Abstract Objective Executive functions such as working memory and cognitive flexibility are key to lifelong learning. Our hypothesis was that children born low birthweight (LBW), defined as weight < 2,500 g, would have lower cognitive outcomes than those born normal weight, and children with poor executive functioning would be at risk for poor academic outcomes. Study Design We evaluated data from 12,656 children followed prospectively in the Early Childhood Longitudinal Study, Kindergarten Class 2010–2011, assessing outcomes from kindergarten, first grade, and second grade. Multivariable linear and logistic regressions were run evaluating the relationship between birthweight and cognitive outcomes, and the odds of infants with poor executive functioning having poor academic outcomes. Results Compared with children with normal birthweight, those born LBW had lower mean z-scores for academic and directly assessed executive functions from kindergarten through second grade. LBW children were at an increased risk of scoring in the bottom 20% of children at all time points: second-grade reading odds ratio (OR) = 1.60 (95% confidence interval [CI:] 1.23–2.09), math OR = 1.49 (95% CI: 1.21–1.84), science OR = 1.41 (95% CI: 1.11–1.81), cognitive flexibility OR = 1.61 (95% CI: 1.27–2.02), and working memory OR = 1.40 (95% CI: 1.10–1.77). Conclusion LBW infants remain at risk of poor cognitive outcomes in second grade. Early difficulties with executive functioning can increase the risk of a child's academic performance years later.

Background:The current study investigates how children’s amount of daily physical activity relates to subcomponents of executive functions, the cognitive processes needed for goal-directed behavior. Previous studies rarely determined this association at the subcomponent level and did not explicitly examine the period when children make the transition to first grade, despite its importance for the development of executive functions.Methods:In a sample of 54 children, working memory, inhibition, and cognitive flexibility were thoroughly measured at the subcomponent level at the end of kindergarten and first grade. In the middle of first grade, children wore a pedometer for 7 consecutive days.Results:Regression analyses showed that performance on a measure of the visuospatial sketchpad, the central executive, and fluency was predicted by children’s amount of daily physical activity after controlling for initial task performance.Conclusions:The development of the visuospatial sketchpad (working memory), the central executive (working memory), and fluency (cognitive flexibility) might be improved by increasing the amount of time being physically active. However, as other subcomponents of executive functioning were not affected, the role of other aspects of physical activity, such as intensity and content, in the development of executive functions should be further investigated.

The Impact

PurposeProsociality is considered important in the study of offenders and associated cognitive skills: theory of mind, empathic understanding and moral reasoning, are said to enable self-control and reduce the risk of offending behaviours. Previous research has made associations between these skills and executive functioning; however, research into a link between them, in an offending population, is limited. The paper aims to discuss this issue.Design/methodology/approachTo further understand the practicalities of this, the present study considered the predictive abilities of the constructs believed to underpin executive functioning: working memory, cognitive flexibility and inhibitory control, in relation to theory of mind, empathic understanding and moral reasoning. In total, 200 male and female offenders completed measures in all six constructs.FindingsUsing path analysis working memory was demonstrated to be predictive of theory of mind and empathic understanding, cognitive flexibility was found to be predictive of theory of mind, and inhibitory control was found to be predictive of theory of mind, empathic understanding and moral reasoning.Research limitations/implicationsThe study focussed on offenders serving a custodial sentence of six months or less and did not differentiate between crime categories or take into consideration the socio-environmental backgrounds or ethnicity. Therefore, considering these things could further establish the generalisability of the current findings. It is noted that the more focussed the intervention is to the specific needs of an offender, the greater the impact will be. Therefore, pre-screening tests for the constructs discussed may be able to more accurately assess an offenders’ suitability for a programme, or indeed tailor it to meet the specific needs of that person.Practical implicationsThese findings may enable practitioners to more accurately assess offenders’ suitability for interventions aimed at reducing offending behaviours by improving levels of prosociality and develop more focussed programmes to meet the specific needs of individual offenders to reduce re-offending.Social implicationsAs recommended in the study, a more tailored approach to offender rehabilitation may be a potential aid to reducing levels of recidivism.Originality/valueThe present study adds to the literature as it is the first to consider whether the constructs of executive functioning can predict levels of theory of mind, empathic understanding and moral reasoning and so provide a more accurate method in assessing the cognitive abilities of offenders prior to participation in rehabilitative interventions.

