Developmental changes in imitation from television during infancy.

Infants' (N = 276) ability to learn from television under seminaturalistic conditions was examined in five experiments with 12-, 15-, and 18-month-olds. In all experiments, an adult performed a series of specific actions with novel stimuli. Some infants watched the demonstration live, and some infants watched the same demonstration on television from prerecorded videotape. Infants' ability to reproduce the target actions was then assessed either immediately or after a 24-hour delay. Infants of all ages exhibited imitation when the actions were modeled live. There were age-related and task-related differences, however, in infants' ability to imitate the same actions modeled on television. The role of perceptual, attentional, and cognitive development in the ability to learn from television is discussed.

The response of New Zealand boys to corporate and sponsorship alcohol advertising on television.

A survey of a random sample of 302 New Zealand boys aged 9-14 years investigated responses to two recent television advertisements featuring alcohol companies. Alcohol product advertising is not allowed on New Zealand television but a corporate advertisement which was allowed was perceived by most of the children to be advertising beer and to be encouraging drinking. A corporate sports sponsorship advertisement had lower association with alcohol, which may have been because of children's limited understanding of the concept of sponsorship. Most of the children remembered both advertisements and many expected their peers to take notice of them. There was strong support for both advertisements being broadcast on television. Overall, the survey suggested that this television advertising was creating strong positive associations between the companies' products and significant cultural and emotional elements, thus contributing to a climate that was not supportive of alcohol education.

Evaluation of a television-tape demonstration for the reinforcement of oral hygiene instruction.

The effect of using a television-tape demonstration in order to reinforce the advice given in a self-teaching oral hygiene program was evaluated in the present study. The teeth of 24 periodontal patients were scaled and 2 weeks later oral hygiene instruction was given by handling out a self-teaching manual. The patients were divided into 2 groups, matched with regard to the initial status of oral cleanliness. An experimental group (TV) comprising 12 patients who, 1 week after the instruction, were shown a demonstration of proper oral hygiene technique on closed circuit television and a control group of 12 patients who did not receive this reinforcement. The presence or absence of dento-gingival plaque and gingival bleeding by gentle probing was recorded initially and after 8 weeks on 4 surfaces of all teeth. In addition, plaque scores were recorded at 2 and 3 weeks to assess the effect of the oral hygiene self-instruction. At the final examination after 8 weeks, the patients with plaque on more than 20% of the tooth surfaces were subjected to a tooth cleaning test including a subsequent scoring of remaining plaque. The patients in the experimental group (TV) were asked their opinion regarding the television-tape demonstration. Although the patients in the experimental group expressed a positive opinion about viewing the television-tape demonstration, the improvement in the plaque and gingival bleeding scores recorded at the 8-week examination showed no difference between the 2 groups of patients. Similarly, the scoring of plaque after the tooth cleaning test showed no difference between the 2 groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Overweight and television watching.

Recent work by several United States researchers has provided evidence of a direct correlation between obesity and hours of television viewing per day. This paper considers the association between obesity and hours of television viewing as well as the effect of various confounders on this association with an Australian population. A statistically significant association between amount of television viewing and overweight was found. However, the relatively small sample size and the subsequently wide confidence intervals preclude any firm conclusions. Health promotion efforts to encourage physical activity and to promote the prevention of ill health should be made in routine television programming.

Young children's awareness of violence in Northern Ireland: the influence of Northern Irish television in Scotland and Northern Ireland.

Children aged 5 to 6 years living in either a suburb of London or in a small town in Northern Ireland which has been virtually free from violence, were asked to make up stories in response to a series of pictures depicting such things as derelict houses or a train crash. More Northern Irish children mentioned bombs and explosions than did the London children. To investigate the possibility that this knowledge of explosions might be the result of at least incidental exposure to coverage of such events on Northern Irish television news a further study was initiated. Children from another relatively quiet part of Northern Ireland were compared with children from two separate areas of Scotland where television reception is only possible from Northern Ireland and from a third area in Scotland where Northern Ireland television news cannot be received. Children from those areas where Northern Irish television news can be received again outnumbered those from the control area in terms of mentions of the words bomb or explosion.

A longitudinal study of the effects of television viewing on aggressive and prosocial behaviours.

