The aim of this study was to examine the relationships between cybervictimization and three body-related concerns: body-esteem, self-objectification, and internalization of body ideals. The aim was also to examine these relationships not only to cybervictimization in general but also to appearance-related cybervictimization more specifically. The sample comprised 482 adolescents (233 girls and 247 boys aged 13–15; two participants did not answer the question about gender) from four Swedish schools. The results showed that victims of appearance-related cyberbullying suffered from more body-related concerns: they had a poorer view of their general appearance and of their weight. They also reported more body shame, thin-ideal internalization, and appearance-related pressure from the media. This study shows that cyberbullying that focuses on the victim's appearance is associated with several body-related concerns that have not previously been studied. A novel finding was also that body-related concerns were not related to cyberbullying in general, as has been implied in earlier research, but specifically related to cyberbullying directed at the victim's appearance. The findings suggest that there is a need to include attention to the specific relationships between appearance-related cyberbullying and body-related concerns in future prevention and intervention work. 相似文献

Children who like to read and write tend to be better at it. This association is typically interpreted as enjoyment impacting engagement in literacy activities, which boosts literacy skills. We fitted direction-of-causation models to partial data of 3690 Finnish twins aged 12. Literacy skills were rated by the twins’ teachers and literacy enjoyment by the twins themselves. A bivariate twin model showed substantial genetic influences on literacy skills (70%) and literacy enjoyment (35%). In both skills and enjoyment, shared-environmental influences explained about 20% in each. The best-fitting direction-of-causation model showed that skills impacted enjoyment, while the influence in the other direction was zero. The genetic influences on skills influenced enjoyment, likely via the skills→enjoyment path. This indicates an active gene-environment correlation: children with an aptitude for good literacy skills are more likely to enjoy reading and seek out literacy activities. To a lesser extent, it was also the shared-environmental influences on children's skills that propagated to influence children's literacy enjoyment. Environmental influences that foster children's literacy skills (e.g., families and schools), also foster children's love for reading and writing. These findings underline the importance of nurturing children's literacy skills.
Highlights
- It's known that how much children enjoy reading and writing and how good they are at it correlates ∼0.30, but causality remains unknown.
- We tested the direction of causation in 3690 twins aged 12.
- Literacy skills impacted literacy enjoyment, but not the other way around.
- Genetics influence children's literacy skills and how much they like and choose to read and write, indicating genetic niche picking.

AbstractThe tall-poppy syndrome (TPS) is a pattern of behaviour whereby people who excel in some respect are cut down to size by those around them. People are often uncomfortable with those who excel and therefore, in effect, seek to put them in their place. I argue in this article that the TPS is, in some respects, getting worse, even in the creative professions. I suggest a number of reasons why this might be so and also what societies might do about it. 相似文献

BackgroundTouch screen devices are now ubiquitous, and their usage by young children is increasing. However, the effects of these devices on young children are still unknown. Therefore, this study aimed to address the associations of touch screen device exposure with symptomatic emotional and behavioral problems and language development in children between the ages of 18 and 36 months.MethodA total of 161 primary caregivers of children between the ages of 18 and 36 months were recruited from the pediatric ward and outpatient clinic at a medical center in southern Taiwan. All caregivers were asked to fill out the Child Behavior Checklist for Ages 1½–5 (CBCL 1½–5) and a questionnaire on basic personal information and touch screen device usage, and they were also interviewed with the Communication and Language Screening Test for Birth to Three Chinese-Speaking Infant-Toddlers (CLST). Independent t-test and one-way ANOVA were used to examine the differences among the categories in the demographic variables and to characterize the touch screen device usage behaviors. Pearson’s correlation was used to analyze the relationship between language delay and the extent of touch screen device exposure. After primary univariate analysis, we used multiple regression models to examine the relationships among the effects of touch screen device usage behaviors on children's emotional and behavioral problems and language development.ResultThe children’s mean age was 25.63 months (SD = 5.35). Children who spent more time on touch screen devices were more likely to have emotional problems (β = .219, p < .010, 95 % CI: .279–1.518), anxious/depressive symptoms (β = .206, p < .050, 95 % CI: .170–1.244), somatic complaints (β = .291, p < .001, 95% CI: .455–1.462), social withdrawal symptoms (β = .194, p < .050, 95 % CI: 0.133–1.150), attention problems (β = .300, p < .001, 95 % CI: .432–1.267), and aggressive behaviors (β = .247, p < .010, 95 % CI: .967–3.983). The effects were not noted on language development (β = −.136, p < .100, 95 % CI: −2.595–.147).ConclusionYoung children who spent more time on touch screen devices were more likely to have emotional problems, anxious/depressive symptoms, somatic complaints, social withdrawal symptoms, attention problems, and aggressive behaviors, but not language delay. 相似文献

新型冠状病毒肺炎疫情下普通民众焦虑的影响因素研究 总被引:1,自引:0,他引:1
为考察新型冠状病毒肺炎疫情下普通民众焦虑情绪的影响因素,采用自陈式问卷,对新型冠状病毒肺炎疫情防控下的1050位普通民众的疫情经历、媒体信息暴露时长及性质、疫情风险感知和焦虑进行调查。结果发现新型冠状病毒肺炎疫情防控当下民众焦虑情绪的发生率为18.0%,焦虑情绪的发生率在性别、年龄、受教育程度、婚姻状况和月收入等方面没有显著的差异;疫情经历、媒体信息暴露时长、负面信息暴露和感知疫情的严重性会增加焦虑情绪产生的可能性,正面信息暴露、对疫情熟悉度和可控度的感知可以减少焦虑情绪产生的可能性。这些结果说明了疫情经历、媒体信息暴露时长和性质、疫情风险感知是疫情防控当下民众焦虑出现的重要因素。 相似文献

AbstractThere is increasing evidence that low family socioeconomic status (SES) not only is a social issue, but also is a precursor to addiction to social media and other technologies. The authors investigated the relationship between family SES, stress, impulsiveness and inhibitory control, and social media addiction among Chinese female college students. The findings revealed that in lower-SES families, increased social media addiction was associated with reduced inhibitory control and increased stress and impulsiveness. A structural equation model was used to examine the mediation model hypothesis, and the results confirmed the mediating role of no-planning impulsiveness and inhibitory control between family educational level and social media addiction among Chinese female college students. These findings demonstrate the importance of reducing impulsiveness and improving inhibitory control for preventing social media addiction in female college students of low SES. Future studies are required to confirm precursors to social media addiction, elucidate causal mechanisms, and support the explanatory model of social media addiction. 相似文献

The purpose of this study is to investigate the impacts of the duration of children’s exposure to television, the level of parental guidance during the exposure and the types of animations (realistic or unrealistic) on their task persistence. A total of ninety young children with a mean age of 60.1 months (SD = 5.89) participated in the study. The time the children spent on unsolvable puzzles was recorded as an indicator of task persistence. The children were randomly assigned to either a realistic animation group or an unrealistic animation group. Initially, the children were tested with an unsolvable puzzle as a pretest. They were given a posttest two weeks later. During the test, the realistic animation group watched a realistic animation and the unrealistic animation group watched an unrealistic animation before they were asked to work on another unsolvable puzzle. The same procedure was repeated with a follow-up test two weeks later. In the pretest, no significant difference among the independent variables emerged between the groups. Multiple regression between the posttest and the follow-up test pointed out children’s daily exposure to television as a predictor of a decrease in their task persistence. The finding places more emphasis on the duration of children’s exposure to television than parental guidance and the types of television programs. 相似文献
