This paper presents research findings on childrens’ responses to migratory separation and later reunion in Caribbean families and the needs of these families when parents migrate and leave their children behind. Implications of this type of separation on children, parents and surrogate caregivers are discussed. The challenges that counsellors in both the ‘sending’ and host countries face working with this population are also examined and suggestions made for psychosocial intervention and guidelines for counselling in both societies. The need for culturally competent counsellors to work with the growing population of immigrants in North America and Europe is indicated.  相似文献

A multilevel modeling approach was employed to investigate the relation between sex composition and developmental change in 70 urban preschool classrooms. The research represents a unique contribution as (1) few studies have examined the influence of sex composition during the preschool years, (2) it represents the first research to use a continuous (i.e., sex ratio) as opposed to binary (i.e., mixed- versus single-sex) indicator for classroom sex composition, and (3) the sample represents an important and often neglected group (i.e., low-income children from urban schools). A series of HLM models were run, addressing the nested nature of the data (children within classrooms), and relating classroom sex composition to developmental change using the cognitive, motor, and social subscales from the Child Observation Record (COR). Overall, there were no main effects at the classroom-level for sex composition. However, a cross-level interaction indicated that, while girls’ development was not influenced by classroom sex composition, boys in classrooms with proportionally more boys fared significantly worse in terms of development as assessed by combined score on the COR. More specifically, this interaction was significant when predicting the COR cognitive subscale, but nonsignificant when predicting the COR social and motor subscales. This was true when controlling for the number of students at the classroom-level, as well as child's age and baseline ability (i.e., Time 1 COR) at the child-level. Implications for early childhood education policy are discussed.  相似文献

Children often judge that strange and improbable events are impossible, but the mechanisms behind their reasoning remain unclear. This article (N = 250) provides evidence that young children use a similarity heuristic that compares potential events to similar known events to determine whether events are possible. Experiment 1 shows that 5- to 6-year-olds who hear about improbable events go on to judge that similar improbable events can happen. Experiment 2 shows that 5- to 6-year-olds more often affirm that improbable events can happen if told about related improbable events than if told about unrelated ones. Finally, Experiment 3 shows that 5- to 6-year-olds affirm the possibility of improbable events related to known events, but deny that related impossible events can happen.  相似文献

The present experiment investigated the effects of kinship and familiarity upon food sharing in pairs of albino rat pups. Five pairs of rats from each of the following groups were tested: (1) familiar siblings, (2) nonfamiliar siblings, (3) familiar nonsiblings, and (4) nonfamiliar non-siblings. A small food portion was used, necessitating not only close physical contact, but also cooperation in the sense that both pups were required to remain relatively immobile in order for both to feed simultaneously. Results indicated more frequent sharing among unfamiliar pups, whether related or not. Results also indicated that food sharing increased in frequency among all four groups over the 5-day testing period, suggesting that cooperation in the form of food sharing can develop, or increase in frequency, over time in albino rat pups.  相似文献

Children's Comparisons of the Recency of Two Events from the Past Year   总被引:1,自引:0,他引:1  
Research on memory for time has been limited by the difficulty of disentangling several of the fundamentally different processes that contribute to a chronological sense of the past. This study used a developmental approach to isolate one of these processes, impressions of distances in the past. Large samples of children between 3 and 12 years were asked to judge which was longer ago, their birthday or Christmas (and, in one study, Halloween and Thanksgiving). Even children under 6 years of age were able to discriminate the recency of their birthday and Christmas with great accuracy when the events were widely separated and one was within the past several months. The ability to discriminate recency on these scales appears to be a basic property of human memory that changes little with development. Other information about the locations of the events and their relative times of occurrence could only be interpreted correctly by children older than 9 years.  相似文献

In this study, researchers compared the concordance of teacher-level effectiveness ratings derived via six common generalized value-added model (VAM) approaches including a (1) student growth percentile (SGP) model, (2) value-added linear regression model (VALRM), (3) value-added hierarchical linear model (VAHLM), (4) simple difference (gain) score model, (5) rubric-based performance level (growth) model, and (6) simple criterion (percent passing) model. The study sample included fourth to sixth grade teachers employed in a large, suburban school district who taught the same sets of students, at the same time, and for whom a consistent set of achievement measures and background variables were available. Findings indicate that ratings significantly and substantively differed depending upon the methodological approach used. Findings, accordingly, bring into question the validity of the inferences based on such estimates, especially when high-stakes decisions are made about teachers as based on estimates measured via different, albeit popular methods across different school districts and states.  相似文献

Previous research on adults' and children's memory for the time of past events has generally overlooked the fundamental distinction between knowledge of temporal distance in the past and knowledge of temporal locations. This study applied the distinction to the development of time memory. Children of 4, 6, and 8 years of age experienced 2 target events, one 7 weeks and the other 1 week before testing. They were asked to judge the relative recency of the 2 events and to localize the older event by time of day, day of the week, month, and season. Even the 4-year-olds were successful in judging the relative recency of the 2 events and localizing the older event by time of day. However, on the 3 longer time scales, only the 6- and 8-year-olds could localize the older event, reason about possible times that it could have occurred, or tell the present time. The great accuracy of the time-of-day judgments at all 3 ages is almost certainly not due to distance-type information. The results show the separate development of distance and location judgments.  相似文献

The development of children's knowledge of temporal structure   总被引:1,自引:0,他引:1  
Adults have a rich understanding of a number of time systems, but little is known about how this knowledge develops. 3 experiments were conducted to test a model in which the first representations of the days of the week and months of the year have verbal-list properties, and these are later supplemented by image representations. In Experiments 1 and 2, fourth or fifth graders could judge forward relative order for these contents, but not until adolescence could backward order judgments be made accurately. In Experiment 3, fourth graders used a serial process to solve a categorical distance judgment task, whereas older groups shifted to a process with more rapid access to information about the position of remote items. The results are interpreted as supporting the 2-stage model and appear inconsistent with a number of alternative models.  相似文献

The hypothesis that aggressive-rejected children are unaware of their social status because they are self-protective when processing negative peer feedback was tested in 3 studies. In Study 1, fourth-grade girls and boys were asked to name peers they liked or disliked, as well as peers they thought liked or disliked them. Comparisons of aggressive-rejected, nonaggressive-rejected, and average status groups revealed that aggressive-rejected children were more unrealistic in their assessments of their social status than were nonaggressive-rejected children. In Study 2, rejected and average boys identified in Study 1 were asked to name who they thought liked or disliked other children from their classroom. Comparisons of perceived and actual nominations for peers revealed that aggressive-rejected children were able to assess the social status of others as well as did nonaggressive-rejected and average status children. Because the difficulties aggressive-rejected children demonstrated in Study 1 did not generalize to judging the status of others in Study 2, the self-protective hypothesis was supported. Study 3 provided a parallel test of this hypothesis under more controlled conditions. Subjects from Study 2 viewed other children receiving rejection feedback from peers in videotaped interactions and received similar feedback themselves from experimental confederates. While all subjects rated self-directed feedback somewhat more positively than other-directed feedback, aggressive-rejected subjects had the largest self-favoring discrepancy between their judgments of self- and other-directed feedback. These findings also suggest that aggressive-rejected children may make self-protective "errors" when judging other children's negative feelings about them. Ethnicity differences in evaluating peer feedback emerged in Studies 1 and 3, raising questions about the impact of minority status on children's evaluations of rejection feedback.  相似文献
