Comprehension of televised stories by preschool children with ADHD.

Investigated visual attention to and story comprehension of televised stories in 4- to 6-year-old children with attention deficit hyperactivity disorder (ADHD) and comparison children. Half of the children in each group watched the program with toys in the room, and the other half watched without toys. Visual attention to the television was recorded, and story comprehension was assessed by performance on cued recall questions. All children attended significantly less when toys were present, but the difference when toys were present was greater for children with ADHD. The groups did not differ on recall of factual information when toys were absent. When toys were present, the comparison children showed no decrement in performance on factual questions, whereas the performance of children with ADHD was significantly worse. On questions testing causal connections, the children with ADHD performed more poorly than comparison children regardless of whether toys were present. Implications of these results for understanding and treating the academic and social difficulties of children with ADHD are discussed.

Update on the recommended viewing protocol for FAXIL threshold contrast detail detectability test objects used in television fluoroscopy.

The significance of varying the viewing conditions that may affect the perceived threshold contrast of X-ray television fluoroscopy systems has been investigated. Factors investigated include the ambient room lighting and the viewing distance. The purpose of this study is to find the optimum viewing protocol with which to measure the threshold detection index. This is a particular problem when trying to compare the image quality of television fluoroscopy systems in different input field sizes. The results show that the viewing distance makes a significant difference to the perceived threshold contrast, whereas the ambient light conditions make no significant difference. Experienced observers were found to be capable of finding the optimum viewing distance for detecting details of each size, in effect using a flexible viewing distance. This allows the results from different field sizes to be normalized to account for both the magnification and the entrance air kerma rate differences, which in turn allow for a direct comparison of performance in different field sizes.

Low recall of local television health care news segment topics, sponsors and program names.

In an effort to examine the effectiveness of hospitals' sponsoring of local broadcast news health care segments, viewer recall of information presented in news reports, the program name of the reports, and the names of the hospital sponsors of those reports were analyzed. Despite the fact that telephone survey respondents said they place a higher value on televised health care information than they do for other mass media, recall was found to be generally poor. A majority of respondents could not name the topic of the televised health news report they had viewed, the program name or the program sponsor.

Television viewing and early initiation of sexual intercourse: is there a link?

Using data from the National Survey of Children, this paper examines the hypothesis that the amount of time children spend viewing television and the extent to which the content viewed is sexual in nature is related to the initiation of sexual activity. Several theories that would lead to this hypothesis are reviewed. The data do not provide any strong or consistent evidence for such links. However, some aspects of the context in which television is viewed are related to sexual activity. The authors suggest ways in which the design and measures could be strengthened to provide a more rigorous test of the hypothesis.

Stereotype or success? Prime-time television's portrayals of gay male, lesbian, and bisexual characters.

The current content analysis of prime-time network television during the fall of 2001 seeks to identify the representation of Gay male, Lesbian, and Bisexual characters in shows known to have one reoccurring homosexual character based on the theories of Clark and Berry. Clark (1969) established four stages of media representation for minority groups: non-representation, ridicule, regulation, and respect. The findings of the study support the premise that Gay males and Lesbians have passed Clark's stage of non-representation and have progressed into the stage of ridicule and some are moving into the stages of regulation and respect. Berry (1980) devised three periods based on the television portrayal of Blacks: The Stereotypic Age, The New Awareness, and Stabilization. Results were mixed, with only a partial support of the hypothesis that Gay males and Lesbians had advanced beyond The Stereotypic Age.

Using television to reach older people with prevention messages: the Over Easy experiment.

Results are presented from the 1978 multi-method national summative evaluation of the goal-directed television program, Over Easy. Targeted to persons 55 years of age and older, and setting informational, attitudinal and behavioral objectives, the Over Easy program successfully communicated prevention information, conveyed a positive philosophy of aging, and encouraged target group utilization of existing social services. Three design features of the Over Easy intervention are recommended for future social interventions attempted through television.

Viewer reaction to different television captioning speeds.

