Measuring executive function skills in young children in Kenya

Interest in measuring executive function skills in young children in low- and middle-income country contexts has been stymied by the lack of assessments that are both easy to deploy and scalable. This study reports on an initial effort to develop a tablet-based battery of executive function tasks, which were designed and extensively studied in the United States, for use in Kenya. Participants were 193 children, aged 3–6 years old, who attended early childhood development and education centers. The rates of individual task completion were high (65–100%), and 85% of children completed three or more tasks. Assessors indicated that 90% of all task administrations were of acceptable quality. An executive function composite score was approximately normally distributed, despite higher-than-expected floor and ceiling effects on inhibitory control tasks. Children’s simple reaction time (β = –0.20, p = .004), attention-related behaviors during testing (β = 0.24, p = .0005), and age (β = –0.24, p = .0009) were all uniquely related to performance on the executive function composite. Results are discussed as they inform efforts to develop valid and reliable measures of executive function skills among young children in developing country contexts.     

Teaching directional skills to preschool and kindergarten children

Studied a new device and training procedure for teaching the directional orientation and sentence tracking skills used in reading and writing western languages. Twelve preschool and 14 kindergarten children were randomly assigned to E and C groups. Between pre- and posttests, Es practiced for a total of 20 min. over a two-week period with an electronic device which flashed a correct signal only when S scribed left-to-right through successive sentences from top to bottom of the display. Any error in sequence extinguished the signal. Cs received only pre- and posttests. On test sentences prior to practice neither Es nor Cs were able to show where the sentences began or how they went from beginning to end. After using the device, Es tripled their orientation and tracking scores, while Cs not given access to the device did not improve (p < .002). Left-right and up-down directional confusion, often the subject of many hours of remedial training, were shown to be rapidly corrected in normal children by the use of a simple electronic device providing clear feedback distinguishing correct from incorrect responses. Implications for prereading instruction are discussed.     

Measuring executive function skills in young children in Kenya: Associations with school readiness

Most of what is known about the association between children’s executive function (EF) and school readiness skills is derived from research conducted in Western countries. We tested whether these associations were evident in a middle‐income country context. Participants were 1,480 children, aged 4–7 years old, who participated in an endline assessment of the Tayari program, an early childhood education (ECE) model that is being delivered by the Kenyan education system. High rates of task completion, low rates of floor effects, and high rates of assessor quality ratings supported the feasibility of large‐scale direct assessments of EF with young children. Assessor ratings of children’s attention‐related behaviors during testing were positively associated with their performance on EF tasks (rs = 0.12–0.27). An EF composite score was not related to demographic factors or to children’s exposure to the Tayari program. However, the EF composite score was uniquely associated with performance‐based measures of early literacy (β = 0.18, 95% confidence interval [CI] = 0.05, 0.31), early numeracy (β = 0.16, 95% CI = 0.07, 26), and social‐emotional competencies (β = 0.12, 95% CI = 0.03, 0.20), even after adjustment for multiple covariates. These results are discussed with respect to the ways in which EF skills inform ongoing efforts to invest in ECE in low‐ and middle‐income countries.     

Cognitive and behavioral rating measures of executive function as predictors of academic outcomes in children

Interrelations of two measurement methods (cognitive versus behavioral ratings) for executive function (EF) were examined and related to reading comprehension and math calculations in fourth and fifth grade students (n = 93) in the context of a diverse urban student population. Relations among measures within four EF processes (working memory, planning, inhibition and shifting) were modest; relations to academics were stronger. EF measures contributed to both academic outcomes even in the context of relevant covariates (age, language and educational program). Working memory was particularly important for reading comprehension across measurement type. Cognitive measures from all EF processes, particularly inhibition and planning, and behavioral ratings of working memory were important for math.     

Adaptive skills and executive function in autism spectrum disorders.

