本文通过一个关于测验作弊的实验研究,揭示了道德唤起与道德行为之间存在的一定关系,即不同的道德唤起水平会对道德行为产生一定的影响。通过实验后的个别访谈,我们分析了道德认知、道德情感与道德唤起之间的关系。最后,我们提出了本实验研究的不足之处和可能存在的后续研究。     

Counterfactual closeness and predicted affect

Empirical research on counterfactual thinking has found a closeness effect: people report higher negative affect if an actual outcome is close to a better counterfactual outcome. However, it remains unclear what actually is a “close” miss. In three experiments that manipulate close counterfactuals, closeness effects were found only when closeness was unambiguously defined either with respect to a contrasted alternative, or with respect to a categorical boundary. In a real task people failed to report greater negative affect when encountering a close numerical miss, while they predicted greater negative affect hypothetically. These results show that counterfactual closeness effects on affect depend on closeness being accessible and unambiguously defined.     

Counterfactual thinking and false belief: the role of executive function

The purpose of the current study was to examine further the relationship between counterfactual thinking and false belief (FB) as examined by Guajardo and Turley-Ames (Cognitive Development, 19 (2004) 53-80). More specifically, the current research examined the importance of working memory and inhibitory control in understanding the relationship between counterfactual thinking and FB. Participants were 3-, 4-, and 5-year-olds (N = 76). Counterfactual thinking statements generated accounted for significant variance in FB performance beyond age and language. Working memory and inhibitory control each partially mediated the relationship between counterfactual thinking and FB performance. The maturation of executive functioning skills is important in children’s developing understanding of counterfactual reasoning and FB.     

Memories of past episodes shape current intentions and decisions

This research tested the hypothesis that people's decisions and future plans are influenced by recently activated autobiographical memories. University students rated the overall quality of their college experiences. They were also asked to describe a specific memory of being either satisfied or dissatisfied with the university. Control participants did not describe a memory. After statistically controlling for pre-existing attitudes towards the university, students who recounted a positive memory expressed the strongest intentions to donate money to the university, attend a class reunion, and recommend the university to others, and they were more likely than controls to specify that an actual donation be made to the university rather than to another charity. Emotional intensity of positive memories predicted future plans and donation decisions. Students who recounted a negative memory also tended to favour the university in their actual donation decisions compared to controls. Prompting the recall of emotional memories may be an effective way to influence intentions and decisions.     

Moral sentiment predicts desire for Scottish independence

Scottish independence has been a topic of considerable political debate for some time, with the 2014 referendum concerning whether Scotland should remain a part of the United Kingdom testament to this fact. Numerous economic and political factors have been noted as determinants of the referendum vote. However, the role of psychological factors as a predictor of the desire for independence has not been well explored despite much work demonstrating the importance of specific traits and values on a range of socio-political attitudes. In the current study, using a sample of Scottish adults (n = 271), we sought to examine how two core constructs capturing moral sentiment – binding (reflecting concern for group cohesion and norms) and individualizing (reflecting concern over individual rights) – predicted the desire for independence during the build-up to the referendum. Results indicated that lower binding and higher individualizing predicted a desire for independence, with evidence for mediation via Scottish identification. These findings are consistent with the notion that the Scottish independence movement can be viewed as a broadly left-wing phenomenon. More generally, these results provide novel evidence in a charged political debate that moral sentiments concerning how individual and group life should be structured play a significant role in explaining individual differences in political sentiment.     

Associations between components of rumination and autobiographical memory specificity as measured by a Minimal Instructions Autobiographical Memory Test

Clinical studies have shown that rumination functions as a mediator between overgeneral memory—the tendency to retrieve autobiographical memories in a non-specific format—and depression. Recently, rumination has been dismantled into two distinct subcomponents: reflection, which is more adaptive, and brooding, which is more maladaptive. In the present study we examined the differential relationships of these two rumination subcomponents with autobiographical memory specificity and their mediational role for the relationship between reduced memory specificity and depression in a non-clinical sample. In addition, we investigated the usefulness of a “minimal instructions” version of the Autobiographical Memory Test (AMT) to measure memory specificity in non-clinical populations. Results indicated that the use of minimal instructions can increase the AMT's sensitivity to detect reduced autobiographical memory specificity in non-clinical individuals. Further it was found that brooding, and not reflection, is significantly associated with reduced autobiographical memory specificity and functions as a mediator between reduced memory specificity and depression.     

