为探讨同伴地位影响青少年冒险行为的作用机制及条件,采用青少年冒险行为问卷、同伴提名问卷、自我控制能力问卷、同伴群体特征问卷对山东省日照市1288名初高中学生进行调查。结果发现,(1)同伴地位负向预测青少年冒险行为,该预测作用是通过交往不良同伴的中介作用实现的;(2)交往不良同伴对青少年冒险行为的预测受到个体自我控制能力的调节。对于高自我控制能力青少年,其冒险行为与交往不良同伴无关,但低自我控制能力青少年会因交往不良同伴而参与更多冒险行为。结果提示培养良好的自我素质,塑造良好的同伴环境对于青少年的健康发展有重要作用。  相似文献

Abstract

The main approach to rectifying the well documented poor basic life support (BLS) skills of doctors and nurses, based on a Skills Model, has met with only partial success. This study compares the utility of a Skills Model with one that incorporates a cognitive component in predicting BLS skills. Outcome-expectancy, self-efficacy, training and experience of BLS, and BLS ability were assessed in 53 trained nurses. Ability was unrelated to training or experience of BLS. Nurses who scored highest on the BLS skills assessment perceived the procedure as significantly more successful than those with lower scores. Self-efficacy was unrelated to ability, but was related to status: senior nurses were significantly more confident but no more competent in performing BLS than junior nurses. Nurses who had attended more arrests, while more confident, were no more competent than those who had attended fewer. Assessment of BLS skills reduced self-efficacy beliefs. A model for predicting the relationship between self-assessed ability and objectively assessed skill is outlined.  相似文献

Possible links between phonological short-term memory and both longer term memory and learning in 8-year-old children were investigated in this study. Performance on a range of tests of long-term memory and learning was compared for a group of 16 children with poor phonological short-term memory skills and a comparison group of children of the same age with matched nonverbal reasoning abilities but memory scores in the average range. The low-phonological-memory group were impaired on longer term memory and learning tasks that taxed memory for arbitrary verbal material such as names and nonwords. However, the two groups performed at comparable levels on tasks requiring the retention of visuo-spatial information and of meaningful material and at carrying out prospective memory tasks in which the children were asked to carry out actions at a future point in time. The results are consistent with the view that poor short-term memory function impairs the longer term retention and ease of learning of novel verbal material.  相似文献

In this article, we report a new image-scanning paradigm that allowed us to measure objectively individual differences in spatial mental imagery—specifically, imagery for location. Participants were asked to determine whether an arrow was pointing at a dot using a visual mental image of an array of dots. The degree of precision required to discriminate “yes” from “no” trials was varied. In Experiment 1, the time to scan increasing distances, as well as the number of errors, increased when greater precision was required to make a judgement. The results in Experiment 2 replicated those results while controlling for possible biases. When greater precision is required, the accuracy of the spatial image becomes increasingly important—and hence the effect of precision in the task reflects the accuracy of the image. In Experiment 3, this measure was shown to be related to scores on the Paper Folding test, on the Paper Form Board test, and on the visuospatial items on Raven's Advanced Progressive Matrices—but not to scores on questionnaires measuring object–based mental imagery. Thus, we provide evidence that classical standardized spatial tests rely on spatial mental imagery but not object mental imagery.  相似文献

本研究以62名3~6岁儿童为被试,考察了幼儿在不同任务中对自身和他人能力判断的发展特点。结果表明:(1)幼儿对自身或他人能力判断的准确性随着年龄的增长而提高;(2)幼儿对他人能力判断并不比对自身能力判断更准确,随着年龄的增长,幼儿开始对自身能力做出更加积极的判断;(3)幼儿能够明确区分愿望与预期,不过当幼儿对自身能力进行判断时这种区分不容易显现出来。  相似文献

用创造力培养观、教学监控能力和创造性教学行为问卷对430名小学教师进行调查,考察三者之间的关系,并着重对教学监控能力在其中的中介作用进行分析。结果表明:(1)创造力培养观、教学监控能力及其各个维度对创造性教学行为都有正向预测作用;(2)教学监控能力的计划准备性、控制调节性、评价反馈性、课后反省性及作为一个整体在创造力培养观与创造性教学行为之间均具有显著的中介效应。这一发现提示教师培训工作应重视教师教学监控能力的实际增长,这样才能使教师已经接受的创造教育理念落实到创造性教学行为上。  相似文献

以西北民族地区甘南藏族自治州的1所多民族混合学校、1所单一少数民族学校以及兰州市1所普通中学的521名中学生为被试,采用心理地位量表和中学生人际交往能力问卷,探讨不同学校类型中学生心理地位和人际交往能力的关系。结果表明:(1)西北民族地区藏汉混合学校学生的心理地位显著高于单一民族中学的学生,但与普通中学的学生之间不存在显著差异;(2)西北民族地区藏汉混合学校学生人际交往能力得分显著高于单一民族中学的学生,但与普通中学学生之间差异不显著;(3)西北民族地区中学生的心理地位与人际交往能力之间存在显著相关;(4)西北民族地区中学生的心理地位特征能够较好地预测其人际交往能力的发展水平。  相似文献

Children who like to read and write tend to be better at it. This association is typically interpreted as enjoyment impacting engagement in literacy activities, which boosts literacy skills. We fitted direction-of-causation models to partial data of 3690 Finnish twins aged 12. Literacy skills were rated by the twins’ teachers and literacy enjoyment by the twins themselves. A bivariate twin model showed substantial genetic influences on literacy skills (70%) and literacy enjoyment (35%). In both skills and enjoyment, shared-environmental influences explained about 20% in each. The best-fitting direction-of-causation model showed that skills impacted enjoyment, while the influence in the other direction was zero. The genetic influences on skills influenced enjoyment, likely via the skills→enjoyment path. This indicates an active gene-environment correlation: children with an aptitude for good literacy skills are more likely to enjoy reading and seek out literacy activities. To a lesser extent, it was also the shared-environmental influences on children's skills that propagated to influence children's literacy enjoyment. Environmental influences that foster children's literacy skills (e.g., families and schools), also foster children's love for reading and writing. These findings underline the importance of nurturing children's literacy skills.

Highlights

  • It's known that how much children enjoy reading and writing and how good they are at it correlates ∼0.30, but causality remains unknown.
  • We tested the direction of causation in 3690 twins aged 12.
  • Literacy skills impacted literacy enjoyment, but not the other way around.
  • Genetics influence children's literacy skills and how much they like and choose to read and write, indicating genetic niche picking.

Abstract

The tall-poppy syndrome (TPS) is a pattern of behaviour whereby people who excel in some respect are cut down to size by those around them. People are often uncomfortable with those who excel and therefore, in effect, seek to put them in their place. I argue in this article that the TPS is, in some respects, getting worse, even in the creative professions. I suggest a number of reasons why this might be so and also what societies might do about it.  相似文献

计算机形式的测验能够记录考生在测验中的题目作答时间(Response Time, RT),作为一种重要的辅助信息来源,RT对于测验开发和管理具有重要的价值,特别是在计算机化自适应测验(Computerized Adaptive Testing, CAT)领域。本文简要介绍了RT在CAT选题方面应用并作以简评,分析了这些技术在实践中的可行性。最后,探讨了当前RT应用于CAT选题存在的问题以及可以进一步开展的研究方向。  相似文献
