认知失调引起的系列次序错误记忆初探

本实验借鉴认知失调领域自由范式的思路,以系列次序为对象,研究了错误记忆在认知失调影响下的产生特点和机制。结果表明：（1）选择操作对被试的次序回忆产生了显著影响：Z（有选择一无选择）=11．036,p〈0．01;（2）在有选择条件下,接受项目的喜好程度增加（X^2（2）=13．000,P〈0．005）,拒绝项目的喜好程度降低（X^2（2）=9．250．P=0．001）;在无选择的条件下,三种位置的频次分布无显著差异,表明认知失调引发了次序错误记忆;（3）预警变量对于次序回忆的相关程度有显著影响（Z（有提示一无提示）=3．535,P〈0．01）,对于接受项目和拒绝项目的位置回忆无显著影响（接受项目：X^2（2）=0．629,P=0．730;拒绝项目：70（2）=0．180,P=0．914）,表明错误记忆是由认知失调引起,并且难以抑制。     

Reducing Affective Polarization: Warm Group Relations or Policy Compromise?

Hostility between rival political partisans, referred to as affective polarization, has increased in the United States over the last several decades generating considerable interest in its reduction. The current study examines two distinct sets of factors that potentially reduce affective polarization, drawn respectively from a group-based and a policy-based model of its origins. Specifically, we contrast the degree to which warm social relations and policy compromise reduce affective polarization. In two experimental studies (N = 937), respondents read a mock news story about an observed interaction between Chuck Schumer, Senate minority leader, and Mitch McConnell, Senate majority leader. The leaders either interact in a warm or hostile manner and independently compromise, or fail to compromise, on immigration matters. In both studies, warm leader relations reduced affective polarization whereas policy compromise did not. We consider the implications of these findings for the study of affective polarization and its reduction.     

心理学研究中的可重复性问题:从危机到契机

可重复性问题是当前科学界面临的共同问题。最近,心理学研究领域的可重复性问题也受到广泛关注,引起了研究者的积极讨论与探索。通过对2008年发表的100项研究结果进行大规模重复实验,研究者发现,心理学研究的成功重复率约为39%,但该研究仍然存在着巨大的争议,不同的研究者对其结果的解读不尽相同。针对可重复性问题,研究者通过数据模拟、元分析以及调查等多种方法来分析和探索其原因,这些研究表明,可重复性问题本质上可能是发表的研究假阳性过高,可疑研究操作是假阳性过高的直接原因,而出版偏见和过度依赖虚无假设检验则是更加深层的原因。面对可重复性问题,研究者从统计方法和研究实践两个方面提出了相应的解决方案,这些方法与实践正在成为心理学研究的新标准。然而,要解决可重复性问题,还需要心理学研究领域的多方参与,尤其是在政策上鼓励公开、透明和开放的研究取向,避免出版偏见。心理学研究者为解决可重复性问题做出的努力,不仅会加强心理学研究的可靠性,也为其他学科解决可重复问题提供了借鉴,推动科学界可重复问题的解决。     

Repetition increases false recollection in older people

Aging is accompanied by an increase in false alarms on recognition tasks, and these false alarms increase with repetition in older people (but not in young people). Traditionally, this increase was thought to be due to a greater use of familiarity in older people, but it was recently pointed out that false alarms also have a clear recollection component in these people. The main objective of our study is to analyze whether the expected increase in the rate of false alarms in older people due to stimulus repetition is produced by an inadequate use of familiarity, recollection, or both processes. To do so, we carried out an associative recognition experiment using pairs of words and pairs of images (faces associated with everyday contexts), in which we analyzed whether the repetition of some of the pairs increases the rate of false alarms in older people (compared to what was found in a sample of young people), and whether this increase is due to familiarity or recollection (using a remember‐know paradigm). Our results show that the increase in false alarms in older people due to repetition is produced by false recollection, calling into question both dual and single‐process models of recognition. Also, older people falsely recollect details of never studied stimuli, a clear case of perceptual illusions. These results are better explained in terms of source‐monitoring errors, mediated by people's retrieval expectations.     

