The Longitudinal Relationship Between Diet Quality and Executive Functioning Development of Hispanic Preschoolers in Houston, Texas

BackgroundDiet quality has been found to be related to cognitive health in school-aged children. However, this relationship remains understudied among Hispanic preschool-aged children, who are vulnerable to poor dietary habits and low cognitive development due to socioeconomic, cultural, and structural disparities. ObjectiveThis longitudinal study evaluated whether the diet quality of preschool-aged children would be associated with executive functions (EFs) in later childhood. DesignThis is a secondary analysis of a longitudinal study of Hispanic preschool-aged children (age 4 and 5 years) at baseline (Time 1) and 18 months (Time 2). Participants and settingThis study included 185 mother-child dyads with complete data at Time 1, recruited through Head Start centers in Houston, TX, beginning in 2011. Main outcome measuresMothers reported on their child’s dietary intake via 3 24-hour recalls, which was used to calculate Healthy Eating Index (HEI)-2010 component and total scores. Laboratory tasks assessed cold EFs (tapping and Flexible Item Selection Tasks) and hot EFs (delay of gratification and gift-wrapping tasks). Whereas higher scores on tapping, Flexible Item Selection Task, and delay of gratification tasks represent a high EF, higher scores in gift-wrapping task represent a low EF. Statistical analyses performedHierarchical linear regression analyses assessed the relationship between diet quality, as measured by HEI-2010 total and component scores, at Time 1 (independent variables) and EF outcomes (dependent variables) at Time 2, controlling for child sex, age, body mass index z score, and EF at Time 1. ResultsHEI-2010 component score for fatty acids (b = –.13; P = .04) and seafood and plant proteins (b = .09; P = .05), were respectively related to later cold and hot EFs of Hispanic preschool-aged children. Other HEI components or the overall score did not predict EFs. ConclusionsThis study shows that specific HEI components support cold and hot EFs development among Hispanic preschool-aged children, but total HEI-2010 score does not. Experimental research is needed to assess the influence of dietary interventions on cognitive development of Hispanic preschool-aged children.

Effect of 11 Weeks of Physical Exercise on Physical Fitness and Executive Functions in Children

The aim of our study was to evaluate and compare the effects of physical exercise interventions on physical fitness and executive functions in children. Six-year-old children participated in the study and were randomly divided into physical exercise group (PE group, n = 43) and control group (C group, n = 46). The children in the PE group participated in a physical exercise program for 45 min daily, four days a week for 11 weeks. The children in the C group continued with their usual routines. Then, all the children were tested before and after the experiment for body composition (height, weight, BMI), physical fitness (20-m shuttle run test, standing long jump test, grip strength test, 4 × 10 m shuttle run test and sit and reach tests), and executive functions test (animal go/no-go task, working memory span task, simple reaction test and flexible item selection task) before and after the 11-week period. The 11 weeks of physical exercise did not significantly affect the body composition of the children (p > 0.05). The physical fitness and executive functions test results showed that 11 weeks of physical exercise interventions improves physical fitness (cardiopulmonary fitness, muscle strength, speed sensitivity and flexibility quality) and executive functions parameters (inhibitory control, working memory, the reaction time, and cognitive flexibility) in children (p < 0.05, p < 0.01). 11 weeks of physical exercise can improve the physical fitness and executive functions of six-year-old children.

Fathers’ stimulation of toddlers’ cognitive development contributes to children’s executive function skills at five years of age

ABSTRACT This multi-method study examined mothers’ and fathers’ cognitive stimulation during parent–child interactions and toddlers’ moral regulation (assessed via parent reports) as predictors of their executive functioning skills approximately 2½ years later. Forty children (23 girls and 17 boys) and their parents participated in both timepoints. Children’s moral regulation and fathers’ cognitive stimulation emerged as unique predictors of children’s performance on the Flexible Item Selection Task. For the Head-Toes-Knees-Shoulders task, a significant interaction was found for toddlers’ moral regulation and fathers’ cognitive stimulation such that children low in moral regulation were more greatly influenced by fathers’ parenting behaviour than children high in moral regulation. These findings suggest that fathers’ stimulation of children’s cognitive development works in combination with children’s moral behaviour to predict their executive functioning skills during early childhood. Future research on parenting should continue to include fathers given the important socializing role that they play in children’s development.

