The Determination of Normal Extravert-Introvert Interest Differences

The authors conducted a survey of 1,758 elementary school children (6-14 years old) from December 2001, to March 2002, in 3 Chinese cities with different levels of television advertising. The authors used D. R. John's (1999) model of consumer socialization as the theoretical framework for their study. More than half of the children whom the authors interviewed were able to understand that television stations broadcast commercials to earn money. Their understanding of the purposes of television commercials and the persuasive intention of television commercials developed with age. The authors examined the influence of gender, level of advertising, and level of television viewing on children's understanding of television advertising by using 3-way factorial models.     

Reducing Children's Susceptibility to Commercials: Mechanisms of Factual and Evaluative Advertising Interventions

The aim of this study was to investigate how factual and evaluative interventions modify the effects of television advertising among children in early and middle childhood. First, a conceptual model of advertising intervention was developed, and then this model was experimentally tested drawing on a sample of 5- to 10-year-old children (N = 206). Structural equation modeling analysis confirmed that factual intervention reduced children's susceptibility to commercials by stimulating their advertising knowledge and skepticism, and evaluative intervention reduced children's susceptibility by influencing their attitudes toward commercials negatively. For children older than 6, both factual and evaluative interventions were successful in modifying the effects of advertising, whereas the younger children had difficulty processing any type of intervention.     

Female attractiveness and eating disorders: Do children's television commercials play a role?

The differential rate of eating disorders in males and females has been partially attributed to gender socialization. Media influences, even in children's programming, may contribute to the greater emphasis on physical attractiveness for girls compared to boys. Commercials from Saturday morning cartoon programming were analyzed for the number of male/female main and supporting characters, sex of narrator, sex of intended consumer, and appearance enhancement of person, doll, or animal. A majority of the commercials (60.6%) were for food products. Chi-square comparisons revealed significantly more male than female main characters and narrators in these commercials. Of those commercials (13.8%) scored for appearance enhancement, all male/female chi-square comparisons were significant with more female supporting characters, female main characters, female narrators, and female consumers. With the combined emphases on food and, for girls, on appearance, support for possible influences of commercials in eating disorders is noted.     

The effects of TV commercials using less thin models on young women's mood, body image and actual food intake

This study experimentally tested the effects of exposure to television commercials using less thin models on mood, body focused anxiety and food intake, as compared to the effects of commercials using thin models. In a naturalistic setting, 110 young women were exposed to a neutral movie, interrupted by two commercial breaks. The commercial breaks contained real commercials using either less thin (n = 32) or thin models (n = 39), or neutral commercials (n = 39). During watching television, participants could freely eat snack food. Further, their mood and body focused anxiety was assessed. ANOVAs revealed no effects on body focused anxiety, but women reported a more negative mood and ate less after exposure to commercials using less thin models than after exposure to commercials using thin models. These results imply that using less thin models in commercials explicitly referring to the thin ideal does not make women feel better.     

The expectation of guilt and resistance to temptation

Children's expectations about the emotions that surround a moral transgression were examined. In experiment 1, children aged 4-6 years and 8-9 years listened to a story about a child who resisted but then yielded to the temptation to take a sweet without permission. In line with earlier findings (Nunner-Winkler and Sodian, 1988), older children were more likely than younger children to expect the wrongdoer to feel pleased at resisting, but to feel bad after yielding to, temptation. In experiment 2, the relation between expectations of emotion and actual resistance to temptation was studied. Children aged 5-6 years again made judgements about a story character who eventually yielded to temptation. Their own resistance to temptation was assessed by means of a cheating task: children were given an opportunity to cheat by peeking during the experimenter's absence. Children who did not peek were more likely to attribute morally oriented feelings to the story protagonist. The results suggest that children who readily anticipate the emotional consequences of wrongdoing are more likely to resist the temptation to transgress.     

