Nature and Effects of Autobiographical Memory Issues in Persons with Autism Spectrum Disorders.

This comprehensive thematic review focuses on autobiographical memory (AM) in individuals with Autism spectrum disorder (ASD) with the overarching aim of informing and instructing stakeholders on this important memory structure that is often compromised in individuals with ASD. Accordingly, articles that best address the theme were selected from legitimate publishers with prime peer-reviewed journals. ASD is recognized as a neurodevelopmental disorder, often impacting on many aspects of language, cognitive, and social-emotional development. Considerable research has documented the problems children and adults with ASD frequently exhibit in language and its offshoots, the development of executive function, and theory of mind or the ability to reflect on the thoughts and feelings of self and others. These studies resulted in numerous assessments and intervention strategies designed to target the noted issues, among them problems with AM. Specialists in a variety of medical, psychological, and educational fields are exploring the nature and development of AM across the lifespan and the effects of AM weaknesses on cognitive and social-emotional factors such as self-regulation, social interactions, and self-identity. Researchers are reporting on the nature of AM deficits in persons with ASD and how AM deficits interact with or may explain other difficulties exhibited by these persons, but to date, little of this research has been incorporated into assessment and intervention strategies for persons with ASD. The aims of this article are to: 1. Describe the nature of AM, 2. Expound on assessments of AM, 3. Explain the effects of deficits in AMs on the personal narratives, self-regulation, and self-identity of persons with ASD, and 4. Explore intervention strategies to facilitate AM and the abilities of persons with ASD to tell coherent personal narratives.

Home learning environment and physical development impact children’s executive function development and literacy in rural Côte d’Ivoire

Previous research suggests executive functions mediate the effects of socioeconomic status (SES) on literacy. However, this research has primarily focused on high-income countries. Comparatively less is known about the mechanisms that link SES and literacy in low-and-middle-income countries, where childhood experiences of poverty are consistently linked to cognitive development through two sets of predictors: a child's physical development reflective of adequate nutrition and educational scaffolding at home (i.e. home learning environment). The influence of children’s physical development and home learning environment (i.e., family literacy, caregiver interactions) on executive functions and literacy was examined in 630 primary-school children (6–14 years) in rural Côte d'Ivoire. SES had an indirect effect on literacy, mediated by executive functions. The home learning environment and a child’s physical development showed distinct contributions to executive functions. The results suggest that improved home learning environments and supplemented nutrition could support executive function development and reduce the negative impact of socioeconomic disadvantage on literacy. • Poverty is linked to poor literacy outcomes in children in rural Côte d’Ivoire. • Executive functions (EF) mediate the link between SES and literacy. • Children’s home learning environments and physical development support EF. • Home learning environments and physical development show distinct contributions to EF.

Quitting rules in hybrid foraging search: From early childhood to early adulthood

In hybrid foraging, observers search for multiple instances of multiple target types. Children regularly perform such tasks (e.g., collecting LEGO pieces or looking for different teammates within a game). Quitting rules (When do you leave the search?) are important in foraging (e.g., I found enough LEGOs or teammates). However, the development of quitting behavior has not yet been experimentally studied, and it could give us significant information about executive function development. We tested 279 observers (4–25 years old) using classic feature and conjunction foraging. The results show that while children’s performance improved with age, all groups made similar "quitting" decisions roughly following optimal choices as defined by Charnov’s Marginal Value Theorem (MVT), with the youngest 4–5 years old children quitting slightly earlier. It seems that mature quitting rules in search operate relatively early in development, suggesting that those rules are quite basic aspects of the human cognition. • We studied the development of quitting rules in foraging under the Charnov's MVT. • We obtained similar results in feature/conjunction and real-world stimuli foraging. • Children as young as 4 years-old show roughly optimal quitting behavior. • Results show MVT-consistent quitting rules seem to operate early in development. • Other results replicate previous works on visual search development.