Video segments captioned at different speeds were shown to a group of 578 people that included deaf, hard of hearing, and hearing viewers. Participants used a five-point scale to assess each segment's caption speed. The "OK" speed, defined as the rate at which "caption speed is comfortable to me," was found to be about 145 words per minute (WPM), very close to the 141 WPM mean rate actually found in television programs (Jensema, McCann, & Ramsey, 1996). Participants adapted well to increasing caption speeds. Most apparently had little trouble with the captions until the rate was at least 170 WPM. Hearing people wanted slightly slower captions. However, this apparently related to how often they watched captioned television. Frequent viewers were comfortable with faster captions. Age and sex were not related to caption speed preference; nor was education, with the exception that people who had attended graduate school showed evidence that they might prefer slightly faster captions.

Closed-captioned television presentation speed and vocabulary.

This study summarizes an extensive research project on closed-captioned television. Caption data were recorded from 205 television programs. Both roll-up and pop-on captions were analyzed. In the first part of the study, captions were edited to remove commercials and then processed by computer to get caption speed data. Caption rates among program types varied considerably. The average caption speed for all programs was 141 words per minute, with program extremes of 74 and 231 words per minute. The second part of the study determined the amount of editing being done to program scripts. Ten-minute segments from two different shows in each of 13 program categories were analyzed by comparing the caption script to the program audio. The percentage of script edited out ranged from 0% (in instances of verbatim captioning) to 19%. In the third part of the study, commonly used words in captioning and their frequency of appearance were analyzed. All words from all the programs in the study were combined into one large computer file. This file, which contained 834,726 words, was sorted and found to contain 16,102 unique words.

Pregnancy information and advice on Sky television: an evaluation.

This paper is one of a series produced as part of an evaluation of a number of digital interactive television (DiTV) health pilots funded by the Department of Health during 2001/2002. This paper is concerned with two pregnancy health services produced by Channel Health and hosted on Sky television. The study aimed to discover the success or otherwise of health information on pregnancy in this form and on this medium or "platform". In particular we were interested in what kinds of people on the broader national stage viewed the Bush Babies programme. Data were obtained through a telephone questionnaire of Channel Health users. More than 250 people took part. More than 175 000 households watched the programmes, a large audience for this type of programme. Bush Babies attracted a sizeable audience with over a quarter of Channel Health viewers in this study having seen it. There proved to be marked differences between the types of people using the service and in the patterns of their use--and not always in the ways one might have expected. As expected, people who were single, older or male were less likely to view Bush Babies, while younger, married or cohabitants and females were more likely to watch the programme. More unexpectedly, perhaps, the fact that the person was pregnant was not a predictor of whether they saw a Bush Babies programme or the number of the programmes watched.

Television captions for hearing-impaired people: a study of key factors that affect reading performance.

Closed captions are broadcast with television programs for special-needs viewers such as hearing-impaired people. We examined how caption presentation rate, small amounts of induced dioptric blur, and English learned as a second language affect the reading performance of good readers. Thirty-two college graduates with normal hearing and vision, half of whom learned English as a second language, read television captions that consisted of white capital letters equivalent in size to 20/92 Snellen letters on a black background. Text was presented at rates of 55, 120, and 216 words/min. Lenses of 0, 0.5, 1.0, or 1.5 diopters (D) were worn over the person's best refractive correction. The fastest text rate and small amounts of blur significantly disrupted reading performance. People who learned English as a second language were hindered more by presentation rate than by dioptric blur. Surprisingly, people with refractive errors (even though they were optically corrected) were hindered less by induced blur than were people with normally clear vision.

American Academy of Pediatrics: Children, adolescents, and television.

This statement describes the possible negative health effects of television viewing on children and adolescents, such as violent or aggressive behavior, substance use, sexual activity, obesity, poor body image, and decreased school performance. In addition to the television ratings system and the v-chip (electronic device to block programming), media education is an effective approach to mitigating these potential problems. The American Academy of Pediatrics offers a list of recommendations on this issue for pediatricians and for parents, the federal government, and the entertainment industry.

[Amount and quality of food advertisement on Brazilian television].

