In testing hypotheses, researchers frequently have used multiple regression analysis to control for nuisance variables (i.e., potential confounding variables that are correlated with hypothesized causal variables). In this paper, we highlight limitations of this control strategy, and we discuss fundamental issues that should be considered in deciding whether to use it. Ultimately, we suggest the use of multiple regression analysis sometimes may not improve causal understanding and may actually limit the generalizability of results. Instead of the common practice of controlling for nuisance variables, we suggest that looking at shared variance frequently is a more appropriate test of a theoretical hypothesis. 相似文献

This article highlights and summarizes efforts that have been made primarily during the past 20 years to bring the significance of relational diagnosis to the attention of the entire mental health community, and either (1) to have dysfunctional relational interactive patterns classified and codified and accepted for inclusion in the Diagnostic and Statistical Manual of Mental Disorders, or (2) if this is not feasible, to have a nosology of relational diagnoses, which have been clearly defined with accompanying risks specified for mental illnesses that might develop, and criteria sets delineated and adequately field tested to warrant and lead to publication of a separate but equal Diagnostic Manual of Relational Disorders and Dysfunctional
Interactional Patterns. 相似文献

The present research examined the social context of information acquisition. The main purpose was to examine how decision‐makers' information acquisition processes changed when they were provided access to expert advice. Results indicated that all decision‐makers opted to acquire advice; however, they typically did so only after completing over 75% of their own information search. Decision‐makers agreed more with the advice as task complexity increased, but, in general, searched information in two stages—i.e., a pre‐advice “hypothesis generation” stage and a post‐advice “hypothesis testing” stage. To behave in an adaptive manner, decision‐makers could have used expert advice either to increase their decision accuracy or to reduce their effort expenditure (or both); they chose the former. Implications and further extensions are discussed. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

ABSTRACT— Researchers studying human memory have increasingly focused on memory accuracy in aging populations. In this article we briefly review the literature on memory accuracy in healthy older adults. The prevailing evidence indicates that, compared to younger adults, older adults exhibit both diminished memory accuracy and greater susceptibility to misinformation. In addition, older adults demonstrate high levels of confidence in their false memories. We suggest an explanatory framework for the high level of false memories observed in older adults, a framework based on the theory that consciously controlled uses of memory decline with age, making older adults more susceptible to false memories that rely on automatic processes. We also point to future research that may remedy such deficits in accuracy. 相似文献

The relationship between affect and metacognitive processes has been largely overlooked in both the affect and the metacognition literatures. While at the core of many affect-cognition theories is the notion that positive affective states lead people to be more confident, few studies systematically investigated how positive affect influences confidence and strategic behaviour. In two experiments, when participants were free to control answer interval to general knowledge questions (e.g. question: “in what year”, answer: “it was between 1970 and 1985”), participants induced with positive affect outperformed participants in a neutral affect condition. However, in Experiment 1 positive affect participants showed larger overconfidence than neutral affect participants. In Experiment 2, enhanced salience of social cues eliminated this overconfidence disadvantage of positive affect relative to neutral affect participants, without compromising their enhanced performance. Notably, in both experiments, positive affect led to compromised social norms regarding the answers’ informativeness. Implications for both affect and metacognition are discussed. 相似文献

一般来说,对于计算机人格适应性测验(CAPT),由于对被试每种人格特质的施测项目数比较少,初始值估计方法的好坏直接影响着被试人格特质水平估计的准确性。该研究提出利用被试特质水平与其人格特质自我评定信息的回归模型来获取被试人格特质水平的初始值。模拟数据的研究结果表明:新方法获得的初始值确实能够更准确的估计被试的特质水平。 相似文献

阅读中的元理解监测与元理解调控 总被引:1,自引:0,他引:1
采用“阅读-关键词处理-元理解监测-测验1-选择文章重读-测验2”的流程, 探讨元理解监测对元理解调控与阅读理解成绩的影响。结果显示, 延迟写关键词相对于即时写和不写关键词更利于监测精 确性的提高; 延迟关键词组借助精确的监测能做出有效的元理解调控, 选出测验1中得分低的文章重读, 并在测验2中有较好表现, 而其他两组只能选出其认为难的、而非得分低的文章重读, 在测验2中表现不 佳。元理解监测的精确性影响元理解调控的有效性, 进而影响阅读理解成绩。 相似文献

This study investigates abstracted processes and introduces a new prototype abstraction model adapted to estimation tasks. This prototype abstraction model assumes that the processing of whole exemplar patterns supports the detection of the underlying statistics necessary for the abstraction of two extreme prototypes on the continuous criterion dimension of the task. The prototypes are stored in memory as valid reference points for future similarity-based judgments. This prototype model was compared with the cue abstraction model, which assumes that people abstract cue weights in learning and add the cue information from exemplars to infer their criterion values varying on the continuous dimension. This study hypothesises that the training mode and the number of exemplars in training interact and affect subsequent model performance at test. The results from an experiment confirmed this hypothesis and showed that observational training supports an efficient prototype abstraction and feedback training supports an efficient cue abstraction. 相似文献

作为社会学习的个体,幼儿从3岁起就能根据信息提供者先前准确性的差异对其可信程度进行评估。通过对以往研究效应量的整理分析发现,随年龄增长,幼儿对高先前准确性信息提供者的信任程度表现出增长趋势(3岁幼儿选择的效应量中值为d询问=0.60,d赞同=0.61;4岁幼儿的效应量中值为d询问=0.80,d赞同=0.96)。在运用先前准确性进行评估时,幼儿主要关注信息提供者是否犯错,灵活使用"整体印象"和"特质推测"两种认知策略对其未来行为进行推测。幼儿能够根据自身对材料的感知对信息提供者的可信程度进行动态调整,其心理理论发展水平和执行功能限制了他们的选择信任,而信息提供者同时具有的社会性因素对幼儿的选择也具有干扰作用(幼儿信任准确的信息提供者的效应量中值为d询问=-0.03,d赞同=-0.17)。未来研究可以改进实验范式,进一步探查先前准确性对幼儿选择性信任的影响,拓展信息提供者的呈现方式和其它多重特征,关注不同类别的信息提供者。 相似文献
