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.     

The Nature and Predictive Value of Mothers' Beliefs Regarding Infants' and Toddlers' TV/Video Viewing: Applying the Integrative Model of Behavioral Prediction

Viewing television and video programming has become a normative behavior among U.S. infants and toddlers. Little is understood about the extent of parents' decision making regarding their young children's viewing, although numerous organizations are interested in reducing time spent viewing among infants and toddlers. Prior research has examined parents' belief in the educational value of TV/videos for young children and the predictive value of this belief for understanding infant and toddler viewing rates, although other possible salient beliefs remain largely unexplored. This study employs the integrative model of behavioral prediction to examine 30 maternal beliefs about infants' and toddlers' TV/video viewing, which were elicited from a prior sample of mothers. Results indicate that mothers tend to hold more positive than negative beliefs about the outcomes associated with young children's TV/video viewing and that the nature of the aggregate set of beliefs is predictive of their general attitudes and intentions to allow their children to view, as well as children's estimated viewing rates. Analyses also uncover multiple dimensions within the full set of beliefs, which explain more variance in mothers' attitudes and intentions and children's viewing than the uni-dimensional index. The theoretical and practical implications of the findings are discussed.     

Researching Blue's Clues: Viewing Behavior and Impact

Blue's Clues is a preschool television series designed to promote mastery of thinking and problem-solving skills. This paper summarizes a series of studies concerning the impact of the program on television viewing behaviors and on cognitive development. Three studies of viewing behavior indicate that as preschool children were in the process of learning from the program they were relatively quiet and highly attentive. As they mastered the content they became increasingly vocal and interactive. Their tendency to interact with Blue's Clues transferred to another program from a different series. A longitudinal study comparing children who regularly watched Blue's Clues to demographically similar children who could not receive the program indicated that the program had a positive impact on cognitive development.     

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.     

A parent-administered program to reduce children's television viewing

A parent-administered program to reduce television viewing of primary school-aged children was tested on two boys and three girls from three different families who were heavy viewers of television. Children were given 20 unearned tokens each week by their parents, which they could exchange for up to 10 hours of viewing time. The child earned a gold token for viewing in accordance with the rules for 4 consecutive weeks, which was exchanged for a reward. Parents were given instructions to follow the program independently. Data on hours of television viewing, homework, and reading were recorded each day by one or both parents. A multiple-baseline analysis of the effects of the TV reduction program indicated that children reduced their baseline television viewing by more than half once the program was implemented, and continued to maintain these changes 6 months and 1 year after the program was discontinued. Reading time increased for all children whereas effects on homework varied across children. The results support the effectiveness of a parent-administered program for nonbehavior problem children who watch excessive amounts of television.     

Effects of television preplay formats on children's attention and story comprehension

Childrens' visual attention to, and comprehension of, a television program was measured as a fucntion of inserts called preplays that varied on two orthogoal dimensions: (1) Presence or absence of visual excerpts from the program, and (2) concrete or inferential story narration. Visual fixation was coded continously for 64 pairs of same-sex children, in 1st 4th grades, while they viewed the television program with one of four types of prepalys. After veiwing, each child answered items assessing his or her comprehension of the visual and verbally presented content. Children who viewed visual preplays attended longer than did children who viewed nonvisual preplays. Visual presentation predicted comprehension of content presented in a visual mode, whereas inferential narration predicted comprehension of implicit content presented in a verbal mode. The results suggest that information processing is modality specific: Visual presentation affects visual processing and abstract language affects verbal processing. The results do not suport the hypothesis that visual presentation interfere with linguistic processing.

