The Cognitive Social Network in Dreams: Transitivity,Assortativity, and Giant Component Proportion Are Monotonic

For five individuals, a social network was constructed from a series of his or her dreams. Three important network measures were calculated for each network: transitivity, assortativity, and giant component proportion. These were monotonically related; over the five networks as transitivity increased, assortativity increased and giant component proportion decreased. The relations indicate that characters appear in dreams systematically. Systematicity likely arises from the dreamer's memory of people and their relations, which is from the dreamer's cognitive social network. But the dream social network is not a copy of the cognitive social network. Waking life social networks tend to have positive assortativity; that is, people tend to be connected to others with similar connectivity. Instead, in our sample of dream social networks assortativity is more often negative or near 0, as in online social networks. We show that if characters appear via a random walk, negative assortativity can result, particularly if the random walk is biased as suggested by remote associations.     

Your own face is no more precious than others’: Evidence from the simultaneous–sequential paradigm

In the present study, we tested the dominant notion that the processing of familiar faces takes place in an automatic, capacity-unlimited manner. To do so, we had participants perform the task of detecting their own face among others’ nonfamiliar faces. Importantly, either all of the search stimuli were presented simultaneously or two different subsets of the stimuli were presented sequentially. The results showed that the search performance benefited from sequential presentation, indicating that detecting one’s own face depends on a capacity-limited process. A similar pattern of results was found when participants searched for someone else’s face, although there was a decline in the overall performance. These findings suggest that the processes of detecting familiar and unfamiliar faces suffer from the capacity limit of visual perception to similar extents, challenging the notion of the automaticity of familiar-face processing.     

Effects of Parental Psychological Control on Child’s School Life: Mobile Phone Dependency as Mediator

Ecological view of human development calls for an investigation of multiple contexts surrounding children. In South Korea, traditional Confucianism and recent technological advancements serve as influential social and cultural contexts that affect parent–child relations and child development. High levels of parental control and strong emphasis on academic achievement have long been distinctive features of Korean parenting practices, which are attributable to Confucian values. Additionally, Korean children’s mobile phone dependency (MPD) has become a growing concern, as South Korea developed as an IT powerhouse. Combined, these contexts resulted in high parental control of children’s mobile phone use, so that such electronic devices would not hinder learning and achievement. Effects of high parental control on children’s MPD and their school life, however, have yet to be discovered. We hypothesized, that, unlike parents’ intentions, psychological control is more likely to increase MPD and disrupt school life. To examine this research model, we made use of the first and third wave data from Korea Children and Youth Panel Survey. Participants were 2378 children (52.2 % boys) of the same age of 10 in the first wave. After multiple imputation for missing values, hierarchical logistic regression followed to examine the mediational model. The results verified the hypothesized model, showing significant adverse influence of psychological control on MPD, self-regulated learning and school adjustment. MPD fully mediated the effect of psychological control on self-regulations, while partially mediating the effects on school adjustment. Implications for Korean parents with regard to supporting children’s psychological autonomy was discussed.     

The Moderating Effects of Age on the Relationships of Self‐Compassion,Self‐Esteem,and Mental Health

This study investigated the interactive effects of self‐compassion, self‐esteem, and age on mental health. Numerous previous studies have found that self‐compassion has a significant positive association with well‐being but most of these studies were conducted with young adults represented by college students. This study extended the previous findings by comparing its distinctive functions in different age groups. A total of 1,813 adults whose age ranged from twenties to fifties (M = 39.28 years, SD = 11.27) completed a questionnaire measuring self‐compassion, self‐esteem, subjective well‐being, and depression. The results of hierarchical regression analysis indicated that the positive relationship between self‐compassion and subjective well‐being was rendered stronger with older adults. In addition, self‐compassion moderated the relationship between self‐esteem and depression regardless of age. These results imply that self‐compassion may be complimentary to self‐esteem in improving mental health, especially for older adults.     

Impact of School Psychological Environment Variables on Happiness of Korean Youths

Abstract: This study analyzed the structural relationships between school‐related psychological variables (teacher support, learning flow, friendship) and the happiness of Korean youths, and compared structural equation models for middle and high schools. Questionnaire data were collected from students in middle and high schools in 10 cities and provinces of Korea. The final data set from 870 students was analyzed with Amos 20.0. Goodness of fit indices for the hypothetical model were good, and all paths were significant. That is, a model incorporating indirect and direct impact of school‐related psychological environment variables, such as teacher support, learning flow, and friendship, on the happiness of Korean youths is valid. Second, structural equation models for middle and high schools demonstrated significant differences. Therefore, different types of assistance are needed to increase the happiness of students in middle schools and high schools.     

