The purpose of the current study was to examine dual mediation effect of executive function deficiencies and adaptive cognitive emotion regulation strategies in the relation of smartphone addiction and subjective well-being and to suggest implications for adult smartphone addiction intervention programs. A self-report survey was conducted to 148 adults(71 males and 77 females) and the mediation effect was evaluated by regression analyses. Key findings are as follows. First, executive function deficiencies showed mediation effect on the relationship between smartphone addiction and adaptive cognitive emotion regulation strategies. Second, significant mediation effect of adaptive cognitive emotion regulation strategies was not found on the relationship between smartphone addiction and subjective well-being. Finally, the relation of smarphone addiction and subjective well-being was mediated by executive function deficiencies and adaptive cognitive emotion regulation strategies. These results imply that it would be helpful to train executive function and foster emotion regulation strategies to the adult smartphone addiction groups. Finally, limitations of this study and suggestions for future research of the entire adult age group were discussed.

This study examined the relationships between children's cool executive function(cool EF), hot executive function(hot EF) and self-regulation according to the developmental changes. Children aged 3-5 years (N = 104) participated in this study. The participants completed cool and hot EF tasks and teachers reported on the children's cognitive regulation, emotional regulation, and behavioral regulation by means of questionnaires. The results indicated that cool EF and hot EF had different developmental patterns according to different age groups. High levels of cool/hot EF predicted better abilities in terms of cognitive, emotional, and behavioral regulation respectively. The relationship between coo/hot EF and cognitive/behavioral regulation were moderated by age, except in the case of emotional regulation. This paper also offers a detailed discussion of results and recommendations for future studies.

The aim of this study was to investigate the effects of computer-based cognitive rehabilitation and traditional cognitive training on the working memory and executive function of patients with mild traumatic brain injury. The sample consisted of 20 patients with mild traumatic brain injury who had received rehabilitation treatment in a rehabilitation unit. The subjects were assigned to either the experimental (n = 10) or control group (n = 10). The experimental group received computer-based cognitive rehabilitation and traditional cognitive training for 60 minutes, whereas the control group received only traditional cognitive training for 60 minutes. Both the groups received their respective interventions for 60 minutes a day and 5 times per week across a period of 4 weeks. Working memory and executive function were assessed using the digit span test (forward and backward), visual memory 1 and 2 of the Motor-free Visual Perception Test-3, trail making test, and Stroop test (A and B) both before and after the intervention. The experimental group showed a significantly greater improvement in visual memory and performance on the Stroop test A than the control group. These findings suggest that computer-based cognitive rehabilitation and traditional cognitive training are more effective in promoting positive changes in the working memory and executive function of individuals with mild traumatic brain injury than traditional cognitive training.

High-performing athletes possess the ability to read the game, known as the "sports brain". However, a cognitive battery to measure such sports brain has not been developed yet. The purpose of the study, thus, is to develop a computerized cognitive test battery to measure athletes' cognitive function. Based on a systematic review, information processing speed, execution function, and spatial ability were selected as sports-related cognitive functions. Simple and choice response times test, trail-making test, Flanker test, and mental rotation task were developed. After providing manual and practice trials, main tests were executed and all primary variables were statistically processed and automatically saved. The test battery is expected to aid in the discovery and recruitment of athletes in the future after verifying the validity and reliability of this battery.

The present study investigated the related variables of cognitive function, subjective cognitive decline and cognitive training effects. The cognitive training was composed of mete-cognitive education and cognitive task performing. Twenty older adults attended for 14 weeks and were tested before and after the training. Results show that their cognitive level was related with age, self-esteem and personality traits. And subjective cognitive decline was related depression, anxiety, personality traits, self-efficacy, self-esteem and subjective age, but it does not reflect objective cognitive impairments. Their cognitive test scores were enhanced after training in MMSE, memory and executive function, and enhanced scores were related with age, subjective cognitive decline, anxiety, self-efficacy, self-esteem, subjective age and personality traits. Findings suggest one's personality and psychological state need to be considered for the effects of cognitive training.