The Short-Term Impact of Animation on the Executive Function of Children Aged 4 to 7.

Research has shown that animation plays an important role in the development of children’s executive function (EF), and the development of EF components, inhibitory control, working memory, and cognitive flexibility, is asynchronous. Thus, this study explores the developmental trajectories and animation features (fantasy and pacing) that influence each EF component, by examining 218 children aged 4–7. Pretest information, mainly the childhood EF inventory, was provided by parents: child’s age, age of first exposure to animation, animation viewing time on weekdays and weekends, family income, and parents’ education. The children in each age group were randomly divided into four groups to watch animations comprised of different animation features. After watching, their EF were measured by a day-night task, backward digit-span task, and flexible item-selection task. The results showed that the children’s inhibitory control, working memory and cognitive flexibility levels all improved with age. Highly fantastical animations weakened children’s performance on each subsequent EF task. Pacing had no effect on any of the components of children’s EF. An interactive effect on inhibitory control was only found with fantasy in younger children; specifically, high-fantastical animations had a more pronounced short-lived weakening effect on inhibitory control in younger children (4–6 years) compared with low-fantastical animations. Future research should explore the long-term impact of content rather than the form of animation on younger children’s EF.

Executive functions in Persian-speaking preschool children with speech sound disorders and comparison with their typically developing peers

This study aimed to compare working memory, inhibitory control, and cognitive flexibility, the core components of executive functions, among two prevalent subtypes of preschool children with speech sound disorder, i.e., phonological delay (n = 16) and consistent phonological disorder (n = 15), and a group of typically developing children (n = 18). The correlation between executive function components and the accuracy of speech sound production were also investigated. Nonword repetition task and syllable repetition task were used to evaluate the phonological loop of working memory. Backward digit span was administered to examine the central executive of working memory. Cognitive flexibility was assessed using the second selection of the flexible item selection task and inhibitory control using Stroop-like and Go/No-Go tasks. The percentage consonants correct was applied to calculate the accuracy of speech sound production. Results of a one-way multivariate analysis of covariance revealed statistically significant differences between groups in the combined dependent variables after controlling for age (F(14, 80) = 17.289, p < .001, Pillai’s trace = 1.503, partial ηƞ 2 = .752). Typically developing children outperformed in all measurements of executive functions than both speech sound disorder subgroups. Moreover, children with phonological delay performed better in nonword repetition and corrected responses of Stroop-like than consistent phonological disorder group. All executive function measurements also correlated with speech sound production. The results of the present study highlight the importance of including domain-general cognitive skills in current assessment protocols for children with phonological delay and consistent phonological disorders.

On the importance of being flexible: early interrelations between affective flexibility, executive functions and anxiety symptoms in preschoolers

ABSTRACT When children are confronted with an emotional problem, affective flexibility mobilizes their cognitive and emotional resources to optimally address it. We investigated the contribution of executive functions to cognitive and affective flexibility in preschoolers. We assessed affective flexibility in 67 preschoolers (30 girls; Mmonths = 61.77, SD = 11.08 months) using an innovative measure – the Emotional Flexible Item Selection Task (EM-FIST), plus cool measures of executive functions (working memory, inhibition and cognitive flexibility), anxiety symptoms and intelligence. Findings revealed that affective flexibility improves during the preschool years. While individual differences in age and proactive inhibition predicted cognitive flexibility, a different constellation of predictors (maternal education, proactive inhibition, working memory and age) were significant for affective flexibility. Cognitive flexibility didn't contribute to affective flexibility beyond the predictors mentioned above. Anxiety exerted a negative effect on affective flexibility in a high anxious subgroup of preschoolers, but only when processing negative, relative to happy faces, supporting the Attentional Control Theory which predicts valence-related executive impairments.

Measuring Cognitive Flexibility with the Flexible Item Selection Task: From fMRI Adaptation to Individual Connectome Mapping.

