Impact of Prescribed Exercise on the Physical and Cognitive Health of Adults with Down Syndrome: The MinDSets Study

The duplication of chromosome 21, as evidenced in Down Syndrome (DS), has been linked to contraindications to health, such as chronotropic and respiratory incompetence, neuromuscular conditions, and impaired cognitive functioning. The purpose of this study was to examine the effects of eight weeks of prescribed exercise and/or cognitive training on the physical and cognitive health of adults with DS. Eighty-three participants (age 27.1 ± 8.0 years) across five continents participated. Physical fitness was assessed using a modified version of the six-minute walk test (6MWT), while cognitive and executive functions were assessed using the Corsi block test, the Sustained-Attention-To-Response Task (SART), and the Stroop task (STROOP). All were completed pre- and post-intervention. Participants were assigned to eight weeks of either exercise (EXE), 3 × 30 min of walking/jogging per week, cognitive training (COG) 6 × ~20 min per week, a combined group (COM), and a control group (CON) engaging in no intervention. 6MWT distance increased by 11.4% for EXE and 9.9% for COM (p < 0.05). For SART, there were positive significant interactions between the number of correct and incorrect responses from pre- to post-intervention when participants were asked to refrain from a response (NO-GO-trials) across all experimental groups (p < 0.05). There were positive significant interactions in the number of correct, incorrect, and timeout incompatible responses for STROOP in EXE, COG, and COM (p < 0.05). Walking generated a cognitive load attributed to heightened levels of vigilance and decision-making, suggesting that exercise should be adopted within the DS community to promote physical and cognitive well-being.

Deep Learning Approaches for Electroencephalography (EEG)-Based User Response Prediction

In deep learning, finding the best algorithms for time series data can be challenging due to its stochastic and nonlinear nature. This study endeavours to address the challenges posed by a 10-class classification and binary classification problem employing deep learning algorithms. We collected Electroencephalography (EEG) data from participants engaged in the Corsi Block Tapping Task, utilizing various combinations of Convolutional Neural Network (CNN), Long Short-Term Memory (LSTM), and Bidirectional LSTM (BiLSTM) models across multiple layers to achieve the highest accuracy across different frequency bands - namely, beta band (14-30 Hz), alpha band (8-13 Hz), theta band (4-8 Hz), and delta band (0.5-4.35 Hz). Our findings in the context of the 10-class classification problem highlight the superior performance of the 1 CNN + 4 linear layers model, boasting an accuracy of 64.47%. In the realm of binary classification, the 1 LSTM + 4 linear layers model emerged as the top performer, achieving an impressive accuracy of 93.30%. Notably, the beta wave exhibited enhanced predictive capabilities. These results hold promising implications for the design of brain-computer interface experiments, where specific brain regions can predict responses with heightened accuracy. Furthermore, future applications may encompass the development of cognitive systems where both time and accuracy play pivotal roles.

The Influence of Classroom Size and Window View on Young Children's Executive Functions and Physiological Responses, Based on VR Technology.

Despite the increasing enrollment of young children in childcare institutes, there have been few empirical studies on the effects of spatial elements on their development. This study explored the impact of preschool classroom size (large vs. small) and window view (natural vs. built environment) on young children's executive functions and physiological stress responses, using cortisol and heart rate variability (HRV) as indicators and employing virtual reality (VR) technology. Out of 144 participants aged 61-85 months, three were excluded due to missing values and outliers. Executive function tests were administered, and saliva samples were collected before and after VR exposure; HRV data were gathered during the experience. ANCOVA results indicated significant improvements in cognitive flexibility, as measured based on the Dimensional Change Card Sorting task, in the large classroom condition, and a marginally significant decrease in visuo-spatial working memory, as measured with the Corsi block task, in the small classroom condition. The classroom size conditions did not significantly differ in cortisol response, but the large classroom condition showed marginally significant HRV indices, suggesting increased relaxation. No significant effects on executive functions or physiological responses were found in either window view condition. Overall, the findings suggest that classroom size may influence young children's cognitive flexibility.