The main objective of the study was to analyze the amount and quality of food advertisement on Brazilian television in three different times of the day. The results showed that food products, when compared to other products, were the most frequently advertised, regardless of the time of the day in a given week analyzed. Television promotes food predominantly high in fat and/or sugar and salt. The large number of high fat and/or sugar and salt products advertised can contribute to changing food habits of children and teenagers, and increasing the incidence of obesity in the population.

Light microscopic and color television image analysis of the development of staining on chlorhexidine-treated surfaces.

Tooth staining with the use of chlorhexidine preparations is the major problem of long term application. Evidence suggests that the staining arises from a cationic/anionic interacation of chlorhexidine with components of certain dietary materials. The purpose of this in vitro study was to compare visually the development of tea and coffee staining on acrylic and tooth specimens treated with chlorhexidine and to follow the development of tea staining on perspex by light microscopy and color television image analysis. All specimens were maintained in their respective beverage for 5 days with test specimens removed three times a day and placed for 2 minutes in an 0.2% chlorhexidine solution. Both test tooth and acrylic specimens showed comparably and markedly increased staining by the beverages compared with control specimens. Color television image analysis of test specimens demonstrated more marked and rapid development of tea staining when studied on a daily basis. Microscopic examination revealed the staining to be made up of small particles of material which increased in size and coalesced with time. Again, marked differences were apparent in the stain on test and control specimens. The results of this in vitro method provided further evidence for a dietary aetiology to chlorhexidine staining and were consistent with clinical findings. Such a method may be useful to assess staining arising from the use of other anti-plaque agents.

Television beer advertising and drinking knowledge, beliefs, and intentions among schoolchildren.

OBJECTIVES: The relationships between television beer advertising and drinking knowledge, beliefs, and intentions were investigated in a survey of schoolchildren. The research was guided by a theoretical model specifying that awareness of advertising, and not mere exposure, is necessary for it to have an effect on beliefs or behaviors. METHODS: Participants were a random sample of 468 fifth- and sixth-grade schoolchildren from a northern California community. Data were collected in the home with a combination of self-administered questionnaires and structured interviews. RESULTS: Nonrecursive statistical modeling indicated that awareness of television beer advertising was related to more favorable beliefs about drinking, to greater knowledge of beer brands and slogans, and to increased intentions to drink as an adult. The effects of advertising awareness on knowledge, beliefs, and intentions were maintained when the reciprocal effects of beliefs, knowledge, and intentions on awareness were controlled. CONCLUSIONS: The findings suggest that alcohol advertising may predispose young people to drinking. As a result, efforts to prevent drinking and drinking problems among young people should give attention to countering the potential effects of alcohol advertising.

Visual superiority effect in televised prevention of victimization programs for preschool children.

Preschool children have been reported to remember more visual than auditory content from television programs. 80 preschool children were randomly assigned to conditions where visual or auditory components of a televised program on personal safety were manipulated. Visually modeled actions were slightly more salient for preschool-age children than actions represented auditorily. The combination of visual and auditory input provided the superior educational method.

Televised violence: a Japanese, Spanish, and American comparison.

In Japan, Spain, and the USA during one week acts of violence (verbal and nonverbal) were rated on the Index of Television Violence by 3 raters in each country. In all three countries televised violence was more likely depicted in interpersonal conflict than against property. Fewer scenes of physical or fatal injury appeared in Japan than in the other two countries. Other observations were made. Replication is urged.

Attention to television: intrastimulus effects of movement and scene changes on alpha variation over time.

Central and occipital EEG alpha were used as an on-line measure of momentary changes in covert attention during television viewing. Alpha was recorded during nine 30-second commercials shown embedded in a half-hour situation comedy. Two time series were constructed for data analysis. A stimulus series consisted of codes representing the presence or absence of scene changes or person and object movement for each half-second interval of the commercials. The alpha series consisted of median alpha scores for each half-second interval, aggregated across 26 subjects. The alpha series was regressed on the movement and scene change series, both of which produced significant increments in R, even after autocorrelational effects inherent in the alpha series were removed. As a validity check on the attentional interpretation of alpha, it was shown that mean alpha for each commercial was significantly (negatively) correlated with recall and recognition of commercial contents. The results are discussed in terms of their implications for further use of continuously-recorded alpha in research on factors that influence attention to television.
