优、差生组织策略水平的比较研究

本文比较了初一年级优、差生在词表记忆中的组织策略水平的差异,结果表明：１、初一年级优、差生都还没能自发地运用组织策略,优生只在非典型项目的记忆中群集水平明显优于差生,优、差生的群集水平和记忆成绩之间不存在一一对应的关系。２、在典型或非典型项目的记忆中,记忆成绩和知识背景都有着非常显著的正相关。     

小学优生与差生完成系列回忆任务错误类型发展的实验研究

主要探讨了小学优生与差生在完成系列回忆记忆任务时出现错误的发展情况。实验以小学一、三、五年级的学生作为被试,每年级优生与差生各10名。以普通(不形似,不近音)、形似和近音三种类型汉字为实验材料,要求被试按材料呈现的顺序进行回忆。结果发现：在完成系列回忆任务时,小学生表现出四种错误类型,错误率从高到低依次是：移动错误、遗漏错误、侵入错误、重复错误。每一类型的错误率都是优生显著少于差生。研究还发现四种错误受材料特点的影响,即各年级小学生错误率从高到低近音字、形似字、普通字。     

初中优生和差生学习适应性的比较研究

研究采用《学习适应性测验(AAT)》,对初中优生和差生的学习适应性水平进行测查比较,结果表明：初中优生和差生的学习适应性总体上存在着极其显著差异,不同年级的优生之间、不同年级的差生之间的学习适应性也各自存在显著差异,而不同性别的优生和差生的学习适应性不存在显著差异。同时,研究者探讨了差异产生的原因及其影响。     

词频和年级对FOK判断的影响

本实验以识记材料的词频高低和被试年级为自变量对被试元记忆监测的FOK(feeling of knowing)判断进行研究。实验采用Hart提出的RJR(回忆—FOK判断—标准测验 )的经典范式。结果表明 :被试的年级影响FOK判断等级和准确性 ,大学生的FOK判断等级和准确性均高于高一年级学生 ;识记材料词频影响FOK判断等级的高低 ,不影响FOK判断准确性 ,被试对高频词对的FOK判断等级高于对低频词对的FOK判断等级 ,但FOK判断准确性无明显差异。     

解题反思对数学学业优差生解题过程的影响

考察解题反思对数学学业优生和差生解题结果及所用策略的不同影响。选取初一至初三年级的数学学业优生和差生为被试,以一套连加数问题为实验材料,进行一对一的测试,前后进行两次测试。对反思组优差生(优生12人,差生10人)和无反思组优差生(优生14人,差生14人)解题过程的比较,发现:1)解题后立即进行反思能够提高差生的解题正确率,但是延长解题时间;2)先前的解题反思对优生和差生后续解题时的正确率和解题时间均不产生明显影响;3)解题后立即进行反思能够促进优生和差生使用高效策略,放弃低效策略;4)先前的解题反思在后续解题中仍然促进学生使用高效策略,对优生的促进作用比对差生更明显。

本研究以眼动仪为工具,采用移动窗口范式来考察小学五年级语文学优生和学困生的阅读知觉广度。实验结果发现,小学五年级语文学优生的阅读知觉广度范围为注视字左侧一个汉字到注视字右侧三个汉字,小学五年级语文学困生的阅读知觉广度范围为注视字左侧一个汉字到注视字右侧两个汉字。小学五年级语文学优生的阅读知觉广度比学困生更大。     

小学2-4年级儿童数学应用题表征策略对其解决不规则问题影响的研究

本研究运用实验法和临床访谈法对某普通小学的123名2-4年级学生进行了不规则数学应用题测验,以考察数学学优生和学差生在解决这些应用题时表征策略的差异。结果表明：（1）从2-4年级儿童解答条件多余和条件不足应用题上看,学优生的成绩要好于学差生,口头报告分析显示学优生较多地使用问题模型策略对问题进行表征,而学差生较多使用直接转换策略对问题进行表征;（2）在三年级时,条件多余和条件不足应用题的解题正确率有所提高,但到四年级时,正确率却有所下降;（3）在解决条件多余和条件不足应用题中,性别差异不显著。     

