学习困难儿童的元记忆监测与控制特点 总被引:13,自引:2,他引:11
以有无意义联系的两种中文词对为材料,采用2×3×2混合实验设计,对小学三到五年级学习困难儿童的元记忆监测、控制水平与学优儿童之间的差异及其发展特点进行研究。结果表明:1.学习困难儿童在三种元记忆监测判断等级上均显著低于学优儿童。2.学习困难儿童具有元记忆控制能力,但其控制水平相对低于学优儿童。3.学习困难儿童的元记忆监测判断和学习时间分配之间存在交互影响。4.学习困难儿童的元记忆监测和控制水平存在较为复杂的发展特点。据此得出结论认为,学习困难儿童的元记忆监测与控制能力都比学优儿童差,同时也表现出一定的发展趋势。 相似文献

关系-表征复杂性模型的检验 总被引:20,自引:0,他引:20
目前有关问题难度的观点多是不全面的,在综合前人研究的基础上提出了关系-表征复杂性模型。在该模型里,区分了问题难度和问题解决难度两个概念,二者的本质分别是关系复杂性和表征复杂性;关系复杂性包括水平复杂性和等级复杂性,表征复杂性相应地包括表征广度和表征深度。以172名小学高年级学生为被试,以长方形面积问题方面的三种测验收集的数据对该模型的内部和外部效度进行了检验,结果表明它能够有效解释问题(解决)难度,区分优、中、差三类学生所能达到的表征复杂性。这说明该模型有理论价值 相似文献

This paper discusses the psychological and physiological correlates of inner-city violence on children, and the potential mediating and moderating roles of parents. Data are based on interviews regarding exposure to community violence (ECV), parenting practices, child distress, posttraumatic symptomology, and competence. Cardiovascular activation was also measured. Community violence exposure related to distress, posttraumatic symptomology, and incompetence. Harsh parenting related to aggression, distress, incompetence, and higher heart rates. Parenting moderated but did not mediate the effects of violence on measures of competence. High violence plus harsh parenting predicted lower levels of systolic (SBP) and diastolic blood pressure (DBP). Results are discussed within an ecological framework of parent–child relations and as they relate to the conclusion that children undergoing dual levels of stress may experience a dissociative response. 相似文献

Normic Laws and the Significance of Nonmonotonic Reasoning for Philosophy of Science. Normic laws have the form ‘if A then normally B’. They have been discovered in the explanation debate, but were considered
as empirically vacuous (§1). I argue that the prototypical (or ideal) normality of normic laws implies statistical normality
(§2), whence normic laws have empirical content. In §3–4 I explain why reasoning from normic laws is nonmonotonic, and why
the understanding of the individual case is so important here. After sketching some foundations of nonmonotonic reasoning
as developed by AI-researchers (§5), Iargue that normic laws are also the best way to understand ceteris paribus laws (§6).
§7 deals with the difference between physical and non-physical disciplines and §9 with the difference between normicity and
approximation. In §8 it is shown how nonmonotonic reasoning provides a new understanding of the protection of theories against
falsification by auxiliary hypotheses. §10, finally, gives a system- and evolution-theoretical explanation of the deeper reason
for the omnipresence of normic laws in practice and science, and forthe connection between ideal and statistical normality.

Five Minute Speech Sample Expressed Emotion (FMSS-EE) was examined in families of youth with depressive disorders, nondepressed youth with attention deficit/hyperactivity disorder (ADHD), and community controls screened for the absence of depression and ADHD. Consistent with the hypothesis that FMSS-EE shows some specificity as a risk factor for depression, rates of critical EE were significantly higher among mothers of youth with depression as compared to mothers of nondepressed youth with ADHD, or mothers of controls. When both mothers' and fathers' scores were used to generate family EE ratings, rates of overall EE and critical EE were significantly higher for the depressed group than the control group, but the nondepressed ADHD group did not differ significantly from the other groups. Results support the hypothesis that critical EE in mothers shows some specificity as a risk factor or correlate of depression in youth. 相似文献

应对量表(COPE)测评维度结构研究 总被引:25,自引:3,他引:22
该文旨在对应对量表(COPE)的测评维度结构进行进一步的鉴别分析和验证研究。研究一对736名大学生的应对量表中文修订本(C-COPE)测评数据进行探索性二阶因素分析;研究二根据已有研究关于应对量表测评维度组构模式的不同结论,以及研究一的结果,提出十个假设模型,采用验证性因素分析测试这些模型与另一大学生样本(N:465)测评数据的拟合度。研究结果支持C-COPE八因子斜交模型。该量表如何进一步修订也在文中予以讨论。 相似文献

This paper reviews and discusses the results of five cross-cultural studies in Colombia, Costa Rica, El Salvador, Spain, and USA, using 2 (college students vs. their parents) × 2 (males vs. females) MANOVA match group designs with the Attitudes and Beliefs Inventory subscales as dependent variables, two multicultural studies investigating the relationship between some demographic variables (Pan American Health Organization's Index of Violence, and Acculturation) and people's Irrationality, and two multidisciplinary studies on the relationship between some medical conditions (skin diseases, and severity of symptoms during menopause) and Irrational Beliefs. 相似文献

This study presents initial data validating the use of a new instrument, the Impact of Traumatic Stressors Interview Schedule (ITSIS), to assess the occurrence of cancer-related posttraumatic stress in childhood cancer survivors and their mothers. Sixty-six child/adolescent cancer survivors and 64 of their mothers, as well as 130 young adult survivors, completed the ITSIS and other measures of posttraumatic stress and general distress. Five ITSIS factors were identified for the mothers and for the young adult survivors, and three ITSIS factors were identified for the child/adolescent survivors. Factors in all three samples reflected symptoms of posttraumatic distress, concern over medical late effects, communication, and changes in self due to cancer. Only young adult survivors had a factor reflecting a positive engagement with the cancer history. Factors correlated with validation measures in predicted ways. The findings further the conceptualization of posttraumatic stress in pediatric cancer by describing the traumatic experience for survivors and mothers. Comparing factors across samples allows an examination of different influences of cancer within families and over the course of development. 相似文献