Comparison Between Cardiorespiratory Fitness and Functions of Cognitive Control in Adolescents: A Tracking Study of 3Years.

Compare tracking groups with cognitive control functions and plasma brain-derived neurotrophic factors concentrations from childhood to adolescence. This is a prospective study with 3years of follow-up. At baseline, data from 394 individuals were collected (11.7y), and data were obtained from 134 adolescents (14.9y) at the 3-year follow-up. At both time points, anthropometric and maximal oxygen uptake data were collected. Cardiorespiratory fitness (CRF) groups were classified into high or low CRF. At follow-up, cognitive outcomes were collected via the Stroop and Corsi block test; plasma brain-derived neurotrophic factors concentrations were also analyzed. Comparisons demonstrated that maintaining high CRF over 3years results in shorter reaction time, better inhibitory control, and higher working memory values. Likewise, the group that moved from low to high CRF over 3years presented better reaction time. Plasma brain-derived neurotrophic factors concentrations were higher for the group that increased its CRF over the 3years in relation to the low-low group (90.58pg·mL-1; P = .004). However, after scaling by an allometric approach, differences were only found for reaction time and working memory between high-high and high-low groups. Maintaining high CRF over 3years was positively related to reaction time and working memory in relation to adolescents that decreased their levels of CRF.

The Effects of Adolescents' Participation in Video Games on Cognitive Function and Motor Control Skills.

There is still a lack of understanding of the productive areas of video game participation. Therefore, in order to observe positive effects and changes in game participation, this study examines the effects of game participation on the cognitive function and motor skills from 130 adolescents. To evaluate the participants' test performance, a cognitive function and motor control skill test program consisting of 10 tests were used (Trail Making, Corsi block, Tower of London, shooting game tasks, etc.). Differences in test performances between groups were verified using one-way ANOVA and an independent t-test. The results were as follows: first, there was no difference between groups according to the frequency of game participation in every test performance. Second, the results of this study showed statistically significant differences between groups according to the play time of game participation in several test performances (Key-mapping: p = 0.40; score of Grid Shot: p = 0.01, 0.07; score of Sphere Track: p = 0.12, 0.21; accuracy of Sphere Track: p = 0.12, 0.16). Also, all the effects' size results were confirmed as medium (Cohen's f > 0.20 and <0.40). Third, high school students only showed statistically significant higher results in a Multi-tasking test performance than middle school students, and the results of the effect size were confirmed to be middle and large (Multi-tasking1: p = 0.00, Cohen's d = 0.830; Multi-tasking2: p = 0.05, Cohen's d = 0.501). The results of this study imply the need to regard game participation as a behavior that can contribute to adolescents' cognitive psychological health.

Does the Stroop Task Induce Ego Depletion Effect? Brief Experimental Study Amoing Indonesian Students

While there are pervasive canonical examples of the Stroop task effectiveness to induce the ego depletion effect, there were much less is known about how this paradigm used in the Indonesian samples. Our current study aims to investigate whether the Indonesian version of Stroop task would generate ego depletion effect. Seventy-five university students between the ages of 18 and 21 were randomly assigned into three groups, two depletion and one control conditions. The first and second groups respectively received incongruent and congruent Stroop stimulus through Psytoolkit online experimental psychology platform, and the third group received no stimulus. We administered the online Corsi block test to participants in the experimental group and compared their scores with the control group to determine whether or not ego depletion effect, induced by the Stroop task, had occurred. The findings of this online experimental study demonstrate that there were no significant differences (p &gt; .001) in participants' spatial span scores across three groups. The findings of this study suggest that performing the Stroop task to elicit the ego depletion effect should be carried out with caution. Its implication and recommendation for future research are discussed in the paper.

Functional Training and Dual-Task Training Improve the Executive Function of Older Women.

