factor analysis on summary statistics from nine GWAS of EF taken from four studies, using GenomicSEM. Models were able to capture the classic three factors of inhibition, working memory, and set-shifting, although set-shifting and inhibition could be merged without negatively impacting model fit. Furthermore, the GWAS performed on a common factor model identified 63 new genomic risk loci beyond what was found in the constituent GWAS reaching genome-wide significance, resulting in 18 newly mapped EF genes. The majority of these have previous associations with brain morphology but no established associations with cognitive performance. These results help to clarify the underlying genetic structure of EF and support the idea that EF GWAS are capable of measuring genetic variance related to latent EF constructs even when not using factor scores. Furthermore, they demonstrate that GenomicSEM can combine GWAS with divergent and non-ideal measures of the same phenotype to improve statistical power.

This mini-review attempts to provide a capsule overview of the role of genetic factors in reading and its development across languages and writing systems. The review is conceived and executed with a scoping review approach, synthesizing the methods employed in the existing research rather than producing a summary of evidence to answer a discrete research question. Specifically, major research approaches in the field of quantitative- and molecular-genetic studies of (a)typical reading development are briefly reviewed and interpreted. Current frontiers of the field are described and places where evidence is insufficient to generate explicit statements about indisputable findings are highlighted. Overall, the resulting vector of the review points to the necessity of the relevant empirical work. Based on the available data at this point, it is impossible to comment authoritatively on the role of languages and writing systems as specifiers or modifiers of the genetic machinery underlying the development of reading skills, as a critical mass of relevant research does not currently exist. More relevant studies are needed to provide evidence-based conclusions about this role.

According to the Multiple Deficit Model, comorbidity results when the genetic and environmental risk factors that increase the liability for a disorder are domain-general. In order to explore the role of domain-general etiological risk factors in the co-occurrence of learning-related difficulties, the current meta-analysis compiled 38 studies of third through ninth-grade children to estimate the average genetic, shared environmental, and nonshared environmental correlations between reading and attention-deficit/hyperactivity disorder (ADHD) symptoms, and reading and math, as well as their potential moderators. Results revealed average genetic, shared and nonshared environmental correlations between reading and ADHD symptoms of .42, .64, and .20, and reading and math of .71, .90, and .56, suggesting that reading and math may have more domain-general risk factors than reading and ADHD symptoms. A number of significant sources of heterogeneity were also found and discussed. These results have important implications for both intervention and classification of learning disabilities.

A number of different approaches are currently used for assessing young children’s executive function (EF) and self-regulation (SR) skills. Nevertheless, guidance for stakeholders aiming to assess EF and SR in real-world settings (e.g., preschool classrooms) is currently lacking. In the present article, I review the properties, strengths, and weaknesses of three common approaches to EF and SR measurement: direct assessments, adult reports, and observational tools. Building on this general review, I next highlight several considerations specific to EF and SR measurement of young children in everyday contexts. In particular, I consider the ecological validity, interpretability, and scalability of each approach to EF and SR measurement, concluding with future directions for research.

Self-regulation describes the ability to control both behaviors and internal states against a backdrop of conflicting or distracting situations, drives, or impulses. In the cognitive psychology tradition, individual differences in self-regulation are commonly measured with performance-based tests of executive functioning, whereas in the personality psychology tradition, individual differences in self-regulation are typically assessed with report-based measures of impulse control, sustained motivation, and perseverance. The goal of this project was (a) to comprehensively examine the structure of associations between multiple self-regulatory constructs stemming from the cognitive and personality psychology traditions; (b) to estimate how these constructs, individually and collectively, related to mathematics and reading ability beyond psychometric measures of processing speed and fluid intelligence; and (c) to estimate the extent to which genetic and environmental factors mediated the observed associations. Data were available for 1,019 child participants from the Texas Twin Project ( M age = 10.79, range = 7.8–15.5). Results highlighted the differentiation among cognitive and personality aspects of self-regulation, both at observed and genetic levels. After accounting for processing speed and fluid intelligence, EF remained a significant predictor of reading and mathematics ability. Educationally relevant measures of personality—particularly an openness factor representing curiosity and intellectual self-concept—incrementally contributed to individual differences in reading ability. Collectively, measures of cognition, self-regulation, and other educationally relevant aspects of personality accounted for the entirety of genetic variance in mathematics and reading ability. The current findings point to the important independent role that each construct plays in academic settings.

