Television producers often use a high rate in the succession of visual and auditory features in their programs to attract the attention of viewers. In this study an attempt was made to measure the formal pace of television programs by scoring the rates of an extensive set of formal visual and auditory characteristics. Sesame Street was chosen as a focal point because this educational program--with its high pace--is very successful in its competition with the majority of commercial programs from which children can choose to watch at home. The analyzed material consisted of 49 Dutch episodes of Sesame Street broadcast between 1977 and 2003. The formal pace characteristics of separate program items from Sesame Street could be reliably established. Factor analysis indicated that clear pace factors were (a) "editing," consisting of a frequent use of different types of shots (total shots, medium shots, and close-ups) combined with a large number of cuts and (b) speech rate. Over a period of 26 years, the pace of editing increased: the mean number of cuts increased from about 4 to 8 per minute. The mean speech rate decreased from 175 to 139 words per minute.  相似文献

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.  相似文献

The current study investigated the impact of different television programming on the social interactions and toy play of preschool children. Same-sex pairs of young children were observed during three types of television programs: cartoons, Sesame Street, and situation comedies. Children were also observed when the television screen was black. Children visually attended to the cartoons the most, Sesame Street less often, and the situation comedy the least. Cartoons dramatically depressed social interaction. Sesame Street elicited the most verbal imitation. Both Sesame Street and the situation comedy allowed the children to divide activity among their peers, the toys, and the television program. Girls verbally imitated program content more than boys. This pattern of findings remained after the children's visual attention to the television was statistically controlled. Several developmental trends were detected. The image of children “mesmerized” in front of the television set, foresaking social interactions and active involvement with their object environment, held true for only one type of programming, namely, cartoons. During the other programs, the children remained active and socially involved.  相似文献

Sesame Street is broadcast to millions of children globally, including in some of the world's poorest regions. This meta-analysis examines the effects of children's exposure to international co-productions of Sesame Street, synthesizing the results of 24 studies, conducted with over 10,000 children in 15 countries. The results indicated significant positive effects of exposure to the program, aggregated across learning outcomes, and within each of the three outcome categories: cognitive outcomes, including literacy and numeracy; learning about the world, including health and safety knowledge; social reasoning and attitudes toward out-groups. The effects were significant across different methods, and they were observed in both low- and middle-income countries and also in high-income countries. The results are contextualized by considering the effects and reach of the program, relative to other early childhood interventions.  相似文献

Summary Street is educational software based on latent semantic analysis (LSA), a computer method for representing the content of texts. The classroom trial described here demonstrates the power of LSA to support an educational goal by providing automatic feedback on the content of students' summaries. Summary Street provides this feedback in an easy-to-grasp, graphic display that helps students to improve their writing across multiple cycles of writing and revision on their own before receiving a teacher's final evaluation. The software thus has the potential to provide students with extensive writing practice without increasing the teacher's workload. In classroom trials 6th-grade students not only wrote better summaries when receiving content-based feedback from Summary Street, but also spent more than twice as long engaged in the writing task. Specifically, their summaries were characterized by a more balanced coverage of the content than summaries composed without this feedback. Greater improvement in content scores was observed with texts that were difficult to summarize. Classroom implementation of Summary Street is discussed, including suggestions for instructional activities beyond summary writing.  相似文献

The impact of both the static and dynamic visual complexity of a half-hour sequence of “Sesame Street” segments upon viewers' visual attention, recall, and recognition are assessed in this study of 48 four and five year olds. Previous research has produced inconsistent results with respect to the links among the three sets of variables in this observational learning process. Results of a path analysis indicated strong negative relationships between static complexity and all three viewer variables, positive relationships between dynamic complexity and both attention and recognition, and between attention and both types of learning. No significant relationship emerged between dynamic complexity and recall. Implications for television production aimed at young children are discussed.  相似文献

This study assessed whether infant-directed videos designed to promote parent-child interactions actually support such engagement. Parents watched videos from the Baby Einstein or the Sesame Beginnings series for 2 weeks at home with their 12- or 18-month-old infants. Baby Einstein encourages parents to label objects and actions; Sesame Beginnings models activities in which parents can engage with their children. A control group was not provided videos for home viewing. In laboratory sessions, parent-child interactions were recorded during free play without TV, during the presentation of one of the videos, and immediately after watching. During viewing, interactions decreased in quantity and quality across groups; however, parents used video content as a basis for interaction. Coviewing Sesame Beginnings at home was positively associated with quantity of parent-child interaction during the initial free-play session. Furthermore, the quantity and quality of interactions were greater immediately following viewing of Sesame Beginnings than with Baby Einstein.  相似文献