A longitudinal study investigated the extent to which children's exposure to aggressive and prosocial television models in drama programmes influences their aggressive and prosocial behaviour. In The Netherlands we did not find significant positive correlations between prosocial behaviour and the viewing of prosocial behaviour on television. Positive correlations were found, however, between aggression and television violence viewing. This relationship disappeared almost completely when corrections for the starting level of aggression and intelligence were applied. The hypothesis, formulated on the basis of social learning theory, that television violence viewing leads to aggressive behaviour could not be supported. Our findings are further discussed and compared with the results found in the other countries participating in the international study.

Recognition of television images as a developmental milestone in young children: observational study.

OBJECTIVES: To determine the age at which children with apparently normal development can recognise the television image of a cat, dog, or baby. DESIGN: Observational study. SETTING: District general hospital in north London. SUBJECTS: 797 children with apparently normal development aged between 8 and 23 months and 26 children with Down's syndrome aged 18 months. OUTCOME MEASURES: Whether or not the child recognised the television image of a cat, dog, or baby by naming, imitating, or pointing at the image. RESULTS: By 18 months of age 96% (95% confidence interval 94% to 98%) of normal children recognised the television image of a cat, dog, or baby compared with 5 of 26 (19%) children with Down's syndrome. CONCLUSION: Recognition of the television image of a cat, dog, or baby is a simple milestone, which may help in the developmental assessment of young children.

Unintentional injury depictions in popular children's television programs.

OBJECTIVES: The frequency and magnitude of depictions of risky events and unintentional injuries in top ranked children's animated and live action television programs was assessed. METHODS: Qualitative and quantitative media content analysis were used. Scenes from television episodes were examined for the depiction of risky events and unintentional injuries. RESULTS: A total of 201 actual and potential injury related events were tabulated in 99 episodes aired in 2003 and 2004. Only 26% of the risky events depicted led to an injury or physical consequence. More than 80% of the events involved behavioral or environmental risk factors. Safety factors were not present in over 90% of risky events depicted. The general tone and context of events was humor or indifference rather than concern or action, with little or no relevance to the plot. CONCLUSION: Unintentional injuries are the leading cause of death and disability for children, yet animated and live action television programs marketed to children continue to portray injury risk inaccurately. Working with the children's television production industry to improve injury depiction is a much needed advocacy activity.

Television viewing patterns of hospitalized school-aged children and adolescents.

This descriptive study addressed television viewing as part of hospitalized school-aged children's and adolescents' total daily activities. Thirty-two subjects were observed at half-hour intervals from 7:30 a.m. to 11:00 p.m. Overall, subjects watched television 50.6% of the observational periods. Of the subject and environmental factors considered, only mobility status was significantly related to viewing. Subjects with mobility restrictions had increased viewing hours. The number of subjects watching television significantly decreased when playroom activities were available. Performance of other activities while viewing, and watching television with others, were also significantly related to lower viewing time.

Is "fat free" good for me? A panel study of television viewing and children's nutritional knowledge and reasoning.

The family diet is influenced by children's attitudes toward food, which in turn are influenced by television. In a panel study involving 134 children in 1st to 3rd grade, television viewing, nutritional knowledge, and nutritional reasoning were measured 6 weeks apart. Television viewing predicted subsequent decrements in nutritional knowledge and reasoning, but these findings were significant only for foods that tend to be heavily marketed as weight-loss aids. Television's framing of diet foods may confuse children by equating weight-loss benefits with nutritional benefits.

Optical filters inhibiting television-induced photosensitive seizures.

OBJECTIVE: Televised images are the most common stimulus for provoking photosensitive seizures in photosensitive persons. To inhibit photosensitive seizures in photosensitive persons who do or do not have epilepsy, the authors sought nonpharmacologic methods for reducing the levels of photic stimulation of televised images. BACKGROUND: The authors found two types of pathophysiologic mechanisms (wavelength-dependent and quantity of light-dependent mechanisms) for photoparoxysmal responses (PPR). METHODS: The authors tested two different types of optical filters, one reflecting long-wavelength red light selectively, which stimulates a wavelength-dependent mechanism, and the other absorbing light in the visible spectrum evenly (neutral density filters). Inhibiting effects of optical filters were studied by conventional intermittent photic stimulation (IPS) using strobe light and novel photic stimulation using flashing cathode ray tubes (CRT). RESULTS: Both filters individually inhibited PPR insufficiently (less than 50%). Compound optical filters, composed of both types of filters, can inhibit the PPR, approximately 90% for IPS and 95% for photic stimulation with CRT. These compound optical filters do not destroy chromaticity of emissions from the television's CRT. CONCLUSIONS: These compound filters may be useful to prevent seizures induced by television in photosensitive persons.