Executive functions as self-reported on the BRIEF scales in adolescents and adults with and without a history of institutionalized rearing in Russia

The Russian Federation is a country that, due to a shortage of timely family legislation, still has institutionalized children’s homes, such as orphanages and baby homes. Although family legislation is changing worldwide, with foster care becoming more common, understanding the effects of institutionalized care on individuals remains important. Notably, based on previous research, such individuals are vulnerable to deficits in executive functioning (EF). Yet Russia lacks reliable assessment instruments to evaluate EF, hindering research on EF development. The aims of this study were twofold: a) to evaluate the psychometric properties of the Behavior Rating Inventory of Executive Function (BRIEF 2) self-report form in a Russian sample; and b) to compare EF in two groups: adolescents and adults with and without a history of institutionalized care in Russia. We translated the BRIEF 2 into Russian and investigated its factor structure in participants aged 15–38 (n = 486). The Russian version showed adequate psychometric properties. Then, working with participants without self-reported ADHD (n = 402), we compared EF in adolescents and adults raised in institutional care versus those raised in biological families. The results revealed that the impact of institutionalization on EF differed in males and females, which contradicted, at least partially, previously reported findings. For males, we observed small overall effects of institutionalization on EF and small to medium negative effects in those with low SES. In females, we observed an unexpected positive effect of institutionalization on EF, especially in those with high SES. Additional research on gender attitudes in institutional care facilities is required to appraise these findings further.

An Edugame as a Didactic Tool for the Development of Executive Functions

The aim of this work is to design an edugame, created at the Laboratory H of the Department of Human, Philosophical, and Educational Sciences of the University of Salerno, as a didactic tool to assess and promote the development of executive functions in children with special educational needs attending primary school. The good functioning of executive functions is assessed through specific tests and is a predictor of the prerequisites necessary for school learning and the development of social skills. The edugame prototype will be composed of several interactive games to allow students to train some cognitive skills at an increasing level. The prototype will consist of several interactive games to enable students to train certain cognitive skills at an increasing level. In the first design phase, work will focus on one of the components of executive functions: inhibition. In fact, the first game was implemented starting from an application created in Lab-H, built on the basis of the circle drawing task, to assess the capacity for inhibition.

Studying hot executive function in infancy: Insights from research on emotional development

Recent calls have urged to bridge the fields of emotional and cognitive development to advance theoretical and empirical pursuits. Yet, despite notable overlap between research on executive function and emotion regulation, a uniting theory that informs future avenues of research is lacking. Infants are known to lack emotion regulation skills, as they are developing the abilities to regulate their emotions and coordinated responses. However, the field of emotional development demonstrates that at an early age, infants are adept at regulating their behaviors in response to others emotional reactions. Moreover, although classic delay of gratification tasks are fairly ecological measures, rarely are rules expressed to infants without emotions. This paper draws from recent interest in hot executive function to link infancy research on executive function and emotion. Hot executive function lends itself as a useful construct in this endeavor because it unites the study emotion and executive function. We offer a perspective that refines hot executive function within prominent emotion theories while discussing infant executive function and emotion empirical pursuits. Our perspective presents reliable paradigms from the field of emotional development to serve as tools for studying the development of hot executive function.

Comparing Executive Functioning in the School Readiness of Hungarian and Kenyan Preschoolers

Cross-national comparisons represent an avenue for investigating milestones achieved by one region that can help improve standards in another country. This study compares the development of executive functioning in Hungarian and Kenyan preschoolers as they prepare for school readiness. The study's cross-sectional design entailed sampling preschoolers from Hungary (n = 187) and Kenya (n = 420) aged between 4 and 8 years nested in 35 classrooms. Preschool class teachers rated the children's executive functioning using the Childhood Executive Functioning Inventory (CHEXI). The two-factor structure of the CHEXI demonstrated a strong measurement invariance for the two countries, Hungary and Kenya. Significant gender differences were noted on both subscales in the Hungarian sample but not in the Kenyan preschoolers. Additionally, no differences were found in the executive functioning of boys from both countries. However, the girls exhibited variances in the inhibition subscale. Contrary to expectations, no linear mixed effects were observed for country or the interactions between age and country apropos difficulties related to inhibition and total executive functioning except for working memory. Better working memory skills noted in the Hungarian sample were attributed to a superior preschool education system.

