  • The study examined the longitudinal relations of preschool children's peer interaction, linguistic and cognitive abilities, and self-control, while taking into account gender differences. The study was conducted with 671 preschoolers from the $5^{th}$, $6^{th}$, and $7^{th}$ wave of the Korean Children and Youth Panel Study (KCYPS). Data were analyzed by means of basic descriptive statistics, Pearson's correlations, and structural equation modeling analysis. Bootstrapping method was also used to determine the significance of indirect effects. The analysis were conducted to find the longitudinal effects of peer interaction at the age of 4 on their self-control at the age of 6, and the mediating effects of linguistics and cognitive abilities at the age of 5 on its associations. The results indicated gender differences among the variables. According to multi-group analysis, there was a significant influence of 4 years' peer interaction on subsequent 5 years' linguistic and cognitive abilities but also on 6 years' self-control across time for boys; however, no significant direct effect of peer interaction on self-control was found for girls. Based on the findings of this study, it can be implied that it is necessary to apply different methods for boys and girls to promote self-control from the influence of peer interaction and linguistic and cognitive abilities.

  • Recent studies revealed that many animals identify individual humans. In this account, we review previous literatures on individual human recognition by wild or domestic animals and discuss the three hypotheses: "high cognitive abilities" hypothesis, "close human contact" and "pre-exposure to stimuli" hypothesis. The three hypotheses are not mutually exclusive. Close human contact hypothesis is an ultimate explanation for adaptive benefits whereas high cognitive abilities and pre-exposure to stimuli hypothesis are proximate explanations for mechanisms to perform such discriminatory behaviour. We report a case study of two bird species in a human-free habitat. Long-tailed skuas, which are known for having high cognitive abilities, exhibited the human discriminatory abilities whereas ruddy turnstones did not display such abilities toward approaching humans. This suggests that highly intelligent species may have this type of discriminatory ability so that they could learn to identify individual humans quickly by pre-exposure to stimuli, even in a human-free habitat. Here, we discuss that human recognition is more common in species with rapid learning ability and it could develop for a short period of time between an intelligent species and human.

  • This paper proposes a novel of a personalized Computer Assisted Language Learning (CALL) system based on learner's cognitive abilities related to foreign language proficiency. In this CALL system, a strategy of retrieval learning, a method of learning memory cycle, and a method of repeated learning are applied for effective vocabulary memorization. The system is designed to offer personalized learning based on cognitive abilities related to the human language process. For this, the proposed CALL system has a cognitive diagnosis module which can measure five types of cognitive abilities. The results of this diagnosis are used to create dynamic learning scenarios for personalized learning and to evaluate user performance in the learning. This system is also designed in order to have users be able to create learning word lists and to share them simply with various functions based on open APIs. Additionally, through experiments, it has shown that this system helps students to learn English vocabulary effectively and enhances their foreign language skills.

  • This study investigated institutionalized children's behavior problems depending on their cognitive abilities. Subjects were 185 institutionalized children in 15 child-welfare facilities in Seoul (132 preschooler and 153 primary schoolers; 106 boys and 79 girls). Institutionalized children's cognitive abilities were measured using the Comprehension and Picture Completion Assessment, two subsets of K-WPPSI (Park et al., 1996) Comprehension and Picture Completion Assessment belong to verbal and performance scale, respectively. Measures of behavior problems included anxiety, immaturity, social withdrawal, physical symptom, hyperactivity, and aggression. Data were analyzed with mean, standard deviation, and t-test. Results showed that institutionalized children had higher scores in Picture Completion Assessment than Comprehension Assessment. Furthermore, institutionalized children with low scores in Comprehension Assessment were higher in anxiety and social withdrawal than children with high scores in Comprehension Assessment.

  • The purpose of this study was to investigate the effects of Tetris game on the cognitive abilities of students with mental retardation. Especially, this study focused on the arrangement of figures and the task attention. To do this, 33 students with mental retardation in a middle school participated and were assigned to the two treatment group. The experimental group did the Tetris game three times a week for 4 weeks, but the control group didn't the Tetris game. The experimental group revealed more higher improvement than the control group in the arrangement of figures and the task attention. The Tetris game can be used as an educational program to improve the cognitive abilities of students with mental retardation.

  • The purpose of the present research was to study mothers' perceptions about their children' cognitive abilities and the relations between such perceptions and the children's cognitive level. The subjects of this study were 60 children (mean age: 6 years 1 month: age range = 5;8 to 6;7) and their mothers. Each child responded to 18 tasks drawn from the Kodae-Binet IQ test. Subsequently, the mothers were asked 4 questions: an estimate of her child's success or failure on the tasks, a rating of the certainty of her judgment, an estimate of the age of mastery on each task both for her owr child and children in general. The data of the present study were analyzed with the 3-way ANOVA (sex x birth order x mother's education level), t-test, and Pearson correlation coefficient. Significant differences were found in (1) mothers' accuracy of their children's cognitive abilities according to children's birth order, (2) mothers' accuracy, overestimation, and certainty according to the level of difficulty of each task, and (3) mothers' estimate of age at mastery according to the level of each task. Furthermore, there were positive correlations between accurate predictions by the mother and correct answers by the child and between overestimations by the mother and correct answers by the child.

  • Autism (ASD) is a mental disorder characterized by a pronounced deficit in personal, social, speech, and other aspects of development and communication skills. Since autism is a complex developmental disorder that requires a lot of effort to recognize, this research was conducted to develop an interactive data Acquisition System and detect the first signs of ASD in children. The proposed system presents several variants of the tasks in an entertaining form, using hand tracking. Hand tracking is used to attract children's attention and interest them more to achieve more accurate results. The creation of the system is based on such libraries as OpenCV, PyGame, TensorFlow, and Mediapipe. The ultimate goal of the paper is to obtain data on the disease of autism in children for use in further diagnosis by medical experts.
