Improbable or impossible? How children reason about the possibility of extraordinary events

The present study investigated the development of possibility-judgment strategies between the ages of 4 and 8. In Experiment 1, 48 children and 16 adults were asked whether a variety of extraordinary events could or could not occur in real life. Although children of all ages denied the possibility of events that adults also judged impossible, children frequently denied the possibility of events that adults judged improbable but not impossible. Three additional experiments varied the manner in which possibility judgments were elicited and confirmed the robustness of preschoolers' tendency to judge improbable events impossible. Overall, it is argued that children initially mistake their inability to imagine circumstances that would allow an event to occur for evidence that no such circumstances exist.     

Pointing at objects in other rooms: young children's sensitivity to perspective after walking with and without vision

Locomotion alters the spatial structure of an observer's perspective, that is, the network of observer to environment distances and directions. The purpose of the present 6 experiments was to investigate the sensitivity of 12-48-month-olds to changes in perspective that are occluded from view by walls and by darkness. To assess sensitivity, children were shown a target object in one room, walked into an adjacent room and asked to point in the straight-line direction at the target. In Experiment 1, 42 12-48-month-olds were tested and results indicated that children older than 36 months responded by pointing straight at the occluded target, whereas younger children tended to point in the direction of their route away from the target. In Experiments 2-4, 24- and 48-month-olds were tested and results demonstrated that 48-month-olds were sensitive to the proprioceptive and to the visual-environmental cues for the changes in perspective structure. The 24-month-olds, however, responded by pointing straight toward the target when visual-environmental cues were absent, whereas they pointed in the direction of their route when they were present. In Experiments 5 and 6 additional 24-month-olds were tested to assess the effects of short-term training and of a continuous view of the target on responding in the presence of visual-environmental cues. The results indicated relatively early sensitivity to proprioceptive cues for changes in perspective and somewhat later sensitivity to appropriate visual-environmental cues under these conditions.     

Exploring children’s perceptions of the perceived seriousness of disruptive classroom behaviours

Children’s reports of the perceived seriousness of disruptive classroom behaviours were examined from their own perspective and from their perceptions of their peers’ beliefs about the same behaviour. Two hundred and seventy-six (116 female and 161 male, M_age?=?11.00?years, SD_age?=?1.29) children recruited from a primary and a secondary school in the UK completed measures of the perceived seriousness of disruptive classroom behaviours from their own perspective and also their beliefs about their peers’ perceptions, social desirability and social behaviour. A three-factor structure of disruptive classroom behaviours emerged encompassing: Imprudent behaviours, negative behaviours and expressed emotions. Children judged the disruptive classroom behaviours as more serious compared to how they thought their peers would judge the same behaviour. Gender and age differences also emerged. The findings support the conclusion that children regard disruptive classroom behaviours as more serious than they believe their peers do.     

The Development of Distributive Justice Orientations: Contextual Influences on Children''s Resource Allocations

Previous research on the development of distributive justice decisions, by centering largely on situations in which rewards for work productivity are to be allocated, has shed little light on the child's developing ability to select the justice norm most appropriate to the situation. Children 5, 9, and 13 years of age were asked to allocate resources and judge the fairness of alternative decision rules in situations to which either equity, equality, or need norms were especially applicable. As predicted, young children were insensitive to contextual information, generally preferring to allocate resources equally, whereas older children tailored their decisions appropriately to the situation. The fact that developmental trends differed from situation to situation points to the importance of adopting a contextual perspective on the development of distributive justice orientations.     

"A burden in your heart": lessons of disclosure from female preadolescent and adolescent survivors of sexual abuse

