2 studies examined children's comprehension of brief stop-animation televised segments incorporating elements of cinematic montage such as pans, zooms, and cuts. Children reconstructed the action and dialogue in these segments using the same dolls and settings depicted. In Study 1, there was no effect of cinematic techniques on reconstruction performance of 3- and 5-year-olds as compared to control segments filmed without these techniques. The results challenged the assumption that the use of such techniques per se contributes to young children's poor comprehension of television shows. In Study 2, 12 new segments were produced in which comprehending the montage required inferences of character perspective, implied action sequences, spatial relationships, and simultaneity of different actions. Averaging across all segments, 62% of the 4-year-olds and 88% of the 7-year-olds demonstrated clear comprehension of the montage. Inferences concerning implied action sequences were easiest for both ages. Inferences of simultaneity were most difficult for 4-year-olds, whereas inferences of character perspective were most difficult for 7-year-olds. Preschool children are thus capable of understanding cinematic events conveyed through camera techniques and film editing, despite previous assertions to the contrary. This ability nevertheless substantially increases with age.  相似文献

One way of enhancing appreciation of cultural diversity within the American Deaf community is by collecting and analyzing stories about Deaf people of color. The authors examined biographical profiles in national print and visual media published since 1988. The materials focused on life stories of individuals identified as Deaf persons of color (e.g., Deaf and identified as Black/African American, Hispanic/Latino, Asian/Pacific Islander, or American Indian/Alaskan Native). Anecdotes were selected that provided a sociocultural rather than medical or pathological perspective and reflected the featured individual's viewpoint. Four categories of shared experiences emerged: experiences related to overcoming obstacles to educational opportunities, stories about individuals who influenced the direction the featured individual took in life, childhood and family experiences, and experiences relating to stereotypes, cultural conflicts, or discrimination. The authors conclude by discussing lessons and messages derived from the stories.  相似文献

A three-phase investigation of the effects of duration and number of inescapable shocks with rats was conducted. In the first phase (shock treatment), separate groups were exposed either to 64 or 128 5-sec shocks or to 32, 64, or 128 10-sec shocks. Measures of intrashock activity were found to be lower for the groups exposed to 64 or 128 10-sec shocks than for any other group. In the second phase (Test Day 1), half of each group was tested for interference with FR 1, locomotor escape-avoidance learning at either 24 or 168 h following cessation of shock treatment, using a control procedure that was designed to equate groups for exposure to test shock. The results indicated that, relative to nonshock-treated controls, at each interval only the groups previously given 64 or 128 10-sec shocks were impaired in terms of escape frequency. However, all groups given at least 64 shocks exhibited depressed intertrial responding at the 24-h, but not the 168-h, interval. In the final phase (Test Days 2–4), the control procedure for equalizing test-shock exposure was discontinued and a pattern of interference effects was observed in terms of escape-avoidance response latency that was identical to that reported for the escape frequency in Phase 2. In general, these data were viewed as indicating that duration, but not total amount of shock, was a critical determinant of behavior during inescapable shock and of the subsequent interference effect. Both effects of duration were regarded as the product of a common associative process involving the learning of immobility tendencies to shock that served to compete with later escape-avoidance responding.  相似文献

Using the conceptual model of reasoned action, one would expect that what teachers do with instructional materials would be influenced by their internal beliefs and their external constraints. In this two-year study with elementary teachers, using a supplemental science instructional resource,Superscience, it was found that teachers' internal beliefs about what will benefit their students are linked to the external constraints of their students' interests and the expected curriculum. Even if the teachers believed that the content of the resource would be helpful, they were not likely to use it if they believed it did not fit the expected curriculum.  相似文献

We argue that Garrett and Segall’s concepts of ‘doing school’ and ‘pushing back’ are valuable tools for analysing pre-service teachers’ political views of neoliberal education reforms such as the introduction of charter schools. We extend Garrett and Segall’s conceptualization by hybridizing ‘doing school’ and ‘pushing back’ in order to move beyond a simplistic celebration of student resistance, which often overlooks forms of resistance that are compliant with the status quo, in this case the neoliberal status quo. We analyse participants’ political views as they emerged in a debate about charter schools in New Zealand. Garrett and Segall’s concepts, in conjunction with poststructuralist theories of subjectivity, are deployed as analytical tools for understanding the complexity of students’ political subjectivities in a debate conducted on a Facebook page set up for that purpose.  相似文献

It has been claimed that the visual component of audiovisual media dominates young children's cognitive processing. This experiment examines the effects of input modality while controlling the complexity of the visual and auditory content and while varying the comprehension task (recall vs. reconstruction). 4- and 7-year-olds were presented brief stories through either audio or audiovisual media. The audio version consisted of narrated character actions and character utterances. The narrated actions were matched to the utterances on the basis of length and propositional complexity. The audiovisual version depicted the actions visually by means of stop animation instead of by auditory narrative statements. The character utterances were the same in both versions. Audiovisual input produced superior performance on explicit information in the 4-year-olds and produced more inferences at both ages. Because performance on utterances was superior in the audiovisual condition as compared to the audio condition, there was no evidence that visual input inhibits processing of auditory information. Actions were more likely to be produced by the younger children than utterances, regardless of input medium, indicating that prior findings of visual dominance may have been due to the salience of narrative action. Reconstruction, as compared to recall, produced superior depiction of actions at both ages as well as more constrained relevant inferences and narrative conventions.  相似文献

OBJECTIVE: This study explored the main and interactive effects of sexual abuse history and relationship satisfaction on self-reported parenting, controlling for histories of physical abuse and parental alcoholism. METHOD: The community sample consisted of 90 mothers of 5- to 8-year-old children. The sample was limited to those mothers currently in an intimate relationship, 19 of whom reported a history of childhood sexual abuse. Participants completed the Child Behavior Checklist, the Parenting Stress Inventory, the Family Cohesion Index, and questions assessing parent-child role reversal, history of abuse and parental alcoholism, and current relationship satisfaction. RESULTS: Results of analyses and multivariate analyses of covariance suggested that sexual abuse survivors with an unsatisfactory intimate relationship were more likely than either sexual abuse survivors with a satisfactory relationship or nonabused women to endorse items on a questionnaire of role reversal (defined as emotional overdependence upon one's child). Role reversal was not significantly predicted by histories of physical abuse or parental alcoholism or child's gender. While parenting stress was inversely predicted by the significant main effect of relationship satisfaction, neither parenting stress nor child behavior problems were predicted by the main effect of sexual abuse history or by the interaction between sexual abuse history and relationship satisfaction. CONCLUSIONS: These results suggest the unique relevance of sexual abuse history and relationship satisfaction in the prediction of a specific type of parent-child role reversal--namely, a mother's emotional overdependence upon her child.  相似文献