There is active debate regarding the nature of executive dysfunction in autism. Additionally, investigations have yet to show a relationship between deficits in executive function and the everyday behavioral difficulties that may originate from them. The present study examined the relationship between executive abilities and adaptive behavior in 35 children with Autism Spectrum Disorders, using two parent reports of everyday functioning, the Vineland Adaptive Behavior Scales (VABS) and the Behavior Rating Inventory of Executive Function (BRIEF). Results found several relationships: The Initiate and Working Memory domains were negatively correlated with most domains of adaptive behavior. Also, the Communication and Socialization domains of the VABS were negatively correlated with several areas of executive functioning, suggesting that impairments in executive abilities are strongly associated with the deficits in communication, play and social relationships found in children with autism.     

Parenting,corpus callosum,and executive function in preschool children

In this longitudinal population-based study (N?=?544), we investigated whether early parenting and corpus callosum length predict child executive function abilities at 4 years of age. The length of the corpus callosum in infancy was measured using postnatal cranial ultrasounds at 6 weeks of age. At 3 years, two aspects of parenting were observed: maternal sensitivity during a teaching task and maternal discipline style during a discipline task. Parents rated executive function problems at 4 years of age in five domains of inhibition, shifting, emotional control, working memory, and planning/organizing, using the Behavior Rating Inventory of Executive Function-Preschool Version. Maternal sensitivity predicted less executive function problems at preschool age. A significant interaction was found between corpus callosum length in infancy and maternal use of positive discipline to determine child inhibition problems: The association between a relatively shorter corpus callosum in infancy and child inhibition problems was reduced in children who experienced more positive discipline. Our results point to the buffering potential of positive parenting for children with biological vulnerability.     

Universality and context-specificity in early executive function development

A renewed interest in early executive function (i.e., EF or the conscious control of thought and behavior) development has led several research groups to suggest that EF may be emerging and is less coordinated (e.g., showing few relations between tasks) in the first few years (Devine et al., 2019; Gago Galvagno et al., 2021; Johansson et al., 2016; Miller & Marcovitch, 2015; Ribner et al., 2022). This potentially universal development in EF does not exclude the possibility that EF may also differ across context (e.g., Gago Galvagno et al., 2021; Lohndorf et al., 2019; Tran et al., 2015) reflecting unique strengths and development built within one’s sociocultural environment. The present paper explores potential universal and context-specific early EF developments by focusing on three aims: (1) reviewing work on EF within the first two years of life that may speak to potential universality in the measurement, structure, growth, stability, and conceptualization of early EF (2) reviewing research that may speak to how the sociocultural context may play a role in context-specific development within early EF and (3) examining potential developmental EF frameworks for understanding universal and context-specific developments of early EF within context.     

Relationships among perceptual-motor, self-concept, and academic measures for children in kindergarten, grades one and two.

Most studies reporting correlations of psychomotor and cognitive measures deal with perceptual-training programs for the remediation of academic deficiencies. This study provided additional information about the relationships of perceptual-motor ability and academic achievement for children in kindergarten through the second grade, and included self-concept. A small positive relationship between perceptual-motor ability and academic ability was observed for all three grade levels. There was little indication of any significant relationship between self-concept and academic ability, which provides no basis for the hypothesis proposing self-concept as an intervening variable in the relationship between the perceptual-motor and academic areas, at least for such young subjects.     

Assessment of executive function in preschool-aged children

Assessment of the overarching self-regulatory mechanisms, or executive functions, in any age group is challenging, in part due to the complexity of this domain, in part due to their dynamic essence, and in part due to the inextricable links between these central processes and the associated domain-specific processes, such as language, motor function, and attention, over which they preside. While much progress has been made in clinical assessment approaches for measuring executive functions in adults and to some extent in adolescents and school-aged children, the toolkit for the preschool evaluator remains sparse. The past decade, however, has seen a substantial increase in attention to executive functions in very young children from a developmental neuropsychological perspective. With this has come a necessity for better, more specific, and more internally valid performance measures, many of which are now described in the experimental literature. Few such tasks, however, have adequately demonstrated psychometric properties for clinical application. We present two performance tasks designed to tap selective aspects of executive function in preschoolers that are emerging from the experimental laboratory and hold promise of appropriate reliability and validity for the clinical laboratory. Performance tests alone, however, are insufficient to develop a comprehensive picture of a child's executive functioning. Thus, we present a rating scale of preschoolers' executive function in the everyday context, and advocate a model of executive function assessment that incorporates both controlled performance tasks that target specific aspects of executive function and parent/teacher ratings that target more global aspects of self-regulation in the everyday context.     

