Three experiments examined repetition priming for meaningful environmental sounds (e.g., clock ticking, tooth brushing, toilet flushing, etc.) in a sound stem identification paradigm using brief sound cues. Prior encoding of target sounds together with their associated names facilitated subsequent identification of sound stems relative to nonstudied controls. In contrast, prior exposure to names alone in the absence of the environmental sounds did not prime subsequent sound stem identification performance at all (Experiments 1 and 3). Explicit and implicit memory were dissociated such that sound stem cued recall was higher following semantic than nonsemantic encoding, whereas sound priming was insensitive to manipulations of depth encoding (Experiments 2 and 3). These results extend the findings of long-term repetition priming into the auditory nonverbal domain and suggest that priming for environmental sounds is mediated primarily by perceptual processes. 相似文献

Priming refers to a change in the ability to identify or produce an item as a consequence of a specific prior encounter. Priming has been studied extensively in cognitive studies of healthy volunteers, neuropsychological investigations of brain-damaged patients, and, more recently, studies using modern functional neuroimaging techniques such as positron emission tomography and functional magnetic resonance imaging. We review recent neuroimaging studies that have converged upon the conclusion that priming is reliably accompanied by decreased activity in a variety of brain regions. The establishment of this cortical signature of priming is beginning to generate new hypotheses concerning the relation between priming and explicit retrieval, which we illustrate by considering recent experiments on within- and cross-modality priming. 相似文献

记忆心理学领域大量研究证实了内隐记忆和外显记忆的ERP分离,且内隐记忆相比外显记忆在记忆容量、保持时间及稳定性上均有优势。实验记录了15名被试在内隐记忆任务与外显记忆任务中形象图标和抽象图标的行为及ERP数据。结果表明:内隐记忆中,形象图标的行为和300~500ms顶区差异波的启动量均显著高于抽象图标。外显记忆中,形象图标的外显记忆正确率显著高于抽象图标,而反应时无显著差异; 300~500ms额区的差异波,形象图标显著负向于抽象图标,而500~800ms顶区的晚成分差异波两者无显著差异。研究结果表明,形象图标在浅加工下进行无意识记忆具有明显的优势。形象图标与抽象图标在图形化界面语言的使用中一直存在争论,通过实验在行为指标与脑电生理指标上提供了量化证据。 相似文献

In this study, three experiments are presented that investigate the reliability of memory measures. In Experiment 1, the well-known dissociation between explicit (recall, recognition) and implicit memory (picture clarification) as a function of age in a sample of 335 persons aged between 65 and 95 was replicated. Test-retest reliability was significantly lower in implicit than in explicit measures. In Experiment 2, parallel-test reliabilities in a student sample confirmed the finding of Experiment 1. In Experiment 3, the reliability of cued recall and word stem completion was investigated. There were significant priming effects and a dissociation between explicit and implicit memory as a function of levels of processing. However, the reliability of implicit memory measures was again substantially lower than in explicit tests in all test conditions. As a consequence, differential reliabilities of direct and indirect memory tests should be considered as a possible determinant of dissociations between explicit and implicit memory as a function of experimental or quasi-experimental manipulations. 相似文献

Using a picture naming task, we compared the magnitude of repetition priming after one prior study episode (single test priming) versus multiple prior study presentations (multiple test priming). Pictures were repeated either one, two, or three times, and the interval between tests was either several minutes (blocked test) or one week (spaced test). Priming increased with additional prior presentations (beyond one) in the multiple test format. In addition, single test priming decreased within one hour after initial exposure, with little change from one hour to two weeks. Priming was unaffected by a simultaneous recognition task, suggesting that picture naming is an implicit task relatively immune from explicit memory contamination. 相似文献

We gave 12 cognitively normal, elderly adults (mean age = 76.33 years) training and practice on the Colorado Neuropsychology Tests, a computerized battery of explicit and implicit memory tasks. Half the subjects practised on the explicit memory tasks for 1.5 hours a week for 9 weeks with the assistance of a psychologist, while the other half practised on the implicit tasks for the equivalent amount of time. Subjects in both training conditions showed significant improvement within and across training sessions, with those in the implicit memory condition showing the most overall improvement, as indicated by standardized change scores. However, the improved performance on the training tasks did not result in more positive self-assessments of memory capability. In general, subjects displayed favourable attitudes toward the computer technology and were capable of learning to operate the computer software. The results support the practical application of computerized memory training with normal elderly adults. 相似文献

Recently, several studies have addressed the question of whether depression affects priming in implicit memory tasks. The main aim of this experiment was to assess the presence of a bias for negative information in explicit memory (free recall) and implicit memory (word-stem completion) tasks among subclinically depressed subjects compared to nondepressed subjects, using the typical levels of processing manipulation. The results of this study show the existence of a mood-congruent memory bias for both implicit and explicit memory in depressed subjects. The theoretical implications of these findings for implicit and explicit memory biases associated with depressed mood are discussed. 相似文献

Three experiments examined transfer across form (words/pictures) and modality (visual/ auditory) in written word, auditory word, and pictorial implicit memory tests, as well as on a free recall task. Experiment 1 showed no significant transfer across form on any of the three implicit memory tests,and an asymmetric pattern of transfer across modality. In contrast, the free recall results revealed a very different picture. Experiment 2 further investigated the asymmetric modality effects obtained for the implicit memory measures by employing articulatory suppression and picture naming to control the generation of phonological codes. Finally, Experiment 3 examined the effects of overt word naming and covert picture labelling on transfer between study and test form. The results of the experiments are discussed in relation to Tulving and Schacter's (1990) Perceptual Representation Systems framework and Roediger's (1990) Transfer Appropriate Processing theory. 相似文献

内隐和外显记忆测验中的定向遗忘效应 总被引:9,自引:2,他引:7

该研究选取30名被试,采用任务分离实验研究范式探讨不同表面特征图片对内隐记忆和外显记忆的影响。以32张动物图片为实验材料,其中鱼类和鸟类图片各半。两类图片中一半为黑白图片,另一半为彩色图片,所有实验材料用E—Prime软件呈现在电脑上。结果表明:(1)不同表面特征图片的再认成绩(外显记忆)显著好于偏好再认成绩(内隐记忆),即外显记忆成绩好于内隐记忆;(2)在再认测验和偏好判断测验中,再认成绩和偏好再认成绩在图片表面特征的两个水平上存在显著差异;(3)控制组的偏好再认成绩显著好于实验组的偏好再认成绩,即控制组的内隐记忆好于实验组。结论:刺激材料的表面特征既是外显记忆的内容,也是影响外显记忆的重要因素;内隐记忆的作业成绩高度依赖于刺激材料的表面特征,刺激材料的表面特征是影响两种记忆的重要因素。 相似文献