Cognitive flexibility, the ability to appropriately adjust behavior in a changing environment, has been challenging to operationalize and validate in cognitive neuroscience studies. Here, we investigate neural activation and directed functional connectivity underlying cognitive flexibility using an fMRI-adapted version of the Flexible Item Selection Task (FIST) in adults (n = 32, ages 19-46 years). The fMRI-adapted FIST was reliable, showed comparable performance to the computer-based version of the task, and produced robust activation in frontoparietal, anterior cingulate, insular, and subcortical regions. During flexibility trials, participants directly engaged the left inferior frontal junction, which influenced activity in other cortical and subcortical regions. The strength of intrinsic functional connectivity between select brain regions was related to individual differences in performance on the FIST, but there was also significant individual variability in functional network topography supporting cognitive flexibility. Taken together, these results suggest that the FIST is a valid measure of cognitive flexibility, which relies on computations within a broad corticosubcortical network driven by inferior frontal junction engagement.

Assessing hot and cool executive functions in preschoolers: affective flexibility predicts emotion regulation

ABSTRACT Affective flexibility (AF) is the ability to alternate between processing emotional and non-emotional information. This hot executive function has been understudied during early development. The first aim of our investigation was to generate preliminary construct validity evidence for a new measure of AF: the Emotional Flexible Item Selection Task (EM-FIST). Second, to investigate if AF represented a better predictor of preschoolers’ emotion regulation (ER) compared to, cognitive flexibility (CF). Preschoolers (N = 56; 48.2% girls) completed AF and CF measures (also working memory and inhibitory control). ER was measured through maternal report. We found evidence of EM-FIST’s validity, as an appropriate measure of AF for preschoolers, by showing that it is related to cool executive functions’ measures and to children’s ER. Both AF and maternal level of education predicted children’s ER while CF did not. Our investigation highlights a stronger relation between ER and AF in preschoolers than with CF.

An exploration of the role of executive functions in preschoolers’ phonological development

ABSTRACTThere is limited yet compelling evidence that domain-general processes may contribute to speech sound change. This study explored whether executive functions contribute to the achievement of adult-like speech production. Children who are 4 to 5 years old, 42 with high-average speech production skills, 11 with low-average and nine with speech sound disorder (SSD), participated in a battery of executive function and speech production tasks. Performance accuracy was compared across groups and also correlated with speech sound accuracy from a single-word naming task. Children with SSD demonstrated poorer performance than other groups on forward digit span, whereas children with low-average speech skills underperformed their peers on the Flexible Item Selection Task (FIST). These preliminary results suggest that children with speech errors may have less mature working memory than peers who have mastered phonological targets earlier in development.

A FISTful of Emotion: Individual Differences in Trait Anxiety and Cognitive-Affective Flexibility During Preadolescence.

Cognitive-affective flexibility represents the ability to switch between alternative ways of processing emotional stimuli according to situational demands and individual goals. Although reduced flexibility has been implicated as a mechanism for the development of anxiety, there is very limited data on this relationship in children and adolescents. The aim of the current study was to investigate cognitive-affective flexibility in preadolescents (N=112, 50 girls, 11-12 and 13-14years old) and to examine if this ability is related to individual differences in trait anxiety. Their interplay was assessed using the modified version of the Flexible Item Selection Task (FIST; Jacques and Zelazo 2001) with non-emotional stimuli (geometrical shapes) and the Emotional FIST (EM-FIST) with emotional stimuli (emotional facial expressions). Performance on the EM-FIST indicated that across the whole age range, trials requiring greater cognitive flexibility were more demanding than nonflexible ones, as revealed by both response time and accuracy performance. Moreover, flexibility demands were higher for younger children than for older ones but only in terms of response speed. Individual differences in trait anxiety moderated the impact of flexibility only on the EM-FIST. Being flexible on the EM-FIST was more demanding for high trait anxious children than for their low trait anxious peers. Lastly, overall girls responded faster than boys, but only in the EM-FIST. These findings extend the presently limited literature concerning variability in cognitive-affective flexibility during this sensitive developmental window.

