成人依恋可以在依恋回避和依恋焦虑两个维度进行分析。不安全依恋的个体在依恋关系中持续感受到一种不安全感,因此个体往往采用心理防御策略来摆脱这种不安全感。对于许多不愉快的事件,个体常常也会采用类似的防御策略进行抑制,以减少自身的消极体验。主动遗忘是指个体有意识地避免回想某一目标对象而导致的遗忘现象,其可能与高回避个体的停用策略十分相似。为探讨对于依恋相关的记忆内容,高回避个体是否能够成功进行主动遗忘以规避负面情绪,或是防御失败引起依恋系统激活,反而更多回忆起相关记忆内容,本实验采用Think/No-Think(TNT)范式进行研究,以依恋相关故事作为对被试的依恋启动操作,设计了2(启动:依恋启动vs.依恋未启动)×3(主动遗忘:Think vs.No-Think vs.Baseline)×2(依恋维度得分:高vs低)混合设计研究不同依恋类型主动遗忘能力的影响。实验结果显示,TNT操作与回避类型与启动操作的交互作用显著,高依恋回避个体在受到依恋相关启动时表现出优秀的主动遗忘能力,而在未受到启动时则不能有效地遗忘依恋相关负性词对; 而低依恋回避个体则表现相反,在受到启动材料威胁时无法成功主动遗忘,而在未受启动条件下可以成功遗忘要求内容。对于不同焦虑类型的被试来说,其主动遗忘能力与启动操作无关,高焦虑类型被试表现出更强的主动遗忘能力,并从依恋内部工作模型角度进行了分析。 相似文献

在社会互动的提取小组中, 说者的选择性提取可能会导致听者对未提及但相关内容的遗忘, 这被称为社会分享型提取诱发遗忘。本研究实验1首先考察了有无真实他人在场对社会分享型提取诱发遗忘的影响, 结果显示只有在真实他人在场条件下, 该现象才会出现, 说明社会分享型提取诱发遗忘受到听者对自下而上的社会互动情境加工的影响。实验2进一步考察了在他人在场条件下, 个体的抑制控制能力对社会分享型提取诱发遗忘的影响, 结果显示该现象只与其作为说者时的个体提取诱发遗忘效应大小有关, 提示了社会分享型提取诱发遗忘与个体提取诱发遗忘过程类似, 都会受到个体自上而下的排除竞争项目侵入记忆的无意抑制能力的影响。研究结果为理解人际交流情形下个体记忆的形成与改变提供了重要启发。 相似文献

想/不想范式(Think/No-think,TNT)是基于go/no-go范式提出来的用于研究动机性遗忘过程的实验范式,主要过程是指个体对于记忆的提取抑制可以导致随后该记忆的遗忘。近年来TNT范式的大量行为学研究都一致性地发现记忆提取抑制可以产生负性控制效应,验证了在实验室情境下对动机性遗忘进行研究的可行性。其中,负性控制效应指的是压抑条件的项目相对于基线条件的项目的回忆量有显著降低。关于动机性遗忘发生的神经机制的探讨已积累了大量的研究证据,总结脑电(EEG)和功能核磁共振(f MRI)两个模态的研究,我们提出了动机性遗忘发生的多模态功能网络模型。最后,在该模型的基础上,我们展望了TNT范式未来的研究方向,其中特别注意到同步EEG-f MRI技术的应用有望为我们揭示出记忆提取抑制导致的动机性遗忘发生的动态过程。 相似文献

当面对不愉快的提醒时, 人们通常会试图阻止那些不想要的记忆出现在脑海中。先前的研究表明, 抑制不想要的记忆的检索会降低这些记忆的可及性, 引起遗忘, 这一效应称为抑制引起的遗忘(suppression- induced forgetting, SIF)。SIF的神经机制涉及右背外侧前额叶皮层和额中回的激活增加, 以及海马的激活受到抑制。SIF的程度受记忆材料的情绪效价、个体的病理性情绪状态和训练的影响。未来研究应在深入了解SIF神经机制的基础上, 考虑如何提高临床病理性记忆的SIF效果, 以达到治疗目的。 相似文献

基于视觉通道的研究表明,人们可以通过主动抑制记忆提取而实现遗忘。但目前对跨通道的主动遗忘尚缺乏探讨。本研究以声音为记忆线索,以文字为目标记忆,采用“想/不想”范式,探究主动遗忘在跨视听通道条件下的可行性。结果发现,“不想”条件下目标记忆的回忆率低于基线条件,主动遗忘发生。此外,我们通过分离任务指令和记忆线索的呈现时间,在中央区域的ERP中发现了记忆抑制的期待效应;并在额叶观察到“不想”条件下晚期正成分的增强,反映了持续的抑制控制过程。本研究不但验证了跨视听通道主动遗忘的可能性,而且第一次从ERPs角度分离了跨通道遗忘相关的期待加工和抑制控制过程。 相似文献

