Incorporating Evidence-Based Gamification and Machine Learning to Assess Preschool Executive Function: A Feasibility Study.

Computerized assessments and digital games have become more prevalent in childhood, necessitating a systematic investigation of the effects of gamified executive function assessments on performance and engagement. This study examined the feasibility of incorporating gamification and a machine learning algorithm that adapts task difficulty to individual children's performance into a traditional executive function task (i.e., Flanker Task) with children ages 3-5. The results demonstrated that performance on a gamified version of the Flanker Task was associated with performance on the traditional version of the task and standardized academic achievement outcomes. Furthermore, gamification grounded in learning science and developmental psychology theories applied to a traditional executive function measure increased children's task enjoyment while preserving psychometric properties of the Flanker Task. Overall, this feasibility study indicates that gamification and adaptive machine learning algorithms can be successfully incorporated into executive function assessments with young children to increase enjoyment and reduce data loss with developmentally appropriate and intentional practices.

A Literature Review on the Effects of Exergames on Executive Function in Youth.

Exergames (video games that promote cognitive and physical activity simultaneously) benefit executive function in elderly populations. It has been suggested that exergames may induce larger effects than cognitive or exercise training alone, but few reviews have synthesized the causal factors of exergames on executive function from experimental research with youth. This review investigates (1) the various types of exergames and associated comparison conditions (2) the executive function outcome assessments commonly utilized in exergame research with youth (3) the efficacy of exergames by evaluating experimental studies that compared exergaming to cognitive, exercise, and passive control conditions inclusive of effect sizes and (4) the potential mechanisms underlying the changes in executive function induced from exergames. Eligible outcome data were available from 607 participants across ten studies, with the age of participants ranging from 4-21 (Mage=10.46). The findings indicate that exergames improve aspects of executive function from both acute and chronic studies. Despite the high variability of exergame contexts, dosage, populations, and outcome assessments, improvements in executive function comparing exergaming to passive control conditions were exhibited across all studies. While there is evidence of exergaming demonstrating advantages over passive control conditions, evidence is mixed when comparing exergaming to sedentary cognitive and exercise comparison conditions. Potential sources of these mixed results and future directions to address current gaps in the field are identified. As video game and technology use grows exponentially and concerns of childhood sedentary behavior and play deprivation increase, evidence-based practices that promote both physical and cognitive activity are needed.

Longitudinal investigation of executive function development employing task-based, teacher reports, and fNIRS multimethodology in 4- to 5-year-old children.

Increased focus on resting-state functional connectivity (rsFC) and the use and accessibility of functional near-infrared spectroscopy (fNIRS) have advanced knowledge on the interconnected nature of neural substrates underlying executive function (EF) development in adults and clinical populations. Less is known about the relationship between rsFC and developmental changes in EF during preschool years in typically developing children, a gap the present study addresses employing task-based assessment, teacher reports, and fNIRS multimethodology. This preregistered study contributes to our understanding of the neural basis of EF development longitudinally with 41 children ages 4-5. Changes in prefrontal cortex (PFC) rsFC utilizing fNIRS, EF measured with a common task-based assessment (Day-Night task), and teacher reports of behavior (BRIEF-P) were monitored over multiple timepoints: Initial Assessment, 72 h follow-up, 1 Month Follow-up, and 4 Month Follow-up. Measures of rsFC were strongly correlated 72 h apart, providing evidence of high rsFC measurement reliability using fNIRS with preschool-aged children. PFC rsFC was positively correlated with performance on task-based and report-based EF assessments. Children's PFC functional connectivity at rest uniquely predicted later EF, controlling for verbal IQ, age, and sex. Functional connectivity at rest using fNIRS may potentially show the rapid changes in EF development in young children, not only neurophysiologically, but also as a correlate of task-based EF performance and ecologically-relevant teacher reports of EF in a classroom context.

Keep it simple: streamlining book illustrations improves attention and comprehension in beginning readers.

This study used eye-tracking to examine whether extraneous illustration details-a common design in beginning reader storybooks-promote attentional competition and hinder learning. The study used a within-subject design with first- and second-grade children. Children (n = 60) read a story in a commercially available Standard condition and in a Streamlined condition, in which extraneous illustrations were removed while an eye-tracker recorded children's gaze shifts away from the text, fixations to extraneous illustrations, and fixations to relevant illustrations. Extraneous illustrations promoted attentional competition and hindered reading comprehension: children made more gaze shifts away from text in the Standard compared to the Streamlined condition, and reading comprehension was significantly higher in the Streamlined condition compared to the Standard condition. Importantly, fixations toward extraneous details accounted for the unique variance in reading comprehension controlling for reading proficiency and attending to relevant illustrations. Furthermore, a follow-up control experiment (n = 60) revealed that these effects did not solely stem from enhanced text saliency in the Streamlined condition and reproduced the finding of a negative relationship between fixations to extraneous details and reading comprehension. This study provides evidence that the design of reading materials can be optimized to promote literacy development in young children.

Contingent responsivity in E-books modeled from quality adult-child interactions: Effects on children's learning and attention.

Experiences of contingent responsivity during shared book reading predict better learning outcomes. However, it is unclear whether contingent responsivity from a digital book could provide similar support for children. The effects on story recall and engagement interacting with a digital book that responded contingently on children's vocalizations (contingent book) were investigated, with a focus on the role of individual differences in attention. The study used a within-subject design with 3 experiments from 90 3- to 5-year-old children. Children were presented with a contingent book and 3 noncontingent control conditions: a board book (Experiment 1), a static digital book (Experiment 2), and an animated book (Experiment 3). The use of the contingent book significantly increased children's story recall and was found to be especially useful for children with less developed attention regulation.
