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 purpose of this study was to find the influence of students' cognitive styles and cognitive levels on chemistry problem solving. 322 11th grade students were administered Group Embedded Figures Test(GEFT), Group Assesment of Logical Thinking(GALT), and chemistry problem solving task about mole and stoichiometry. Chemistry task was made of ten items, 5 items of them include misleading factor(irrelevant information). The students who are field-independent and in formal operational stage got higher scores than those who are field-dependent and in transitional stage. In 5 items which have no misleading factor GALT had significantly contributed to the regression equation, while in 5 items which have misleading factor GEFT was significant contribution to the regression equation. In two items of misleading items, students who used the irrelevant information were significantly more field dependent than those who did not use this information.

Objective : Response time plays a prominent part in research on cognitive ability and the aging effect. This study aimed to identify the impact of cognitive ability on information processing by conducting cognitive response time (CRT) using a computer program. Methods : This study was conducted in 30 normal elderly (NE) and 30 elderly with amnestic MCI (aMCI), aged 65-79 years old living in Daegu and Gyeongbuk. The results were analyzed using the statistical analysis program R 4.0.2 (University of Auckland, New Zealand). Results : In the three sub-areas of CRT, the total response time showed a significant difference depending on group or age, and the error rate showed a significant difference depending on age or group in some sub-areas. In the aMCI group, the performance of CRT significantly correlated with that of the overall cognition and memory test. Conclusion : Information processing depending on aging or cognitive ability and the differential performance of processing speed could be observed through CRT. The performance of this test was found to be significantly correlated with that of the overall cognition and memory test. Therefore, CRT could be used meaningfully as a simplified tool to predict the initial cognitive disorder of the elderly in the community.

본 연구에서는 멀티미디어 환경에서 인지부하 정도에 따라 학습 수행에 어떤 차이를 보이는지를 알아보고자 하였다. 본 연구에서는 멀티미디어 환경 학습을 함에 있어서 학습 제시 유형이 학습 수행에 영향을 미칠 것으로 보아, 같은 내용을 텍스트로 제시하는 조건, 텍스트와 나레이션으로 제시하는 조건, 애니메이션과 텍스트로 제시하는 조건에서 학습하도록 한 후 학습 수행 정도를 비교하였다. 학습 수행 정도는 학습이 끝난 후 즉시 시행하는 검사와 일 주일 후에 실시한 지연검사로 평가되었다. 그 결과 텍스트로만 제시한 조건의 학습자들이 다른 조건에 비해 즉시 검사와 지연검사 모두 더 높은 수행을 보인 것으로 나타났다. 이 결과는 멀티미디어 환경에서 인지부하를 주는 자극 제시 유형은 학습에 방해를 준다는 것을 보여주며, 이는 멀티미디어로 학습정보를 제시하는 것이 어떠한 경우에서나 늘 좋은 것이 아니라, 학습자 상황과 학습 내용을 충분히 고려해야 하는 것을 시사한다.

This study was designed to determine whether cognitive impairment was evident in patients with SLE. Also, it aimed to examine the association of cognitive impairment with other clinical variables. The subjects consisted of 20 patients with mildly active SLE and 20 healthy controls. Methods : A total of 20 SLE patients and 20 normal controls completed a computerized neuropsychological test battery using Vienna Test System. These included Cognitrone test, Continuous attention test, Corsi block tapping test, Standard progressive matrices. Also, neuro-behavioral cognitive status examination was done. The symptom severity of depression was measured with Beck Depression Inventory, Hamilton Depression Rating Scale, and current medications were documented. Disease activity was rated using the SLE diasease activity index (SLEDAI). Results : SLE patients had poorer performance than normal controls on the tests of Cognitrone, attention, nonverbal IQ and memory, independent of age, education, disease activity, steroid use and depression status. Conclusion : Cognitive dysfunction was not uncommon in ambulatory SLE patients as measured by standardized neuropsychological tests. It seemed to occur independently of various clinical variables. These findings would suggest that cognitive dysfunction in SLE may be explained by reflecting subclinical central nervous system(CNS) involvement, rather than coexisting psychological distress due to chronic illness or side effect of medication.

Mini-Mental State Examination (MMSE) and naming tests have been used clinically as screening and diagnostic tools for mild cognitive impairment and dementia. Researches in other countries have reported that residential areas would affect one's cognitive abilities. In Korean, however, there was no systematic studies on geographical influences to cognitive ability among a sample of urban/rural residents. The aim of this study was to investigate the effect of urban/rural locality of residence on cognitive tests in normal elderly Korean. Residents aged 65 years and older (N=108) were administered the K-MMSE, confrontation/generative naming tests, and medical/socio-demographic interview. When comparing the total number of correct responses between urban residents and rural residents, the performances of rural group were significantly worse than those of the urban group in K-MMSE. Based on the results, our finding suggests that a factor of residential locality should be considered to examine the function and explain the cognitive decline in rural community-dwelling elders.

This study is to investigate neuro-anatomical correlation between neuropsychological results and cerebral cortex thickness of cognitive ability in the brain MRI targeting the patients with mild cognitive impairment. It was that 78 people who were diagnosed as first Parkinson's disease followed by neuropsychological screening battery(Parkinson's disease with mild cognitive impairment: 39 people; Parkinson's disease with normal cognition: 39 people) and 32 people of normal group were selected. Correlation between mild cognitive impairment and normal cognitive impairment and correlation between neuropsychological screening battery and cerebral cortex thickness in the brain MRI were performed by independent sample t-test or Pearson correlation coefficient and then level of significance of collected data was verified in p<0.05. As a result, cerebral cortex thickness of the Parkinson's disease with mild cognitive impairment in both side precuneas and right inferiortemporal lobe had statistically significant decrease. In addition, function of visuospatial ability, verbal and visual memory was reduced in neuropsychological screening battery for cognitive assessment. Especially, there was correlation between neuropsychological screening battery of verbal and visual memory anatomical left precuneus.