IntroductionThe term executive functions (EFs) includes a set of cognitive processes such as planning, working memory, attention, problem solving, inhibition, mental flexibility, multi-tasking, and initiation and monitoring of actions. EFs are the higher order control processes to guide behaviour.Some studies on the relationship between EFs and autism spectrum disorder (ASD) showed deficit in the cognitive flexibility and speed processing, particularly with Asperger syndrome. Recently, Merchán-Naranjo et al. [1] supported that children's and adolescents with autism without intellectual disability are insufficient in at least 5 domains: attention, working memory, cognitive flexibility, inhibitory control and problem-solving.AimsOur work is aimed at verifying if the presence of a dysexecutive syndrome significantly impacts on the adaptive functioning of people with high functioning autism.MethodsA group of young adults with ASD were administered traditional neuropsychological assessment, specific assessment, focusing on the planning strategies for solving problems (Test Tower of London), abstraction and categorization (Wisconsin Card Sorting Test), and the Dysexecutive Questionnaires.ResultsThe results showed the presence of a specific deficit in the executive functioning in an average cognitive functioning.ConclusionsIntegrate the standard cognitive screening with a specific EFs assessment resulted to be very useful for the clinician to realize neuropsychological and psychotherapeutic individualized treatment.Disclosure of interestThe authors have not supplied their declaration of competing interest.

The Impact

The results of studies targeting cognitive and academic advantages in children frequenting early bilingual immersion school programs (CLIL) have been contradictory. While the impact of the amount of CLIL experience has already been studied, the role of the second language learned has been little studied to account for differences among study findings. The link between executive skills (EF) and scholar abilities (e.g., mathematics) in the CLIL context has also been little investigated. The purpose of the present study was to determine if the impact of CLIL on EF and academic performances varies depending on the immersion language and the duration of CLIL experience. The sample included a total of 230 French-speaking children attending second (141) and fifth (89) grade classes. Within each grade, there were three matched language groups composed of children respectively immersed in English, immersed in Dutch, and non-immersed controls. The children were administered tasks assessing executive functions [alerting, cognitive flexibility, and working memory], as well as arithmetic abilities. In second grade, we detected no difference in EF between the language groups. On the other hand, in fifth grade, the two immersed groups outperformed the non-immersed group on the cognitive flexibility task but did not differ between them. Moreover, only the Dutch immersed group outperformed the control group on the working memory task. Arithmetic performances also differed depending on the language learned; in second grade, Dutch learners performed better than the monolingual group. In fifth grade, Dutch learners outperformed the two other groups. These results suggest that the impact of CLIL on executive skills and arithmetic performances might be modulated by the amount of CLIL experience and the second language learned in immersion.

The relationship between executive functions (EF) and academic achievement is well-established, but leveraging this insight to improve educational outcomes remains elusive. Here, we propose a framework for relating the role of specific EF on specific precursor skills that support later academic learning. Specifically, we hypothesize that executive functions contribute to general math skills both directly – supporting the online execution of problem solving strategies – and indirectly – supporting the acquisition of precursor mathematical content. We test this hypothesis by examining the contribution of inhibitory control on processing rational numbers pairs which conflict with individual’s prior whole number knowledge and on general math knowledge. In 97 college students (79 female, age = 20.63 years), we collected three measures of EF: working memory (backwards spatial span), inhibition (color-word Stroop) and cognitive flexibility (task switching), and timed and untimed standardized measures of math achievement. Our target precursor skill was a decimals comparison task where correct responses were inconsistent with prior whole number knowledge (e.g. 0.27 vs. 0.9). Participants performed worse on these trials relative to the consistent decimals pairs (e.g. 0.2 vs. 0.87). Individual differences on incongruent Stroop trials predicted performance on inconsistent decimal comparisons, which in turn predicted performance on both timed and untimed measures of math achievement. With respect to relating inhibitory control to math achievement, incongruent Stroop performance was an independent predictor of untimed calculation skills after accounting for age, working memory and cognitive flexibility. Finally, we found that inconsistent decimals performance partially mediated the relationship between inhibition and untimed math achievement, consistent with the hypothesis that mathematical precursor skills can explain the relationships between executive functions and academic outcomes, making them promising targets for intervention.

A growing body of work has investigated the effects of acute, or single bouts of, aerobic exercise on cognitive function. However, review of this research has largely focused on changes following exercise, with less focus on cognitive changes during exercise. The purpose of this review is to discuss the critical characteristics of this literature to date, including: (1) what has been done, (2) what has been found, and (3) what is next. Furthermore, previous meta-analytic reviews have demonstrated there is a small positive effect on cognition when measured during exercise, with executive functions showing the largest effects. However, these reviews group executive functions together. Here we explore how inhibition, working memory and cognitive flexibility are individually impacted by factors such as exercise intensity or duration. Searches of electronic databases and reference lists from relevant studies resulted in 73 studies meeting inclusion criteria. Studies were grouped by executive and non-executive cognitive domains, intensity and duration of exercise bouts. Within the executive domain, we found that effects on working memory and cognitive flexibility remain mixed, effects on inhibition are clearer. Moderate intensity exercise improves response time, vigorous intensity impairs accuracy. Moderate to vigorous intensity improves response time across non-executive domains of attention, motor speed and information processing, with no significant effects on accuracy. Memory processes are consistently improved during exercise. Effects of exercise duration on response time and accuracy are nuanced and vary by cognitive domain. Studies typically explore durations of 45 min or less, extended exercise durations remain largely unexplored. We highlight factors to consider when assessing exercise-cognition relationships, as well as current gaps and future directions for work in this field.