排名列表项目展示方式对于项目评价的极化效应

排名列表是帮助消费者快速识别品牌或产品优劣的手段。研究基于空间隐喻理论, 探究排名列表的不同展示方式(垂直vs水平)对消费者列表项目评价的极化影响及作用机制。通过5个实验发现: 消费者对于垂直排名列表相比水平排名列表中的项目具有更大的评价极化效应, 并且验证了项目感知差异在上述关系中的中介作用, 即垂直排名列表的评价极化效应是由个体较高的排名列表项目感知差异所驱动的。此外, 当属性可评估性较低时, 才会出现不同列表项目的评价极化效应; 相反, 当排名列表项目属性可评估性较高时, 该评价极化效应消失。     

The robustness of false memory for emotional pictures

Emotional material is commonly reported to be more accurately recognised; however, there is substantial evidence of increased false alarm rates (FAR) for emotional material and several reports of stronger influences on response bias than accuracy. This pattern is more frequently reported for words than pictures. Research on the mechanisms underlying bias differences has mostly focused on word lists under short retention intervals. This article presents four series of experiments examining recognition memory for emotional pictures while varying arousal and the control over the content of the pictures at two retention intervals, and one study measuring the relatedness of the series picture sets. Under the shorter retention interval, emotion increased false alarms and reduced accuracy. Under the longer retention interval emotion increased hit rates and FAR, resulting in reduced accuracy and/or bias. At both retention intervals, the pattern of valence effects differed based on the arousal associated with the picture sets. Emotional pictures were found to be more related than neutral pictures in each set; however, the influence of relatedness alone does not provide an adequate explanation for all emotional differences. The results demonstrate substantial emotional differences in picture recognition that vary based on valence, arousal and retention interval.     

The role of attention at retrieval on the false recognition of negative emotional DRM lists

This study examined the role of attention at retrieval on the false recognition of emotional items using the Deese–Roediger–McDermott (DRM) paradigm. Previous research has shown that divided attention at test increases false remember judgements for neutral critical lures. However, no research has yet directly assessed emotional false memories when attention is manipulated at retrieval. To examine this, participants studied negative (low in valence and high in arousal) and neutral DRM lists and completed recognition tests under conditions of full and divided attention. Results revealed that divided attention at retrieval increased false remember judgements for all critical lures compared to retrieval under full attention, but in both retrieval conditions, false memories were greater for negative compared to neutral stimuli. We believe that this is due to reliance on a more easily accessible (meaning of the word) but less diagnostic form of source monitoring, amplified under conditions of divided attention.     

On the advantage of autobiographical memory pliability: implantation of positive self-defining memories reduces trait anxiety

This paper is devoted to the mechanism of the positive construction of autobiographical memory. Positive construction consists of the spontaneous transformation of memories in the direction of the subjective enhancement of self-competence in past activities to anticipate improvement over time. We speculated that trait anxiety may indicate a failure to exhibit this mechanism that results in a deficit of affirmative self-esteem. We hypothesised that the implantation of positive self-defining memories in anxiety-evoking domains would decrease trait anxiety. One hundred twenty adults recollected three negative self-defining memories. Then, half of the participants imagined episodes of desired behaviour that differed from the originally recollected ones either in discussion or in hypnosis. Thirty participants experienced a hypnotic state without any references to memories, and the rest formed the control group. Subjects from the “Memory Implantation in Hypnosis” group became unable to distinguish the originally reported memories from the imagined ones, exhibited decreased trait anxiety scores after a 4-month delay, and reported enhanced self-esteem. In contrast, the participants from the “Hypnosis with no reference to the past” group exhibited decreased scores at a short delay but later returned to their original scores. These findings highlight the power of cured episodic-like autobiographical memory for updating the self.     

Changes in Politics and Religiosity Among Students at a Protestant University

College is a setting and time of profound change in the lives of emerging adults. This change can include shifts in identity related to politics and religion. Given widespread attention to the alignment of religious people with conservative politics and less religious people with liberal politics (i.e., the “God Gap”), we ask: do college students who become politically liberal lose their religion in the process? Using longitudinal panel data, this study examines changes in political identity and religiosity among students at a Protestant university. Findings reveal changes in students’ politics align with changes in public and private religious behaviors, certainty in belief, agreement with core tenets of the Christian faith, faith maturity, and closeness to God. Whereas students who become more politically conservative increase their religiosity, the inverse is true for those whose politics become more liberal in college.
