依赖于唤醒与效价的情绪记忆增强效应：自动与控制加工*

情绪记忆增强(Emotionally Enhanced Memory, EEM)效应受到刺激的唤醒度和效价的影响。Kensinger 等人提出依赖于唤醒的 EEM 效应与自动加工相联系,依赖于效价的 EEM 效应与控制加工相联系。然而现有研究并不能为这一假设提供充分的证据。本研究的三个实验采用学习--再认范式和 DA 范式(divided attention paradigm)相结合的方法,分别考察了在两种注意条件下依赖于唤醒和依赖于效价的EEM 效应在编码阶段的加工机制。结果发现,中性词、正性非唤醒词、负性非唤醒词在集中注意条件下的记忆再认成绩显著高于分散注意条件下的记忆再认成绩;正性唤醒词在集中注意条件下的记忆再认成绩也显著高于分散注意条件下的记忆再认成绩,但负性唤醒词的记忆再认成绩在两种注意条件下不存在显著差异。这表明依赖于效价的 EEM 效应与控制加工相联系,而依赖于唤醒的 EEM 效应并不总是与自动加工相联系,其加工还受到情绪效价的调节,对于负性刺激,依赖于唤醒的 EEM 效应与自动加工相联系;对于正性刺激,依赖于唤醒的EEM效应则与控制加工相联系。

不同语义水平下参照方式、情绪效价和特质评价对记忆的影响

为了探索影响记忆的深层次因素及其作用机制,采用内隐实验范式,考察了不同语义水平下参照方式、情绪效价和特质评价对记忆的影响。结果发现,参照方式、情绪效价和特质评价分别对记忆产生了显著的影响;在不同语义水平下,自我相关的特质词和非特质词的记忆优势表现在不同的再认提取阶段;个体对自我相关的消极词表现出显著的记忆优势;参照方式、情绪效价和特质评价的交互作用不显著。结果表明,参照方式、情绪效价和特质评价是对记忆产生影响的独立因素,但参照方式对记忆的影响受到情绪效价和特质评价的制约。

不同记忆提取条件下的自我参照效应

通过操纵记忆提取的条件,本实验比较了自我参照、他人参照和无参照(褒义/贬义)任务下的记忆效果.结果发现:(1)自我参照编码在再认测验中出现了显著的提取优势(F(2.41)=6.097,p<0.01);(2)自我参照编码在颜色一致/不一致判断中未出现显著的提取优势(F(2,41)=1.039,p=0.363);(3)再认测验中,颜色不一致旧词的再认辨别力高于一致条件(F(1,41)=3.139,p=0.084).     

自尊与记忆偏向的关系

采用2（外显自尊：高、低）×2（内隐自尊：高、低）×2（编码深度：浅、深）×3（词汇效价：积极、中性、消极）混合设计,考察了89名不同自尊类型的大学生在不同编码深度下对不同效价形容词的再认记忆。结果发现：（1）在浅水平编码组中,低内隐自尊被试比高内隐自尊被试有更强的积极记忆偏向,而高低不同水平的外显自尊者对于词语记忆偏向没有显著差异;（2）在深程度编码组中不同自尊水平影响被试对积极词的无意识提取;（3）所有被试均有积极记忆偏向。     

初中生自尊的认知加工偏向效应研究

探讨了初中生自尊的认知加工偏向效应。结果发现：高自尊初中生对积极词具有显著的注意偏向效应,低自尊初中生对积极词和消极词均不存在注意偏向效应;当对比图片为高兴－生气或高兴－中性表情时,高自尊初中生对高兴表情均存在显著的注意偏向效应,当对比图片为高兴－生气时,低自尊初中生对生气表情产生明显的注意偏向效应;高自尊组与低自尊组初中生分别对与自我有关的正向、负向形容词存在显著的记忆偏向效应。     

不同提取条件下中性抽象名词的自我选择权效应

采用中性抽象名词探测在再认测试和自由回忆条件下的自我选择权效应。实验一采用选择与迫选的方式考察抽象名词在再认条件下的自我选择权效应;实验二进一步验证被试在我选择和他选择条件下对抽象名词的自由回忆的差异。结果表明:无论在再认测试还是自由回忆测试,被试对自我选择的抽象名词的记忆数量都显著高于迫选和他人选择条件下的抽象名词记忆的数量,中性抽象名词表现出了自我选择权效应,拓展了前人使用假词时在自由回忆条件下未表现出自我选择权效应。因此,自我选择权效应在自由回忆条件下可以存在于抽象名词的水平上。     