Identifying the cognitive capacities associated with the development of school readiness is indispensable to support children’s successful school transition. It has been shown that executive function (EF) in preschoolers is associated with both concurrent preacademic and subsequent academic skills. However, most research has controlled for the effect of general cognitive ability (GCA), and little research has examined non-English speaking children, which hinders the understanding of the development of school readiness in culturally diverse contexts. In addition, behavioral genetic research on the genetic and environmental influences on this association has been conducted with school-age children. Thus, the genetic and environmental influences on associations between GCA, EF, and preacademic skills during preschool age are unknown. We conducted multivariate behavioral genetic analyses on two waves of longitudinal data at 42 and 60 months of age from 171 and 135 pairs of monozygotic and dizygotic Japanese twins. The findings suggested that a genetic factor influenced GCA at 42 months and mediated preacademic ability at 60 months. In addition, another genetic factor emerged by 60 months that genetically mediated EF and math ability, independent of GCA. Preacademic ability at 60 months was affected by shared environments that influenced EF, rather than GCA, at 42 months. Moreover, shared environments that influenced preacademic ability at 42 months affected later GCA at 60 months. Finally, nonshared environments that had emerged by 60 months mediated these relationships, though the magnitude of this effect was modest.

Self-control (SC) is an individual trait defined as the ability to pursue long-distance goals in spite of the obstacles generated by current desires, innate or learned automatisms, and physiological needs of an organism. This trait is relatively stable across the life span and it predicts such important features as level of income, quality of social relationships, and proneness to addictions. It is widely believed that the cognitive substrate of SC involves the executive functions (EFs), such as inhibitory control, shifting of attention, and working memory updating. However, the empirical evidence concerning the relationships between trait SC and EFs is not convincing. The present study aims to address two questions: (1) what is the strength of relationships between trait SC and EFs, and (2) which aspects of SC are predicted by particular EFs, if at all. In order to answer these questions, we carried out a psychometric study with 296 participants (133 men and 163 women, mean age 23.31, SD 3.64), whom we investigated with three types of tools: (1) a battery SC scales and inventories, (2) a battery of EFs tasks, and (3) two general intelligence tests. Structural equation modeling approach was used to analyze the data. We found that the latent variables representing SC and the latent variable representing EFs did not show any relationship. The standardized path coefficient between EFs and general intelligence turned out rather strong. We conclude that the trait of SC, measured with questionnaires, does not depend on the strength of cognitive control, measured with EFs tasks.

Recent achievement research suggests that executive function (EF), a set of regulatory processes that control both thought and action necessary for goal-directed behavior, is related to typical and atypical reading performance. This project examines the relation of EF, as measured by its components, Inhibition, Updating Working Memory, and Shifting, with a hybrid model of reading disability (RD). Our sample included 420 children who participated in a broader intervention project when they were in KG-third grade (age M = 6.63 years, SD = 1.04 years, range = 4.79–10.40 years). At the time their EF was assessed, using a parent-report Behavior Rating Inventory of Executive Function (BRIEF), they had a mean age of 13.21 years (SD = 1.54 years; range = 10.47–16.63 years). The hybrid model of RD was operationalized as a composite consisting of four symptoms, and set so that any child could have any one, any two, any three, any four, or none of the symptoms included in the hybrid model. The four symptoms include low word reading achievement, unexpected low word reading achievement, poorer reading comprehension compared to listening comprehension, and dual-discrepancy response-to-intervention, requiring both low achievement and low growth in word reading. The results of our multilevel ordinal logistic regression analyses showed a significant relation between all three components of EF (Inhibition, Updating Working Memory, and Shifting) and the hybrid model of RD, and that the strength of EF’s predictive power for RD classification was the highest when RD was modeled as having at least one or more symptoms. Importantly, the chances of being classified as having RD increased as EF performance worsened and decreased as EF performance improved. The question of whether any one EF component would emerge as a superior predictor was also examined and results showed that Inhibition, Updating Working Memory, and Shifting were equally valuable as predictors of the hybrid model of RD. In total, all EF components were significant and equally effective predictors of RD when RD was operationalized using the hybrid model.

