The relation between language proficiency and executive functions has been established for monolingual children. The present study addresses this issue in bilingual children, comparing the language proficiency of sequential English–Hebrew bilingual preschool children as determined by standardized assessment instruments and generic executive control in inhibition, sorting and shifting tasks. Participants were recruited from regular and language preschools and classified according to their language proficiency as bilinguals with high language proficiency in at least one of their languages (including balanced bilinguals with high language proficiency in both languages, L2-dominant, and L1-dominant) and bilinguals showing low language proficiency in both languages. As reported for monolingual preschool children, positive relationships between language proficiency and inhibition and shifting abilities were found, with significantly lower performance among low language proficiency bilinguals. Significantly better performance was also found for shifting among children who had already mastered their L2 compared to those who were still in the process of acquiring the new language.

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 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.

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.

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.

Objective: This study examined effects of transcranial direct current stimulation (tDCS) over the dorsolateral prefrontal cortex (DLPFC) and orbitofrontal cortex (OFC) on major executive functions (EFs), including response inhibition, executive control, working memory (WM), and cognitive flexibility/task switching in ADHD. Method: ADHD children received (a) left anodal/right cathodal DLPFC tDCS and (b) sham stimulation in Experiment 1 and (a) left anodal DLPFC/right cathodal OFC tDCS, (b) left cathodal DLPFC/right anodal OFC tDCS, and (c) sham stimulation in Experiment 2. The current intensity was 1 mA for 15 min with a 72-hr interval between sessions. Participants underwent Go/No-Go task, N-back test, Wisconsin Card Sorting Test (WCST), and Stroop task after each tDCS condition. Results: Anodal left DLPFC tDCS most clearly affected executive control functions (e.g., WM, interference inhibition), while cathodal left DLPFC tDCS improved inhibitory control. Cognitive flexibility/task switching benefited from combined DLPFC-OFC, but not DLPFC stimulation alone. Conclusion: Task-specific stimulation protocols can improve EFs in ADHD.

AbstractListening effort seems to depend on input-related listening demands and several factors internal to the individual listener. Input-related demands may be listening in noise compared with listening in quiet, and internal factors may be cognitive functions.The purpose was to apply measures of listening effort and perceived listening effort in participants with normal hearing, to determine if there are any presentation order effects, and to explore the relationship between listening effort measured as accuracy, response times, efficiency of information encoding into long-term memory, perceived listening effort, and core executive functions.A within-subject design with repeated measures was used and a study of relationships between variables was made.Thirty-two healthy adults with normal hearing.Participants were tested individually by a listening task using a dual-task paradigm. The listening task was performed in quiet and in multitalker babble noise at 10 dB signal-to-noise ratio (SNR). Perceived listening effort and core executive functions (working memory, inhibitory control, and cognitive flexibility) were also assessed.The measures of listening effort (correct responses, response times, and immediate and delayed listening comprehension) failed to demonstrate increased listening effort in multitalker babble noise (10 dB SNR) compared with quiet, although a significant test order effect was seen for correct responses indicating that participants who first listened in noise did not improve in quiet. Perceived listening effort increased significantly in noise compared with quiet. No relationship was found between measures of listening effort and ratings of perceived listening effort. Working memory and cognitive flexibility were not related to ratings of perceived listening effort. In contrast, better inhibitory control was related to higher ratings in both quiet and in noise.It is possible that the SNR and measures used were not as sensitive as required to measure listening effort behaviorally. In the present experimental setup, prior noise exposure impedes the beneficial effects of performing a task in quiet. Self-reports seem to provide a valid measure of perceived listening effort that is related to the individual’s inhibitory control. The present findings suggest that participants with better inhibitory control are more susceptible to the task demand level both in quiet and in noise.

Abstract Objectives: The study’s aim was threefold: examine 1) the relation between executive functions and coach-rated evaluation of game intelligence; 2) the predictive value of cognitive and athletic performance parameters concerning playing time, and 3) injuries to analyze fundamental associations of soccer expertise across all ages.Design/Methods: A sample of 172 elite soccer players (12-34 years of age) performed tests assessing multiple-object tracking, working memory capacity, cognitive flexibility, and inhibition. Endurance-performance at the individual anaerobic threshold (IAT), ability to repeatedly perform intense exercises (RIEA) and maximal anaerobic performance parameters (squat jump, countermovement jump, drop jump, sprint) were also measured. Game intelligence game time and injury incidence were tracked.Results: Working memory capacity, cognitive flexibility, and a total cognition score showed correlations with game intelligence, and the same parameter, along with selective attention and game intelligence, were also correlated with game time. Sprint and RIEA were connected with game time, whereas contact injuries only correlated with sprint, and noncontact injuries with sprint and performance-IAT.Conclusion: Especially executive functions represent fundamental associations with game intelligence and game time across all age groups but not with injury incidences, whereas certain physiological abilities may contribute to more game time and less non-contact injuries depending on age.

Bidirectional Associations

Executive functions (EF) are domain-general cognitive skills that predict school success. However, less is known about the relation between EFs and science achievement. The present study examined the bidirectional associations between science achievement and children’s cognitive flexibility and working memory in a nationally representative sample of children in the United States (ECLS-K: 2011; N = 18,174). Using random intercepts cross-lagged panel modeling, results revealed a heterogeneous pattern of associations between EF and science achievement. Trait-like and construct stability emerged in the between-person and within-person estimates of EF and science. Cognitive flexibility and working memory in kindergarten each predicted science achievement in first grade. Science achievement in the fall of first grade predicted cognitive flexibility in the spring of first grade. There were also bidirectional associations between working memory and science achievement in the fall and spring of first grade. Findings from the current study reveal the complex interplay between EF and science achievement during early childhood and highlight the potential of boosting science competencies to promote growth in cognitive skills important for goal-directed activity during early schooling.