Modeling relationships between physical fitness,executive functioning,and academic achievement in primary school children

ObjectivesThe relationship between physical fitness and academic achievement in children has received much attention, however, whether executive functioning plays a mediating role in this relationship is unclear. The aim of this study therefore was to investigate the relationships between physical fitness, executive functioning, and academic achievement, more specifically to test whether the relationship between physical fitness and academic achievement is direct or indirect, via executive functioning.DesignCross-sectional.MethodThis study examined 263 children (145 boys, 118 girls), aged 7–12 years, who performed tests on physical fitness, executive functioning, and academic achievement.ResultsIn a structural equation model linking physical fitness to executive functioning and academic achievement there was a significant relationship between physical fitness and executive functioning (r = .43, R² = .19) and academic achievement (r = .33, R² = .11). Adding a relationship from executive functioning to academic achievement resulted in a non-significant direct link between physical fitness and academic achievement (r = −.08, R² = .006). However, a significant indirect relation through executive functioning persisted. The indirect relation between fitness and academic achievement (r = .41), was stronger than both the direct and total relation (r = .33).ConclusionExecutive functioning thus served as a mediator in the relation between physical fitness and academic achievement. This highlights the importance of including executive functioning when studying the relationship between physical fitness and academic achievement in children.     

Neuropsychological executive functioning in children at elevated risk for alcoholism: findings in early adolescence

One component of individual risk for alcoholism may involve cognitive vulnerabilities prodromal to alcoholism onset. This prospective study of 198 boys followed between 3 and 14 years of age evaluated neurocognitive functioning across three groups who varied in familial risk for future alcoholism. Measures of intelligence, reward-response, and a battery of neuropsychological executive and cognitive inhibitory measures were used. Executive functioning weaknesses were greater in families with alcoholism but no antisocial comorbidity. IQ and reward-response weaknesses were associated with familial antisocial alcoholism. Executive function effects were clearest for response inhibition, response speed, and symbol-digit modalities. Results suggest that executive deficits are not part of the highest risk, antisocial pathway to alcoholism but that some executive function weaknesses may contribute to a secondary risk pathway.     

Common mechanisms of executive attention underlie executive function and effortful control in children

Executive Function (EF) and Effortful Control (EC) have traditionally been viewed as distinct constructs related to cognition and temperament during development. More recently, EF and EC have been implicated in top‐down self‐regulation ‐ the goal‐directed control of cognition, emotion, and behavior. We propose that executive attention, a limited‐capacity attentional resource subserving goal‐directed cognition and behavior, is the common cognitive mechanism underlying the self‐regulatory capacities captured by EF and EC. We addressed three related questions: (a) Do behavioral ratings of EF and EC represent the same self‐regulation construct? (b) Is this self‐regulation construct explained by a common executive attention factor as measured by performance on cognitive tasks? and (c) Does the executive attention factor explain additional variance in attention deficit hyperactivity disorder (ADHD) problems to behavioral ratings of self‐regulation? Measures of performance on complex span, general intelligence, and response inhibition tasks were obtained from 136 preadolescent children (M = 11 years, 10 months, SD = 8 months), along with self‐ and parent‐reported EC, and parent‐reported EF, and ADHD problems. Results from structural equation modeling demonstrated that behavioral ratings of EF and EC measured the same self‐regulation construct. Cognitive tasks measured a common executive attention factor that significantly explained 30% of the variance in behavioral ratings of self‐regulation. Executive attention failed to significantly explain additional variance in ADHD problems beyond that explained by behavioral ratings of self‐regulation. These findings raise questions about the utility of task‐based cognitive measures in research and clinical assessment of self‐regulation and psychopathology in developmental samples.     