Individual differences in cognitive paradigms are increasingly employed to relate cognition to brain structure, chemistry, and function. However, such efforts are often unfruitful, even with the most well established tasks. Here we offer an explanation for failures in the application of robust cognitive paradigms to the study of individual differences. Experimental effects become well established - and thus those tasks become popular - when between-subject variability is low. However, low between-subject variability causes low reliability for individual differences, destroying replicable correlations with other factors and potentially undermining published conclusions drawn from correlational relationships. Though these statistical issues have a long history in psychology, they are widely overlooked in cognitive psychology and neuroscience today. In three studies, we assessed test-retest reliability of seven classic tasks: Eriksen Flanker, Stroop, stop-signal, go/no-go, Posner cueing, Navon, and Spatial-Numerical Association of Response Code (SNARC). Reliabilities ranged from 0 to .82, being surprisingly low for most tasks given their common use. As we predicted, this emerged from low variance between individuals rather than high measurement variance. In other words, the very reason such tasks produce robust and easily replicable experimental effects - low between-participant variability - makes their use as correlational tools problematic. We demonstrate that taking such reliability estimates into account has the potential to qualitatively change theoretical conclusions. The implications of our findings are that well-established approaches in experimental psychology and neuropsychology may not directly translate to the study of individual differences in brain structure, chemistry, and function, and alternative metrics may be required.

The Florida State Twin Registry has existed for nearly two decades, and it grew primarily over 10 years as part of the Florida Learning Disability Research Center at Florida State University. The registry contains 2753 sets of twins and other multiples in Florida. The mean age of the sample currently is 17.96 years (SD = 2.05). The registry is diverse in terms of race and ethnicity (49% White, 19% African American, 24% Hispanic and 8% mixed or other). The characteristics of the samples and measures in the studies that served to build the registry are outlined.

Given that countless studies have documented the wide-ranging benefits of self-regulation, determining if and how self-regulation can be improved is an important scientific and societal priority. Existing theories suggest that the deterioration of self-regulation is partially shaped by perceptions of effort. Therefore, one promising way to sustain self-regulation may be to cultivate a growth mindset, which has been shown to affect behavior in part by altering effort attributions. Although growth mindsets-the belief that a given trait can be improved through practice-have been studied extensively, particularly in the domain of intelligence, little research has examined the effects of promoting a growth mindset specifically about self-regulation. Here five studies test how promoting a growth mindset of self-regulation impacts actual self-regulation in daily life and the laboratory. In Study 1, relative to an active control that received relationship training, an intensive self-regulation training program emphasizing a growth mindset led participants to persevere longer on impossible anagrams, which was partially mediated by altering attributions of mental fatigue. Relatively, the self-regulation training also led participants to notice more opportunities for self-control in daily life and more successfully resist everyday temptations. The subsequent four studies isolated and abbreviated the growth mindset manipulation, demonstrated improved persistence and decreased effort avoidance, and attempted to further examine the critical mediators. Collectively, results indicate that a growth mindset of self-regulation can change attributions and allocation of effort in meaningful ways that may affect the willingness to attempt challenging tasks and the perseverance required to complete them. Extensive research indicates that self-regulation-the ability to direct one's attention, thoughts, moods, and behavior in line with one's personal goals-is among the most critical skills in life. High levels of self-regulation predict better academic achievement, greater professional success and income, stronger interpersonal relationships, more fulfillment, and better health (. Given that self-regulation underlies such a diversity of highly valued outcomes, it would be of great value to identify successful interventions that can allow individuals to effectively develop and exert such control. An emerging consensus is forming that one powerful determinant of self-regulation is how an individual experiences and interprets effort