The effectiveness of parental communication in modifying the relation between food advertising and children's consumption behaviour

The aim of this study was to examine the effectiveness of various types of parental communication in modifying children's responses to television food advertising. In a combined diary‐survey study among 234 parents of 4‐ to 12‐year‐old children, I investigated how different styles of advertising mediation (active vs. restrictive) and consumer communication (concept‐oriented vs. socio‐oriented) moderated the relation between children's advertising exposure and their consumption of advertised energy‐dense food products. Interaction analysis in regression showed that active advertising mediation (i.e. explaining the purpose and nature of advertising), and socio‐oriented consumer communication (i.e. emphasizing control and restrictions) significantly reduced the impact of advertising on children's food consumption. Parental restrictions of advertising exposure were only effective among younger children (<8). These results suggest that critical discussion about advertising and rule making about consumption are most effective in countering the impact of food advertising.     

Exposure to media and theory-of-mind development in preschoolers

Exposure to different forms of narrative media may influence children's development of theory-of-mind. Because engagement with fictional narratives provides one with information about the social world, and possibly draws upon theory-of-mind processes during comprehension, exposure to storybooks, movies, and television may influence theory-of-mind development. We examined 4–6 year-olds’ inferred exposure to children's literature, television, and film, using an objective measure that controls for socially desirable responding. Theory-of-mind was assessed using a battery of five tasks. Controlling for age, gender, vocabulary, and parental income, inferred exposure to children's storybooks predicted theory-of-mind abilities. Inferred exposure to children's movies also predicted theory-of-mind development, but inferred exposure to children's television did not.     

Exploring Pathways From Television Viewing to Academic Achievement in School Age Children

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.     

Children's and adults' recall of children's news stories in both print and audio‐visual presentation modalities

Research into adults' recall from different presentation modalities has demonstrated a recall advantage for print over television yet recent research indicates that children remember television news better than print news. An experiment was conducted by comparing children's and adults' recall of children's news stories presented in two different modalities, television and print, in order to establish whether children's recall advantage for television is dependent on their age or level of reading proficiency. A sample of 40 adults, 40 13‐year‐olds and 40 11‐year‐olds were presented with children's news stories, either in their original televised form or in a print version. All participants were aware they would be tested for recall. The results of the cued recall test indicated that children from both age groups learned more from the television news than from the print versions, regardless of age or reading proficiency and that adults remembered equal amounts from both presentation modalities. For the 11‐year‐olds the advantage of television was only found for information that had been accompanied by redundant pictures in the televised version, providing support for the dual‐coding hypothesis. For 13‐year‐olds the recall of television was not dependent on the addition of redundant visual information. Viewers and readers were found to invest the same amounts of mental effort, but reported levels of invested mental effort were found to be dependent on age and level of reading proficiency.

Longitudinal Effects of Television on Children's Leisure-Time Reading A Test of Three Explanatory Models

Using a sample of 1,050 Dutch elementary schoolchildren who were in Grades 2 and 4 at the outset of the research, this study investigated (a) the longitudinal effects of television viewing on the frequency with which children read books and comic books at home, and (b) the causal mechanisms that underlie television's effects on leisure-time reading. The children were surveyed three times, at 1-year intervals. Structural equations analysis suggested that television viewing reduced children's comic book reading only in the period from Year 2 to Year 3. Book reading, however, was found to be reduced by television viewing over both measurement periods. The data suggest that two causal mechanisms underlie television's reductive effect on children's book reading: (a) a television-induced deterioration of attitudes toward book reading, and (b) a television-induced deterioration of children's ability to concentrate on reading.     

Exposure to slim images in mass media: television commercials as reminders of restriction in restrained eaters

OBJECTIVE: The aim of the present study was to explore the effects of exposure to slim images and diet-related products in commercials on actual food intake in relation to dietary restraint. DESIGN: An experimental design was used, in which food intake was measured in 124 female students who watched either a sad or a neutral movie on television, which was interrupted by either commercials featuring slim models and diet products, or neutral commercials. Subsequently, participants filled out questionnaires on dietary restraint and any tendency toward overeating. MAIN OUTCOME VARIABLE: Intake of snack food while watching television. RESULTS: It was found that highly restrained students exposed to commercials with slim models and diet-related products ate less food, whereas less restrained eaters ate slightly more after seeing these commercials. CONCLUSION: The findings suggest that restrained eaters confronted with diet products and slim images when watching television will be reminded of their restricted eating behavior and eat less. The present study provides support for the reinhibition theory of slim media images.     