Overlap and Uniqueness: Linguistic Componential Traits Contributing to Expressive Skills in English as a Foreign Language

This study identified robust predictors of expressive skills in academic English as a foreign language. The participants were 92 Korean-speaking learners of English. The field test of the Pearson Test of English Academic was used as a secondary data analysis. Four communicative skills (reading, writing, listening, and speaking) and six enabling linguistic traits (written discourse, oral fluency, grammar, pronunciation, spelling, and vocabulary) were analyzed using writing and speaking skills as dependent variables. The greatest overlapping variance was found in the relationship between reading and writing. When listening and speaking skills were controlled, the unique variance accounted by reading in the prediction of writing became marginal. The results of this study demonstrated that L2 oral language skills became increasingly important to L2 writing outcomes as language proficiency improved over time.     

Resilience: A Meta‐Analytic Approach

This study investigated the relationship between psychological resilience and its relevant variables by using a meta‐analytic method. The results indicated that the largest effect on resilience was found to stem from the protective factors, a medium effect from risk factors, and the smallest effect from demographic factors.     

Teaching Engineering Ethics using BLOCKS Game

The aim of this study was to investigate the use of a newly developed design game called BLOCKS to stimulate awareness of ethical responsibilities amongst engineering students. The design game was played by seventeen teams of chemical engineering students, with each team having to arrange pieces of colored paper to produce two letters each. Before the end of the game, additional constraints were introduced to the teams such that they faced similar ambiguity in the technical facts that the engineers involved in the Challenger disaster had faced prior to the space shuttle launch. At this stage, the teams had to decide whether to continue with their original design or to develop alternative solutions. After the teams had made their decisions, a video of the Challenger explosion was shown followed by a post-game discussion. The students’ opinion on five Statements on ethics was tracked via a Five-Item Likert survey which was administered three times, before and after the ethical scenario was introduced, and after the video and post-game discussion. The results from this study indicated that the combination of the game and the real-life incident from the video had generally strengthened the students’ opinions of the Statements.     

The Emergence of Student Creativity in Classroom Settings: A Case Study of Elementary Schools in Korea

This research explores the emergence of student creativity in classroom settings, specifically within two content areas: science and social studies. Fourteen classrooms in three elementary schools in Korea were observed, and the teachers and students were interviewed. The three types of student creativity emerging in the teaching and learning process found in this research were: (a) heuristic creativity when the students express their thoughts about a new concept based on their experience, (b) interpretive creativity when the students explain the meaning of materials based on students' knowledge, and (c) integrative creativity when students generate new solutions or make new products based on their internalized knowledge. The study results will challenge teachers to find instances of student creativity in their teaching and learning situations and to facilitate student creativity when the students interpret data or materials related to the contents of the curriculum.     

Depression Moderates the Relationship between Body Image and Health-Related Quality of Life in Adolescent Girls

Body image can predict health-related quality of life (HRQoL) in adolescent girls through self-esteem and psychological well-being. Additionally, depression is a significant predictor of adolescents’ HRQoL and is associated with body image. Therefore, we investigated whether the relationship between body image and HRQoL in adolescent girls is moderated by depression. In this cross-sectional study, adolescent girls’ body image, depression, and HRQoL (n?=?385, age: 12–15 years) were measured through self-report questionnaires. Multiple regression and simple slope analyses were conducted to examine the moderating effect of depression. Body image was positively correlated with HRQoL, whereas depression was negatively correlated with body image and HRQoL. Body image, depression, and their interaction explained 44.9% of the variance in HRQoL. Simple slope analysis showed that a more positive body image was associated with higher HRQoL among adolescent girls without depressive symptoms, but was not significantly related to HRQoL for adolescents with depressive symptoms. The moderating effect of depression was confirmed. In conclusion, screening for depression is recommended for adolescent girls prior to implementing body image interventions in schools and the community that are aimed at improving HRQoL. Furthermore, health care providers in schools and the community should provide psychological support for depression along with body image interventions to improve the HRQoL of girls in schools and the community. In particular, for girls with depressive symptoms, depression management should be conducted beforehand.