Functional training (FT) is a type of multicomponent training with emphasis on activities of daily living that stimulate different physical capacities in only one session. Dual-task training (DTT) is a type of training that simultaneously applies cognitive and motor stimuli. We investigated the effects of sixteen weeks of FT and DTT and eight weeks of detraining on older women's inhibitory control, working memory, and cognitive flexibility. Sixty-two older women (66.9 ± 5.4 years; 27.7 ± 3.9 kg/m2) completed a 16-week intervention program comprising the FT (n = 31) and DTT (n = 31), and 43 returned after the detraining period. We used the Stroop Color Word Color test to evaluate inhibitory control, the Corsi Block Test to assess working memory, and the Trail Making Test to evaluate cognitive flexibility. Only DTT reduced the congruent response time between the pre-test and post-test (d= -0.64; p < 0.001), with no difference between the post-test and the detraining values (d = 1.13; p < 0.001). Both groups reduced the incongruent response time between the pre-test and post-test (FT: d = -0.61; p = 0.002; DTT: d= -0.59; p = 0.002) without a difference between groups. There were no significant differences in working memory and cognitive flexibility. Sixteen weeks of FT and DTT increased the inhibitory control of older women but not the working memory and cognitive flexibility, and these effects persisted after eight weeks of detraining.

Internet Addiction And Self-Learning: The Impact Of Uncontrolled Smartphone Use On Teenagers' Educational Outcomes

The study aimed to reveal the relationship between indiscriminate use of smartphones and academic achievement among high school adolescents aged between 15 and 19, for a sample of 52 girls and boys. We employed a correlational descriptive approach to explore the association between two variables, using both the Pearson correlation coefficient and the T-test for analysis of the Internet Addiction Test (IAT) of Youg and the forward digit span test to measure the phonological loop, the reverse digit span test to measure the central administrator, and the Corsi block test to provide a framework for the theoretical and methodological analysis of blind uses of the digital tool among adolescents, to verify the existence of a statistically significant correlation between the uncontrolled use of smartphones and academic success.

Effect of tele-yoga on aerobic capacity, respiratory muscle strength, and cognitive performance in patients with obstructive sleep apnea syndrome

BackgroundObstructive sleep apnea syndrome (OSAS) causes a decrease in aerobic capacity, respiratory muscle strength, and cognitive function, negatively affecting health-related quality of life. ObjectivesThis study aimed to compare aerobic capacity, respiratory muscle strength, cognitive performance, functional capacity, sleep quality and daytime sleepiness in OSAS patients practicing and not practicing tele-yoga (TY). Methods44 OSAS patients (40 M, 4F) were randomized into TY and control groups. TY group underwent live synchronous group-based TY sessions, 60 min/day, three days/week, for 12 weeks. Control group performed unsupervised thoracic expansion exercises at home 4 times daily for 12 weeks. The following were evaluated at baseline and at the end of the 6th and 12th weeks: inspiratory and expiratory respiratory muscle strength (MIP, MEP), cardiopulmonary exercise test, Corsi Block Tapping Test (CBTT) and Stroop TBAG test, six-minute walk test (6MWT), Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS). ResultsTY significantly improved MIP, and exercise test parameters (VE, HRmax,%HR, heart rate recovery in the first minute and RQmax), CBTT (forward) and Stroop TBAG test scores (parts of 3,4,5) compared to the controls (p<0.05). There were no significant changes 6MWT in the TY group compared to the control group (p > 0.05). Sleep duration (min), sleep efficiency, sleep quality of PSQI and ESS score improved significantly in the TY group compared to the control group (p < 0.05). ConclusionWe suggest including TY intervention as a method of exercise in addition to CPAP treatments since it improves the health-related parameters of OSAS patients.

Don't disturb my circles: The effect of fine arts training on visuospatial ability in students.

