ABSTRACT— An interesting challenge for researchers who study prospective memory is to explain how people recognize environmental events as cues for actions. Whereas some theorists propose that a capacity-consuming monitoring process is the only means by which intentions can be retrieved, we argue that the cognitive system relies on multiple processes, including spontaneous processes that reflexively respond to the presence of target events. We present evidence for the existence of spontaneous retrieval processes and apply the idea of multiple processes to mixed findings on age-related decline in prospective memory.  相似文献

The current study investigated prospective memory (PM) performance in children with attention deficit/hyperactivity disorder (ADHD) and controls and aimed at exploring possible underlying factors of PM performance. Twenty-two children with ADHD and 39 age- and ability-matched typically developing children performed a computerized time-based PM task. As predicted, children with ADHD had fewer correct PM responses than controls. Neither differences in overall ongoing task performance nor, remarkably, differences in overall frequency and accuracy of time monitoring were found. Exploratory analyses suggest that individual differences in time monitoring in the final interval before target times may be related to PM performance in ADHD.  相似文献

采用经典双任务实验范式,探讨前瞻记忆的情绪一致性效应及其理论模型。情绪电影片段诱发被试高兴或悲伤情绪后,观察被试在高兴、悲伤和自然情绪状态下的前瞻记忆任务和当前任务的成绩。结果发现,情绪一致性前瞻记忆出现反转效应,即在高兴背景下前瞻记忆负性词比正性词成绩好,在悲伤背景下前瞻记忆正性词比负性词成绩好。实验结果支持前瞻记忆的注意—搜索模型,不支持自动激活模型。  相似文献

沉思和分心对负情绪和自传体记忆的影响   总被引:1,自引:0,他引:1  
探讨在诱发了抑郁、焦虑、悲伤等负性情绪后,沉思和分心对正常成人的情绪主观报告、生理变化和自传体记忆的作用。64名被试被随机分为两组,用故事和电影短片分别诱发了负性和中性(控制组)两种情绪状态。然后进行随机分组,分别进行分心和沉思的反应任务。测量四组被试的情绪主观报告、生理变化以及多种形式和性质的自传体记忆。结果表明:(1)沉思和分心对这些负情绪的调节作用不显著;(2)沉思引起更多的负性记忆,正性复合指数更小,自传体记忆的具体性更弱。结论:沉思导致更多负性记忆,维持了概括性记忆,更有可能加重已经激活的负情绪  相似文献

不同年龄被试前瞻记忆的特点是前瞻记忆领域研究的热点之一。研究者们运用不同的研究范式和不同的实验条件对这一问题进行了深入探讨,并提出了解释年龄效应的理论观点。这一领域的研究应朝向更具生态效度、实验条件更加标准化的方向进行。  相似文献

前瞻记忆和认知控制是人类认知能力的重要组成部分。Bugg等人(2013)发现前瞻记忆多重加工模型和双重认知控制理论具有共性。此后,越来越多的研究者关注认知控制在意图执行中和执行完成后的作用。本文对近年来关于前瞻记忆与认知控制的研究进行了梳理,发现认知控制对前瞻记忆的完成起支持作用,但二者也在脑机制层面存在差异。本研究能为未来更深入地探讨前瞻记忆的加工机制及生理基础提供新的视角。  相似文献

Up until recently, it had been assumed that attentional biases for negative information do not exist in depression. However studies using post-conscious exposure durations have produced contradictory results. The limitations of common attentional tasks, suitability of stimulus materials and differences in stimulus duration times may have contributed to these inconsistencies. We aimed to address many of these issues and examine attentional responses in major depression at two post-conscious exposure times. We also investigated possible roles for rumination and distraction in increasing and lessening attentional biases for negative information. We used a fully controlled experimental design to test the effects of both induced and trait rumination and distraction on attention in patients with major depression and healthy controls. Attention was assessed using the dot-probe task. The findings revealed an attentional bias for negative information in depressed patients only at the longer post-conscious exposure duration. Furthermore although this bias was not influenced by either induced or trait distraction, it was related to trait rumination. Overall, the results showed that depression is associated with a strategic attentional bias towards negative information and that this bias is stronger in individuals who habitually ruminate.  相似文献

轻度阿尔茨海默症往往伴随着不同程度的前瞻记忆衰退。已有研究以轻度阿尔茨海默症与前瞻记忆衰退的关联程度为主线, 对比了这一关联与“其他认知缺陷疾病-前瞻记忆衰退”、“轻度阿尔茨海默症-回溯记忆衰退”以及“轻度阿尔茨海默症-遗传表达”这三种关联的类似程度。此外, 也有研究涉及到了如何促进轻度阿尔茨海默症患者的前瞻记忆。将来的研究应引入病情程度、前瞻记忆任务类型等变量, 深入探讨轻度阿尔茨海默症与前瞻记忆衰退的关联, 并使用ERP、fMRI等神经生理技术确定轻度阿尔茨海默症患者前瞻记忆衰退的机制。  相似文献

