执行意向影响事件性前瞻记忆的加工机制

本研究旨在探究不同执行意向编码形式对前瞻记忆加工机制的影响是否存在差异。结果显示在低认知负荷下,混合编码效果最好,仅执行意向编码次之,标准编码效果最差,而在高认知负荷下三种编码效果无差异。眼动指标显示在低认知负荷下混合编码的注视点数量最多,总注视时间最长;在混合编码条件下进行中任务和前瞻记忆任务的总注视时间均长于仅执行意向编码和标准编码。结果说明,执行意向编码容易受认知负荷的影响;在低认知负荷下混合编码的被试对任务刺激进行更多的监控和加工,而仅执行意向编码促进前瞻记忆任务的自动化加工。     

自我损耗对基于时间前瞻记忆的影响

采用Stroop任务和前瞻记忆双任务实验范式,比较不同自我损耗条件对被试基于时间前瞻记忆（TBPM）的影响,及其对TBPM的加工阶段和成分的作用。然后通过添加外部时钟监控条件,探讨外部时钟是否可以减少自我损耗对TBPM的消极影响,以及自我损耗对时钟监控情况的作用。结果表明：（1）在内部控制条件下,自我损耗会严重影响TBPM的表现,高损耗组的TBPM成绩显著低于低损耗组,另外,自我损耗主要干扰前瞻记忆的前瞻成分和TBPM的第三个加工阶段。（2）在外部控制条件下,自我损耗没有降低TBPM的表现,说明外部时钟可以降低自我损耗对TBPM的消极影响。（3）自我损耗使个体呈现出不同的时钟监控模式,且邻近目标时间内的时钟监控次数与TBPM成绩呈显著正相关。     

基于事件的前瞻性记忆的年老化

采用类别判断任务作为正在进行任务,采用Einstein的研究范式探讨了前瞻性记忆是否随年龄的老化而出现年老化现象。结果表明,当前瞻性记忆任务和当前进行的任务要求的认知过程一致时,前瞻性记忆成绩不会随增龄下降;当前瞻性记忆任务和当前进行的任务要求的认知过程不一致时,前瞻性记忆出现了年老化现象;前瞻性记忆成绩和自由回忆成绩无显著相关     

Collaboration inflation: Egocentric source monitoring errors following collaborative remembering

Following collaborative remembering, people may adopt their partner's contributions as their own memory. In two studies, we asked people to study partially overlapping lists of words. During collaborative remembering, dyads either worked to include all words no matter who studied them or limited recall to only words studied by both dyad members. This differential focus on source information during collaborative recall impacted performance on a later source memory test. Nonetheless we found frequent source monitoring errors that displayed an egocentric bias. People were more likely to claim their partner's contributions as their own memories than attribute their memories to their partners. In collaborative remembering, people work to construct an agreed upon version of the past that quickly becomes each individual's memory.     

Remembering stories together: Social contagion and the moderating influence of disagreements in conversations

Although remembering often occurs with conversations, the effects of its pragmatics on memory are rarely examined. We studied the effect of two pragmatic factors: (1) the presence of disagreeing and (2) the level of participation in the disagreement. In the present study, each participant read a slightly different version of four stories, thereby allowing for the possibility of social contagion through the conversation. They then jointly recounted the stories. We coded for the presence or absence of disagreements, and whether a participant contributed to the disagreement. Three factors mediated social contagion: (a) the presence or absence of an overt disagreement; (b) whether or not a member of a conversational remembering participated actively in a disagreement; and (c) how well participants remembered the original material. Both the pragmatics of conversations and quality of memory are important factors moderating social contagion.     

Virtual Week: Validity and psychometric properties of a Polish adaptation

IntroductionProspective memory (PM) refers to memory for future intentions and it is essential for safe and independent living. This paper focuses on Virtual Week (VW), a measure that was developed to closely represent everyday PM tasks in an English language setting in North America and Australia.ObjectivesThe main objective of the present study is to offer the results of a Polish adaptation of VW and present the validity and psychometric properties of the adapted version.MethodThe Spearman-Brown split-half reliability coefficients and Cronbach's alphas were estimated in 77 young adults and 83 healthy older adults. To confirm the validity of the Polish VW, we analyzed whether it is sensitive to the pattern of PM deficits in the healthy elderly that is consistent with mechanisms underlying PM performance as well as theories of normal aging.ResultsThe Polish VW was found to have strong psychometric properties and be sensitive to theory- and data-based effects on PM.ConclusionThe findings strongly encourage the use of VW for experimental purposes in healthy older adults. They provide further evidence that VW has a universal appeal and may be used in non-English speaking European samples.     