Predicting children's media use in the USA: Differences in cross‐sectional and longitudinal analysis

The purpose of this paper is to examine the predictors of children's media use in the USA, comparing cross‐sectional and longitudinal analyses. Data come from Waves 1 and 2 of the Child Development Supplement (CDS‐I; CDS‐II), a nationally representative sample of American children aged 0–12 in 1997 and 5–18 in 2002. Twenty‐four hour time use diaries are used to assess children's time spent with media (television, video games, computers, and reading). Predictors examined include socio‐demographics, neighbourhood quality, family factors, and other media use. Ordinary least square (OLS) multiple regressions were performed by three age groups (preschoolers, early school age, and preadolescence). The findings suggest that neighbourhood quality, parental limits and family conflict are significant predictors of children's media use within time or over time, but the significance depends on the type of media and child's developmental stage. In addition, children's television viewing and reading habits are formed early in life and reinforced over time. This study is among the first to provide empirical evidence for the effect of early contextual factors on the life course of children's media use from a developmental perspective.     

Children's Memory for News: A Comparison of Three Presentation Media

A study was conducted to compare children's learning of news information from television versus from audio-only or printed text presentations of the same narrative content. Although previous research among adults has yielded contradictory findings, research with children has found that they consistently remember news better from television than from print. The experiment extended this work by comparing children's recall of news information from different presentation media and investigating whether the effectiveness of the different media is dependent on expectation of a memory test and the children's reading proficiency. A sample of 166 male and female 10- and 11-year-olds was presented with a sequence of news stories taken from a children's news program either in their original televised form, in soundtrack only, or in a print version. Half of the children were led to expect a memory test, and half were not. The results of the cued recall test indicated that children learned more from television news than from the print and audio versions, regardless of their reading proficiency. The advantage of television was found only for information that had been accompanied by semantically redundant pictures in the televised version, providing support for the dual-coding hypothesis     

HOW AND WHAT DO CHILDREN LEARN FROM TELEVISION?

The paper provides a review and critical synthesis of research and theory dealing with the processes involved in children's learning from television. It asks how and what children learn from television, and at what ages television is a more or less powerful teacher. The focus is on assessing evidence that television can play a positive teaching role. It is suggested that a threshold model may be more appropriate than a linear model for evaluating television's impact on viewers. It is concluded that television can play a positive role in children's learning, but given typical North American media diets and current television content, the opposite has been true for most children.     

CHILDREN'S PERSON PERCEPTION: THE GENERALIZATION FROM TELEVISION PEOPLE TO REAL PEOPLE

This study investigated children's perceptions of television people and the extent to which these perceptions are generalized to impressions of peers. Elementary school children (W=172) completed questionnaires measuring viewing, knowledge of, identification with, and the perceived reality of television characters, and ratings of peers on 11 traits (e.g., funny, attractive, kind, nice). Two criterion variables were studied: children's mean rating of peers on each of the traits and the variance in the ratings of peers on each trait. Multiple regression analyses (controlling for grade and sex) revealed that: (1) identification with television characters was a significant predictor of the mean evaluation of peers on the traits; (2) television viewing was a significant predictor of the variance in children's ratings of peers; and (3) the relationship between television viewing and the variance in trait ratings was lower for attributes found in past studies to be suggested by television presentations. Implications of these findings for the traditional concern that television standardizes perceptions of people through stereotyping are considered.     

Gender Representation in Television Commercials: Updating an Update

Sex Roles - We replicated the studies of O'Donnell and O'Donnell (1978) and Lovdal (1989) to analyze trends in gender representation in television commercials. A total of 757 commercials in...     

