The aim of the current study was to investigate worry about terror as a mediating variable, with the exogenous variables being media viewing, differentiation of self, and trait anxiety, and the endogenous variables being somatic symptoms and perceptions of security‐related stress. Participants were divided into two groups by age/academic level: 248 high school students and 191 university students. A pathway correlation model was used to investigate worry about terror as a mediating variable. The central finding was that worry about terror was a significant mediating variable in the relationship between the extent of media viewing following terror events and the level of perception of security‐related stress. That is, young people who said they worried a lot reported a high level of stress relating to the terror events they saw covered in the media. In addition, trait anxiety was found to have an effect on stress perception only via the level of worry about terror. This means that high levels of stress are not experienced by all highly trait‐anxious people, but only by those who suffer from higher levels of worry about terror.  相似文献

The author's purpose in this study was to test 4 hypotheses that proposed different paths for the influences of children's television viewing on their academic achievement. Data were drawn from the 1997 Child Development Supplement (CDS) to the Panel Study of Income Dynamics (PSID). The population for this study included 1,203 children between the ages of 6 and 13 years from the CDS-PSID data set. The author used structural equation modeling to test pathways from children's television viewing to their academic achievement. The author assumed that children's television viewing hindered their academic achievement by reducing certain traits that related to academic achievement. Results showed that 3 hypothetical models fit the data—the time-displacement hypothesis, the mental effort-passivity hypothesis, and the attention-arousal hypothesis. A 4th hypothetical model, the learning-information hypothesis, which proposed that children's television viewing practices stimulate their academic achievement, was not supported. In sum, children who watched more television tended to spend less time doing homework, studying, and reading for leisure. In addition, their behaviors became more impulsive, which resulted in an eventual decrease in their academic achievement.  相似文献

Although previous research showed that the thin ideal provided by the media affects body image and eating behaviour in young children, less is known about specific media contents that are related to body image and eating behaviour. This study tested the associations between watching soaps and music television and body dissatisfaction and restrained eating directly, and indirectly through thin ideal internalisation. We conducted a survey in class, in which 245 girls (aged 7–9) completed scales on their television watching behaviour, thin ideal internalisation, body dissatisfaction and restrained eating. Additionally, height and weight were measured. Watching soaps and music television often was associated with higher thin ideal internalisation, which in turn was associated with higher body dissatisfaction and restrained eating. Furthermore, a direct association between watching soaps and music television and restrained eating was found. If watching other types of children's programmes or maternal encouragement to be thin were included in the models, watching soaps and music television remained an important factor, especially with regard to restrained eating. Therefore, our results suggest that if young girls watch soaps and music television often, this is related to higher restrained eating and body dissatisfaction, directly or indirectly, through higher thin ideal internalisation.  相似文献

The study aimed to investigate strategies and ethical implications of food advertising in South African television. The sample included 343 food advertisements recorded over two weeks and 224 hours from two major South African TV channels. Results indicate 45 products of food advertisements. Fast food, restaurant and convenience food type had the highest number of products (17), followed by “beverage, drink and juice” (6), and “candy and sweets” group (6). Conceptual consumption (people are as interested in consuming ideas, information, and concepts as they are physically consuming things) was used as the main strategy (76.2%) for advertising food, while only 7% focused on physical consumption (fiber, energy and vitality). The majority of food advertisement used human models (78.5%), adults only (38%) and about half used both sexes. White models were used twice as often as Black models. Other advertisement strategies included claims to having fun (majority), being perceived of a higher status, acquiring a superior of products and adding social worth to the quality of person who consume the products. A few claims related to the physical benefit to the consumer, such as high fibre, whole grain, and weight loss.  相似文献

Summary

Prosecution of crimes involving child victims and witnesses is particularly difficult because of the age of the children involved. Facing the alleged offender in court and the experience itself of testifying in an open court with dozens of onlookers are acutely difficult. The effect on children may be traumatic, with the potential to produce substantial psychological and emotional harm. Various court procedures have been implemented in the United States in an effort to minimize these effects. Court procedures can include erecting screens to shield the child victim or witness, presenting videotaped testimony, or testifying via one-way or two-way closed-circuit television. Closed-circuit television (CCTV) testimony, which is especially controversial, involves both legal issues surrounding the constitutionality of such testimony and social issues regarding the effectiveness of closed-circuit television testimony. Substantial variation across states in provisions for closed-circuit television testimony for child witnesses is problematic. Consideration is given to how social science research directly influenced the Supreme Court's decision in Maryland v. Craig(1990), and the current state of research regarding use of CCTV and court outcomes. Some research suggests a pro-defense bias when CCTV is used.  相似文献

Participants' eye movements were monitored in two scene viewing experiments that manipulated the task-relevance of scene stimuli and their availability for extrafoveal processing. In both experiments, participants viewed arrays containing eight scenes drawn from two categories. The arrays of scenes were either viewed freely (Free Viewing) or in a gaze-contingent viewing mode where extrafoveal preview of the scenes was restricted (No Preview). In Experiment 1a, participants memorized the scenes from one category that was designated as relevant, and in Experiment 1b, participants chose their preferred scene from within the relevant category. We examined first fixations on scenes from the relevant category compared to the irrelevant category (Experiments 1a and 1b), and those on the chosen scene compared to other scenes not chosen within the relevant category (Experiment 1b). A survival analysis was used to estimate the first discernible influence of the task-relevance on the distribution of first-fixation durations. In the free viewing condition in Experiment 1a, the influence of task relevance occurred as early as 81 ms from the start of fixation. In contrast, the corresponding value in the no preview condition was 254 ms, demonstrating the crucial role of extrafoveal processing in enabling direct control of fixation durations in scene viewing. First fixation durations were also influenced by whether or not the scene was eventually chosen (Experiment 1b), but this effect occurred later and affected fewer fixations than the effect of scene category, indicating that the time course of scene processing is an important variable mediating direct control of fixation durations.  相似文献

Beginning with a brief review of issues regarding the effects of television on viewers in Japan, this paper examines how foreign programming and features relating to other countries are utilized on terrestrial television, the most influential of the mass media today. Foreign cultures are introduced either through importation of programs from abroad or through indigenous programs dealing with such topics. An overview of the changing role of imported programs emphasizes comparison of the public and commercial networks. News reporting and commercials are highlighted in a discussion of the treatment of foreign cultures in indigenous programs. Survey results show that Japanese people are favorably disposed toward foreign program imports, suggesting that the major reason for the failure of imported programs to flourish in Japan is the strong competition offered by domestic productions, not xenophobic attitudes on the part of viewers. I also consider the distinguishing characteristics of television and the cinema in order to explain the popularity of films as opposed to television dramas from abroad. In conclusion, studies that examine the effects of television on viewers' perceptions of foreign cultures are presented to suggest the importance of analyzing images of foreign cultures as depicted in programs that are domestically produced, rather than analyzing those that are imported.  相似文献