ABSTRACTWe investigated the duration of suppression-induced forgetting (SIF), and the extent to which retrieval suppression differs between negative and neutral memories. We further examined if SIF was differently affected by sleep versus wake during the delay interval between retrieval suppression and re-test. Fifty participants first learned to associate neutral words with either neutral or negative images. Then, a subset of the words was shown again, and participants were asked to either recall (Think), or to suppress retrieval of (No-Think) the associated images. Finally, a memory test for all items was performed either immediately after the Think/No-Think (T/NT) phase (No Delay), or after a 3.5?h delay interval containing either sleep or wake. Results revealed a SIF effect only in the No Delay group, indicating that this forgetting effect dissipates already after a 3.5?h delay interval. Negative items were experienced as more intrusive than neutral ones during the T/NT phase. 相似文献

Research on retrieval suppression has produced varying results concerning whether negatively valenced memories are more or less suppressible than neutral memories. This variability may arise if, across studies, participants adopt different approaches to memory control. Cognitive and neurobiological research points to two mechanisms that achieve retrieval suppression: thought-substitution and direct suppression (Benoit & Anderson, 2012; Bergström, de Fockert, & Richardson-Klavehn, 2009). Using the Think/No-think paradigm, this study examined whether participants can inhibit neutral and negatively valenced memories, using a uniform direct suppression strategy. Importantly, when strategy was controlled, negative and neutral items were comparably inhibited. Participants reported high compliance with direct suppression instructions, and success at controlling awareness predicted forgetting. These findings provide the first evidence that direct suppression can impair negatively valenced events, and suggest that variability in forgetting negative memories in prior studies is unlikely to arise from difficulty using direct suppression to control emotionally negative experiences. 相似文献

抑郁症认知障碍的突出表现之一为患者的负性记忆偏向。已有研究常关注患者对负性信息自下而上的选择性注意,往往忽略了自上而下执行控制障碍对记忆的影响。近年研究提示,抑郁症患者和抑郁状态个体的记忆抑制缺陷在其负性记忆偏向的形成和维持中起到了重要作用,无法有效地主动抑制负性记忆可能是患者持续性负性反刍的主要原因。从抑郁症自上而下的执行控制缺陷入手,研究患者的记忆抑制障碍与其主要症状-负性反刍间的相关性,不仅能从理论上丰富Beck的抑郁症认知模型,还能指导临床建立更准确的预后评估指标,同时制定更有效的治疗方案。本文分别介绍了健康成人及抑郁症患者和抑郁状态个体的记忆抑制研究现状,并就当前在抑郁人群研究领域亟待解决的三个问题进行了探讨。 相似文献

In 6 experiments, the authors investigated list-method directed forgetting of recently recalled autobiographical memories. Reliable directed forgetting effects were observed across all experiments. In 4 experiments, the authors examined the impact of memory valence on directed forgetting. The forget instruction impaired recall of negative, positive, and neutral memories equally, although overall, participants recalled fewer unemotional memories than emotional memories. The preexisting organization of memories enhanced the directed forgetting effect, and a release from forgetting occurred only when the forgotten memories were directly cued. The authors discuss the roles of emotion, retrieval dynamics, and organization in these effects and suggest that the directed forgetting of recently recalled autobiographical memories may reflect the inhibition of recently formed memories of remembering, that is, episodic inhibition. The authors consider the implications of these findings for the control of autobiographical remembering in everyday life. 相似文献

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。 相似文献

Can we control the content of our memory and forget what we do not want to think about by an act of will? If so, is forgetting temporary or permanent, and is it independent of the nature of what we wish to forget? Using Anderson and Green’s (2001) “think/no-think” paradigm with neutral and emotional nouns, we found in agreement with other studies that memory for neutral words was reduced instantly upon repeated attempts at suppression. However, the effect was temporary and vanished after a period of one week, which strongly suggests that intended memory suppression interferes with immediate retrieval but does not lead to long-term forgetting. Furthermore, the amount of training that clearly reduced immediate recall of neutral items did not at all reduce recall of emotional items. This finding is in accordance with the notion that emotional items have a higher degree of salience and tend to attract more attention than neutral items. 相似文献

Two diary experiments demonstrated directed forgetting (DF) of autobiographical events, previously observed only for less complex memory items. Using a 2-week diary paradigm, we compared recall between a group of participants who were directed to forget Week 1 memories (forget group) and a group who did not receive a forget instruction (remember group). In Experiment 1, the forget group remembered fewer items from Week 1 than did the remember group. The effect was observed for negative and positive valence events, as well as for high and low emotional intensity events. The effect was replicated in Experiment 2 despite a memorable holiday (Valentine's Day) that occurred during the manipulation week. Forget participants remembered fewer low emotional intensity items in Experiment 2. We conclude that intentional forgetting is a plausible explanation for the loss of some autobiographical memories. 相似文献
