In two experiments using a radial-arm maze, pairs of rats made choices among eight maze locations, each containing a large
quantity of one of two food types. The choices made by 1 rat affected the choices made by the other rat. Under most conditions,
visits by 1 rat increased the tendency of the other rat to subsequently choose that maze location. However, the effect depended
on the quality of the food available in a particular location. When it was possible for the rats to observe each other on
the maze arms and a rat had experienced that a location contained the less preferred food type, a previous visit to that location
by the foraging partner decreased the tendency to visit that location. These effects are attributed to working memory for
the spatial choices of another rat, and they indicate that memory produced by a rat’s own visit to a maze location is integrated
with memory for the behavior of another rat to determine spatial choice 相似文献

ObjectiveThe present study aimed to assess the mental and physical health of children held within a British immigration detention center.MethodA total of 24 detained children (aged 3 months to 17 years) were assessed with their parents or carer after being referred by a registered legal charity. Thirteen were seen by a pediatrician alone, 4 by a psychologist alone, and 7 by both professions using semi-structured clinical interviews. The psychologist also used standardized self-report questionnaires to measure psychopathology.ResultsDuring the psychological assessment of 11 children, 8 met criteria for psychiatric “caseness” on the Strengths and Difficulties Questionnaire. All 11 reported symptoms of depression and anxiety. Sleep problems, somatic complaints, poor appetite, emotional symptoms, and behavioral difficulties were common. Symptoms of global distress were also reported by all 9 parents. According to pediatric assessment 8 out of 20 children had lost weight. Six had missed health appointments and 2 were taken to hospital. Nutritional, developmental, educational, and child protection concerns were raised.ConclusionsDetained children were found to be experiencing mental and physical health difficulties of recent onset, which appeared to be related to the detention experience. These findings support previous Australian studies demonstrating that detention is not in the best interest of the child. It suggests that current UK policies regarding the detention of children for purposes of immigration control should be re-examined. Further research in the area is required.Practice implicationsAlthough high levels of mental and physical health problems, as well as child protection concerns were detected, detained families had very limited access to appropriate assessment, support or treatment. The traumatic experience of detention itself also has implications for the sizeable proportion of psychologically distressed children who are eventually released from detention and expected to successfully reintegrate into British society; while those children who are deported are returned with increased vulnerability to future stressors. 相似文献

This article analyzes the distribution of mathematics achievement among class, school, municipality, and state in Argentina. Data from the Year 2000, 6th-grade Primary School Census from the Minister of Education are analyzed using multilevel methodology. The results indicate that all levels of the education system are relevant and must be considered. If all levels are included, the school “raw” effect is much less (18%) than if they are not (31%). Prior academic performance and socioeconomic level of the individual pupil, plus socioeconomic composition variables, accounted for most of the performance distribution among school, municipality, and state levels. These kinds of variables do not explain significant inter-class differences inside the school. As a consequence, the class became the superior level with the larger proportion of the total unexplained variance (15%), while the school variation represents just 8,6% of that variation. Finally, unexplained inter-school and inter-class variation is still significant making it necessary to further investigate relevant schooling and classroom factors. 相似文献