Origami, drawing and colouring are artistic activities that can be beneficial for cognitive abilities or emotional well-being. However, there is a lack of studies that would investigate and compare these activities and their effects within the spatial abilities' domain. The aim of this study was to investigate if and how participating in three artistic activities-colouring, drawing or origami-can enhance spatial abilities. A total of 73 young adults participated in one of the three activities organized as a 7-session training, distributed every third day. Measures of spatial abilities (Spatial Reconstruction Task [SRT]), Mental Rotation Task [MRT]), Santa Barbara Solids Task [SBST]), and Corsi Block Tapping Task [Corsi]) were administered before (pretest) and after (posttest) the training, as well as at the 6-month follow-up). The Intrinsic Motivation Inventory (IMI) was administered at the posttest. The results showed no significant interaction between the training group and the measurement time point for the spatial ability tasks. Nevertheless, effect sizes at posttest favor origami and drawing in enhancing more complex spatial abilities (MRT for origami and drawing; SBST for origami; Corsi for drawing), and colouring in strengthening spatial perception (SRT). Some effects have remained for a longer period of time. Origami led to a greater pressure and tension, and colouring to higher interest and enjoyment. These results suggest that artistic activities can potentially contribute to the strengthening of spatial abilities, but it is advised to presented them in a way that reduces frustration and increase participant's enjoyment.

Audio-Corsi: a novel system to evaluate audio-spatial memory skills.

Spatial memory (SM) is a multimodal representation of the external world, which different sensory inputs can mediate. It is essential in accomplishing everyday activities and strongly correlates with sleep processes. However, despite valuable knowledge of the spatial mechanisms in the visual modality, the multi-sensory aspects of SM have yet to be thoroughly investigated due to a lack of proper technologies.This work presents a novel acoustic system built around 3D audio spatial technology. Our goal was to examine if an afternoon nap can improve memory performance, measured through the acoustic version of the Corsi Block Tapping Task (CBTT), named Audio-Corsi. We tested five adults over two days. During one of the two days (Wake), participants performed the Audio-Corsi before (Pre) and after (Post) a wake resting period; while the other day (Sleep), participants performed the Audio-Corsi before (Pre) and after (Post) a nap. Day orders were randomized. We calculated the memory span for the Pre and Post session in both the Wake and Sleep days. Preliminary results show a significant difference in the memory span between the Wake and Sleep days. Specifically, memory span decreased between the pre-and post-test during the wake day. The opposite trend was found for the sleep day. Results indicate that SM can be improved by sleeping also in the acoustic modality other than the visual one.Clinical Relevance- The technology and procedure we designed and developed could be suitable in clinical and experimental settings to study high-level cognitive skills in the auditory sensory modality and their relationship with sleep, especially when vision is absent or distorted (i.e. blindness).

The Effect of Cognitive Task Complexity on Healthy Gait in the Walking Corsi Test.

Dual-task activities are essential within everyday life, requiring visual-spatial memory (VSM) and mobility skills. Navigational memory is an important component of VSM needed to carry out everyday activities, but this is often not included in traditional tests such as the Corsi block tapping test (CBT). The Walking Corsi Test (WalCT) allows both VSM and navigational memory to be tested together, as well as allowing measures of gait to be collected, thus providing a more complete understanding of dual-task function. The aim of this study was to investigate the effect of an increasingly complex cognitive task on gait in a healthy adult population, using the WalCT and body-worn inertial measurement unit (IMU) sensors. Participants completed both the CBT and WalCT, where they were asked to replicate increasingly complex sequences until they were no longer able to carry this out correctly. IMU sensors were worn on the shins throughout the WalCT to assess changes in gait as task complexity increased. Results showed that there were significant differences in several gait parameters between completing a relatively simple cognitive task and completing a complex task. The type of memory used also appeared to have an impact on some gait variables. This indicates that even within a healthy population, gait is affected by cognitive task complexity, which may limit function in everyday dual-task activities.

