Honeybees foraged from six locations, each of which was baited with sugar solution prior to each experimental trial. Under a variety of conditions, bees exhibited a small but reliable tendency to avoid revisits to locations that they had visited earlier during the experimental trial. These results replicate those of Brown and Demas (1994), who concluded that bees use working memory to discriminate previously visited locations from those not yet visited. The present experiments included procedures that allowed alternatives to this explanation to be more completely ruled out. The extent of spatial working memory performance exhibited by honeybees in these experiments appears to be limited by a process other than working memory capacity, perhaps the ability of bees to discriminate among several locations in close proximity to one another.  相似文献

This paper outlines the work of the Basildon Marital/Family Violence Project set up as a result of two studies undertaken by the National Society for the Prevention of Cruelty to Children (N.S.P.C.C.) School of Social Work, which looked at the effect of marital violence upon the children involved. These effects were classified under the following headings: (1) the children were scapegoated; (2) used as pawns in the marital battles; (3) turned agression against themselves; (4) had relationship problems at school; (5) were physically assaulted by the parents in 25% of the cases. The project, which is now in its 4th year, has offered social work services, consultation, training courses and research. Work with the families, and particularly with the children, has further emphasised the severe emotional damage that marital violence can have upon the children. The paper optimistically reports that after intensive work using a five-point treatment programme, and direct work with the children, there has been considerable diminution of violence in many of the cases and in some cases no repetition of such violence at all. The worker's approach, it is suggested, should be characterised by optimism combined with indestructible calm, genuine empathy combined with 24-hour access, persistence in the face of lack of progress, enhancement of parents' low self-esteem, regular contact and an ability to contain destructiveness.  相似文献

Attachment and Adolescent Psychosocial Functioning   总被引:9,自引:1,他引:8  
To explore the meaning and function of attachment organization during adolescence, its relation to multiple domains of psychosocial functioning was examined in a sample of 131 moderately at-risk adolescents. Attachment organization was assessed using the Adult Attachment Interview; multiple measures of functioning were obtained from parents, adolescents, and their peers. Security displayed in adolescents' organization of discourse about attachment experiences was related to competence with peers (as reported by peers), lower levels of internalizing behaviors (as reported by adolescents), and lower levels of deviant behavior (as reported by peers and by mothers). Preoccupation with attachment experiences, seen in angry or diffuse and unfocused discussion of attachment experiences, was linked to higher levels of both internalizing and deviant behaviors. These relations generally remained even when other attachment-related constructs that had been previously related to adolescent functioning were covaried in analyses. Results are interpreted as suggesting an important role for attachment organization in a wide array of aspects of adolescent psychosocial development.  相似文献

This study investigated how teachers used an electronic performance support system (EPSS) and whether the usage of this EPSS affected their work performance and attitudes toward computer technology. The findings suggested a framework for the implementation of an EPPS in an educational setting, specifically at a middle school. The data were collected through observations, questionnaires, anecdotal logs, database records, and interviews. Four middle school teachers used the EPSS primarily for completing student progress reports wherein the results indicated that the EPSS decreased the amount of time to perform this task. Computer usage, performance, and attitudes were affected by work responsibilities, accessibility to computers, the change agent, the technology support personnel, as well as the specific characteristics of the EPSS. The teachers' attitudes toward the EPSS and technology in general were affected by their performances when using the system, by interactions with the person responsible for technology support, and by the ability to customize the computer program to fit their needs.  相似文献

National longitudinal databases hold much promise for school counseling researchers. Several of the more frequently used data sets, possible professional implications, and strategies for acquiring training in the use of large‐scale national data sets are described. A 6‐step process for conducting research with the data sets is explicated: determining research questions, accessing the data set, understanding the study's sample design, determining an analytic sample, considering pertinent data analysis issues, and understanding the limitations of using the data sets. Suggestions for preparing school counseling researchers and potential themes for future research are outlined.  相似文献

Contingent self-esteem (CSE) describes the degree to which self-esteem is dependent on meeting day-to-day appraisals from oneself and others. This will vary between individuals, ranging from lower to higher CSE. A lower CSE is related to a range of adaptive social and emotional outcomes in adolescents and young adults. This study explores children’s CSE and how this associates with behavioural outcomes. A total of 280 children between the ages of 9 and 11 years completed a composite questionnaire on aspects of their self-esteem and behaviour. Children’s class teachers completed behavioural outcome questionnaires for a random sample of 100 of these children. Based on teachers’ and children’s scores, high levels of global self-esteem were associated with lower CSE and fewer behavioural difficulties. CSE domains of social feedback and physical appearance retained significant associations with behavioural outcomes after controlling for global self-esteem. This may relate to the degree that children depend on the perceived evaluations of others. Implications for educational psychologists are highlighted.  相似文献