The purpose of this paper was to analyze the differences in executive function according to type of early English learning experience. The subjects were 75 5-years-old who had immersive early English learning in language school, and daycare center. The measurement tools were stroop, DCCST, memorize numbers, pattern fluency, and maze. We conducted covariance analysis with total intelligence as the covariates. In the results, there were significant differences in attention control and cognitive flexibility, but weren't significant differences in information processing and goal setting according to type of early English learning experience. This study suggests that experience of immersive early English learning positively affected attention control and cognitive flexibility, and didn't affect information processing and goal setting.

This study conducted systematic review and meta-analysis to analyze the effectiveness of a dual-task for cognitive function in patients with MCI in Korea. A search was conducted using eight databases, and the search terms were MCI, cognition, and dual task. This study includes RCT and nonRCT published from January 2013 to July 2023. A total of 682 studies were searched, and 8 studies that fulfilled the inclusion and exclusion criteria were finally analyzed. Methodological quality was assessed with the RoB, RoBANS. The meta-analysis used CMA 4.0 ver. As a result of the analysis, the overall effect size of the dual task was medium effect size. The effect size according to the outcome variables was large for orientation and executive function, and medium effect size for global cognitive function, visuospatial function, memory, and attention. As a result of analysis according to the intervention period, the effect was greater when applied for 4 to 8 weeks, and the effect size was larger when applied for 24 to 30 sessions. This study presented clinical evidence on the effectiveness and application method of a dual-task applied to improve cognitive function in patients with MCI.

Objective : The purpose of this study was to verify the effect of virtual reality interventions (VRIs) on cognitive function in individuals with stroke through a systematic literature review and meta-analysis. Methods : We reviewed randomized controlled trials (RCTs) the last 10 years using academic databases. PubMed, MEDLINE, and CINAHL were used for international studies, and DBpia, KISS, Kyoboscholar, and e-article were used for Korean studies. For the quantitative meta-analysis, subgroups of outcomes were classified into general cognitive function (G-CF), attention and memory (A&M), and executive function (EF). Results : Nine RCTs were analyzed. The total number of participants was 271 (140 in the experimental group). The effect size (Cohen's d) was estimated using a random effects model. The effect sizes of the outcome subgroups of were as follows: small to medium for G-CF (d=0.422; 95% CI: 0.101~0.742; p=0.010), small for A&M (d=0.249; 95% CI: -0.107~0.605; p=0.170), and medium for EF (d=0.666; 95% CI: 0.136~1.195; p=0.014). Conclusion : Considering the various stimuli provided by the virtual environment and the results from available research, virtual reality should be applied to interventions for integrated cognitive functions. In addition, it would be appropriate to be used as an additional intervention to traditional cognitive rehabilitation for stroke.

The purpose of the study is to examine sports-related cognitive functions through a systematic review and to suggest effective instruments to measure the cognitive functions. The present study was conducted based on the systematic review and meta-analysis protocol-the PRISMA. Of 429 articles searched through keywords from 2008 to 2020, 45 articles that met the selection criteria were analyzed. It was revealed that athletes had better cognitive functions than non-athletes, that the higher the sports expertise was, the higher the cognitive functions, and that there were differences in cognitive functions according to the sport types. The primary cognitive functions related to sports performance summarized as executive functions (inhibition ability, cognitive flexibility), information processing speed, spatial ability, and attention. As tasks for measuring each cognitive function, a stop signal task for inhibition ability, a design flexibility task for cognitive flexibility, a simple and choice reaction time test for information processing, a mental rotation task for spatial ability, and an attention network test for attention are appropriate.

Mathematics is among the most important subjects in the middle school curriculum, yet the most hated subjects by students. The present study investigated the role of perceived executive functioning on the middle school student's mathematics achievement, after controlling for other psychological factors. Results showed that the students levels of executive functioning was predictive of their mathematics achievement test scores, even after motivational and attitude variables were controlled. The impact of the executive functioning was especially noticeable for the low achievers. On the other hand, for those whose scores were high, biological variables were the only significant predictors of their scores. The results of the present study imply that the intervention programs for improving mathematics achievement of middle school students should consider the different effect of cognitive and psychological factors on their achievements.