This study investigated the effects of familiarization and attention on event-related potential (ERP) correlates of recognition memory in infants. Infants 4.5, 6, or 7.5 months of age were either familiarized with 2 stimuli that were used during later testing or presented 2 stimuli that were not used later. Then, infants were presented with a recording of Sesame Street to elicit attention or inattention and presented with familiar and novel stimuli. A negative ERP component over the frontal and central electrodes (Nc) was larger in the preexposure familiarization group for novel- than for familiar-stimulus presentations, whereas the Nc did not differ for the group not receiving a familiarization exposure. Spatial independent components analysis of the electroencephelogram and "equivalent current dipole" analysis were used to examine putative cortical sources of the ERP components. The cortical source of Nc was located in areas of prefrontal cortex and anterior cingulate cortex.  相似文献

A review of previous studies on children's comprehension of visual formal features did not warrant predictions about children's understanding of the formal features as used in three items from Sesamstraat, the Dutch version of Sesame Street. Therefore, a study was designed in which 45 children in the age range of 4–6 years watched the items and were interviewed. In the first item, a split screen was used to visualize simultaneity of actions. The second item used a subjective camera to suggest the construction of a home video by one of the characters. Version 1 of this item did not show the character while making home video, whereas Version 2 did show the character while filming. The third item contained a dissolve (Version 1) or a cut (Version 2) to indicate the end of a dream. A general conclusion was that although older children (mean AGE=5.9 years) understood the visual formal features better than younger children (mean AGE=4.4 years), the extent to which children in both age groups understood the visual formal features appeared to vary between items and versions. Most children in both age groups understood the split screen in the first item. The younger age group did not understand the subjective camera if the making of the home video was not shown. Both the younger and the older age group understood the version with the cut better than the original version with the dissolve. In the discussion, the question was addressed what the findings of this study and previous studies teach us about children's understanding of visual formal features in general.  相似文献

Two of the most prominent evolutionary debunking arguments are Sharon Street's Darwinian Dilemma for Normative Realism and Alvin Plantinga's Evolutionary Argument against Atheism. In the former, Street appeals to evolutionary considerations to debunk normative realism. In the latter, Plantinga appeals to similar considerations to debunk atheism. By a careful comparison of these two arguments, I develop a new strategy to help normative realists resist Street's debunking attempt. In her Darwinian Dilemma, Street makes epistemological commitments that ultimately support Plantinga's structurally similar argument. If Street succeeds in debunking normative realism, I argue, then she also succeeds in debunking atheism. But atheism is a suppressed premise of the Darwinian Dilemma as well as a commitment of almost all normative anti‐realists. If Street's argument entails theism, then the Darwinian Dilemma is internally incoherent and should be abandoned by almost everyone. 1  相似文献

This study examined whether coping moderated the impact of community violence exposure (CVE) on violent behavior among 285 urban African American and Latino adolescent males assessed annually across 5 years. Composites indicating overall CVE (having knowledge of others’ victimization, witnessing violence, direct victimization) and approach to coping with CVE were created by averaging across years 1–3 (Time 1; mean ages 14–16). Adolescents classified as coping effectively tended to respond to CVE in beneficial ways (e.g., developing long-term solutions, engaging in positive reappraisal). Violent behavior was examined across years 1–3 (Time 1) and years 4–5 (Time 2; mean ages 18–19). CVE was longitudinally associated with greater violent behavior, adjusting for Time 1 levels of violent behavior. This association was significant only among adolescents with less effective coping strategies. Interventions targeting the enhancement of coping skills may be an effective method of reducing the impact of CVE on adolescent violent behavior. Sonya S.

Acknowledging the productive impulses of the affective turn, this paper examines the affective impacts of urban architecture conveyed by Horatio Alger in his novel Ragged Dick. Without any strict adherence to a particular school of thought, I draw instead on those concepts and theories that promise enriching for an analysis of a nineteenth-century Bildungsroman and its socio-spatial representation of New York's architecture, for instance Central Park and Wall Street. The results underline the flexibility of the affective nexus used in literary geographies, finding the metropolis not as a passive dramaturgical backdrop but as an active agent, whose structural composition works towards the integration of its literary subjects into the affective discourses of its historical period and literary genre. Horatio Alger's Ragged Dick directs this very agency towards the protagonist's integration into the hegemonic structures of sentimentality. In the story, this becomes visible in the mythical abilities of empathy to transcend class divisions and the reconciliatory appeal of the capitalist ideology. Ultimately, affect and emotionality are used to maintain and perform the proper feelings for certain architectural structures, manifesting themselves as a sentimental performance of systemic allegiance.  相似文献