OBJECTIVES: To enhance understanding of the sexual abuse disclosure process from the perspective of preteen and teenage survivors. To reconsider prominent models of the disclosure process in light of our findings. METHODS: We conducted a secondary analysis of data from four focus groups in which 34 preadolescent and adolescent female survivors of sexual abuse had been asked about their treatment experiences. Girls often recounted disclosing their victimization to others. Using the disclosure segment as our unit of analysis, we isolated 106 for study. During analysis, we wrote narrative summaries of each segment's significance, grouped these conceptually, and examined their interconnectedness. When synthesized, individual experiences of disclosing contributed to understanding the overall disclosure process. RESULTS: Three phases were identified: Self, where children come to understand victimization internally; Confidant Selection-Reaction, where they select a time, place, and person to tell and then weather that person's reaction (supportive or hostile); and Consequences (good and bad) that continued to inform their on-going strategies of telling. The actions and reactions of adults were significant and informed the girls' decisions. CONCLUSIONS: We advocate integrating existing theories and research into a model which views the disclosure process from the child's perspective and includes pre-disclosure and a post-initial public disclosure stages. The model conceptualizes disclosure as an iterative process in which children interact with adults and incorporate responses into their on-going decisions about telling (recant, deny, affirm, etc.). The combined model should recognize the concerns and position of adults as well as the perspective and logic of youth.     

Social Interactions in Preschool Classrooms and the Development of Young Children's Conceptions of the Personal

Two studies examined preschool teacher and child interactions regarding personal, moral, and social-conventional issues in the classroom and the development of personal concepts in young children. In Study 1, 20 preschool classrooms, 10 with 3-year-olds and 10 with 4-year-olds, were observed to assess children's and teachers' interactions regarding personal, moral, social-conventional, and mixed events. Teachers used more direct messages regarding moral and social-conventional events than personal and mixed events. Teachers offered children choices, but they rarely negotiated personal events with children. Children responded with personal choice assertions when adults offered them choices, but adults did not differ in the frequency that they negated or affirmed children's assertions of personal choice. In Study 2, 120 preschool children, nearly evenly divided between males and females at 3, 4, and 5 years of age, were interviewed regarding their conceptions of personal events in the classroom and home. With age, children judged that they should retain control over personal decisions in both contexts. In both judgments and social interactions, teachers and children identified a personal domain in which children can and should make choices about how to structure their activities and assert their independence in the classroom.     

Young Children Understand That Looking Leads to Knowing (So Long as They Are Looking into a Single Barrel)

3 experiments were conducted to investigate the claim made by Wimmer, Hogrefe, and Perner that 3-4-year-old children do not understand that people gain knowledge about something by looking at it. The first experiment involved a simple forced-choice procedure in which children had to judge which of 2 assistants knew what was inside a box when one of the assistants had looked inside and the other had lifted it up. In this experiment, the children did realize that the assistant who had looked in the box knew its contents. The second experiment followed the Wimmer et al. procedure, but with a simpler question form. The children were just asked to state whether someone knew what was in the box. Again, the children were able to work out that a person who had looked in a box knew what was inside it. In the third experiment, a direct comparison was made between the simpler question and the more complex, double-barreled question asked by Wimmer et al. The children found the more complex question considerably harder. The results of these experiments suggest that, in contrast to the claims made by Wimmer et al., 3- and 4-year-old children do understand that looking leads to knowing, and that their difficulty in the Wimmer et al. study was mainly with the form of the question that they were asked.     

Cochlear implants for younger children: a preliminary description of the parental decision process and outcomes

The authors conducted a preliminary telephone interview study of a random sample of 35 parents whose children had received cochlear implants through a large-scale implant program. Parents were asked about their child's preimplant and postimplant communications skills, how they learned about implants, and how they arrived at the decision to have their child receive an implant. Results of the interviews suggest, a least for this program, that two types of decision sequences are followed. One type of parent has initial and primary contact through a medical practitioner, uses that source of information exclusively, and is motivated by a desire for a "normal" communication situation. The second type of parent learns about implants from another parent, family member, or teacher. This individual will seek other sources of information and is most often motivated by the child's lack of communication skill. Generally, from parents' perspective, language and speech rather than improved social skills or social contact are the primary benefits of the implant.     

Children''s Understanding of Action Lines and the Static Representation of Speed of Locomotion