学困生关于材料特征的元认知知识与应用的实验研究

小学学习不良学生和正常学生的认知特点

本研究运用杭州大学心理系所编的《儿童认知能力诊断量表》,测试了小学一、三、五年级中的学习不良生(简称差生)和正常生的观察力、记忆力和思维推理能力,并对差生和正常生的认知能力的发展特点作了比较,以资鉴别差生及了解造成差生学习成绩落后的原因提供某些实验依据。在本研究的取样范围内,我们得到以下结论:1.小学儿童中正常生和差生的认知能力都是随着年级的升高而不断发展的,但各种认知能力的发展是不平衡的。2.在量表成绩上,相同年级的差生与正常生相比,在某些认知能力上显著地落后,且在各种认知能力的发展进程上也各有其特点。3.在认知能力质的特点上,差生的发展水平明显落后于同年级的正常生,但就总的发展趋势而言,差生与正常生并无本质区别。     

An analysis of the determinants of the feeling of knowing

Research has demonstrated that feeling-of-knowing (FOK) judgments are affected by the amount of accessible information related to an inaccessible target. Further, studies have demonstrated that, in some situations, FOK judgment magnitude is not only related to the amount (quantity) of accessed features, but also the correctness of those features (Thomas, Bulevich, & Dubois, 2011). The present study examined the conditions under which the correctness of features would influence FOK judgment magnitude. We hypothesized that accuracy of retrieved features would influence FOK judgments, but only in situations where semantically meaningful information was accessible. In three experiments, we manipulated accessibility of semantic information. In all experiments, the quantity, or amount of retrieved partial information had a greater impact on FOK judgments than the accuracy of that information. However, in situations where semantic information was accessible, accuracy of retrieved semantic features also influenced FOK judgment magnitude, and later recognition.     

FOK与情节记忆、语义记忆和内隐记忆关系的研究

实验采用R/K判断和PDP测量技术,研究了FOK判断与情节记忆、语义记忆和内隐记忆关系及其监测强度.实验结果表明FOK判断的准确性程度为R判断＞K判断,即对情节记忆监测的准确性要大于对语义记忆监测的准确性.FOK对于自动加工的预测准确性差异不显著,说明FOK监测对内隐记忆的作用是微弱的,由此推测无记忆是意识最高层面的活动.对记忆监测水平强度是由意识--无意识逐渐减弱的.FOK判断对意识性水平较高的记忆活动监测的准确性较强.     

内隐的可接近信息对FOK判断等级和准确性的影响

该研究使用RJR研究范式,探讨内隐的可接近信息对FOK判断等级和判断准确性的影响。结果发现：FOK判断等级受内隐的可接近信息量的影响,二者呈非单调递增、递减的关系;FOK判断等级随内隐的可接近信息强度的增强而增高;FOK判断准确性随内隐的可接近信息量的增多而降低,并随内隐的可接近信息强度的增强而增高。     

知道感（FOK）和不知道感（FOnK）的双向实验分离

为了实现FOK（feeling-of-knowing）和FonK（feeling-of-not-knowing）的双向分离,实验一采用高频词或者低频词为线索项目,检验FOK和FOnK的预测准确性。结果发现,在低频线索条件下FOK的预测准确性表现出高于FOnK的预测准确性的趋势,而在高频线索条件下则正好相反,但上述两组差异并未在统计学上达到显著的程度。实验二采用词－非词对和相关词对两种实验条件,在证明相关词对条件可以促进FOK并降低FOnK的同时,观察到词－非词条件可以促进FOnK并降低FOK,从而在较为严格的意义上证明了FOK和FOnK是两个不同的维度的量。上述结果为知道感的“双过程假设”提供了进一步的实验证据     