626-P: Integrated Approach of Yoga Therapy (IAYT) Improves Cerebrovascular Functions and Prefrontal Hemodynamic Activities Related to Cognition in Type 2 Diabetes

The present study aimed to assess the integrated approach of yoga therapy (IAYT) effect on cerebrovascular reactivity in middle cerebral artery (MCA), prefrontal cortex (PFC) oxygenation and cognitive functions in patients with T2DM. Method: 75 patients were randomized to the IAYT group [n=38; 07 female; mean age 52.95 (8.20) years] and the waitlist control group [n=37; 06female; mean age (SD) 49.62 (10.94) years]. The cerebral blood flow and prefrontal hemodynamic activities were assessed using transcranial doppler and functional near-infrared spectroscopy, respectively, during resting and cognitive performance. IAYT group participants received 3 months of intervention and assessments were done at baseline (0-week), mid (after 6-week), and post (after 12-week). Results: After a 12-week intervention, participants of the yoga group showed improved accuracy and reaction time in a 2-back condition of the working memory task, and the scores of the Corsi Block Tapping task. Further, cerebrovascular changes were observed in the middle cerebral artery, which showed increased peak systolic velocity, mean blood flow velocity, end-diastolic velocity, and breath-holding index after 12-week yoga practice. The oxygenation was also higher at dorsolateral, dorsomedial, and ventromedial and orbitofrontal PFC in the 12th week of the yoga practitioners group compared to the control group. Moreover, during 2-back working memory task, yoga group participants demonstrated increased oxygenation at dorsolateral PFC compared to pre and higher oxygenation at dorsolateral, ventrolateral, ventromedial and orbitofrontal PFC compared to control group. Conclusion: The results suggest that IAYT practice may improve cognitive functions by improving cerebral blood flow through the middle cerebral artery and hemodynamic activities in the prefrontal regions in patients with T2DM.

Combination of Vestibular Rehabilitation and Galvanic VestibularStimulation ImprovesVerbal andVisuospatial Memory: A Randomized Control Trial in Patients with Amnestic Mild Cognitive Impairment

Background and Aim: Considering the critical input of the vestibular system to the hippocampus as an area involved in cognition, and vestibular disorders reported in patients with amnestic Mild Cognitive Impairment (aMCI), we aimed to investigate the effects of Vestibular Rehabilitation (VR) with and without noisy Galvanic Vestibular Stimulation (nGVS) on cognitive function in patients with aMCI. Methods: In a randomized controlled trial, twenty-two patients with aMCI were randomly assigned to two groups receiving: 1) VR for four weeks (VR group); 2) VR for four weeks with nGVS for three sessions (GVS+VR group). Outcome measures were Rey's Auditory-Verbal Learning Test (RAVLT), Corsi blocks, Visual Search (VS), and match to sample tests. Results: Mean immediate and delayed recalls of RAVLT, all of the outcomes of Corsi blocks and VS tests, and the error rate of the match to sample tests improved significantly after intervention in VR and GVS+VR groups. Between-group differences were observed for learning and delayed recalls of RAVLT (p=0.001, d=0.444 and p&lt;0.001, d=0.512 respectively), reaction times 1 and 2 in VS (p=0.007, d=0.325 and p=0.001, d=0.446 respectively), the total correct trial of Corsi blocks (p=0.026, d=0.235), and error rate of the match to sample (p=0.017, d=0.266) tests. Conclusion: The synergistic effect of VR and GVS suggested that simultaneous use of both stimulations improves verbal and visuospatial memory in aMCI patients.

The effect of a course mindfulness exercises on working memory indexes in adolescents

Introduction: Research has shown that neglecting psychological skills such as mindfulness leads to a decline in physical and psychological performance in people. Aim: The aim of this study was to investigate the effects of a course of mindfulness exercises on working memory indexes in adolescents. Method: The present study was a semi-experimental study with two experimental and control groups. The statistical population consisted of teenagers aged 14 to 18 years in the first district of Tehran city in 2022. The participants included 20 adolescents (10 girls and 10 boys) who were available, selected, and randomly divided into two 10-member mindfulness and control groups. The mindfulness group exercises lasted 20-45 minutes per session for 6 weeks. Corsi Block software was used to measure working memory indexes. Mixed analysis of variance and independent and paired t-tests were used to analyze the data. All statistical analyzes were performed with SPSS software version 21 at the P&lt;0.05 level. Results: The results for the number of correct responses showed that the main effect of stage (F=26.85, P=0.0001, η2=0.59) and the interactive effect of stage-group (F=10.87, P=0.004, η2=0.37) were significant, but the main effect of group (F=0.23, P=0.59, η2=0.01) was not significant. The results of the paired-samples t test showed that the mindfulness group showed significant progress from the pretest to the posttest (P=0.0001). Conclusion: The results of this study show the effect of mindfulness exercises on working memory indicators in adolescents. This type of intervention can be of great help to professionals in this field to improve people's cognitive and motor performance. Therefore, it is suggested to use mindfulness exercises to improve working memory and its effect on the process of cognitive decisions.