Development and psychometric properties of a new measure for memory phenomenology: The Autobiographical Memory Characteristics Questionnaire

The purpose of this study is to develop a valid and reliable measure for the phenomenology of autobiographical memories. The psychometric properties of the Autobiographical Memory Characteristics Questionnaire (AMCQ) were tested in three studies: the factor structure of the AMCQ was examined for childhood memories in Study 1 (N = 305); for autobiographical memories related to romantic relationships in Study 2 (N = 197); and for self-defining memories in Study 3 (N = 262). The explanatory factor analyses performed for each memory type demonstrated the consistency of the AMCQ factor structure across all memory types; while a confirmatory factor analysis on the data garnered from all three studies supported the constructs for the autobiographical memory characteristics defined by the researchers. The AMCQ consists of 63 items and 14 factors, and the internal consistency values of all 14 scales were ranged between .66 and .97. The relationships between the AMCQ scales related to gender and individual emotions, as well as the intercorrelations among the scales, were consistent with both theoretical expectations and previous findings. The results of all the three studies indicated that this new instrument is a reliable and robust measure for memory phenomenology.     

Priming voluntary autobiographical memories: Implications for the organisation of autobiographical memory and voluntary recall processes

The goal of this study was to show that voluntary autobiographical memories could be primed by the prior activation of autobiographical memories. Three experiments demonstrated voluntary memory priming with three different approaches. In Experiment 1 primed participants were asked to recall memories from their elementary school years. In a subsequent memory task primed participants were asked to recall memories from any time period, and they produced significantly more memories from their elementary school years than unprimed participants. In Experiment 2 primed participants were asked to recall what they were doing when they had heard various news events occurring between 1998 and 2005. Subsequently these participants produced significantly more memories from this time period than unprimed participants. In Experiment 3 primed participants were asked to recall memories from their teenage years. Subsequently these participants were able to recall more memories from ages 13–15 than unprimed participants, where both had only 1 second to produce a memory. We argue that the results support the notion that episodic memories can activate one another and that some of them are organised according to lifetime periods. We further argue that the results have implications for the reminiscence bump and voluntary recall of the past.

Characterizing the subjective experience of episodic past,future, and counterfactual thinking in healthy younger and older adults

Recent evidence demonstrates remarkable overlap in the neural and cognitive mechanisms underlying episodic memory, episodic future thinking, and episodic counterfactual thinking. However, the extent to which the phenomenological characteristics associated with these mental simulations change as a result of ageing remains largely unexplored. The current study employs adapted versions of the Memory Characteristics Questionnaire and the Autobiographical Interview to compare the phenomenological characteristics associated with both positive and negative episodic past, future, and counterfactual simulations in younger and older adults. Additionally, it explores the influence of perceived likelihood in the experience of such simulations. The results indicate that, across all simulations, older adults generate more external details and report higher ratings of vividness, composition, and intensity than young adults. Conversely, younger adults generate more internal details across all conditions and rated positive and negative likely future events as more likely than did older adults. Additionally, both younger and older adults reported higher ratings for sensory, composition, and intensity factors during episodic memories relative to future and counterfactual thoughts. Finally, for both groups, ratings of spatial coherence and composition were higher for likely counterfactuals than for both unlikely counterfactuals and future simulations. Implications for the psychology of mental simulation and ageing are discussed.     

Retrieval process of overgeneral memory and the capture and executive control hypothesis: using Autobiographical Memory Test with thought sampling

ABSTRACT

The retrieval process for underlying overgeneral autobiographical memory remains unclear. In this study, we identified what leads to self-referential and categoric thoughts and examined the influence error-monitoring ability has on the reporting of categoric memories. We also examined whether cue self-relevance and/or executive control task performance are related to the number of specific memories reported. Using thought sampling, 94 college students completed the Autobiographical Memory Test, as well as a verbal fluency task and a depression scale. The results indicated that depressive symptoms and negative highly self-relevant cues were associated with self-referential/categoric thoughts during memory retrieval. Further, preceding self-referential/categoric thoughts and low error-monitoring ability predicted immediate after-reporting of categoric memories. Simultaneously, highly self-relevant cues and executive control task performance predicted the reporting of many specific memories. Subdividing the retrieval process and examining the process involved in depression are essential.     