God’s Faithfulness and Dementia: Christian Theology in Context

Christian theology concerns the practical, contextual realities of life in the church and the world. What does this mean for a person with dementia? While much dementia care focuses on deficits, this article promotes a different starting point: God’s faithfulness rather than our forgetfulness. Using case studies from residential aged care, opportunities for meaningful pastoral care are explored, inviting us to see in the person with dementia a deep connection with ourselves. Drawn from a theological understanding of God as three persons—Father, Son and Holy Spirit—“person-centered care” invites us into relationships of mutuality and reciprocity not dependent on words. Pastoral care of families is manifest through personal relationships where all aspects of dementia, including death and dying, can be discussed openly. Grounded in God’s faithfulness, the first and final word is love. Hope lies in the belief that we have already been found. We are blessed by the grace of God, called into community where the insightful and the forgetful flourish together.     

成员关系对协作提取成绩的影响

当人们与搭档组成社会群体一起协作讨论某些已经发生的事件或经验时, 该社会群体中的成员关系对协作提取成绩的影响仍不明确。本研究通过两项实验, 分别使用语词词单和情景故事作为实验材料, 考察成员关系(包括关系类型和关系时长)对协作提取成绩的影响。研究结果表明, 当记忆的材料为语词词单时, 青年陌生组出现了协作抑制; 而当记忆的材料为情景故事时, 青年夫妻和老年夫妻组均出现了协作促进。此外, 老年夫妻在协作提取情景故事的过程中使用的有效交流策略更多, 且这些有效交流策略的使用与更高的协作提取成绩有关。该结果支持了具有长时亲密关系的老年夫妻之间的“交互记忆系统”对协作促进的关键作用, 为理解成员关系对协作提取成绩的影响提供了全面的证据。     

Imaginary Companions in Childhood: What Can Prospective Longitudinal Research Tell Us About Their Fate by Adolescence?

Do adolescents remember imaginary companions (ICs) from early childhood? Researchers interviewed 46 adolescent participants in a prospective longitudinal study about their ICs from early childhood (age 5½). The existence of one or more ICs was documented in early childhood for 48% of children (G. Trionfi & E. Reese, 2009). At age 16, most adolescents had forgotten their early childhood ICs: Only 5 of the 23 participants who had early childhood ICs recalled those ICs later. Eight participants who had forgotten their early childhood ICs recalled a later IC, and four participants who did not have an IC at age 5 ½ reported one by age 16. Ten of the 23 participants who had early childhood ICs claimed never to have had an IC. Girls were more likely to recall their early childhood ICs. Retrospective reports of ICs in adolescence or later life may be unreliable for investigating differences between those with and without imaginary companions. Those with ICs may not be a homogenous group, with some creating ICs throughout childhood and some desisting from this behavior in early childhood. Findings indicate that both the remembering and forgetting of ICs has potential to illuminate cognitive and creative processes surrounding both memory and imagination.     

An Experimental Investigation of Election Promises

We analyze the effect of election promises on electoral behavior in a laboratory experiment. In the experiment, politicians can make nonbinding election promises about how to split an endowment between themselves and the group. We find that promises affect both voting and voter beliefs about how much the politician will contribute to the public fund. The relationship is inverted U‐shaped with decreasing credibility of higher promises. Contributions of politicians are correlated with their promises in a similar pattern. The election promises are generally credible unless particularly high. Politicians keep promises more often if a reelection is possible and if the politician came into power by vote rather than by random draw. Voters reward high contributions in the previous period and punish promise breaking even after controlling for the contribution in the previous period or voters' beliefs about future contributions. By controlling for voters' beliefs, we distinguish retrospective from prospective voting. Our results suggest that voters both use promises for prospective voting and retrospectively punish broken promises.