Visuospatial orientation in vestibulopathy

BACKGROUND: The vestibular system plays a critical role in maintaining the balance function and, therefore, its inputs must be integrated with the highest brain functions. Spatial memory is a cognitive process responsible for recording information about spatial environment and spatial orientation where a person can remember different locations as well as spatial relations between objects. It can be short or long term. For this reason, emerging research suggests the vestibular system can be considered as a potential window for exploring brain function beyond that of maintenance of balance.METHODS: This is a case-controlled study. Thirty-six subjects with age ranging from 20-60 years were included in the study; 18 patients with chronic vestibular hypo-function who received vestibular rehabilitation and 18 healthy controls. All study groups had full history taking of dizziness include: duration, characters, frequency, precipitating factors, reliving factors and associated symptoms, otologic and neurological examination, basic audiological evaluation, bedside vestibular evaluation and caloric testing. For visuospatial memory, Corsi block tapping test was performed.RESULTS: A statistically significant difference was found on Corsi scores between vestibular loss group and healthy individuals group. There was a statistically significant difference between vestibular loss group pre- and post-rehabilitation except for the bilateral loss group and elderly. A positive significant correlation was reported in young adults when comparing rehabilitation hours with Corsi scores.CONCLUSIONS: Our study confirmed the effect of vestibulopathy on cognition and how vestibular rehabilitation training improve visuospatial working memory in patients suffering from vestibulopathy.

NeuroMET Memory Metric: Improving accuracy and comparability with crosswalks

AbstractBackgroundThe ability to measure, track over time, and compare memory ability for people with neurodegeneration is important. However, currently, full comparability of memory test data is limited by a lack of quality assurance of memory measurements. At AAIC 2021, we presented a preliminary item bank to assess memory, composed by selecting items from legacy tests according to metrological principles through use of the Rasch model and with item equivalence based on entropy.MethodHere, we demonstrate direct comparability of measurements generated from different tests, with the new NeuroMET Memory Metric comprising 87 selected items for task difficulty from: the Corsi Block Test, Digit Span Test, Rey’s Auditory Verbal Learning Test, Word Learning List from the CERAD test battery and the Mini Mental State Examination. Data were collected from the European EMPIR NeuroMET and the SmartAge studies recruited at Charité Hospital (Healthy controls n = 92; Subjective cognitive decline n = 160; Mild Cognitive Impairment n = 50; and Alzheimer’s Disease n = 58; age range 55‐87).ResultsThe Rasch analysis showed well‐targeted items for all participants’ abilities; good fit to the measurement model, with 83 items (95%) having fit residuals within the expected range and satisfactory unidimensionality, and item reliability of 0.96. The full item bank comprising 87 short‐term memory items gave a person reliability of 0.85. Subsequently, a conversion table was created linking the raw scores from the legacy tests to the common NeuroMET Memory Metric and to individual legacy tests.ConclusionLegacy memory tests have previously proven useful in clinical practice and research, and will continue to be used, but have to date been metrologically limited. The provided conversion table, linking these legacy memory tests to a metrologically assured scale, viz., the NeuroMET memory metric, remedies this deficiency. The NeuroMET memory metric will be included in the first ever prototype of a metrological validated app used to deliver memory tests. Clinicians and researchers will be able to select sets of items to produce data, via a scoring algorithm for transforming patient responses to measures, in a common frame of reference.

