How Do Sibling Conflicts End?

The endings of sibling conflicts were investigated in 40 families at 2 time periods. Each family included 2 children, studied when they were 2 1/2 and 4 1/2 years of age, and 2 years later, at 4 1/2and 6 1/2 years. Four types of conflict endings were observed in sibling conflicts: Compromise, Reconciliation, Submission, and No Resolution. Results indicate that at both time periods conflicts typically ended with No Resolution, followed by Submission, Compromise, and finally, Reconciliation. Submissions decreased and No Resolutions increased over the two time periods; no changes were observed in either Compromise or Reconciliation. Parents' interventions led directly to a resolution of 16% of the children's disputes (Parent Ending). In those cases, there was a greater likelihood of conflicts ending in Compromise or Reconciliation than when parents did not intervene. Conflicts in which parents intervened but the children ultimately resolved the conflicts themselves (Child Ending with Intervention) occurred 42% of the time. Such conflicts ended more often with No Resolution and less often with children's Submissions to their siblings. The implications of these findings for the development of children's conflict resolution skills and the role of parent involvement are discussed.     

Early Relationship Quality From Home to School: A Longitudinal Study

The aim of this investigation was to examine the role of social relationships in the home as predictors of social functioning in the first years of school. Longitudinal data gathered on 156 children from urban, low-income families were used to examine the unique contributions of mother-child attachment classification at ages 1 and 2 years, the child's relationship with another adult caregiver, the child's closeness to a sibling, and the child's status in the family relative to siblings between ages 3 and 4 years, to teacher reports of their own relationship to the child and the child's social skills in the classroom and peer relations. The role of family-based relationships as possible protective factors for children at social or demographic risk for problems in school was also tested. Results indicate that quality of different family relationships provides relatively independent and complementary information about early social functioning in school, with more limited evidence for compensatory or protective processes at work.     

Pigeons’ memory for empty time intervals marked by visual or auditory stimuli

In Experiment 1, pigeons were trained to discriminate the duration (2 or 8 sec) of an empty interval separated by two 1325-Hz tone markers by responding to red and green comparison stimuli. During delay testing, a choose-short bias occurred at 1 sec, but a robust choose-long bias occurred at 9 sec. Responding in the absence of tone markers indicated that the pigeons were attending to the markers and not simply timing the total trial duration. The birds were then trained to match short (2-sec) or long (8-sec) empty intervals marked by light to blue/yellow comparisons. For both visual and auditory markers, delay testing produced a choose-short bias at 1 sec and a choose-long bias at 9 sec. In Experiment 2, the pigeons were shifted from a fixed to variable intertrial intervals (ITI) within sessions. On trials with tone markers, the duration of both the empty interval and the preceding ITI affected choice responding. On trials with light markers, only the duration of the empty interval influenced choice responding. Subsequent delay testing in the context of variable ITIs replicated the memory biases previously obtained. In Experiment 3, performance was assessed at various delay intervals on trials in which either the first or the second marker was omitted. The data from these omission tests indicated that the first marker initiated timing but that the second marker sometimes initiated the timing of a new interval. Explanations of these effects in terms of the internal clock model of timing are discussed, and a simple quantitative model of the delay interval data is tested.     

Finding without seeking: the information encounter in the context of reading for pleasure

This paper examines nongoal oriented transactions with texts in order to investigate the information encounter in the context of daily living. Findings are reported from a larger research project based on intensive interviews with 194 committed readers who read for pleasure. The paper analyses interview responses that illuminate two aspects of the readers' experience of reading for pleasure: (1) how readers choose books to read for pleasure; and (2) books that have made a significant difference in readers' lives. The paper concludes with five themes emerging from this analysis that have implications for the information search process: the active engagement of the reader/searcher in constructing meaning from texts; the role of the affective dimension; ‘trustworthiness’; the social context of information seeking; and the meta-knowledge used by experienced readers in making judgments about texts.     

The Me in Memory: The Role of the Self in Autobiographical Memory Development

This article tests the hypothesis that self-development plays a role in the offset of childhood amnesia; assessing the importance of both the capacity to anchor a memory to the self-concept, and the strength of the self-concept as an anchor. This research demonstrates for the first time that the volume of 3- to 6-year old's specific autobiographical memories is predicted by both the volume of their self-knowledge, and their capacity for self-source monitoring within self-referencing paradigms (N = 186). Moreover, there is a bidirectional relation between self and memory, such that autobiographical memory mediates the link between self-source monitoring and self-knowledge. These predictive relations suggest that the self-memory system is active in early childhood.     

Search on surfaces: Exploring the potential of interactive tabletops for collaborative search tasks

Collaborative information seeking often takes place in co-located settings; such opportunities may be planned (business colleagues meeting in a conference room or students working together in a library) or spontaneous (family members gathered in their living room or friends meeting at a café). Surface computing technologies (i.e., interactive tabletops) hold great potential for enhancing collaborative information seeking activities. Such devices provide engaging direct manipulation interactions, facilitate awareness of collaborators’ activities, and afford spatial organization of content. However, current tabletop technologies also present several challenges that creators of collaborative information seeking system must account for in their designs. In this article, we explore the design space for collaborative search systems on interactive tabletops, discussing the benefits and challenges of creating search applications for these devices. We discuss how features of our tabletop search prototypes TeamSearch, FourBySix Search, Cambiera, and WeSearch, illustrate different aspects of this design space.     

Model of affective learning for nonformal science education facilities

Objective setting and evaluation for learning in the affective domain are often neglected in educational programs, largely because affective learning is a poorly understood phenomenon. This is particularly problematic in nonformal science education facilities, which are uniquely suited to facilitate affective learning. To address this problem, a heuristic model of affective learning in nonformal educational facilities was developed. The model, referred to as the Meredith Model, displays a sequence of events occurring in the affective responses of learners in nonformal educational experiences and identifies factors which may influence individual events within this sequence. The model is proposed as a conceptual framework for gaining an increased understanding of affective learning and for making recommendations for practice of nonformal science education and for further research.
