The present research investigated memory vulnerability to distortions. Different
encoding strategies were used when categorized lists were studied. The authors
assumed that an imagery strategy would be responsible for decreasing false
memories more than a word-whispering strategy, which is consistent with the
model of semantic access and previous research in the Deese-Roediger-McDermott
paradigm (the DRM paradigm; Deese, 1959;
Roediger & McDermott, 1995). A
normative study of category lists and 4 experiments were conducted to verify the
memory vulnerability to different encoding strategies (imagery, word-whispering,
control). Half of subjects recalled and half recognized previously studied
words. The results revealed a marked reduction in false recognition and recall
after imagery encoding, relative to after word-whispering encoding. 相似文献

提取练习比建构概念图更有利于记忆保持和迁移的研究结果尚存在争议。依据认知负荷的3个成分,设计两个实验探究前期知识水平与策略复杂性对以上两种学习策略有效性的影响。结果表明:(1)前期知识水平的主效应不显著,但是与学习策略之间存在交互作用:在提取练习策略条件下,高前期知识水平的被试与低前期知识水平的被试在记忆保持和迁移上的正确率没有显著差异,但是在建构概念图策略条件下,高前期知识水平的被试在记忆保持和迁移上的正确率显著地高于低前期知识水平的被试;(2)当降低概念图的难度后,被试使用建构部分概念图策略产生的认知负荷与使用提取练习策略相比显著降低,并且其在学习阶段学习到的知识量显著地高于使用提取练习策略的结果,但是在最终测试上,其记忆保持与迁移的正确率与使用提取练习策略并没有显著差异,策略的复杂性增加了学习者的额外负荷,但是对策略有效性的发挥却不具有决定性影响。以上结果说明提取练习策略之所以比建构概念图策略更具优势,不是因为其策略本身更易掌握,而是因为其与建构概念图策略相比不受学习者前期知识水平的影响。这意味着认知负荷理论可以很好地解释提取练习在记忆保持与迁移中产生优势效应的内部机制,并进一步证实提取练习与精细编码不同,具有独特的加工机制。 相似文献

Data gathered over the course of an 18‐year longitudinal study of 1025 New Zealand children were used to: (a) develop a profile of the maternal, child, and contextual factors associated with differing levels of exposure to maternal physical punishment, and (b) identify the key predictors of maternal physical punishment as reported by young people at age 18. Results revealed the presence of clear linear associations between the extent of young people's reported exposure to physical punishment and a wide range of maternal, child, and contextual factors. The key predictors of physical punishment suggested that the psychosocial profile of those mothers at greatest risk of physically punishing or mistreating their child was that of a young woman with a personal history of strict parenting who entered motherhood at an early age, and who was attempting to parent a behaviourally difficult child within a dysfunctional family environment characterized by elevated rates of inter‐parental violence and childhood sexual abuse. These findings were consistent with a cumulative risk factor model in which increasing risk factor exposure is associated with increasing levels of child physical punishment/maltreatment.

The phenotypic and genetic factor structure of performance on five Multidimensional Aptitude Battery (MAB) subtests and one Wechsler Adult Intelligence Scale—Revised (WAIS-R) subtest was explored in 390 adolescent twin pairs (184 monozygotic [MZ]; 206 dizygotic (DZ)). The temporal stability of these measures was derived from a subsample of 49 twin pairs, with test–retest correlations ranging from .67 to .85. A phenotypic factor model, in which performance and verbal factors were correlated, provided a good fit to the data. Genetic modeling was based on the phenotypic factor structure, but also took into account the additive genetic (A), common environmental (C), and unique environmental (E) parameters derived from a fully saturated ACE model. The best fitting model was characterized by a genetic correlated two-factor structure with specific effects, a general common environmental factor, and overlapping unique environmental effects. Results are compared to multivariate genetic models reported in children and adults, with the most notable difference being the growing importance of common genes influencing diverse abilities in adolescence. 相似文献

A successful school-to-work transition is a precursor of promising career development. In the present longitudinal study we investigated whether academic self-efficacy beliefs and grades in school at the ages of 12-15 would be associated with unemployment and job satisfaction at the age of 21. We found that individuals with high self-efficacy beliefs and better grades were less likely to become unemployed and more likely to be satisfied with their jobs. The relationship between high self-efficacy and unemployment was mediated by higher career-related motivation and by less perceived application stress, measured at the time of vocational training at the age of 18. The relationship between self-efficacy and job satisfaction was primarily mediated by higher vocational congruence and less application stress. We conclude that school-based interventions targeted at increasing academic capabilities and self-efficacy would help prepare adolescents for a successful school-to-work transition. 相似文献

Although creativity is an important aspect of occupational therapy theory and practice, there have been few studies that would explore this concept in the context of the occupational therapy process. This was the first qualitative study of creativity in occupational therapy in Slovenia. It was conducted as part of a larger mixed-methods study and included 22 experienced occupational therapists who participated in four focus groups. The focus of the study was on the exploration of different factors that could contribute to creativity and creative strategies in occupational therapy, in either a positive or a negative way. Since occupational therapy promotes a client-centered therapy approach, the role of the client as the motivating factor was of particular interest to our study. Six factors that can influence the creativity of occupational therapists emerged from the qualitative analysis (Strauss & Corbin, 1990). While the client was identified as the key factor, the potential of other factors was also recognized. This qualitative study increased the understanding of the concept of creativity and creative behavior in occupational therapy, and also provided empirical material that formed the basis for the development of a questionnaire on creativity in occupational therapy. 相似文献

儿童对图画喻意理解的比较研究 总被引:1,自引:0,他引:1
本文针对儿童对图画中隐喻情绪的识辨和理解的发展特点 ,进行了跨文化研究。旨在探索儿童对图画喻意的敏感性的发展规律以及不同教育方式对儿童图画认知发展的影响。 3 60名 4岁到 2 0岁的中英被试参加了实验。结果表明 :在识辨作品任务及口头评价中 ,中国儿童比英国同龄儿童更早理解图画的情绪喻意 ,并很少对图画的悲伤喻意持忽略态度。提示不同文化背景下 ,儿童对图画喻意的理解存在发展上的不均衡性 ,中国的幼教方式也许促进了儿童对图画喻意理解的发展。 相似文献