The Structural Relationship Between Mothers’ Smart Media Literacy, Smart Media Mediation, Young Children’s Overdependence on Smart Devices, and Executive Function

Objectives: This study aimed to examine the structural relationships among mothers’ smart media literacy, smart media mediation, young children’s overdependence on smart devices, and executive function.Methods: The Participants comprised 205 children aged 3 to 5 years old, and their mothers. The Early Years Toolbox (EYT) was used to measure young children’s executive function. The data obtained were analyzed using Cronbach’s α, frequency analysis, descriptive statistics, one-way ANOVA analysis, and partial correlation analysis with SPSS 25.0. Bootstrapping was used to examine the mediating effect while the Structural Equation Model (SEM) analysis was performed using AMOS 22.0.Results: First, young children’s executive function was positively associated with mothers’ smart media literacy and smart media mediation but negatively associated with young children’s overdependence on smart devices. Second, mothers’ smart media mediation and young children’s overdependence on smart devices sequentially mediated the relationship between mothers’ smart media literacy and young children’s executive function. It was also found that mothers’ smart media mediation partially mediated the relationship between mothers’ smart media literacy and young children’s executive function.Conclusion: These findings highlight the importance of mothers’ smart media literacy and smart media mediation for young children’s executive function and emphasize the need of prevention for overdependence on smart devices in facilitating executive function development in early childhood.

Executive function assessment: Adaptation of the Amsterdam executive function inventory using Spanish first-year university students from two knowledge areas.

Many university students have difficulties in adapting to autonomous learning due to executive functioning deficits. In the Spanish university context, there is a lack of reliable validated instruments for the evaluation of executive functioning. In this sense, the aim of this research is to present the process of adaptation and validation of the Amsterdam Executive Function Inventory (AEFI) for the evaluation of executive functioning in the Spanish context. This study integrates two sequential processes: questionnaire translation and back-translation, and evaluation of the psychometric properties (exploratory and confirmatory factor analysis were conducted), reliability, validity and multigroup analysis to identify factorial invariance. An online questionnaire was used for data collection and R package lavaan software was administered to a sample of 519 first-year university students (270 females and 249 males). The exploratory factor analysis evidenced an interna structure of three factors with adequate internal consistency (Cronbach's alpha higher than 0.70), endorsed in the confirmatory factor analysis that indicated an adequate goodness-of-fit-indexes for the model. The composite reliability showed values between 0.74 and 0.82, and the convergent (average variance extracted values ranged from 0.50 to 0.61) and discriminant validity were adequate. A multigroup-analysis showed the invariance factorial through the difference in the RMSEA, CFI and TLI index, performed both in the model comparison according to gender and academic disciplines. The AEFI adapted for Spanish has practical implications for the management of university students, as it can facilitate the improvement of university policies designed to foster the development of executive functions, specifically in first-year students.

Executive Function and Theory of Mind in Children Living in Poverty: A Short-term Longitudinal Study

ABSTRACT The early childhood years are critical for developing executive function (EF) and theory of mind (ToM). Prior literature suggests a robust relationship between EF and ToM; however, this relationship has seldom been investigated in children living in poverty. In addition, few studies have employed comprehensive ToM measures to explore how EF relates to different components of ToM. This study examined longitudinal relations between EF and ToM among 86 preschool children (3- to 5-year-old) attending Head Start programs in the United States. Children completed two EF tasks and a 5-task ToM battery twice, four months apart. Results showed that, for children living in poverty, early EF did not significantly predict later ToM as a composite after controlling for significant covariates. However, the emotionally salient component of ToM predicted children’s later Stroop performance, above and beyond several controls. Findings suggest that for impoverished children living in the U.S., the development of emotional perspective-taking may be particularly important for EF development compared to other components of ToM.

Early Risk of Tobacco Smoke Exposure and Preschoolers' Hot and Cool Inhibitory Control: Promotive and Protective Roles of Maternal Positivity in Early Mother-child Interaction.