Longitudinal Associations Between Executive Functions and Intelligence in Preschool Children

Executive functions (EFs) and intelligence were examined concurrently and longitudinally in 126 preschool children. EF was assessed using the Flexible Item Selection Task (FIST) and the Behavior Rating Inventory of Executive Function–Preschool Version (BRIEF-P). Children’s intelligence was assessed using the Verbal and Performance subtests from Wechsler Preschool and Primary Scale of Intelligence–Third Edition (WPPSI-III). Results showed a significant association between verbal and nonverbal intelligence with both the FIST and the BRIEF-P. The BRIEF-P working memory scale showed the strongest relation with EF and intelligence at both time points. Results are discussed in terms of differential association between intelligence and components of EF.

When words lead to solutions: executive function deficits in preschool children with specific language impairment.

Several studies indicate that school-age children with specific language impairment (SLI) have difficulties with tasks that rely on executive functions. Whether executive function deficits in children with SLI emerge during preschool age remains unclear. Our aim was to fill this gap by investigating executive function performances in two age groups of preschoolers with and without SLI. Children with SLI (N=60; young: 53.6±5.3 months; old: 65.4±3.8 months) and age-matched control children (N=58) were tested for problem-representation ability, using the Flexible Item Selection Task (FIST), rule-use skills, using a Stroop-like Day-Night test (D/N), and planning skills, using the Tower of London test (TOL). Older children performed better than younger children did across tasks. Children with SLI had poorer performance, compared to typically developing children, on measures of problem representation, planning skills, and use of rules. Our results clearly indicate that executive function impairment is evident during the preschool period. Although old children with SLI performed better than young children with SLI, their performances were still poor, compared to those of control peers. These findings suggest that children with SLI have altered executive functioning at 53.6 months.

The development of cognitive flexibility beyond the preschool period: An investigation using a modified Flexible Item Selection Task

We explored the development of cognitive flexibility in typically developing 6-, 8-, and 10-year-olds and adults by modifying a common cognitive flexibility task, the Flexible Item Selection Task (FIST). Although performance on the standard FIST reached ceiling by 8years, FIST performance on other variations continued to improve until 10years of age. Within a detailed task analysis, we also explored working memory storage and processing components of executive function and how these contribute to the development of cognitive flexibility. The findings reinforce the notion that cognitive flexibility is a multifaceted construct but that the development of working memory contributes in part to age-related change in this ability.

Cognitive Flexibility Among Individuals With Down Syndrome: Assessing the Influence of Verbal and Nonverbal Abilities

The influences of verbal mental age (VMA) and performance mental age (PMA) on cognitive flexibility were examined among a group of participants with Down syndrome (DS), in order to disentangle the relative contributions of each. The impaired cognitive flexibility typically observed among individuals with DS in combination with uneven VMA and PMA development suggests an opportunity to further understand the developmental relationship between VMA, PMA, and cognitive flexibility. We examined the performance of 22 participants with DS on the Flexible Item Selection Task (FIST), used for measuring cognitive flexibility among preschoolers. Partial correlations revealed that only VMA was related to the FIST after controlling for PMA, highlighting the role of verbal abilities in the development of cognitive flexibility.

Brief Report: Impaired Flexible Item Selection Task (FIST) in School-Age Children with Autism Spectrum Disorders

Cognitive flexibility has been measured with inductive reasoning or explicit rule tasks in individuals with autism spectrum disorders (ASD). The Flexible Item Selection Task (FIST) differs from previous cognitive flexibility tasks in ASD research by giving children an abstract, ambiguous rule to switch. The ASD group (N=22; Mean age=8.28years, SD=1.52) achieved a lower shift percentage than the typically developing verbal mental-age control group (N=22; Mean age=6.26years, SD=0.82). There was a significant positive correlation between verbal mental age and shift percentage for children with ASD. Group differences on the FIST converge and extend prior evidence documenting an impaired ability to adapt rapidly to changes in task demands for individuals with ASD.