Objectives: We investigated whether a school-based physical activity intervention would lead to improvements in working memory, inhibition and cognitive flexibility in adolescents aged 13–15 years. Methods: The adolescents at the active school ( n = 108) participated in an intervention that included increased physical activity for 20 min/day, focused on aerobic activity with low cognitive demands for an entire school year. The adolescents at the control school ( n = 59) received no extra physical activity. At the beginning (baseline) and end (follow-up) of the school year, the participants performed tests of executive function (working memory, inhibition and cognitive flexibility) and performed tests of physical fitness and health. Results: There was no change in executive functioning at follow-up when comparing the schools. However, only 46% complied with the intervention. When non-compliers were excluded from the analyses, the results remained the same, except for a small but significant increase in working memory for the active school as compared to the control school. Conclusion: These results indicate that compliance with the intervention was low and that aerobic exercise with low cognitive load does not produce improvements in executive functioning.

The Impact

Aim - The aim of this study is to measure the abilities of premature school-aged children in tasks of attention, working memory and executive functioning in order to determine if premature newborns are more at risk to develop delays compared to children born at term. Method - The sampling will be based on a previous study where five school-age premature children from Northern Ontario will be assessed using standardized tests. Each parent will be given a standardized questionnaire designed to measure the executive functioning of his or her child. The results will be then compared to those of a control group born at term without any neonatal complications. Participants will be matched according to gender, age, language status and socio-economic status. Preliminary analysis has shown that premature infants have reduced performance in tasks such as attention and executive functioning (inhibitory control, working memory, and cognitive flexibility). The influence of gestational age, birth weight and socio-economic status will be explained. Importance of the Study - Premature children are more vulnerable to developmental and behavioural delays (Taheri, Goudarzi, Shariat, Nariman, & Martin, 2017). Several studies have shown that delays in executive functions are associated with lower academic achievement (Hüning et al., 2017). This study will help us determine the nature of the impact on non-language skills in premature infants. Preliminary results will allow us to better understand the impact of prematurity on the development of attention and executive functioning (inhibitory control, working memory, and cognitive flexibility), as it relates to language.

Intraoperative Electrical Stimulation

Abstract BACKGROUND Over the past years, the functional subcortical architecture of the brain has been increasingly acknowledged in neurosurgical planning. A method to study anatomo-functional correlations is direct electrical stimulation (DES). DES is widely used by neurosurgeons and considered as a reliable tool to minimize the occurrence of permanent postoperative motor, language and visual deficits. In recent years, DES has also been used for mapping of other cognitive functions, such as executive functions. MATERIAL AND METHODS We systematically summarized the evidence so far from DES studies on subcortical pathways that are involved in the following three executive functions: (1) inhibitory control, (2) working memory and (3) cognitive flexibility. RESULTS We only found twelve articles that reported on intraoperative electrical stimulation of white matter pathways to map executive functions and explicitly clarified which subcortical tract was stimulated. The results indicate that the second branch of the right superior longitudinal fasciculus (SLF-II) is involved in inhibitory control, the first branch of the right superior longitudinal fasciculus (SLF-I) and the third branch of the left superior longitudinal fasciculus (SLF-III) are involved in working memory and the cingulum is involved in cognitive flexibility. CONCLUSION We were unable to draw any specific conclusions, nor unequivocally established the pathways involved in executive functions due to heterogenous study characteristics, methods and tasks, and the limited number of studies that assessed these relationships. Clearly, neurosurgical groups are exploring novel methods to assess cognition during awake neurosurgery, but are far from consensus on indications and protocols, which complicated the comparison and summarization of findings. We will discuss possible approaches for future research to obtain converging and more definite evidence for the involvement of subcortical pathways in specific executive functions.

The Relationship

The present paper is an empirical account of the relationship between conscious experience and executive functioning. Over the years, there has been a long debate but no common consensus on the functional aspect of consciousness has been arrived at. This may be due to lack of empirical studies in this direction. The present descriptive study on 200 adolescents examines the relationship between two executive functions (self-regulation and cognitive flexibility) and conscious experience, which were explored with the Consciousness Quotient inventory (CQI). The findings reveal a significant positive correlation between the consciousness quotient and the two executive functions. Through regression analysis, it has been shown that consciousness quotient is a predictor of both self-regulation and cognitive flexibility. Future prospects and educational implications in light of the results have been discussed.