Early tobacco smoke exposure (TSE) in utero and/or during the first years after birth poses threats to the development of child executive functioning and self-regulation skills, including inhibitory control. Efforts are still needed to examine under what conditions such effects may occur and thus identify modifiable intervention targets. In addition, a distinction between cool and hot inhibitory control is also important to obtain greater nuance in such links. The cool inhibitory control refers to children's suppression of prepotent automatic responses to a distracting stimulus in solving arbitrary and decontextualized problems, whereas the hot inhibitory control refers to children's control of impulse in motivationally and emotionally high-stake situations. Using data derived from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development, we examined the links between early risk of TSE and preschoolers' hot and cool inhibitory control and tested the potential promotive/protective roles of maternal positivity in early mother-child interactions. Results indicate that early risk of TSE was negatively linked to child cool inhibitory control when maternal positivity was low, but this link was nonsignificant when maternal positivity was high (i.e., the protective role of maternal positivity). The link between early risk of TSE and child later hot inhibitory control was not moderated by maternal positivity; instead, early risk of TSE and maternal positivity were negatively and positively associated with child hot inhibitory control above and beyond each other, respectively (i.e., the promotive role of maternal positivity). Accordingly, building a tobacco-free environment during pregnancy and infancy likely yields long-term benefits for child self-regulation development. Improving early mothering may offset the negative link between early TSE and child cool inhibitory control and also facilitate child hot inhibitory control even in the face of early TSE.

The Construction of Executive Function in Early Development: The Pragmatics of Action and Gestures

The position I take in this paper is that investigation of the construction and development of executive function (EF) and cognitive self-regulation must give children the opportunity to behave with initiative, as the agents they are. It must be based on children’s goal-directed behaviours and the challenges they face to achieve their own goals from the last third of the first year of life. It must consider children’s interests, the ecological validity of the situations, and the social context. Investigation into the origin and early development of cognitive self-regulation must be firmly anchored within a developmental framework. I will suggest that such a developmental framework is provided by the functional turn developed in the School of Geneva in the 1970s and its influence on the Pragmatics of the Object perspective. According to this pragmatic approach, actions and (private) gestures are central in the emergence and construction of EF.

The Directionality of the Relationship Between Executive Functions and Language Skills: A Literature Review.

It has been demonstrated that executive functions play a significant role in different aspects of the development of children. Development of language is also one of the most important accomplishments of the preschool years, and it has been linked to many outcomes in life. Despite substantial research demonstrating the association between executive function and language development in childhood, only a handful of studies have examined the direction of the developmental pathways between EF skills and language skills, therefore little is known about how these two constructs are connected. In this review paper, we discuss three possible directional relationships between EFs and language development throughout childhood. First, we discuss how EF might affect language functioning. Next, we discuss how language functioning might affect EF. Lastly, we consider other possible relationships between EF and language. Given that children with better EF and language skills are more likely to succeed in educational settings and demonstrate greater social–emotional competencies, investigating the relationship between EF and language in the preschool period provides insight into mechanisms that have not been extensively studied. Furthermore, it could create new opportunities for designing effective and efficient interventions aimed at addressing EF and language deficits during the preschool period which could in turn influence later development.

A Systematic Review of the Link Between Autism Spectrum Disorder and Acetaminophen: A Mystery to Resolve.

The purpose of this study is to review the published papers investigating maternal acetaminophen (AP) use during pregnancy and its effect on the offspring's neurodevelopment, particularly autism spectrum disorders (ASD). Acetaminophen is an over-the-counter analgesic and antipyretic considered safe in pregnancy. Recent studies have found an association between acetaminophen and immune system alterations like asthma and adverse neurodevelopmental outcomes. We used online databases (PubMed/Medline/PubMed Central, Science Direct, and Google Scholar) to search the studies relevant to our topic. We screened the papers by titles, abstracts, and then full-text availability. The screened articles were checked for eligibility using relevant quality assessment tools for each study design, extracting and analyzing the data. We finalized 30 studies after the screening; 14 were ineligible. Our final selection included 16 high-quality papers - 13 prospective cohort studies, two review articles, and one meta-analysis.We found a wide range of neurodevelopmental outcomes in our data collection. So, we included autism spectrum disorders, intelligent quotient (IQ), attention-deficit/hyperactivity disorder (ADHD), isolated language, attention and executive function, communication, behavior, and psychomotor development. All studies showed an association between acetaminophen use and listed neurodevelopmental outcomes. Long-term use, increased dose, and frequency were associated with a stronger association. We extracted collective evidence from 16 studies suggesting acetaminophen's role in developing adverse neurodevelopmental outcomes. It is urgent to do more research on this association before pregnant women can be cautioned about the precise use of acetaminophen.