四岁儿童的自我参照效应研究

本研究通过两个实验探讨4岁儿童的自我参照效应。实验1与实验2分别采用3(4岁、5岁与7岁儿童)×2(自我参照与他人参照)与2(3岁与4岁儿童)×2(自我参照与他人参照)的混合设计。120名被试对物品进行所有权(ownership)识别并报告"这是我的××"或"这是李明的××",然后将图片放入相应的纸盒并再次报告,两分钟后进行自由回忆。结果显示:(1)自我参照条件下4岁组、5岁组与7岁组儿童自由回忆率有显著差异,他人参照条件下没有差异;(2)自我参照条件下4岁组儿童的自由回忆率显著高于3岁组,他人参照条件下没有差异。这说明,4岁儿童已经具有自我参照效应,同时,随着年龄的增长,自我参照条件下的自由回忆率呈现递增趋势,表明儿童自我参照效应的发展性特点。     

实际亲密度对恋人参照效应的影响

为考察实际亲密度对恋人参照效应的影响,采用自我参照研究中的R/K判断范式和实际亲密度与应有亲密度量表对68名（35名男性,33名女性）处于恋爱关系中的被试施测。结果发现：在R反应上,实际亲密度与参照条件交互作用显著,高实际亲密度组表现出恋人参照效应,而低实际亲密度组未表现出恋人参照效应;性别与参照条件交互作用显著,女性整体上表现出恋人参照效应,而男性整体上未表现出恋人参照效应;应有亲密度与参照条件交互作用不显著;在K反应上,所有效应均不显著。研究证明了在自我参照范式中,自我是否呈现出恋人参照效应可能受实际亲密度的影响,并存在性别差异。结果提示,在他人参照效应的研究中,需将实际亲密度和性别变量考虑进来     

Older adults show a self-reference effect for narrative information

The self-reference effect (SRE), enhanced memory for information encoded through self-related processing, has been established in younger and older adults using single trait adjective words. We sought to examine the generality of this phenomenon by studying narrative information in these populations. Additionally, we investigated retrieval experience at recognition and whether valence of stimuli influences memory differently in young and older adults. Participants encoded trait adjectives and narratives in self-reference, semantic, or structural processing conditions, followed by tests of recall and recognition. Experiment 1 revealed an SRE for trait adjective recognition and narrative cued recall in both age groups, although the existence of an SRE for narrative recognition was unclear due to ceiling effects. Experiment 2 revealed an SRE on an adapted test of narrative recognition. Self-referential encoding was shown to enhance recollection for both trait adjectives and narrative material in Experiment 1, whereas similar estimates of recollection for self-reference and semantic conditions were found in Experiment 2. Valence effects were inconsistent but generally similar in young and older adults when they were found. Results demonstrate that the self-reference technique extends to narrative information in young and older adults and may provide a valuable intervention tool for those experiencing age-related memory decline.     

The effects of ageing and divided attention on the self-reference effect in emotional memory: Spontaneous or effortful mnemonic benefits?

The self-reference effect (SRE) is a powerful memory advantage associated with encoding in reference to the self (e.g., Rogers, Kuiper, & Kirker, 1977). To explore whether this mnemonic benefit occurs spontaneously, the current study assessed how ageing and divided attention affect the magnitude of the SRE in emotional memory (i.e., memory for emotional stimuli). The sample included a young Full Attention group (young-FA), a young Divided Attention group (young-DA), and an older adult group. The division of attention was manipulated at encoding where participants incidentally studied positive, negative, and neutral trait adjectives in either a self-reference (i.e., rating how well each word describes themselves) or an other-reference condition (i.e., rating how well each word describes another person). Memory for these words was assessed with both recall and recognition tasks. The results from both tasks demonstrated equivalent SRE for all three groups across emotional valence categories of stimuli, suggesting that the SRE is a spontaneous, effortless, and robust effect in memory.     

高边缘性人格障碍特质者负性沉浸的自我反思倾向

采用自我参照范式考察边缘性人格障碍(BPD)的自我反思特点。实验1对比高、低BPD特质被试在自我和姓名参照条件下正负性词汇的再认成绩,发现高BPD特质者在自我参照条件下的负性词汇记忆成绩显著高于低BPD特质组。实验2对高BPD特质被试进行正念自我反思训练,结果发现相对于对照组,训练组在自我参照条件下负性词汇的记忆成绩显著降低。高BPD特质者的自我反思存在负性沉浸倾向,且正念自我反思训练可以改善该倾向。     

