成就目标定向、测验焦虑与工作记忆的关系   总被引:12,自引:0,他引:12  
在工作记忆广度测验情境下,以152名中学生为被试,考察成就目标定向、测验焦虑和工作记忆的关系。结果表明四种成就目标定向与测验焦虑和工作记忆间具有不同的关系模式:成绩-接近目标与较低的测验焦虑水平和较高的工作记忆广度相关;掌握-接近目标与担忧、情绪化,与工作记忆广度相关不显著;成绩-回避目标与测验焦虑中的担忧和情绪化正相关,与工作记忆广度负相关;掌握-回避目标与担忧和情绪化存在正相关,与工作记忆广度存在接近显著的相关。测验焦虑是成绩-接近和成绩-回避目标影响工作记忆的中介变量。在测验焦虑中,情绪化对工作记忆的干扰大于担忧的干扰  相似文献

Ninety-four subjects were tested on the Daneman and Carpenter (1980) reading span task, four versions of a related sentence span task in which reaction times and accuracy on sentence processing were measured along with sentence-final word recall, two number generation tasks designed to test working memory, digit span, and two shape-generation tasks designed to measure visual-spatial working memory. Forty-four subjects were retested on a subset of these measures at a 3-month interval. All subjects were tested on standard vocabulary and reading tests. Correlational analyses showed better internal consistency and test-retest reliability of the sentence span tasks than of the Daneman-Carpenter reading span task. Factor analysis showed no factor that could be related to a central verbal working memory; rotated factors suggested groupings of tests into factors that correspond to digitrelated tasks, spatial tasks, sentence processing in sentence span tasks, and recall in sentence span tasks. Correlational analyses and regression analyses showed that the sentence processing component of the sentence span tasks was the best predictor of performance on the reading test, with a small independent contribution of the recall component. The results suggest that sentence span tasks are unreliable unless measurements are made of both their sentence processing and recall components, and that the predictive value of these tasks for reading comprehension abilities lies in the overlap of operations rather than in limitations in verbal working memory that apply to both.  相似文献

本研究采用"视空间和言语交替"任务范式分离言语工作记忆的加工和储存两个成分,分别探讨了英语工作记忆的加工和储存成分对我国中学生英语阅读理解的作用及其途径,以及汉语工作记忆的加工和储存成分对中学生英语阅读理解是否具有跨语言影响。98名初中二年级学生完成了一般认知能力、英语阅读理解、汉语和英语工作记忆任务。结果表明:(1)英语工作记忆的加工和储存成分对英语阅读理解均有显著的独立预测作用;(2)英语工作记忆的储存成分对英语阅读理解的作用部分是由加工成分引起的;(3)汉语工作记忆的加工成分对英语阅读理解没有显著的直接预测作用,但却以英语工作记忆的加工成分为中介间接作用于英语阅读理解;汉语工作记忆的储存成分对英语阅读理解没有显著的预测作用。可见,言语工作记忆是一个多成分系统,加工和储存两个成分是相对分离的,并且它们具有不同的跨语言特性,加工存在跨语言一般性,而储存则具有语言特异性。  相似文献

This study examines age-related differences in reading comprehension analyzing the role of working memory and metacomprehension components in a sample of young (18–30 years), young-old (65–74 years), and old-old (75–85 years) participants. Text comprehension abilities were measured by a standardized test, including two texts: a narrative and an expository text. The elderly's reading comprehension performance, when compared to the norm, emerged to be adequate. More specifically, the young-old showed an equivalent level of comprehension as the young adults for the narrative text. However, a clear age-related decline was found in the case of the expository text. Hierarchical regression analyses showed that working memory capacity, as well as different metacomprehension components but not age, are the key aspects in explaining the different patterns of changes in the comprehension of narrative and expository texts.  相似文献

加工速度、工作记忆与数字推理能力的发展   总被引:2,自引:0,他引:2  
王亚南  刘昌 《心理科学》2006,29(5):1081-1085
本研究得出在数字推理能力的发展过程中加工速度和工作记忆发挥着重要的作用,其中工作记忆对数字推理能力的发展的作用大于加工速度。加工速度可能是年龄与工作记忆的中介,加工速度可能仅对工作记忆的发展起一种直接调节作用,工作记忆对数字推理能力的发展可能起直接调节作用,在数字推理能力的发展过程中工作记忆比加工速度可能发挥着更直接、更一般的作用。  相似文献

分散注意条件下学优生与学困生视空间工作记忆的比较研究   总被引:13,自引:0,他引:13  
张明  隋洁 《应用心理学》2003,9(1):29-34
通过控制干扰刺激量 ,研究分散注意对学优生和学困生视空间WM的影响。实验一的结果表明 :在不同干扰条件下 ,学困生视空间WM均比学优生差 ;干扰任务不仅影响学困生视空间WM的加工能力 ,也影响他们的存储能力。这说明学困生不能有效抑制外界干扰可能是他们视空间WM存在缺陷的主要原因之一。实验二的结果表明 :视空间WM有缺陷是各类学困生普遍存在的问题 ;对于学优生来说 ,不同类型学优生视空间WM不同 ,语文学优比数学学优的学生的视空间WM能力更强 ,主要表现在加工功能上。  相似文献

采用应对自我效能量表、幸福感指数量表和大学生学习倦怠量表对6所高校的713名大学生进行调查,探讨大学生应对自我效能、主观幸福感和学习倦怠三者之间的关系。结果表明:大学生应对自我效能对其主观幸福感具有显著的正向影响作用,大学生主观幸福感对其学习倦怠具有显著的负向影响作用;大学生主观幸福感在应对自我效能和学习倦怠之间起完全中介作用。研究结果进一步揭示了大学生应对自我效能和对其学习倦怠的影响机制。  相似文献