Children's understanding of the static representation of speed of locomotion was explored in 2 experiments. In Experiment 1, 20 7-year-olds and 20 9-year-olds drew pictures of 2 people walking and running at different speeds. Children then made judgments about pairs of unambiguous drawings of a person walking or running, as did a sample of 20 adults. The drawings varied according to whether action lines, background lines, or no lines were present. Children were asked to say which figure appeared to be moving faster. In Experiment 2, 20 7-year-olds, 20 9-year-olds, and 21 adults sorted ambiguous drawings of a person walking and running at different speeds. The pictures again contained action lines, background lines, or no lines. In the drawing task, children more frequently used page position and biomechanical information than action lines to represent fast and slow walking and running. In the judgment task, 7- and 9-year-olds offered equivalent judgments of action lines and background lines, whereas adults distinguished between these pictorial devices. In the sorting task, all subjects distinguished between action lines and background lines and judged that pictures containing action lines looked faster than pictures containing background lines and pictures without lines. Taken together, the results indicate that subjects' judgments were influenced by the form of locomotion and degree of ambiguity in the depicted events they saw. The findings are consistent with the view that different categories of pictorial devices exist, but the effectiveness of each device is contingent upon the perceiver's experience with it and the context in which it appears.     

It's All a Matter of Timing: Sign Visibility and Sign Reference in Deaf and Hearing Mothers of 18-Month-Old Children

The signed and spoken language produced by 14 mothers to their 18-month-old children during free play was analyzed. All the children had profound prelingual deafness. Seven of the mothers were profoundly deaf and fluent users of British Sign Language (BSL) or Auslan. The other seven were hearing and had enrolled in a signing program. Maternal signed utterances were classified according to whether they were made in the child's line of sight and whether they had a salient context; that is, they referred to an object or event at the child's current focus of attention. Spoken utterances were coded by word length. Comparisons between the two groups showed that both deaf and hearing mothers produced a majority of single-sign utterances (rather than utterances containing two or more signs). Deaf mothers also produced a majority of single-word spoken utterances, whereas the hearing mothers produced a significantly greater proportion of multiword utterances. As predicted, deaf mothers were more successful than hearing mothers in presenting signed utterances with a salient context that were visible to their children. Across the group as a whole, the total number of visible and salient signed utterances produced in 10 minutes was positively correlated with the total number of occasions on which mothers successfully redirected their child's attention or the child spontaneously turned to look at the mother. This suggests that deaf children who are visually attentive to their mothers receive a greater number of visible signed utterances with a salient context. I argue that this provides a more secure context for early language development.

Contexts of achievement: a study of American, Chinese, and Japanese children

The major purpose of this study was to attempt to understand some of the reasons for the high academic achievement of Chinese and Japanese children compared to American children. The study was conducted with first and fifth graders attending elementary schools in the Minneapolis metropolitan area, Taipei (Taiwan), and Sendai (Japan). 1,440 children (240 first graders and 240 fifth graders in each city) were selected as target subjects in the study. The children were selected from 20 classrooms at each grade in each city and constituted a representative sample of children from these classrooms. In a follow-up study, first graders were studied again when they were in the fifth grade. The children were tested with achievement tests in reading and mathematics constructed specifically for this study, the children and their mothers were interviewed, the children's teachers filled out a questionnaire, and interviews were held with the principals of the schools attended by the children. In the follow-up study, achievement tests were administered, and the children and their mothers were interviewed. Background information about the children's everyday lives revealed much greater attention to academic activities among Chinese and Japanese than among American children. Members of the three cultures differed significantly in terms of parents' interest in their child's academic achievement, involvement of the family in the child's education, standards and expectations of parents concerning their child's academic achievement, and parents' and children's beliefs about the relative influence of effort and ability on academic achievement. Whereas children's academic achievement did not appear to be a central concern of American mothers, Chinese and Japanese mothers viewed this as their child's most important pursuit. Once the child entered elementary school, Chinese and Japanese families mobilized themselves to assist the child and to provide an environment conducive to achievement. American mothers appeared to be less interested in their child's academic achievement than in the child's general cognitive development; they attempted to provide experiences that fostered cognitive growth rather than academic excellence. Chinese and Japanese mothers held higher standards for their children's achievement than American mothers and gave more realistic evaluations of their child's academic, cognitive, and personality characteristics. American mothers overestimated their child's abilities and expressed greater satisfaction with their child's accomplishments than the Chinese and Japanese mothers. In describing bases of children's academic achievement, Chinese and Japanese mothers stressed the importance of hard work to a greater degree than American mothers, and American mothers gave greater emphasis to innate ability than did Chinese and Japanese mothers.     