The Prospective and Retrospective Memory Questionnaire (PRMQ) has been shown to have acceptable reliability and factorial, predictive, and concurrent validity. However, the PRMQ has never been administered to a probability sample survey representative of all ages in adulthood, nor have previous studies controlled for factors that are known to influence metamemory, such as affective status. Here, the PRMQ was applied in a survey adopting a probabilistic three-stage cluster sample representative of the population of São Paulo, Brazil, according to gender, age (20–80 years), and economic status (n=1042). After excluding participants who had conditions that impair memory (depression, anxiety, used psychotropics, and/or had neurological/psychiatric disorders), in the remaining 664 individuals we (a) used confirmatory factor analyses to test competing models of the latent structure of the PRMQ, and (b) studied effects of gender, age, schooling, and economic status on prospective and retrospective memory complaints. The model with the best fit confirmed the same tripartite structure (general memory factor and two orthogonal prospective and retrospective memory factors) previously reported. Women complained more of general memory slips, especially those in the first 5 years after menopause, and there were more complaints of prospective than retrospective memory, except in participants with lower family income.  相似文献

近年来有越来越多的心理学家从神经心理学角度对前瞻记忆进行研究,其中涉及较多的是正常被试与脑损伤患者之间的前瞻记忆比较。本文则针对目前关注比较少的精神分裂症这种特殊的脑损伤病人,通过对28名精神分裂症患者与30名正常被试在一定试验条件下进行前瞻记忆研究,试图发现其与正常被试在前瞻记忆的水平、影响因素以及自我评价方面的差异并分析其原因。  相似文献

Previous studies provide clear evidence that visuospatial memory performance in children with attention-deficit/hyperactivity disorder (ADHD) is significantly lower than in typically developing children. In the present study, we investigated a major cause of their low performance using a spatial span test. Possibly, inattention resulting from lack of motivation or interest causes their low performance so that they do not correctly encode targets to be remembered. On the other hand, a deficit in temporary maintenance per se may cause their low performance; that is, their inefficient use of rehearsal during a retention interval may lead to memory traces’ fast decay. Results in this study indicated that children with ADHD could sustain attention during the encoding phase. Furthermore, their performance at delayed recall was significantly lower than immediate recall, but delayed recall did not affect typically developing children's performance. These results provide evidence for the likelihood that a factor causing children with ADHD difficulty in temporarily maintaining visuospatial information is fast decay of memory traces as a result of inefficient use of rehearsal, not inattention in the encoding phase.  相似文献

Bereavement can precipitate symptoms of depression, prolonged grief disorder, and posttraumatic stress disorder. Targeting repetitive negative thought (i.e., worry, rumination) in treatment may help reduce post-loss psychopathology. Yet, evidence on longitudinal associations of depressive rumination and worry with post-loss psychopathology symptoms has been mixed and the directions of effects are still unclear. Recently bereaved adults (78% female) completed questionnaires assessing depressive rumination (brooding), worry, and depression, prolonged grief and posttraumatic stress symptoms 11 times in 1.5 month intervals. We applied random-intercept cross-lagged panel models (RICLPMs) to examine reciprocal within-person associations between worry and psychopathology symptoms, between rumination and these symptoms, and between worry and rumination. Main findings were that worry showed reciprocal relationships with psychopathology symptoms (although worry did not consistently predict prolonged grief symptoms). Depressive rumination was predicted by psychopathology symptoms, but not vice versa. Worry showed reciprocal relations with depressive rumination. Findings suggest that worry may be part of a downward spiral, enhancing psychopathology symptoms following loss, whereas depressive rumination is solely a consequence of such symptoms.  相似文献

前瞻记忆的年老化效应:前瞻成分和回溯成分的调节作用   总被引:1,自引:0,他引:1  
陈思佚  周仁来 《心理学报》2010,42(6):640-650
关注事件性前瞻记忆的年老化,采用基于双重任务的实验室研究范式,实验一控制线索与意向的关联性和线索的显著性操纵概念驱动加工和数据驱动加工过程,比较前瞻记忆的前瞻成分和回溯成分的年老化影响;实验二检验前瞻成分在前瞻记忆年老化中的作用。结果显示,线索与意向的关联性和线索与背景的区别性作为概念驱动加工和数据驱动加工的重要表现形式可以显著地促进老年人的前瞻记忆水平,前瞻记忆年老化主要存在于前瞻记忆的前瞻成分;前瞻成分较高的注意资源需求导致前瞻记忆的年龄差异主要受任务的认知需求水平所影响,当前瞻记忆是相对自动加工时,年龄差异小;当任务需要较多的控制加工时,年龄差异相对较大。本研究进一步揭示了导致前瞻记忆年龄差异的原因。  相似文献

通过2个实验,对背景任务时间充裕和紧迫两种情况下的具体事件意向、类别事件意向、时间点意向、时间段意向四种前瞻记忆任务对背景任务的干扰效应进行考察。结果表明,在背景任务时间充裕情况下,类别事件意向对背景任务有干扰效应,具体事件意向、时间段意向和时间点意向都没有前瞻干扰效应;在背景任务时间紧迫情况下,时间点意向产生了干扰效应,具体事件意向、类别事件意向、时间段意向均无干扰效应。结果支持前瞻记忆的实现依赖多重加工的观点,时间性前瞻记忆并不一定比事件性前瞻记忆产生更大的干扰。  相似文献