语文学习困难儿童的短时记忆、工作记忆和加工速度

短时记忆、工作记忆和加工速度反映了不同的认知加工.采用多因素混合实验设计,在严格控制条件下,比较了语文学习困难和控制组儿童的工作记忆、短时记忆和加工速度的差异.结果发现,与控制组相比,语文学习困难儿童在工作记忆、短时记忆和加工速度方面均存在明显的不足,但短时记忆和加工速度不能解释不同能力组之间的差异,语文学习困难儿童的缺陷在于工作记忆能力的下降.工作记忆的缺陷在于言语工作记忆的不足,与视空间工作记忆能力无关,语文学习困难与特定的工作记忆(言语工作记忆)能力的不足有关.工作记忆缺陷的原因在于存储能力的不足,而不是加工效率的缺陷造成的.     

Children's Testimony: A Review of Research on Memory for Past Experiences

This review of children's testimony focuses on research related to memory for past experiences. The aspects of the memory system that are involved in testimony are discussed and the development of autobiographical memory is examined. Relevant research findings are summarized in the context of an information-processing model of memory and the implications of this work for clinical practice are outlined. We conclude that (1) under certain conditions, even very young children can remember and report past experiences with some accuracy over very long periods of time; (2) substantial and significant developmental differences have been demonstrated in children's abilities to provide eyewitness testimony; (3) children can be influenced in a variety of ways to provide complete and elaborated reports of events that never occurred; and (4) even experts cannot always tell the difference between true and false reports.

Moral Learning,Rationality, and the Unreliability of Affect

James Woodward and John Allman [2007, 2008] and Peter Railton [2014, 2016] argue that our moral intuitions are products of sophisticated rational learning systems. I investigate the implications that this discovery has for intuition-based philosophical methodologies. Instead of vindicating the conservative use of intuitions in philosophy, I argue that what I call the rational learning strategy fails to show philosophers are justified in appealing to their moral intuitions in philosophical arguments without giving reasons why those intuitions are trustworthy. Despite the fact that our intuitions are outputs of surprisingly sophisticated learning mechanisms, we do not have reason to unreflectively trust them when offering arguments in moral philosophy.     

学习和记忆的无意识研究

内隐学习和内隐记忆的研究代表了人类学习和记忆的无意识过程。在过去的40年里,内隐学习和内隐记忆的研究经历了：研究对象从人工材料走向真实生活,理论观点从分离走向协同,研究方法从单一走向多样化,以及人工神经网络模型中学习和记忆过程的模拟等。它不仅对学习和记忆本身的心理机制得到了更多的理解,而且还为整个心理学特别是认知心理学的研究开辟了广阔的前景。具体表现为多重记忆的划分、无意识研究的异军突起、研究方法的突破扩展和交叉学科的融会贯通     

Moral emotions and the envisaging of mitigating circumstances for wrongdoing

Anger may be more responsive than disgust to mitigating circumstances in judgements of wrongdoing. We tested this hypothesis in two studies where we had participants envision circumstances that could serve to mitigate an otherwise wrongful act. In Study 1, participants provided moral judgements, and ratings of anger and disgust, to a number of transgressions involving either harm or bodily purity. They were then asked to imagine and report whether there might be any circumstances that would make it all right to perform the act. Across transgression type, and controlling for covariance between anger and disgust, levels of anger were found to negatively predict the envisioning of mitigating circumstances for wrongdoing, while disgust was unrelated. Study 2 replicated and extended these findings to less serious transgressions, using a continuous measure of mitigating circumstances, and demonstrated the impact of anger independent of deontological commitments. These findings highlight the differential relationship that anger and disgust have with the ability to envision mitigating factors.     

Delayed,But Not Immediate,Feedback After Multiple-Choice Questions Increases Performance on a Subsequent Short-Answer,But Not Multiple-Choice,Exam: Evidence for the Dual-Process Theory of Memory

Three experiments, two performed in the laboratory and one embedded in a college psychology lecture course, investigated the effects of immediate versus delayed feedback following a multiple-choice exam on subsequent short answer and multiple-choice exams. Performance on the subsequent multiple-choice exam was not affected by the timing of the feedback on the prior exam; however, performance on the subsequent short answer exam was better following delayed than following immediate feedback. This was true regardless of the order in which immediate versus delayed feedback was given. Furthermore, delayed feedback only had a greater effect than immediate feedback on subsequent short answer performance following correct, confident responses on the prior exam. These results indicate that delayed feedback cues a student's prior response and increases subsequent recollection of that response. The practical implication is that delayed feedback is better than immediate feedback during academic testing.