Associations between Fundamental Movement Skills, Physical Fitness, Motor Competency, Physical Activity, and Executive Functions in Pre-School Age Children: A Systematic Review.

Previous empirical research and reviews have suggested that the level of fundamental movement skills (FMS), motor competence (MC), physical activity (PA), or physical fitness seem to directly influence the executive functions (EFs) in school aged children. However, there is no available comprehensive review of whether the exact links between motor constructs and EFs also exist in the preschool period, even though preschool age is the critical period for developing EFs. Therefore, this study aimed to systematically review the evidence on the association between FMS, MC, PA, PF, and EFs. To conduct the systematic review, we utilized searches using Web of Science, PubMed, and EBSCO (including SPORTDiscus and Academic Search Premier). We included studies that examined associations between one or all of the four motor constructs with EFs among typically developing children aged 3–6 years, published between January 2010 and October 2021. A total of 15 studies met the inclusion criteria, of which four were randomized controlled trials, three were longitudinal studies, four were cohort studies, and four were cross-sectional studies. We found weak correlations or insufficient evidence for associations between FMS, PA, PF, and EFs. However, there was strong evidence for a moderately strong association between MC and working memory, a moderately weak association between MC and inhibition, and inadequate evidence for a weak to moderate association between MC and shifting. In addition, only half of the included studies were methodologically high-quality studies. Specifically, a questionable design selection of research samples might bias the strength of evaluated associations. We also found significant diversity in the diagnostic tools used for assessing and measuring motor and EFs domains. Our findings support the assumption that motor competencies level, which contains physical capacity and cognitive components, could be significantly linked to EF development from a preschool age. Therefore, we suggest that future studies focus more on clinical trial design, combining movement interventions with different levels of cognitive components, for the purposive development of EFs in preschool-aged children.

Questions that Fuel the Mind: Exploring the Associations between Teacher-Child Higher-Level Interaction and Preschoolers’ Development of Executive Functions

ABSTRACT Recent research has provided mixed evidence on the promise of classroom-based interventions for supporting young children’s development of executive functions (EF). To advance intervention efforts, it is necessary to identify specific types of interactions that might support the development of EF in early childhood. Through a correlational design, this study explores the relationship between higher-level, teacher-child interaction in Head Start classrooms and children’s EF. Higher-level interaction was measured using both global and fine-grained approaches. Children completed task-based assessments targeting individual components of EF at the beginning and end of a preschool year. Research Findings: Hierarchical linear modeling revealed that the frequency of teachers’ higher-level questions was significantly associated with a spring composite EF score and spring cognitive flexibility, controlling for fall scores and other covariates. A global measure of higher-level interaction was negatively associated with spring inhibitory control, controlling for fall scores. Neither measure of higher-level interaction was associated with spring working memory. Practice and Policy: This study has methodological implications for the value in measuring teacher-child interaction using more fine-grained approaches in order to reveal important associations with child outcomes. In relation to practice, this study suggests that intervention efforts to support teachers’ use of higher-level interaction strategies may support children’s development of EF.

Inhibitory control as a significant predictor of academic performance in Chinese high schoolers

ABSTRACT Studies investigating the relationship between cognitive function and academic performance have recently shifted focus from differences in intelligence to executive function. To date, these studies have focused disproportionately on samples recruited from Western countries, despite evidence in support of cultural differences in the development of executive function. To address this gap, the present study investigated whether differences in two dimensions of executive function, inhibitory and attentional control, could predict academic performance in a sample of Chinese adolescents (n = 42). Participants reported on demographic details and completed both the Simon task and Attention Network Test. Data were analyzed using multiple linear regression controlling for gender, age, SES, English language proficiency, processing speed, and fluid intelligence. Results showed that one index of inhibitory control derived from non-cue trials on the Attention Network Test explained a significant amount of unique variance in academic performance. Our findings provide evidence that executive function, specifically inhibitory control, plays a significant role in academic performance.