自我参照对情绪性记忆定向遗忘的影响

关于自我参照效应的研究大多从信息编码角度考察自我参照的加工优势, 但作为记忆过程的另一重要方面, 自我参照对遗忘影响的研究较少。遗忘自身经历的情绪性记忆是日常生活中的常见现象。研究采用项目法定向遗忘范式(item-method directed forgetting)考察了自我参照对情绪性记忆定向遗忘的影响。实验一和实验二的结果都表明参照方式会影响定向遗忘：自我参照条件下的材料会发生定向遗忘; 而他人参照条件下的材料不会发生定向遗忘, 两种参照方式下材料间区辨性的不同是导致这一现象的原因。此外, 实验二采用回忆测试发现：自我参照对不同效价的情绪性记忆定向遗忘产生了不同影响, 而自我提升(self-enhancement)动机在其中起着重要的调节作用。     

Source memory that encoding was self-referential: the influence of stimulus characteristics

Decades of research suggest that encoding information with respect to the self improves memory (self-reference effect, SRE) for items (item SRE). The current study focused on how processing information in reference to the self affects source memory for whether an item was self-referentially processed (a source SRE). Participants self-referentially or non-self-referentially encoded words (Experiment 1) or pictures (Experiment 2) that varied in valence (positive, negative, neutral). Relative to non-self-referential processing, self-referential processing enhanced item recognition for all stimulus types (an item SRE), but it only enhanced source memory for positive words (a source SRE). In fact, source memory for negative and neutral pictures was worse for items processed self-referentially than non-self-referentially. Together, the results suggest that item SRE and source SRE (e.g., remembering an item was encoded self-referentially) are not necessarily the same across stimulus types (e.g., words, pictures; positive, negative). While an item SRE may depend on the overall likelihood the item generates any association, the enhancing effects of self-referential processing on source memory for self-referential encoding may depend on how embedded a stimulus becomes in one’s self-schema, and that depends, in part, on the stimulus’ valence and format. Self-relevance ratings during encoding provide converging evidence for this interpretation.     

Affective valence and the self‐reference effect: Influence of retrieval conditions

Positive trait information is typically better recalled than negative trait information when encoded in reference to the self, but not when encoded in reference to someone else or when processed for general meaning. This study examined whether this influence of affective meaning is modulated by retrieval conditions. Participants encoded positive and negative trait adjectives in reference to themselves or to a celebrity. They were then presented with either a free‐recall task (Experiment 1) or a recognition memory task (Experiment 2). Positive adjectives were better recalled than negative adjectives, but only when they were encoded in reference to the self. In contrast, encoding condition and valence did not interact in the recognition memory task. Taken together, these findings suggest that the difference in memory between positive and negative self‐referent information is due, at least in part, to a control exerted on memory retrieval.     

The self and recollective experience

Three experiments investigated the hypothesis that self-reference at encoding increases the probability of recollective experience in recognition memory. In all three experiments separate groups of subjects studied words naming personality traits. One group judged the self-relevance of the traits, the other groups performed orientating tasks low in self-reference. In a recognition test subjects first identified old items and then indicated which of these were accompanied by recollective experience ('remember' responses) and which were recognized on some other basis ('know' responses). No reliable differences in overall recognition performance between self-referent and semantic encoding tasks were observed. However, subjects who encoded trait adjectives with reference to the self produced reliably more remember responses and few know responses than subjects who had encoded the items in the low self-referent tasks. Experiment 1 demonstrated a self-reference effect in recognition accompanied by recollective experience after 1-hour retention interval, while Experiment 2 found this effect to persist over a 24-hour retention interval. Experiment 3 demonstrated that this self-reference effect is obtained under incidental as well as under intentional learning conditions. Taken together these findings demonstrate the importance of self-reference as a factor in determining the likelihood that recognition judgements will be accompanied by recollective experience.     

Individual differences in cognitive control on self-referenced and other-referenced memory

Self-referenced information is better recalled than other-referenced information – a mnemonic advantage known as the “self-reference effect” (SRE). By using a modified version of the “think/no-think” (TNT) paradigm (Anderson & Green, 2001), this study examined the effects of cognitive control on the SRE after the encoding stage. The results indicate that individual differences in personality traits and affective states strongly modulated the SRE after the TNT phase. For individuals high in negative cognitive style, an ironic enhancement of negative self-referenced memory produced a “maladaptive” SRE: better memory for negative self-referenced information than for negative other-referenced information, when trying to suppress that information. Before the TNT phase, instead, the SRE was characterized by the opposite bias. These results indicate that (1) the SRE is strongly affected by cognitive control after encoding, and (2) also in the non-clinical population, dysfunctional cognitive control can transform the SRE into a “maladaptive” memory bias.