Using confirmatory factor analyses, we examined method effects on Rosenberg's Self-Esteem Scale (RSES; Rosenberg, 1965) in a sample of older European adults. Nine hundred forty nine community-dwelling adults 60 years of age or older from 5 European countries completed the RSES as well as measures of depression and life satisfaction. The 2 models that had an acceptable fit with the data included method effects. The method effects were associated with both positively and negatively worded items. Method effects models were invariant across gender and age, but not across countries. Both depression and life satisfaction predicted method effects. Individuals with higher depression scores and lower life satisfaction scores were more likely to endorse negatively phrased items.  相似文献

This experimental research focuses on four distinct, but related theoretical interests regarding the study of emotion and media effects: (a) emotion serving as a potential mediator of the relationship between the consumption of multiple media messages, (b) media messages sparking emotional reactions to attitude objects not specifically referenced or identified in a message, (c) the assessment of inter-emotion relationships across distinct attitude objects, and (d) varied processes of emotion-based influence based on individual-difference attitude object preferences. This work focuses on Michael Moore's Fahrenheit 9/11, its effects on anger felt toward President George W. Bush and Senator John F. Kerry, and subsequent perceptions of candidate debate superiority across Bush versus Kerry supporters. Moore's film was found to influence levels of anger felt toward both Bush and Kerry and these emotions were related to subsequent perceptions of debate superiority. Distinct processes of influence were found for previously identified Bush supporters versus Kerry supporters, with Bush anger serving as a mediator for Bush supporters and Kerry anger serving as a mediator for Kerry supporters. Ramifications of this study's findings are outlined and future lines of research are summarized.  相似文献

Goossens' review (2012, this issue) nicely maps the progression of scientific research from its early focus on loneliness as a dysphoric state that results from the discrepancy between a person's ideal and actual social relationships to its current emphasis on the centrality of loneliness to our very nature as a social species, and he argues that developmental science throughout Europe has a great deal to contribute to our understanding of this construct. He concludes that psychologists should care about research on loneliness for five reasons: (i) it is a well-defined phenotype; (ii) it shows both high stability and individual differences in rates of change across years; (iii) it has adaptive value and evolutionary significance; (iv) it has a genetic substrate that is moderated by social environments; and (v) it has self-maintaining features that can lead to adverse mental health outcomes. Goossens' review is rife with information and ideas. We focus here on two additional important reasons and on the phenotype of loneliness.  相似文献

Research has shown that greater stress responses predict worse sleep and that the quality of one's current romantic relationship predicts one's sleep. Despite these established links, research has not examined connections between ongoing patterns of interpersonal experiences and competencies (relationship effectiveness) and stress exposure on sleep. Participants in the Minnesota Longitudinal Study of Risk and Adaptation (MLSRA) completed measures assessing relationship effectiveness and stress exposure at ages 23 and 32 years, as well as sleep quality/duration at age 37 years. Analyses demonstrate that relationship effectiveness at age 23 years positively predicts sleep quality—but not sleep duration—at age 37 years via reduced stress exposure at age 32 years. These findings highlight the effects of relationship effectiveness and stress exposure across early to middle adulthood on sleep.  相似文献

Fifteen years ago, Sharon Street and Richard Joyce advanced evolutionary debunking arguments against moral realism, which purported to show that the evolutionary history of our moral beliefs makes moral realism untenable. These arguments have since given rise to a flurry of objections; the epistemic principles Street and Joyce relied upon, in particular, have come in for a number of serious challenges. My goal in this paper is to develop a new account of evolutionary debunking which avoids the pitfalls Street and Joyce encountered and responds to the most pressing objections they faced. I begin by presenting a striking thought experiment to serve as an analogy for the evolution of morality; I then show why calibrationist views of higher-order evidence are crucial to the evolutionary debunking project; I outline a new rationale for why finding out that morality was selected to promote cooperation suggests that our moral judgments are unreliable; and I explain why evolutionary debunking arguments do not depend on our having a dedicated faculty for moral cognition. All things considered, I argue, evolutionary debunking arguments against moral realism are on relatively secure footing – provided, at least, that we accept a calibrationist account of higher-order evidence.

The capacity for teacher expectation effects to interact and compound across a child's schooling offers a largely untested mechanism for magnifying or minimizing effects. This study examined four types of long-term teacher expectation effects: within-year effects of single teachers, cross-year effects of single teachers, mediated effects of single and multiple teachers, and compounded effects of multiple teachers. Participants were 110 students tracked from preschool through Grade 4 on measures of achievement and teacher expectations. Evidence was found for within-year but not direct cross-year effects. However, path models demonstrated enduring indirect effects of teacher expectations on cross-year achievement. Multiple years of teacher expectation effects were additive in predicting student achievement at fourth grade, with similar effects for teachers' over- and underestimates of student ability. The study extends understanding of longer-term teacher expectation effects.  相似文献