Television viewing and adolescents' sexual behavior.

Over the past two decades the sexual content on television has increased in frequency and explicitness but has seldom included depiction of the use of contraceptives. Concurrently, the age of initiation of heterosexual intercourse has decreased and the number of teenaged pregnancies has remained high. Are these trends related? This survey of 391 adolescents found that those who chose heavier diets of sexy television shows were more likely than those who viewed a smaller proportion of sexual content on television to have had sexual intercourse. This relationship held regardless of perceived peer encouragement to engage in sex and across race and gender groups. While causal direction is not clear from these data, the relationship suggests that either sexual activity results in increased interest in sexual content in the media and/or that viewing such content leads to sexual activity. In either case, the finding points to the need for further research and increased discussion and portrayal of the use of contraceptives on television.

Television and music video exposure and adolescent 'alcopop' use.

Alcohol abuse among adolescents is a cause for concern. Around 1995 alcopops (sweetened alcoholic drinks) entered the scene and caused even more concern. Many fear that the sweet taste makes is easier to start drinking for those not yet used to drinking alcohol and the marketing appears aimed at adolescents. Because alcohol use has been linked to television viewing in general and music video viewing in particular this article examined whether a relationship existed between television and music video exposure and the consumption of alcopops. Data were collected with a questionnaire focused on television exposure and alcohol behavior. Respondents were a random sample of 2,546 first- and fourth year schoolchildren of Flanders, the Dutch speaking region of Belgium (60% of the Belgian population). Self reported general TV viewing, music video exposure and drinking of alcopops at home and/or while going out were measured. 68.4% of the respondents watched music videos at least several times a week. The odds of being an alcopop drinker at home increased by 196% for those, who watched music videos at least several times a week (OR = 1.961). For each additional hour of TV viewed per day, the respondents were 17% more likely to be drinkers of altopops at home (OR = 1.169). The odds of being an alcopop drinker, when going out increased by 239% for those who watched music videos at least several times a week (OR = 2.394). For each additional hour of TV viewed per day, the respondents were 19% more likely to be drinkers of alcopops when going out (OR = 1.186). These findings suggest that there is an association between music video exposure and use of alcopops not explained by overall exposure to television. This relationship merits further attention as it is a better predictor of alcopop use, than the control variables and overall TV viewing.

Severely dependent alcohol abusers may be vulnerable to alcohol cues in television programs.

The self-reported ability of 96 alcohol abusers to resist the urge to drink heavily was assessed after they viewed a videotape of a popular prime time television program complete with advertisements. Different versions of the videotape were used to evaluate the effects of a television program with and without alcohol scenes as crossed with the effects of three different types of commercials (i.e., beer, nonalcoholic beverages, food). Before and after viewing the videotape, subjects, who were led to believe that they were participating in two separate and unrelated sets of experimental procedures, completed several drinking questionnaires. Responses to one of the questionnaires provided an unobtrusive measure of self-reported ability to resist the urge to drink heavily. Results indicated that alcohol cues in a television program affected some alcohol abusers' perceived ability to resist the urge to drink heavily. In particular, those with higher alcohol dependence scores showed a decrease in confidence after viewing a television program with alcohol cues compared to subjects who watched the same program but without the alcohol scenes. The clinical implications of these findings are discussed. Until further research is forthcoming, given the artificial nature of the study setting, the results of this study must be viewed with some caution.

Television and music video exposure and risk of adolescent alcohol use.

