以故事情境为实验材料,采用学习再认实验范式,通过操纵再认靶词与故事情境的关联性考察了情境故事对关联虚假记忆和真实再认神经活动的影响。结果发现:在记忆再认的熟悉性加工和回想性加工阶段,虚假记忆与真实记忆所诱发FN400和LPC成分走向一致;在额叶后提取阶段,虚假再认所诱发的晚慢成分波幅大于真实再认。结果说明:情境性关联虚假记忆与真实记忆表现出相似的熟悉性和回想性加工,但在后期需耗费额外的加工资源进行成功的提取。  相似文献

通过调查得到个体对日常情境中前瞻记忆失败的6种归因,在此基础上,编制12个日常生活中前瞻记忆失败的情境故事,让124名大学生被试进行归因,以确定事件重要性、人际关系和过错者身份对日常情境中前瞻记忆失败归因的影响。结果表明,被试对不重要事件的前瞻记忆失败归因为“主观无意”,重要事件归因为“主观故意”;在对事件后果和过错者人品判断时具有“对己严格”和“对人宽容”的归因特点;对包含亲子关系的前瞻记忆失败者进行责任较轻的归因与后果判断,在重要事件情境中,对包含朋友关系的前瞻记忆失败者进行责任较重的归因与后果判断。  相似文献

采用DRM范式研究学习阶段不同的注意水平对关联性记忆错觉的影响。结果表明随着注意水平的降低,对学过项目的正确再认率显著下降。对关键诱饵的虚假再认率不易受注意分散的影响。正确再认和虚假再认的记得成分相似,但知道成分的变化趋势不同。虚假再认比正确再认的感知觉细节少。  相似文献

本研究采用DRM范式,探讨了生命性对真实和虚假记忆的影响。实验1使用类别呈现词语强化类别加工,实验2伪随机呈现词语弱化类别加工并进行即时及延时探测。结果发现:(1)当强化类别加工时,生命性和类别对击中率有相类似的促进效应;(2)当弱化类别加工并进行即时探测时,生命性对击中率的促进作用最强;(3)类别效应促进真实记忆和虚假记忆,但生命性效应仅促进了真实记忆,而不影响虚假记忆的产生;(4)在即时与延时探测中均发现类别效应和生命性效应。本研究证明了:(1)生命性效应的作用机制不同于类别效应;(2)生命性效应对真实和虚假记忆的作用机制不同;(3)类别效应和生命性效应的存在时效长达24小时,但是生命性效应的衰退速度较快。  相似文献

前瞻记忆年老化研究的自然情境和实验室情境比较   总被引:1,自引:0,他引:1       下载免费PDF全文
年龄—前瞻记忆矛盾现象在实验室情境和自然情境研究中普遍存在。当任务设置为日常情境时, 前瞻记忆不受年龄影响或随年龄增长而促进, 前瞻记忆成绩可能受人格、生活方式、任务材料、提示等因素的影响; 当任务是实验室情境设置时, 与年轻被试相比, 老年被试前瞻记忆成绩一般都较差, 前瞻记忆成绩可能受回溯记忆负载、线索类型和策略控制加工的需求等因素的影响。年龄-前瞻记忆矛盾现象可能来自于环境与意向的社会性特征、认知资源分配策略等方面的原因。最后, 从被试控制、任务材料的设置、动机因素的探索等方面对今后的研究提出建议和展望。  相似文献

以往研究发现类别空间关系表征具有左半球激活优势,但在行为表现中是否存在对侧化的右侧化优势尚且不明确。本研究采用两个被试内实验,探讨空间记忆的行为表现是否具有右侧化优势以及这种优势是否受威胁情境的影响。实验1被试学习完一幅模拟地图中物体位置关系后进行相对位置判断任务,结果发现了显著的空间行为反应右侧化优势。实验2使被试在威胁情境中完成相同任务,发现右侧化优势消失。实验表明类别性空间记忆的行为表现具有右侧化优势,且具有情境不稳定性,这为空间记忆的偏侧化研究提供了一定的行为实验证据。  相似文献

We examined the relation between emotion and susceptibility to misinformation using a novel paradigm, the ambiguous stimuli affective priming (ASAP) paradigm. Participants (N = 88) viewed ambiguous neutral images primed either at encoding or retrieval to be interpreted as either highly positive or negative (or neutral/not primed). After viewing the images, they either were asked misleading or non-leading questions. Following a delay, memory accuracy for the original images was assessed. Results indicated that any emotional priming at encoding led to a higher susceptibility to misinformation relative to priming at recall. In particular, inducing a negative interpretation of the image at encoding led to an increased susceptibility of false memories for major misinformation (an entire object not actually present in the scene). In contrast, this pattern was reversed when priming was used at recall; a negative reinterpretation of the image decreased memory distortion relative to unprimed images. These findings suggest that, with precise experimental control, the experience of emotion at event encoding, in particular, is implicated in false memory susceptibility.  相似文献