组织课堂教学的几点新思考

组织教学是课堂教学的重要组成部分,是保证教师上课正常有序进行和确保教学质量的一个基本条件。与教学方法和教学内容一样,教师如何"亮相"、如何使用声音、如何安排学生座位、如何对学生进行教学分组等同样值得对其进行深入的思考和分析。     

Building functional models: Designing an elbow

Previous work suggests that children largely perceive science as the passive observation and recording of events. In contrast, studies of practicing scientists show a concern with building and testing models. In this study we investigated the role of a design context for developing children's understanding of science as the construction and revision of models. Grade 1–2 children were given the task of building a model that works like a human elbow. Via discussion, model building, evaluation, and revision, children came to understand that not only motion but also constraints on motion were important qualities to include in their models. Moreover, review of classroom activity and analysis of the postmodeling interview suggest that as early as first grade, children's model-evaluation skills may be quite amenable to development: In comparison to a nonmodeling peer group, modelers were largely able to ignore perceptual qualities when asked to judge the functional qualities of models. Further, they showed an understanding of the modeling process in general that was similar to that of children 3–4 years older. © 1997 John Wiley & Sons, Inc. J Res Sci Teach 34 : 125–143, 1997.     

Early Constraints on the Imagination: The Realism of Young Children

The imagination of young children has notable constraints. The outcomes and possibilities that they imagine rarely deviate from the everyday regularities they have observed and remembered. Their reality-based imagination is evident in a variety of contexts: early pretend play, envisioning the future, judgments about what is possible, the instructive role of thought experiments, tool making, and figurative drawing. Overall, the evidence shows that children’s imagination helps them to anticipate reality and its close alternatives. This perspective invites future research on the scope of children's thinking about counterfactual possibilities, their ability to make discoveries about reality on the basis of thought experiments, and the ways in which cultural input can expand the scope of the possibilities that they entertain.     

Using Power and Caring to Mediate White Male Privilege,Equality, and Equity in an Urban Elementary Classroom: Implications for Teacher Preparation

Although students from diverse backgrounds may have access to equal educational opportunity by occupying the same classroom space, they do not necessarily enjoy equal and fair access to the same quality of experience within that classroom. The inequalities and inequities are partially a result of privilege, an advantage afforded to individuals because of their similarity to the norms operating in the classroom. In this article, the ways in which the white male students in a diverse, urban fourth grade classroom exercise privilege are identified and the white teacher's approach to mediating white male privilege, equality, and equity is examined. The teacher's approach is evaluated in terms of fairness via the white male students' perceptions of the classroom environment, viewed in relation to power and caring and is discussed with respect to implications for teacher preparation.     

Effects of Classroom Seating Arrangements on Children's question-asking

This study investigated the relationship between classroom seating arrangements and the question-asking of fourth-graders. Data were collected during 53 lessons spread over 8 weeks. Children were assigned to sit in a semicircle and then in a row-and-column seating arrangement for 2 weeks each. This rotation was repeated. Both children's questions and the teacher's verbal reactions were recorded using an observational system based on Kearsley's question taxonomy. The results showed that children asked more questions in the semicircle than in the row-and-column arrangement, and that the pattern of question characteristics was stable over time. The findings also revealed that, within the row-and-column arrangement, there was an action-zone in which children asked more questions per lesson. The results are interpreted in terms of Steinzor's postulation that social interaction is encouraged when individuals are able to establish face-to-face contact.

Beliefs about Children: A Comparative Study of Mothers, Teachers, Peers, and Self

This study was designed to clarify findings from the parents' beliefs literature concerning the nature and the effects of parental accuracy. Subjects were 60 second- and fifth-grade children (mean ages = 8–5 and 11–5, respectively), their mothers, and teachers. Each child responded to 4 cognitive tasks, predicted how he or she would perform on each task, made self-assessments of preferences and personality traits, and predicted the response of 2 peers to all of the measures. Both the child's mother and the child's teacher were shown the tasks and made similar predictions of the child's probable response. As in previous studies, mothers were above chance but far from perfect in predicting their children's cognitive performance and preferences and traits. Teachers were as accurate as mothers in judging cognitive abilities; they were less successful, however, on the preference and personality items. The children's predictions, whether for self or peers, were less accurate than those of the adults on all tasks. The accuracy of the mothers' predictions correlated positively with external measures of the child's cognitive performance. This finding is compatible with the Hunt "match hypothesis," although other bases for the correlations also exist.
