前瞻记忆是对预定事件或行为的记忆,是一种指向来来活动的记忆。最近二十年来,前瞻记忆一直是认知心理学研究的前沿和热点问题之一,其影响因素一直是研究者关注的重要方面。研究者主要从年龄因素、靶线索特征、进行中任务与前瞻记忆任务的匹配性、延时间隔等方面对前瞻记忆影响因素进行了研究。但是由于前瞻记忆加工过程的复杂性以及研究设计等的不同,研究结果并不一致。  相似文献

焦虑是人面临自由选择时存在的心理体验。焦虑症患者或高特质焦虑者在加工信息过程中,对所加工的刺激不是同等程度地分配注意,而是根据刺激的特点进行不同程度的加工,对与威胁相关的刺激产生注意偏向,也就是优先加工威胁性刺激,对威胁性刺激加工效率高。以往对焦虑者注意偏向的研究采用的主要研究范式有:点探测范式和线索-靶子范式。研究的主要被试有:焦虑病人、社交恐惧障碍者和焦虑状态的正常人。选择的实验材料主要是:携带威胁信息的词汇和图片,其中图片主要是带有不同情绪的面孔图片,并以生气的、愤怒的为主。未来的研究应该关注焦虑者注意偏向的形成机制及生理机制。  相似文献

前瞻记忆是指对意向或计划的记忆。研究采用双任务范式,以n-back任务为进行中任务,考察不同认知负荷水平下时间管理倾向对前瞻记忆的影响。结果发现:在中、高认知负荷条件下,积极时间管理倾向者在前瞻记忆中的表现好于消极时间管理倾向者,说明随着认知负荷的增加,需要有效时间管理策略的调控;前瞻记忆在背景任务为1-back、2-back中的加工需要认知资源参与,但在3-back中对认知资源需求不敏感,说明前瞻记忆采用何种加工方式,取决于特定因素,如背景任务的难度等。  相似文献

随着记忆研究向深度和广度发展,前瞻记忆又成为心理学的热点。前瞻记忆是相对于回溯记忆提出的一种特殊的长时记忆,是指记住在将来某个恰当的时间执行先前意向的行为。前瞻记忆的内涵、分类、影响因素,以及前瞻记忆的加工机制和前瞻的老化问题是目前前瞻记忆研究的重点,而前瞻记忆受哪些因素影响以及如何影响是前瞻记忆研究未来的发展方向。  相似文献

目前前瞻记忆已成为记忆研究的一个热点,对于前瞻记忆的影响因素的研究等也深入到众多方面,并且随着PET、ERP、fMRI等技术的运用,人们开始对前瞻记忆的脑机制进行了初步的研究,并确定了某些与前瞻记忆有关的脑区,且对前瞻记忆某些理论模型进行了验征性的研究。这对于前瞻记忆的研究无论是在理论上还是实际的应用上都具有重要的意义。  相似文献

We developed and tested an improved neural network to predict the average concentration of PM10 (particulate matter with diameter smaller than 10 μm) several hours in advance in summer in Beijing. A genetic algorithm optimization procedure for optimizing initial weights and thresholds of the neural network was also evaluated. This research was based upon the PM10 data from seven monitoring sites in Beijing urban region and meteorological observation data, which were recorded every 3 h during summer of 2002. Two neural network models were developed. Model I was built for predicting PM10 concentrations 3 h in advance while Model II for one day in advance. The predictions of both models were found to be consistent with observations. Percent errors in forecasting the numerical value were about 20%. This brings us to the conclusion that short-term fluctuations of PM10 concentrations in Beijing urban region in summer are to a large extent driven by meteorological conditions. Moreover, the predicted results of Model II were compared with the ones provided by the Models-3 Community Multiscale Air Quality (CMAQ) modeling system. The mean relative errors of both models were 0.21 and 0.26, respectively. The performance of the neural network model was similar to numerical models, when applied to short-time prediction of PM10 concentration.  相似文献

Stereotype threat is a situational experience in which an individual feels vulnerable and pressured by the possibility of confirming or being judged by a stereotype. This threatening experience leads to performance decrements, even among highly skilled individuals. This article chronicles empirically tested mechanisms for how stereotype threat negatively impacts performance outcomes. A review of relevant published investigations illustrate that a number of intuitive mediators have been suggested and tested, often with discouraging results. Thus, one objective of this article is to provide researchers with a comprehensive and straightforward account of such tested mechanisms to assist with future works. Indeed, there is much room for research in this area considering that to date, as measured, no individual mediator has completely explained the stereotype threat–poor performance relationship. As such, the second objective of this article is to propose a multiple mediator approach drawing from achievement goal theory. The Stereotyped Task Engagement Process Model is presented. This model hypothesizes that performance goal adoption can offer insights into the potential multiple processes involved in stereotype-threat effects on performance.  相似文献

Native English speaking language teachers who live and work in various parts of the world often express a desire to learn the language of their host country. Without sustained levels of motivation, however, their desires are unlikely to be realized. This article reports the findings of a longitudinal case study of an American English language instructor working at a South Korean university. It examines the factors that impacted her motivation to learn Korean, and explores the ebbs and flows that characterized her motivation over a one-year period. Findings revealed that while the participant did express a desire to learn Korean and formulated learning goals, the action necessary to achieve these goals did not occur. This article draws on the L2 Motivational Self System and the Process Model of L2 Motivation to provide a dual theoretical perspective on the findings.  相似文献

This study was conducted to gather evidence regarding effects of the mode of writing (handwritten vs. word-processed) on compositional quality in a sample of sixth grade students. Questionnaire data and essay scores were gathered to examine the effect of composition mode on essay scores of students of differing computer skill levels. The study was replicated across two writing prompts; essays were assessed on six elements of writing on which a Writing Process Model theoretical framework predicted differences across modes. Statistically significant effects for mode and computer skills were found for some essay elements, although no statistically significant effects were found for others. These results were inconsistent across writing prompts. With the surge in high-stakes testing in American schools and with increasingly more importance being placed on writing skills in many areas, it is critical that test developers ensure that the composition mode of these tests is not putting certain students at a disadvantage. Accordingly, this article concludes with implications for writing instruction and assessment.  相似文献