Sources of Cognitive Inflexibility in Set-Shifting Tasks: Insights Into Developmental Theories From Adult Data

Two experiments examined processes underlying cognitive inflexibility in set-shifting tasks typically used to assess the development of executive function in children. Adult participants performed a Flexible Item Selection Task (FIST) that requires shifting from categorizing by one dimension (e.g., color) to categorizing by a second orthogonal dimension (e.g., shape). The experiments showed performance of the FIST involves suppression of the representation of the ignored dimension; response times for selecting a target object in an oddity task immediately following were slower when the oddity target was the previously ignored stimulus of the FIST. However, proactive interference from the previously relevant stimulus dimension also impaired responding. The results are discussed with respect to two prominent theories of the source of difficulty for children and adults on dimensional shifting tasks: attentional inertia and negative priming. In contrast to prior work emphasizing one process over the other, the findings indicate that difficulty in the FIST, and by extension other set-shifting tasks, can be attributed to both the need to shift away from the previously attended representation (attentional inertia) and the need to shift to the previously ignored representation (negative priming). Results are discussed in relation to theoretical explanations for cognitive inflexibility in adults and children.

The Development of Flexibility and Abstraction in Preschool Children

This study examined the development of flexibility and abstraction in preschool children by using a newly designed Pattern Completion Task (PCT) and the Flexible Item Selection Task (FIST). In the PCT, children were presented with an incomplete pattern consisting of different-colored shapes and were asked to select the colored shape that appropriately completed the pattern. In the FIST, children were presented with three cards, each depicting items that could vary in terms of shape, size, color, and number. Children were asked to first select two cards that matched on one dimension and then to select two cards that matched on a different dimension. Both tasks were administered to 97 three-to five-year-old preschool children. Results from both the PCT and the FIST showed that the ability to flexibly shift between features of objects undergoes major development during the preschool years. Furthermore, difficult items from both tasks were significantly correlated, indicating that the same flexibility component underlies performance in both tasks.

Self‐Reflection and the Cognitive Control of Behavior: Implications for Learning

ABSTRACT— In this article, we suggest that self‐reflection and self‐control—studied under the rubric of “executive function” (EF)—have the potential to transform the way in which learning occurs, allowing for the relatively rapid emergence of new behaviors. We describe 2 lines of research that indicate that reflecting on a task and its affordances helps children to respond flexibly in a more top‐down fashion despite interference from prior learning or perceptually salient aspects of the task. Research on A‐not‐B tasks with infants and young children revealed that postswitch flexibility is an inverted U‐shaped function of number of preswitch trials. Overlearning may provide additional opportunities for reflection, in part by freeing up cognitive resources as behavior becomes automatized. Findings from the Flexible Item Selection Task with preschoolers and adults revealed that, although labeling the relevant dimension facilitates performance, performance declines when participants are prohibited from labeling. Labeling one’s perspective on a situation not only helps make that perspective an explicit object of consideration, but it may also help children access more abstract conceptual descriptions of a stimulus. Research on EF has broad implications for the way in which human learning differs from learning in other species and the way in which human learning may change over the course of development.

The Flexible Item Selection Task (FIST): A Measure of Executive Function in Preschoolers

ion and cognitive flexibility were assessed in 197 preschool children at 2, 3, 4, and 5 years of age using the Flexible Item Selection Task, a task adapted from the Visual-Verbal Test (Feldman & Drasgow, 1951). On this new inductive task, children were shown a set of 3 cards and required to select 2 cards that matched each other on 1 dimension (Selection 1) and then to select a different pair of cards that matched each other on another dimension (Selection 2). Thus, 1 of the 3 cards always had to be selected twice according to different dimensions. Two-year-olds failed to understand basic task requirements as assessed by a criterial measure. Three-year-olds did more poorly on Selection 1 than 4- and 5-year-olds (who performed near ceiling), suggesting that 3-year-olds had difficulty with the abstraction component of the task. Four-year-olds did worse than 5-year-olds on Selection 2, suggesting that they had difficulty with the cognitive flexibility component (i.e., difficulty selecting the same card on more than 1 dimension). Results are discussed in terms of the development of executive function.