OBJECTIVE: Alcohol use is frequently portrayed in television programming and advertising. Exposure to media portrayals of alcohol use may lead to increased drinking. To address this issue, we examined prospectively the associations between media exposure and alcohol use in adolescents. DESIGN: Prospective cohort study. Setting. Six public high schools in San Jose, California. Participants. Ninth-grade students (N = 1533; mean age = 14.6 years). OUTCOME MEASURES: Students reported hours of television, music video, and videotape viewing; computer and video game use; and lifetime and past 30 days' alcohol use at baseline and 18 months later. Associations between baseline media exposure and subsequent alcohol use were examined with multiple logistic regression. RESULTS: During the 18-month follow-up, 36.2% of baseline nondrinkers began drinking and 50.7% of baseline drinkers continued to drink. Onset of drinking was significantly associated with baseline hours of television viewing (odds ratio [OR] = 1.09; 95% confidence interval [95% CI] = 1.01-1.18), music video viewing (OR = 1.31; 95% CI = 1. 17-1.47), and videotape viewing (OR = 0.89; 95% CI = 0.79-0.99), controlling for age, sex, ethnicity, and other media use. Computer and video game use was not significantly associated with the subsequent onset of drinking. Among baseline drinkers, there were no significant associations between baseline media use and maintenance of drinking. CONCLUSIONS: Increased television and music video viewing are risk factors for the onset of alcohol use in adolescents. Attempts to prevent adolescent alcohol use should address the adverse influences of alcohol use in the media.

A validity test of movie, television, and video-game ratings.

CONTEXT: Numerous studies have documented the potential effects on young audiences of violent content in media products, including movies, television programs, and computer and video games. Similar studies have evaluated the effects associated with sexual content and messages. Cumulatively, these effects represent a significant public health risk for increased aggressive and violent behavior, spread of sexually transmitted diseases, and pediatric pregnancy. In partial response to these risks and to public and legislative pressure, the movie, television, and gaming industries have implemented ratings systems intended to provide information about the content and appropriate audiences for different films, shows, and games. OBJECTIVE: To test the validity of the current movie-, television-, and video game-rating systems. DESIGN: Panel study. MEASURE: Participants used the KidScore media evaluation tool, which evaluates films, television shows, and video games on 10 aspects, including the appropriateness of the media product for children based on age. RESULTS: When an entertainment industry rates a product as inappropriate for children, parent raters agree that it is inappropriate for children. However, parent raters disagree with industry usage of many of the ratings designating material suitable for children of different ages. Products rated as appropriate for adolescents are of the greatest concern. The level of disagreement varies from industry to industry and even from rating to rating. Analysis indicates that the amount of violent content and portrayals of violence are the primary markers for disagreement between parent raters and industry ratings. CONCLUSIONS: As 1 part of a solution to the complex public health problems posed by violent and sexually explicit media products, ratings can have value if used with caution. Parents and caregivers relying on the ratings systems to guide their children's use of media products should continue to monitor content independently. Industry ratings systems should be revised with input from the medical and scientific communities to improve their reliability and validity. A single ratings system, applied universally across industries, would greatly simplify the efforts of parents and caregivers to use the system as well as the efforts of outside parties to monitor the use and validity of the system.

Effects of open-loop feedback on physical activity and television viewing in overweight and obese children: a randomized, controlled trial.

OBJECTIVES: Television viewing and physical inactivity increase the risk of obesity in youth. Thus, identifying new interventions that increase physical activity and reduce television viewing would be helpful in the prevention and treatment of pediatric obesity. This study evaluated the effects of open-loop feedback plus reinforcement versus open-loop feedback alone on physical activity, targeted sedentary behavior, body composition, and energy intake in youth. METHODS: Thirty overweight or obese 8- to 12-year-old children were randomly assigned to an intervention (n = 14) or control group (n = 16). Participants wore accelerometers every day for 8 weeks and attended biweekly meetings to download the activity monitors. For children in the open-loop feedback plus reinforcement (intervention) group, accumulating 400 counts of physical activity on pedometers earned 1 hour of television/VCR/DVD time, which was controlled by a Token TV electronic device. Open-loop feedback control subjects wore activity monitors but had free access to targeted sedentary behavior. RESULTS: Compared with controls, the open-loop feedback plus reinforcement group demonstrated significantly greater increases in daily physical activity counts (+65% vs +16%) and minutes per day of moderate-to-vigorous physical activity (+9.4 vs +0.3) and greater reductions in minutes per day spent in television viewing (-116.1 vs +14.3). The intervention group also showed more favorable changes in body composition, dietary fat intake, and energy intake from snacks compared with controls. Reductions in sedentary behavior were directly related to reductions in BMI, fat intake, snack intake, and snack intake while watching television. CONCLUSIONS: Providing feedback of physical activity in combination with reinforcing physical activity with sedentary behavior is a simple method of modifying the home environment that may play an important role in treating and preventing child obesity.
