This study investigated the harmonic preference of children and adolescents depending on age and musical training. A total of 684 primary and secondary school students participated in this study. For this study, a four-measure melody was composed and constructed in four levels of harmonic complexity, determined by the rate of nonharmonic notes used and immediacy of harmonic resolution. Participants rated the degree of their perceived complexity and their preferences after listening to each musical stimulus. Ratings from the participants were analyzed in terms of the effect of age and the length of musical training. The results showed that younger students demonstrated little to no change in their preference regardless of the complexity level. Middle and high school students showed significantly decreased preference with increased harmonic complexity. High school students with more musical instrument training perceived changes in harmonic complexity more sensitively and showd higher level of optimal complexity. Younger students was affected by musical training relatively less than older students. This study presents the baseline data to be considered when determining the appropriate level of harmonic complexity for music appreciation of young population.

The purpose of the present study was to investigate empirically the relationship among self-image, depression, anxiety, and social sensitivity in adolescents. 1602 normal adolescents(697 males and 905 females) responded to self report scales-Offer Self-Image Questionnaire-Revised, 3 subscales of Symptom Checklist-90-Revised. The data were analyzed with ANOVA and LISREL to examine the effect of self-image on depression, anxiety, and social sensitivity, and to test the relationship among the above 4 variables. Adolescents with low self-image showed significantly higher scores in the scales of depression, anxiety, and social sensitivity than did adolescents with high self-image. The result of LISREL showed that the low self-image leads to the emotional state of depression and anxiety, and those of depression and anxiety lead to the increase of social sensitivity, suggesting that self-image has a direct effect on depression and anxiety, and has a direct effect on social sensitivity in adolescent. These results were discussed in terms of implications for the prevention and treatment of adolescent social phobia.

The goal of this study was to investigate how daily experiences of schoolwork and leisure activities explained cultural differences in levels of adolescent depression. A combined sample of 58 high school seniors in Korea and 62 high school seniors in the United States reported time use patterns and affect states in daily activities and levels of depression. The time use pattern in daily independent study during class hours and in active leisure activities significantly explained cultural differences in levels of depression. Affect states in all schoolwork activities and passive leisure activities also significantly explained cultural differences in levels of depression. These findings suggest that Korean adolescents' experience of 'exam hell', particularly the lack of active leisure activities and more negative emotional experiences of daily activities are partly responsible for their higher depression relative to American counterparts.

This study investigates the factors associated with adolescent females' sexual behavior. Results from 390 adolescent females reveal that dating atmosphere was the strongest and the most influential risk factor predicting adolescent females sexual behavior, which has been a neglected variable in the research of adolescent sexual behavior. Age and similarity of sexual attitude with her dating partner, in addition to the dating experience had very significant impacts on highly sexually experienced adolescent females' sexual behavior. Adolescent females with low sexual experiences were significantly affected by similarity of sexual attitude with dating partner, siblings, and peers, her own attitude, age, and dating atmosphere. The findings from this study also indicate that parental supervision, dating atmosphere, respondent's sexual attitude, love for partner, and communication with parents on sexual issues were significant factors for determining adolescent females' sexual involvement.

It has long been accepted that test anxiety is developed by parent-child relationship. The purpose of this study was to investigate the parent influence on student's test anxiety. The Korean Form of Test Anxiety Inventory(TAI-K) and the Parent Attitude Scale were used. 481 primary school-and 500 high school students were participated in the study. The results were as follows ; 1) The parental factor identified as 'rejecting' was positively correlated with students' test anxiety, while the parental factor identified as 'rearing as self-controlled being' was negatively correlated. 2) The students who identified their parents as 'being achievement-oriented' reported significantly higher test anxiety than those who identified their parents as 'accepting'. Many studies also report that high test anxiety interferes with student's performance. Therefore, parents should accept and understand their children in order to alleviate test.

In this study, the autoregressive cross-lagged model was applied to verify the longitudinal correlation between the three factors and the pattern of changes over time in the mother's cultural adaptation type, the multicultural acceptability of multicultural adolescents, and national identity. For the study, longitudinal data from the 2nd, 4th, 6th, and 8th years of the MAPS tracked from the 5th grade of elementary school to the 2nd grade of high school were used for analysis. As a result of the analysis, all four types of mother's acculturation were analyzed to have a significant longitudinal effect over time. The four types of mothers' cultural adaptation were analyzed to have a longitudinal mediating effect on the relationship between the national identity of multicultural youth. Based on these analysis results, it is necessary to provide a continuous acculturation support program. In order to have a sense of belonging and solidarity with the country, it was suggested that education to increase multicultural receptivity should be carried out in parallel.

The purpose of this study is to investigate the effect of school library reading classes on the convergence literacy of adolescents based on the convergence reading education model. To achieve this, elements of convergence education for future-oriented competence were derived from the level of reading education based on previous studies and literature, and the effectiveness of education was measured by conducting a convergence literacy test targeting 50 general high school students. In this study, reading classes and tests were conducted over 12 sessions from April 2022 to November 2022, and the study participants were divided into two groups, and convergence reading education and self-reading education were applied respectively. The analysis results of this study are as follows. First, It was verified that there was a significant difference in the promotion of convergent literacy of adolescents according to the method of reading education. Second, it was verified that convergence reading education had a significant effect on convergence literacy of adolescents such as convergence, creativity, self-direction and communication ability. Third, as a result of verifying whether learning motivation plays a mediating role in convergence reading education influencing convergent literacy, learning motivation played a partial mediating role and had an indirect effect on creativity, self-direction, and communication ability between convergence reading education and convergence literacy, but showed no significant mediating effect on convergence ability.