The Understanding of Pans in 3- to 6-Year-Old Children

In this study, we examined the extent to which preschool children were able to understand pans (continuous sideward shifts of a scene generated by rotating the camera around a virtual axis), one of the most typical technical elements of films. This was done by showing 60 participating children a film in which a teddy bear asked them questions about pan sequences. The questions could be answered correctly only if the underlying pan was understood. The study revealed that the increase in the children's comprehension of the pans was significantly correlated with age and was facilitated by gains in visual working memory (VWM). It was found that VWM in 3 year olds is generally so low that they are still not able to understand any pan sequences. Most of the pans were understood by those children who could remember the locations of two simple objects. This VWM level is sex dependent and is usually reached by boys at age 4 and by girls at age 5; thus, boys understand pans quite a bit earlier. Perception speed, pan speed, and television consumption played rather limited roles. An appropriate model for the understanding of pans is subsequently introduced and discussed.     

Children’s understanding of television programmes: Three exploratory studies

Three studies were designed to explore children’s understanding of television programmes. Seventy-two children from 6 to 9 years of age and attending a primary school, viewed one adult and one children’s television programme. They took part in procedures that examined their 1) memory for crucial plot events immediately after viewing, 2) understanding of the motives of the protagonists, and 3) character evaluation of the protagonists. The results yielded age differences in these abilities and suggested variable recall, poor comprehension, in terms of being able to relate motives to consequences, and confused character evaluation when the heroes and villains were not clearly discriminated. The results are interpreted in relation to the television literature, reading comprehension and children’s desire to make sense of what they see.     

Direct and indirect directives: What do young children understand?

This study deals with the comprehension of direct and nonconventional indirect directives by children 3 to 6 years old. It refers to both the philosophies of language and the psychological theories that favor the social and cognitive factors of language acquisition. Twenty-four 3- and 4-year-old children and twenty-four 5- and 6-year-old children performed a story completion task presented in the form of comic strips. The variables studied were children's age. linguistic nature of the utterance (direct or nonconventional indirect directives), and strength of the production context (strong or weak context). The results were (a) in contrast to most other studies, direct directives were better understood than indirect directives: (b) the comprehension of both indirect and direct directives depended on the production context of utterance; (c) 5- and 6-year-old children performed better than 3- and 4-year-old children. The detailed results are discussed in terms of types of comprchension of directives linked to comprehension of the speaker's intention.     

Reducing Excessive Television Viewing

Excessive television watching among children can have several negative consequences, including exposure to frequent violent and aggressive scenes and limitations in their opportunities to engage in alternative educational and prosocial activities. In the present study, a youngster evidencing high levels of television viewing behavior was placed on a modified token economy: earned tokens were used to activate the television for set periods of time. With onset of the intervention, immediate and dramatic reductions in television viewing were noted. High levels returned during a return to baseline phase, but reductions again occured when the intervention was reimplmented. Positive second-order effects were noted in the child's school work, in the amounts of time the family spent together, and in the mother's perception of a social support variable.     

Effects of television exposure on developmental skills among young children

BackgroundLiterature addressing the effects of television exposure on developmental skills of young children less than 36 months of age is scarce. This study explored how much time young children spend viewing television and investigated its effects on cognitive, language, and motor developmental skills.MethodsData were collected from the Pediatric Clinics at University Medical Center in Southern Taiwan. The participants comprised 75 children who were frequently exposed to television and 75 children who were not or infrequently exposed to television between 15 and 35 months old. The age and sex were matched in the two groups. The Bayley Scales of Infant Development-second edition and Peabody Developmental Motor Scales-second edition were used to identify developmental skills. Independent t-tests, χ² tests, and logistic regression models were conducted.ResultsAmong 75 children who were frequently exposed to television, young children watched a daily average of 67.4 min of television before age 2, which was excessive according to the American Academy of Pediatrics. Viewing television increased the risk of delayed cognitive, language, and motor development in children who were frequently exposed to television. Cognitive, language, and motor delays in young children were significantly associated with how much time they spent viewing television. The type of care providers was critical in determining the television-viewing time of children.ConclusionWe recommend that pediatric practitioners explain the impacts of television exposure to parents and caregivers to ensure cognitive, language, and motor development in young children. Advocacy efforts must address the fact that allowing young children to spend excessive time viewing television can be developmentally detrimental.     