Overweight and executive functions, psychological and behavioral profile of Spanish adolescents.

The prevalence of overweight and obesity among children and adolescents has risen dramatically increasing a major risk factor for non-communicable diseases and cognitive dysfunctions. This study aimed to analyze differences in the executive function´s development between overweight and normal-weight adolescents. As a secondary objective, we aimed to assess differences in adolescents’ psychological and behavioral profiles between groups. In order to achieve the study's aim, 105 adolescent students (17.61 ± 7.43 years) completed an online questionnaire that analyzed variables regarding their executive functions’ processes, their psychological and physical health as well as lifestyle habits. Results showed that executive functions development is associated with adolescent weight. A higher range of weight presents a lower ability to assess abstract reasoning and to shift cognitive strategies. Nevertheless, no differences were found between groups in the capacity to hold information in mind nor the ability to control impulsive responses. Furthermore, groups showed differences in the number of meals and gastritis, but no significant differences have been found in lifestyle variables such as mobile usage, smoking, physical activity, and hours of sleep per day. The results from the present study could be used to implement multidisciplinary programs to develop healthier habits.

EXAMINATION OF EXECUTIVE FUNCTIONS AFFECTING SPORTS PERFORMANCE IN THE CONTEXT OF ATHLETE EXPERIENCE

Introduction: In our research, we investigated the components, executive functions, and cognitive abilities underlying decision-making in sports performance using a computer-based test system. To define the athlete experience, we classified athletes according to an exact, unambiguous definition following international terminology, based on their performance, achievement, playing age, and sport's popularity. We hypothesize that team athlete with significant athletic experience will perform better on the executive function test. 
 Methods: A cross-sectional study was conducted on team athletes N=52. The VTS-DT test was used to measure executive function. The classification of athlete experience was based on an internationally accepted taxonomy defined with scientific precision (SWANNN, 2015). 
 Results: When classified by athlete experience, the athletes we studied fell into amateur and elite categories. The DT/S2 scores of the two groups were compared based on each factor. We obtained trend-like correlations for the factors 'number of reactions', 'number of stimulations,' and 'number of good responses. Correlation analysis was performed between the factors on a group-by-group basis. When examining the relationship between reaction time, we found that there is a strong relationship with the number of stimulations (amateurs: r = -0.80; elite athletes: r = -0.87) since the faster someone is (i.e., the less reaction time), the more times they can respond to stimulations. Looking at the results for elite athletes, we also observe a moderately strong relationship between reaction time and the number of good responses (r = -0.68). We may suggest that experienced athletes could produce better responses faster than less professional athletes.
 Conclusions: Our hypotheses were partially confirmed, as we found a trend-like correlation that elite athletes scored higher on the DT test, which examined athletes' executive functions in a complex, adaptive way. Our research demonstrates that, on the one hand, it is worthwhile for coaches to build on experienced athletes when assembling a team, in addition to the momentum of young athletes, and that the development of executive functions and cognitive skills can improve the performance of athletes.

Development of visual sustained selective attention and response inhibition in deaf children.

Studies of deaf and hard-of-hearing (henceforth, deaf) children tend to make comparisons with typically hearing children for the purpose of either identifying deficits to be remediated or understanding the impact of auditory deprivation on visual or domain general processing. Here, we eschew these clinical and theoretical aims, seeking instead to understand factors that explain variability in cognitive function within deaf children. A total of 108 bilingual deaf children ages 7-13 years who use both English and American Sign Language (ASL) participated in a longitudinal study of executive function (EF) development. We report longitudinal data from a visual continuous performance task that measured sustained selective attention and response inhibition. Results show that the impact of deafness on these processes is negligible, but that language skills have a positive relationship with both: better English abilities were associated with better selective sustained attention, and better ASL abilities with better response inhibition. The relationship between sustained selective attention and English abilities may reflect the cognitive demands of spoken language acquisition for deaf children, whereas better ASL abilities may promote an "inner voice," associated with improved response inhibition. The current study cannot conclusively demonstrate causality or directionality of effects. However, these data highlight the importance of studies that focus on atypical individuals, for whom the relationships between language and cognition may be different from those observed in typically developing populations.
