元分析的特点、方法及其应用的现状分析   总被引:11,自引:0,他引:11  
元分析是心理、教育及其他科学领域内新近出现的一种重要研究方法,它主要是借助统计方法,对针对同一问题的大量研究结果进行综合分析与评价,从而概括出其研究结果所反映的共同效应,即普遍性的结论。但这种方法在目前国内心理与教育研究中仍不多见。本文首先将通过与其他整合研究结果的分析方法的比较,归纳出元分析的主要特点及其局限性,其次本文着重介绍目前应用较为广泛的三种重要的元分析方法,并对三种方法作出比较分析;最后本文还将对元分析技术在国内心理学研究中的应用现状作分析与评价。  相似文献

Three studies tested the valence-framing effect: that merely conceptualizing one's preferences as opposing something will make that preference more resistant to persuasion than will thinking about the same preference in terms of supporting something . In Study 1, participants who were led to conceptualize their political preferences as being against a candidate were more resistant to a counterattitudinal message than were participants who were led to conceptualize the same preference as being in favor of the other candidate. Study 2 showed that this effect was not due to a priming process, while Study 3 provided evidence for the effect's generalizability.  相似文献

People’s greater willingness to help identified victims, relative to non-identified ones, was examined by eliciting real contributions to targets varying in singularity (a single individual vs. a group of several individuals), and the availability of individually identifying information (the main difference being the inclusion of a picture in the “identified” versions). Results of the first and second experiments support the proposal that for identified victims, contributions for a single victim exceed contributions for a group when these are judged separately, but preference reverses when one has to choose between contributing to the single individual and contributing to the group. In a third experiment, ratings of emotional response were elicited in addition to willingness to contribute judgments. Results suggest that the greater contribution to a single victim relative to the group stems from intensified emotions evoked by a single identified victim rather than from emotions evoked by identified victims in general.  相似文献

阐释学语境下的医患沟通——探寻理解之路   总被引:5,自引:2,他引:3  
在信息不对称、医疗结果不确定的情况下,很多医疗纠纷是由于缺乏充分的沟通导致不信任和误解造成的。加强医患沟通是增进理解、减少误解、构建和谐医患关系的重要途径。结合阐释学提出的理解之“主体间性”、“视阈融合”、“效果历史”的观点,探寻医患沟通的理解之路并指出医患沟通的限度。  相似文献

工作记忆训练及对数学能力的迁移作用   总被引:7,自引:3,他引:4

工作记忆缺陷会影响个体数学能力发展。通过记忆策略、广度、刷新、转换等功能的工作记忆训练,可以改善个体认知功能。然而,工作记忆训练对个体的阅读、数学、流体智力等方面的远迁移效果并不一致。研究表明,工作记忆训练可以改善数感、视觉空间能力、推理能力等数学一般技能;也会通过改善语音工作记忆以及空间能力促进数学计算能力,或者通过改善中央执行系统,提升数学问题表征、模式识别、解题迁移、策略选择等复杂的过程,从而促进数学问题解决能力。因此,区分不同数学任务的认知过程,可以获得工作记忆训练对数学能力迁移效果的进一步证据。今后,神经影像学的证据或许也是未来工作记忆训练对数学能力提高的又一佐证。  相似文献

阶层流动是指人们在社会分层体系中相对位置的变化。人们普遍预期,向上流动促进个体发展和社会进步。然而近期研究也表明,向上流动还可能损害个体健康和主观幸福感,使人们低估和容忍社会不平等,并反对再分配。地位认同、贫富归因倾向以及系统公正信念能够解释向上流动的双刃剑效应。未来研究需要进一步澄清向上流动感知的具体表现,深入考察向上流动影响的心理机制,探索促进阶层流动积极效应发挥的干预方法。  相似文献

The effects of contextual shifts on the partial reinforcement extinction effect (PREE) were studied in autoshaping with rats. Experiment 1 established that the two contexts used subsequently were easily discriminable and equally salient. In Experiment 2, independent groups of rats received acquisition training under partial reinforcement (PRF) or continuous reinforcement (CRF). Significant PREEs were observed whether extinction occurred in the same or in a different context. In Experiment 3, after PRF or CRF acquisition training, each group received extinction of the same conditioned stimulus in both the same and different contexts. PREEs were observed under both conditions, although extinction was accelerated after a contextual shift. These results were discussed in relation to the role of mediational states in the PREE.  相似文献

Five experiments were conducted to explore trial order and retention interval effects upon causal predictive judgments. Experiment 1 found that participants show a strong effect of trial order when a stimulus was sequentially paired with two different outcomes compared to a condition where both outcomes were presented intermixed. Experiment 2 found that a 48-h retention interval eliminates the trial order effect, so that participants gave a global judgment about the relationship between the stimulus and the two outcomes equivalent to the one given by participants that received the two phases intermixed. This result was replicated in Experiment 3 in a situation in which the probability of the outcome in the presence of the cue was changed from .5 for both outcomes (Experiments 1, 2, 4, and 5) to .75 and .25 for outcomes 1 and 2, respectively. Experiment 4 found that retention intervals ranging from 45 min to 48 h eliminated the trial order effect similarly. Experiment 5 found that a 10-min retention interval replicated the effect of time upon sequential training found in precedent experiments, regardless of whether participants remained within the laboratory during the retention interval or spent it outside. The combined results of this experimental series suggest that retention intervals reduce retroactive interference in causal learning by allowing participants to use all the information presented across phases, rather than differentially increasing or decreasing retrieval of information about each of them.  相似文献

Abstract: The present study examined recognition for sequences of scenes depicting emotional compared with neutral events. In two experiments, participants were presented with a thematic series of 18 slides of scenes in which the content of two critical scenes in the middle of the series were either emotional (dead men's bodies) or neutral (an opera). A two‐item, forced‐choice recognition paradigm was used to test participants’ immediate memory performance of all 18 slides of scenes. In Experiment 1, anterograde and retrograde amnesic effects were observed for the emotional, but not the neutral scenes when a test sequence of scenes was used that did not match the original presentation order. In contrast, in Experiment 2 the test sequence matched the order seen during the original presentation, and both the anterograde and retrograde amnesic effects were not found. These results indicate that the reinstatement of the original event context is an important factor for the recognition of negative emotional memories.  相似文献