Young children's television viewing and the quality of their interactions with parents: A prospective community study

Television is one of the most commonly viewed forms of media by children throughout the world. Excessive television viewing can influence the quality of children's relationships and interactions with their parents. We examined the emotional availability (EA ) of children toward their parents by assessing child responsiveness and child involvement , using a cross‐sectional and longitudinal design. We employed a large and representative community sample of Norwegian 4‐year‐olds (n = 995) who were followed up at 6 years old (n = 795). The results illustrate that, when viewing excessive amounts of television, children are less likely to be involved with their parents in ordinary toy‐play. We argue in favor of the displacement hypothesis, stating that time‐demanding technologies are negatively related to the quality of parent–child relationships because spending more time watching television will leave less time for developing nurturing social relationships.     

时间距离对记叙文倒叙信息表征的影响

采用移动窗口技术和探测——再认范式探讨了时间距离对记叙文倒叙信息表征的影响。本研究分为两个实验：实验1考察了在近时间距离条件下读者如何表征倒叙信息,结果发现读者会根据时间顺序,把倒叙信息整合到他们的表征中去,支持时间顺序假设;实验2考察了在远时间距离条件下读者如何表征倒叙信息,结果发现读者会根据文本叙述顺序,将倒叙信息作为背景信息整合到该事件中去,支持背景假设。上述结果表明,时间距离是影响读者如何对倒叙信息进行表征的重要因素。     

Maternal Characteristics Associated with Television Viewing Habits of Low-Income Preschool Children

Few studies have examined maternal characteristics associated with heavy or inappropriate television viewing on the part of their children. We investigated the relationship between children’s television viewing habits and maternal depressive symptoms and parenting beliefs. The participants were 175 low income children (mean age = 62.1 months) and their mothers who participated in a larger national study of Early Head Start eligible children. Our sample included families from two predominantly rural sites. Mothers completed a survey about the amount of time their children spend watching television during the week and on the weekend, and the types of programs they watch, as well as questionnaires related to maternal depression and parenting attitudes. According to mothers’ report, most of the young children in our sample exceeded the total viewing time recommended by the American Academy of Pediatrics (maximum 2 h per day), and the majority watched at least some programming designed for adult audiences. Maternal depressive symptoms and beliefs about parenting were associated with heavier viewing on the part of the child, as well as with viewing of age-inappropriate content.     

An in-home investigation of maternal teaching strategies during Sesame Street and a popular situation comedy

A naturalistic in-home investigation of maternal teaching strategies while viewing an educational program (Sesame-Street) and an entertainment program (a situation comedy) was conducted. Fourteen mothers and their pre-school children tape-recorded their coversations while jointly viewing the two television programs. Mothers tooks the role of teacher during both types of programs, but they talked more and asked proportionally more questions about the content of Sesame Street than they did about the content of the situation comedy. Likewise, during Sesame Street, mothers talked more about educationally relevant concepts such as size, color, and number. Children, while watching Sesame Street, engaged in ore labeling of educationally relevant concepts than they did while viewing the situation comedy. During the situation comedy, mothers explained why television characters performed particular behaviors and assigned traits and emotions to characters more frequently than they did during Sesame Street. The findings suggest that the parent may play an important role in helping children maximally utilize television as a teacher.     

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.     

The Role of Television in the Socialization of Nonverbal Behavioral Skills

This study examined the relation between level of television viewing and ,nonverbal behavioral encoding skills among school-aged children. As predicted, frequent TV viewers communicated emotions common on television (happiness and sadness) better than emotions uncommon on television (disgust and fear/surprise), a pattern that did not emerge for infrequent TV viewers. Additionally, compared with infrequent TV viewers, frequent viewers were better encoders of spontaneous nonverbal displays, but worse encoders of posed displays. The results of a follow-up study suggest that this latter pattern may reflect a failure by children who are exposed to highly expressive television models to engage in active self-regulation of their nonverbal expressions.