Classroom problem behavior and teacher-child relationships in kindergarten: The moderating role of classroom climate

Young children with problem behavior in the classroom are at risk for developing more conflictual and less close relationships with their teachers. Two studies in kindergarten (N = 3798; N = 237) shed light on some aspects of classroom climate that can moderate this risk for relational problems. Results showed problematic classroom compositions, in terms of high average levels of internalizing or externalizing behavior, to exacerbate the risk for teachers to form more conflictual relationships with children showing externalizing behavior. Additionally, observed emotional support of teachers was found to be protective for the relational functioning of children at risk due to maladjusted behavior. Specifically, with emotionally supportive teachers, children who expose internalizing or externalizing behavior are no longer at risk for developing less close or more conflictual relationships with their teachers respectively. Practical implications and limitations of the studies are reported and suggestions are made for future research.     

Verbal and nonverbal predictors of executive function in early childhood

The study of executive function (EF) has become increasingly popular in multiple areas of research. A wealth of evidence has supported the value of EF in shaping notable outcomes across typical and atypical development; however, little evidence has supported the cognitive contributors to early EF development. The current study used data from a large longitudinal sample of healthy children to investigate the differential influence of verbal and nonverbal cognition on later EF. Participants were assessed at 2 years of age using the Mullen Scales of Early Learning, and Mullen scores were used to calculate nonverbal and verbal developmental quotients. Executive function was measured at 6 years using assessments from the Stanford-Binet, Cambridge Neuropsychological Test Automated Battery, and the Behavior Rating Inventory of Executive Function. Results suggested that early nonverbal cognition was a better predictor of 6-year EF as measured by task-based laboratory assessments, whereas verbal cognition was a better predictor of parent-reported EF. Findings are discussed in regard to EF development and characteristics of EF measurement.     

Being proven wrong elicits learning in children – but only in those with higher executive function skills

This study investigated whether prompting children to generate predictions about an outcome facilitates activation of prior knowledge and improves belief revision. 51 children aged 9–12 were tested on two experimental tasks in which generating a prediction was compared to closely matched control conditions, as well as on a test of executive functions (EF). In Experiment 1, we showed that children exhibited a pupillary surprise response to events that they had predicted incorrectly, hypothesized to reflect the transient release of noradrenaline in response to cognitive conflict. However, children's surprise response was not associated with better belief revision, in contrast to a previous study involving adults. Experiment 2 revealed that, while generating predictions helped children activate their prior knowledge, only those with better inhibitory control skills learned from incorrectly predicted outcomes. Together, these results suggest that good inhibitory control skills are needed for learning through cognitive conflict. Thus, generating predictions benefits learning – but only among children with sufficient EF capacities to harness surprise for revising their beliefs.     

Psychological correlates of peer victimisation in preschool: social cognitive skills,executive function and attachment profiles

Most research into peer victimisation has focussed on children aged 8 years and above and has included a study of the correlates of victimisation, including cognitive and social skills, and attachment profiles. Recent research has started to investigate aggression and victimisation in younger groups and has found that the nature of aggression differs from that in older children in terms of the types of victimisation involved and the stability of the roles. This study investigated some of the correlates of roles taken in victimisation in 104 children aged 4–6 years, using a cartoon methodology to elicit peer nominations for aggressor, victim, and defender. It examined the social cognitive abilities, executive function skills, and attachment profiles of aggressors, victims, and defenders. Victims did not exhibit poor performance on the social cognitive tasks or have insecure attachment qualities as has been found with victims during middle childhood. Aggressors did not perform highly on the social cognitive tasks in contrast to older aggressors and bullies. Defenders were found to perform above average (although not significantly different from other groups) on the social cognitive tasks. These findings are related to the nature of aggression and victimisation at this age, and a developmental change hypothesis is proposed to accommodate them. Aggr.