Cohen’s status frustration theory explains that even though everyone is encouraged to achieve a high status in society, lower-class people have very small chances of successfully doing so. Students from a private college and a public community college were given questionnaires about socioeconomic statuses, college majors, career plans, grades, and participation in delinquent activities. Findings support specific components of Cohen’s theory. Minority and lower-class students participated in more deviant behaviors. Results also revealed significant differences in prestige of career goals between students of different social classes. Finally, there was a significant relationship between perceived opportunities and grade point averages.  相似文献

记忆广度包括短时记忆广度和工作记忆广度,为揭示数学学习困难学生认知缺损特点,筛选103名初中生(平均年龄12.57岁),比较数学困难学生(49名)与数学优秀学生(54名)的记忆广度差异,通过词语系列任务、阅读广度任务以及倒背数字任务,分别测查了短时记忆、言语工作记忆以及数字工作记忆。结果发现,数困组与优秀组的学生在词语系列任务中没有显著差异(t=-1.59, p>.05),在阅读广度任务中,具有显著差异(t=-2.38, p<.05),在倒背数字任务中具有极其显著的差异(t=-4.69, p<.01)。阅读广度和倒背数字之间具有显著相关(r=.24, p<.05),词语系列任务与阅读广度(r=.19, p>.05)和倒背数字任务(r=.05, p>.05)之间不存在显著相关。研究表明,在具有干扰情况的任务更能有效预测数学成绩,数学学习困难的认知缺损主要是对抗干扰的能力不足,而非简单的短时记忆广度。  相似文献

The purpose of the present study is to determine if there is a relationship between oral narrative production and the reading comprehension of expository text. The researcher measured both overall and component scores for expository text comprehension and oral narrative production ability of 40 typically-developing fifth grade students. Findings included a moderate correlation between overall expository comprehension and oral narrative production. A significant linear regression indicated that oral narrative production and background knowledge accounted for 18.9% of the variance in expository comprehension. Lastly, significant differences were found in the means of overall oral narrative production, narrative elements, and oral narrative in the single-scene picture condition between the low and high comprehension groups. An implication of this research is that classroom teachers could explore using an oral narrative-based intervention to improve the expository text comprehension of their fifth-grade students.  相似文献

More than a century ago, Galton and Spearman suggested that there was a functional relationship between sensory discrimination ability and intelligence. Studies have since been able to confirm a close relationship between general discrimination ability (GDA) and IQ. The aim of the present study was to assess whether this strong relationship between GDA and IQ could be due to working memory (WM) demands of GDA tasks. A sample of 140 children (seventy 9‐year‐olds and seventy 11‐year‐olds) was studied. Results showed that there was a significant overlap between WM, GDA and fluid intelligence. Furthermore, results also revealed that WM could not explain the relationship between GDA and fluid intelligence as such, but that it acted as a bottleneck of information processing, limiting the influence of GDA on the prediction of fluid intelligence. Specifically, GDA's influence on the prediction of intelligence was only visible when WM capacity was above a certain level. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

The current study reports on an intervention study that investigated the relative contributions of 5‐week English language training (ELT) and 5‐week working memory training (WMT) to improvements in English language knowledge and working memory capacity in university learners of English as a foreign language. The participants were allocated to one of the following three experimental groups and a control group: (i) ELT only; (ii) WMT only; and (iii) both WMT and ELT. The results showed that intervention effects were pronounced in the WMT + ELT group, who improved scores on the reading span test and all tests of verbal and visuo‐spatial short‐term and working memory. The gains on verbal short‐term (Japanese) and working memory (Japanese and English) were maintained 3 months later. None of the interventions, single or combined, were associated with gains in foreign language knowledge, however. The sustained effects of the dual approach and its implications are discussed.

研究选取89名小学三~五年级学生,探讨工作记忆、加工速度、推理能力以及年龄对小学儿童策略适应性的影响。通过路径分析发现:(1)工作记忆和推理能力对策略适应性有直接效应;工作记忆通过推理能力对策略适应性产生间接效应;加工速度通过"加工速度→工作记忆→策略适应性"和"加工速度→工作记忆→推理能力→策略适应性"两条路径对策略适应性起间接作用;在三个因素中,工作记忆对策略适应性的总效应最大,而推理能力对策略适应性的直接效应最大。(2)年龄对加工速度和推理能力有直接效应,但对工作记忆的效应不显著;年龄对策略适应性不产生直接效应,年龄通过"年龄→加工速度→工作记忆→策略适应性"、"年龄→加工速度→工作记忆→推理能力→策略适应性"和"年龄→推理能力→策略适应性"三条路径对策略适应性产生间接影响。  相似文献

基于心理弹性的整合模型和压力与健康关系的终生发展模型,以629名大学生为被试,进行间隔时间为三个月的两次施测,探讨特质正念与大学生焦虑和攻击性的关系及其作用机制。研究发现:(1)特质正念对大学生焦虑和攻击性具有显著的负向预测作用;(2)特质正念通过心理弹性的中介作用预测大学生焦虑和攻击性;(3)留守经历调节了特质正念→心理弹性→焦虑/攻击性的后半段,具体来说,相对于有留守经历的大学生而言,无留守经历大学生心理弹性对焦虑和攻击性的保护作用更为显著。研究结果强调了特质正念和心理弹性是大学生内外化问题的保护因素,而童年期的留守经历是成年后个体心理资源和内外化问题的风险因素,这对大学生内外化问题的干预具有重要的参考价值。  相似文献