In three experiments, we examined the memory-undermining effects of daydreaming for (un)related stimuli. In Experiments 1 and 2, we tested whether daydreaming fosters forgetting of semantically interrelated material and hence, catalyzes false memory production. In Experiment 3, we examined the memory effects of different daydreaming instructions. In Experiment 1, daydreaming did not undermine correct recall of semantically interrelated words, nor did it affect false memories. In Experiment 2, we again failed to find that daydreaming exerted memory-undermining effects a. In Experiment 3, no memory effects were obtained using different daydreaming instructions. Together, our studies fail to show appreciable memory-undermining effects of daydreaming.  相似文献

When presented with novel but semantically related elements after learning verbal material, healthy participants tend to endorse these items as previously learned. This reflects the normal integration and association of novel verbal information into long-term memory. How obstructive sleep apnoea (OSA) negatively impacts verbal memory performance, and whether deficits are reversible following positive airway pressure (PAP) treatment, remain elusive. We investigated immediate and delayed OSA- and PAP treatment-related effects on verbal memory integration, using a false memory paradigm. Twenty-three patients with OSA learned lists of words semantically related to target non-presented words (1) at baseline after a polysomnography diagnosis night, (2) after a consecutive polysomnography night under PAP titration, and (3) after three months of compliant PAP treatment. At each session, participants learned 10 different lists of words, each list comprising 15 semantically related items. They had then to recognize 15 minutes later (after an intermediate vigilance task) previously learned words within a list including studied words (learned), unstudied but semantically related items (lures), and non-related unstudied items (controls). Sleep quality and fatigue questionnaires, and psychomotor vigilance tests (PVT) were administered at each session. PAP treatment led to OSA remission and improvement in objective and subjective sleep quality. Crucially, recognition of learned and lure words increased after the first night under treatment and remained stable three months later, suggesting successful memory integration and restoration of semantic processes. No treatment-related outcome was found on PVT performance. OSA exerts a detrimental but PAP-reversible effect on verbal learning and semantic memory integration mechanisms underlying the acquisition of novel memory representations.  相似文献

While previous research has suggested that adults with a history of childhood sexual abuse may be more prone to produce false memories, little is known about the consequences of childhood neglect on basic memory processes. For this reason, the authors investigated how a group of women with a history of childhood emotional neglect (CEN) and diagnosed with recurrent Major Depressive Disorder (MDD) performed on the Deese–Roediger–McDermott paradigm in comparison to control groups. The results indicated that women with MDD and CEN were actually less prone to produce false memories relative to both women with MDD but no CEN and healthy women without MDD and any form of childhood maltreatment. These findings were explained in terms of the inability to extract/retrieve gist memories that support false recognition of critical lures, an explanation that seems to fit well with emerging MRI findings linking childhood neglect to reduced volume of brain regions associated to memory function.  相似文献

Sex hormones are increasingly implicated in memory formation. Recent literature has documented a relationship between hormones and emotional memory and sex differences, which are likely related to hormones, have long been demonstrated in a variety of mnemonic domains, including false memories. Hormonal contraception (HC), which alters sex hormones, has been associated with a bias towards gist memory and away from detailed memory in women who use it during an emotional memory task. Here, we investigated whether HC was associated with changes in susceptibility to false memories, which may be related to the formation of gist memories. We tested false memory susceptibility using two well-validated false memory paradigms: the Deese–Roediger–McDermott (DRM) task, and a story-based misinformation task. We found that hormonal contraceptive users were less susceptible to false memories compared to non-users in the misinformation task, and no differences were seen between groups on the DRM task. We hypothesise that the differences in false memories from the misinformation task may be related to hormonal contraceptive users' memory bias away from details, towards gist memory.  相似文献

Exposing older adults to ageing stereotypes can reduce their memory for studied information—a phenomenon attributed to stereotype threat—but little is known about stereotype effects on false memory. Here, we assessed ageing stereotype effects on the Deese-Roediger-McDermott false memory illusion. Older adults studied lists of semantically associated words, and then read a passage about age-related memory decline (threat condition) or an age-neutral passage (control condition). They then took a surprise memory test with a warning to avoid false recognition of non-studied associates. Relative to the control condition, activating stereotype threat reduced the recognition of both studied and non-studied words, implicating a conservative criterion shift for associated test words. These results indicate that stereotype threat can reduce false memory, and they help to clarify mixed results from prior ageing research. Consistent with the regulatory focus hypothesis, threat motivates older adults to respond more conservatively when error-prevention is emphasised at retrieval.  相似文献