Deep Learning-Based Approach for Classification Of Mental Tasks From Electroencephalogram Signals

Background and Objective: Electroencephalography (EEG) analysis is an important tool for neuroscience, brain-computer interface studies, and biomedical studies. The primary purpose of Brain-Computer Interface (BCI) studies is to establish communication between disabled individuals, other individuals, and machines with brain signals. Interpreting and classifying the brain's response during different cognitive tasks will contribute to brain-computer interface studies. Therefore, in this study, five cognitive tasks were classified from EEG signals. Material and Methods: In this study, five neuropsychological tests (Öktem Verbal Memory Processes Test, WMS-R Visual Memory Subtest, Digit Span Test, Corsi Block Test, and Stroop Test) were administered to 30 healthy individuals. The tests assess the volunteers' abilities in verbal memory, visual memory, attention, concentration, working memory, and reaction time. The EEG signals were recorded while the tests were administered to the volunteers. The tests were classified using two different deep learning algorithms, 1D Convolutional Neural Networks (CNN) and Long Short-Term Memory (LSTM), from the recorded EEG signals. Results: When the success of the tests was evaluated, classification success was achieved with an accuracy of 88.53% in the CNN deep learning algorithm and 89.80% in the LSTM deep algorithm. Precision, recall, and F1-score values for CNN were calculated at 0.88, 0.87, and 0.87, respectively, while precision, recall, and f1-score values for the LSTM network were obtained at 0.90, 0.89, and 0.89. Conclusion: Following the findings of the present study, five different cognitive tasks were able to be classified with high accuracy from EEG signals using deep learning algorithms.

여가적 게임참여수준에 따른 집단 간 인지기능 및 운동조절능력 차이

The purpose of this study was to compare cognitive and motor control skill task performance among high and low groups according to the level of participation in video game as leisure for explaining the positive aspects of participation in leisure games. Participants were recruited from right-handed male and female adults in their 20s and 30s (n=153). To evaluate cognitive function and motor control skill, a measurement program consisting of 9 cognitive tasks was used: Trail Making Test, Corsi Block Test, Tower of London, Key-mapping, shooting game performance(Grid Shot, Sphere Track), etc. Descriptive statistical analysis and normality test were conducted. The difference in cognitive task performance and motor control skill between high and low game participation groups was identified in the Mann-Whitney U analysis, a non-parameter test method, and the statistical significance level was set to .05. As a result, the high group according to the level of participation in video game showed overall higher task performance than the low group. TMT_A(p=.034), Key-mapping(default p=.039, random 2nd p=.043, random 3rd p=.039), and motor control skill tasks through gaming condition (Grid Shot p=.032, Sphere Track p=.030) were verified statistically significant differences between groups. The current study verifies the hypothesis that leisure game participation activities can increase neural plasticity of brain cognitive function and motor control skill. Also, it implies the positive aspects of game participation through significant empirical data.

Class-Based Cognitive Reinforcement (CORE) Improves Executive Functions in Preschoolers

ABSTRACT Executive functions (EFs) play a crucial role in academic performance. In the present study, we aimed to improve EFs through a group-based cognitive training. Thirty-three typically developing children (age mean: 58.80 ± 7.04 months) were recruited in a random clinical trial design in two intervention (n = 18) and active control (n = 15) groups. Emoji selection, shifting attention, day/night Stroop, Corsi block tapping tasks, and behavioral rating inventory of executive function (BRIEF) were used for assessment in three baseline, post-intervention, and 3-month follow-up sessions. The intervention group received Class-based Cognitive Remediation (COREN) and the active control group participated in a storytelling class, both in 12 sessions. The result suggests improvement in sustained attention, cognitive flexibility, inhibitory control, and working memory in intervention group. The rating scales showed improvement in executive functioning in the intervention group based on parental rating. Group-based cognitive training is beneficial to improve EFs in kindergarten.