知道感与不知道感：两种不同的认知加工过程——一项来自行为实验的证据

脑成像研究表明,准确的知晓感（FOK）可以分为知道感和不知道感,两者可能依赖不同的大脑机制实现。该研究通过两个实验,检验了线索和靶子的频率对FOK判断准确性的影响,并在行为水平上考察了“知道感和不知道感可能通过不同的认知过程来实现”的假设。实验一表明：靶子字的频率对FOK判断的准确性有影响,即靶子为低频字时,FOK判断的准确性降低;同时,线索和靶子的字频对知道感和不知道感判断的等级没有影响。实验二显示：线索熟悉性只影响准确的不知道感判断等级,而靶项目强度只影响准确的知道感判断等级,即产生了非交叉的双重分离。综上,我们发现了靶子的字频对FOK判断准确性的影响,并从行为实验的角度证实,知道感和不知道感依赖不同的认知加工过程。     

FOK产生机制的再验证

通过用有意义联系和无意义联系的两种中文词对作为识记材料,在以前实验研究基础上,进一步验证关于FOK(Feelingof Knowing)产生机制的两种理论假说,即靶项日记忆强度假说(或靶项目提取可能性假说)与线索熟悉性假说。实验结果表明,靶项目记忆强度和线索熟悉性程度都能决定FOK判断等级的高低,说明两种假说并非绝对对立,非此既彼。但此二因素都需达到一定程度,才能显著影响FOK判断等级的高低。     

Testing the Mediating Effect of the Quality of College Life in the Student Satisfaction and Student Loyalty Relationship

This study tests the mediating effect of the quality of college life (QCL) in the student satisfaction and student loyalty relationship. QCL refers to the degree of need satisfaction and the experiences that create a positive affect throughout college life. The QCL of students is conceptualized as a higher order construct that is composed of need satisfaction and affect balance. It has been hypothesized that student satisfaction with university services has a significant impact on QCL, which in turn positively influences student loyalty. The results from the survey of 228 college students largely supported the model. Both the managerial and policy implications of this study are discussed.

Recalled aspects of original encoding strategies influence episodic feelings of knowing

We tested the hypothesis that the feeling of knowing (FOK) after a failed recall attempt is influenced by recalling aspects of the original encoding strategy. Individuals were instructed to use interactive imagery to encode unrelated word pairs. We manipulated item concreteness (abstract vs. concrete) and item repetitions at study (one vs. three). Participants orally described the mediator produced immediately after studying each item, if any. After a delay, they were given cued recall, made FOK ratings, and attempted to recall their original mediator. Concreteness and item repetition enhanced strategy recall, which had a large effect on FOKs. Controlling on strategy recall reduced the predictive validity of FOKs for recognition memory, indicating that access to the original aspects of encoding influenced FOK accuracy. Confidence judgments (CJs) for correctly recognized items covaried with FOKs, but FOKs did not fully track the strategy recall associations with CJs, suggesting emergent effects of strategy cues that were elicited by recognition tests but not accessed at the time of the FOK judgment. In summary, cue-generated access to aspects of the original encoding strategy strongly influenced episodic FOKs, although other influences were also implicated.     

Context affects feeling-of-knowing accuracy in younger and older adults

In feeling of knowing (FOK) studies, participants predict subsequent recognition memory performance on items that were initially encoded but that cannot presently be recalled. Research suggests that FOK judgment magnitude may be influenced by the total amount, or quantity, of contextual information retrieved related to the unrecalled target (e.g., Koriat, 1993). The present study examined the contribution of quality of that information to episodic FOK judgments. In addition, we tested whether the episodic FOK deficit demonstrated by older adults could be reduced by encouraging retrieval of contextual information relevant to the target. Three experiments demonstrated that quality of the retrieved partial information influenced FOK judgments in both older and younger adults; however, the manifestation of that influence was age dependent. The results also indicated that older adults required explicit retrieval of contextual information before making FOK judgments in order to make accurate FOK predictions. The results suggest that FOK accuracy may be partially determined by search processes triggered when participants are queried for contextual information.