Can Toddlers Learn Vocabulary from Television? An Experimental Approach

This study was inspired by the rise in television targeting toddlers and preverbal infants (e.g., Teletubbies, Baby Mozart). Overall, we investigated if very young children who are in the early stages of language acquisition can learn vocabulary quickly (fast map) from television programs. Using a fast mapping paradigm, this study examined a group (n = 48) of toddlers (15–24 months) and their ability to learn novel words. Utilizing a repeated measures design, we compared children's ability to learn various novel words in 5 different conditions. These included the presentation and identification of a novel word by an adult speaker via live presentation when the toddler was attending (i.e., joint reference), an adult via live presentation when the toddler was not attending, an adult speaker on television, and an edited clip from a children's television program (Teletubbies). Overall, the toddlers were most successful in learning novel words in the joint reference condition. They were significantly less successful in the children's program condition. Furthermore, there was a significant interaction between age and condition on children's performance. Both younger (15–21 months) and older (22–24 months) participants identified the target objects when they were taught the novel word by an adult speaker; however, it appeared that children under the age of 22 months did not identify the target item when they were taught the novel word via the television program.     

Children's Judgments of Certainty and Uncertainty on a Problem Where the Possible Solutions Differ in Likelihood

In this study the author examined why children and adults think they need to eat. Preschoolers through adults were provided with physiological, social, psychological, and routine causes for eating breakfast, lunch, snack, and dinner, and were asked to either agree or disagree with the causal responses provided. A 4 Reason × 4 Meal repeated measures analysis of variance revealed significant main effects for meals and reasons, as well as significant Meal × Reason and Meal × Reason × Grade interactions. The effect sizes ranged from 0.1 to 0.7. Across all age groups, participants acknowledged physiological needs and desires (fulfilling hunger and needs to stay healthy) and routine (e.g., it is dinner time) as the primary causes for eating breakfast, lunch, and dinner. However, for snack physiological needs were the primary reason. Second-grade students onward spontaneously produced biological justifications such as the need for energy and nutrition as important reasons for food consumption. These results lend support to the developmental model that children's and adults’ understanding of eating changes in middle childhood.     

THE EFFECT OF TELEVISION AND RADIO ON CHILDREN'S CREATIVITY

The literature on creativity posits that creative abilities are stable and relatively impervious to short-term interventions. Several studies have, however, reported differential effects of media on children's imaginative play and thinking. The results of these studies are difficult to interpret owing to their reliance on nonstandardized measures of creativity. The present study examines the relative effects of television versus radio on children's creativity. Third and sixth graders were presented a story on television or radio and were then given an adapted version of the “Just Suppose” test of divergent thinking developed by Torrance (1974). Responses were scored in terms of ideational fluency, flexibility, and originality. The results indicated that the two media did not have a differential effect on children's creativity.     

Attention and Brain Activity While Watching Television: Components of Viewer Engagement

Television commercials include elements designed to engage the viewer's attention. Manipulations of the commercial's visual structure that result in rapid pacing or frequent scene changes can be engaging because they require a frequent redirection of visual attention. Manipulations of semantic content through such techniques as the inclusion of humorous or anomalous elements can elicit cognitive engagement. Structural manipulations in videos are known to attenuate the alpha (8 to 13 Hz) rhythm of the electroencephalogram (EEG) recorded over posterior cortical regions involved with visual processes. To examine whether other engaging elements also affect the alpha rhythm, EEG was recorded from 10 participants who viewed television commercials. Principal components analysis was used to decompose the alpha rhythm into underlying factors that varied in spatial topography over the head and in spectral composition. Across commercials, the power of a posterior-distributed alpha component was inversely correlated with the frequency of scene changes. In contrast, a frontal component in the lower frequency portion of the alpha band was attenuated during commercials that elicited high subjective interest, independent of scene change frequency. And, an upper-frequency frontal alpha component was attenuated during commercials for which the item being advertised had a high probability of being subsequently recalled, independent of other factors. These frontal patterns of alpha reactivity are consistent with other neuroimaging results concerning frontal lobe activation by executive processes and episodic memory encoding. With appropriate neurologically guided analysis, EEG signals can provide a unique means of monitoring both perceptual and higher order neurocognitive processes during television viewing.
