以中国汉字为材料,考察不同系列项目呈现时间范式中的系列位置效应,并验证Neath提出的区辨理论公式对中文材料的适用性。结果表明,在非常短暂的系列项目呈现时间,并且项目之间的时间间隔按不同中数比率变化的实验条件中.均存在明显的系列位置效应;但是Neath提出的区辨理论的公式,不能预测本实验结果,从另一个方面说明汉字不同于拼音文字的特点。 相似文献

在Healy等人(2008)的实验范式基础上,以中文姓名作为实验材料,探究位置特异性和项目呈现方式对即时情景记忆的影响。两个实验都要求被试对所呈现的20个姓名中的12个进行顺序重构。重构的12个位置分别为1-12、5-16、9-20三个水平,这三组位置同时包括绝对位置9-12。实验1采取视觉呈现,比较三个任务类型上重构正确率的差异。实验1的结果支持Healy的编码特异性理论,但是末尾呈现的项目仅有较小的重构优势。实验2采取听觉呈现,结果发现,在系列位置5-16上出现了较明显的近因效应,而在位置9-20上并无明显的近因效应。这表明位置特异性理论对顺序重构的影响主要表现为绝对位置的特异性而并非相对位置的特异性,系列位置效应出现在记忆的编码过程而不是提取过程。 相似文献

自由回忆和线索回忆测验中的系列位置效应 总被引:2,自引:1,他引:2
本文以96个中国汉字为材料,使用自由回忆和线索回忆测验方法,对20名被试进行6组分测验和最后所有汉字的总测验。发现自由回忆分测验中存在明显的系列位置效应,总测验出现负近因现象;线索回忆分测验也表现出明显的系列位置效应,但最后的总测验没有出现负近因现象。上述结果验证了Bjork和Whitten(1974)提出的顺序或情景理论。 相似文献

教育心理学领域的不流畅效应认为,学习难读材料要比学习易读材料的效果更好。已有研究主要通过操纵学习材料中的文本、画面或声音属性考察知觉流畅性在学习过程中的作用,并发现不流畅材料可能有助于缓解过度自信现象,但不一定能提高学习效果,不流畅效应的稳健性受到质疑。合理难度理论与不流畅理论均认为,知觉不流畅所引发的额外认知负荷促进了学习;相反,认知负荷理论认为这种额外认知负荷会阻碍学习。对现有研究进行元分析,结果表明,知觉不流畅既降低了学习判断的自信心(d=-0.54),也不利于提高学习效果(d=-0.36),一定程度上支持认知负荷理论。未来研究需关注知觉流畅性本身的操纵、界限及系统性评定,并探讨不流畅效应的边界条件等。 相似文献

Micro-position effects in visual short term memory 总被引:1,自引:0,他引:1
Short-term memory for visually presented eight-digit numbers was tested in a forced recall, read-and-dial task. The digits were presented non-grouped or grouped in 2+2+2+2 or 2+3+3 digit formats. Spatial grouping enhanced memory performance and produced local discontinuities in the serial position curves related to grouping format. These micro-position effects are explained in terms of the relative spatial distinctiveness of individual digits. 相似文献

ABSTRACTEvidence for false recognition within seconds of encoding suggests that semantic-associative influences are not restricted to long-term memory, consistent with unitary memory accounts but contrary to dual store models. The present study sought further relevant evidence using a modified free recall converging associates task where participants studied 12-item lists composed of 3 semantically distinct quartets (sublists) related to a separate, non-presented theme word (i.e., words 1–4/theme1, 5–8/theme2, and 9–12/theme3). This list construction permits assessment of false recall errors from each sublist, and, particularly, the primacy and recency sublists that have been linked to long- and short-term memory stores. Experiment 1 tested immediate free recall for items. Associative false memories were evident from all sublists, however, significantly less so from the recent sublist, which also showed the highest levels of veridical memory. By inserting a brief (3?s) distractor prior to recall, Experiment 2 selectively reduced veridical memory and increased false memory for the recent sublist while leaving the primacy sublist unaffected. These recall results converge with prior evidence indicating the immediacy of false recognition, and can be understood within a unitary framework where the differential availability of verbatim features and gist-based cues affect memory for primacy and recency sublists. 相似文献

We examine serial order memory for sequences of tactile stimuli and investigate whether established characteristics of order memory, namely serial position effects, error distributions, and Hebb repetition learning, are observed with tactile memory. Visually obscured participants received six tactile stimulations: one to each of six fingers. At test, participants lifted the six fingers in the order of stimulation. For every third trial participants received the same order of stimulation (i.e. the Hebb sequence). Serial recall accuracy produced the canonical bowed serial position function found for immediate serial recall. In addition, recall for the Hebb sequence improved relative to the filler sequences, providing the first demonstration of the Hebb repetition effect with tactile stimuli. Analysis of errors revealed close similarities to that reported with verbal and visual stimuli. This experiment further generalises established features of order memory to tactile memory, supporting the utilisation of an analogous order memory mechanism across stimuli. 相似文献

The present paper examines the effect of within-sequence item repetitions in tactile order memory. Employing an immediate serial recall procedure, participants reconstructed a six-item sequence tapped upon their fingers by moving those fingers in the order of original stimulation. In Experiment 1a, within-sequence repetition of an item separated by two-intervening items resulted in a significant reduction in recall accuracy for that repeated item (i.e., the Ranschburg effect). In Experiment 1b, within-sequence repetition of an adjacent item resulted in significant recall facilitation for that repeated item. These effects mirror those reported for verbal stimuli (e.g., Henson, 1998a. Item repetition in short-term memory: Ranschburg repeated. Journal of Experimental Psychology: Learning, Memory, and Cognition, 24(5), 1162–1181. doi:doi.org/10.1037/0278-7393.24.5.1162). These data are the first to demonstrate the Ranschburg effect with non-verbal stimuli and suggest further cross-modal similarities in order memory. 相似文献

The focus of the present article was to analyze processes that determine the enactment and age effect in a multi-trial free recall paradigm by looking at the serial position effects. In an experimental study (see Schatz et al 2010), the performance-enhancing effect of enactive encoding and repeated learning was tested with older and younger participants. As expected, there was a steady improvement of memory performance as a function of repeated learning regardless of age. In addition, enactive encoding led to a better memory performance than verbal encoding in both age groups. Furthermore, younger adults outperformed the elderly regardless of type of encoding. Analyses in the present article show that encoding by enacting seems to profit especially from remembering the last items of a presented list. Regarding age differences, younger outperformed older participants in nearly all item positions. The performance enhancement after task repetition is due to a higher amount of recalled items in the middle positions in a subject performed task (SPT) and a verbal task (VT) as well as the last positions of a learned list in VT. 相似文献

Serial position effects in visual short-term memory for words and abstract spatial patterns 总被引:1,自引:0,他引:1
Two experiments tested the effects of list postion, and retention-interval in recognition for two distinct stimulus categories in young adults. Stimulus categories were spatial abstract patterns and words presented on a computer screen. At short delay intervals recency effects predominates and at longer delay intervals a primacy effect predominates in both experiments, indicating similar basic memory processes producing the serial position functions for the two different categories of visual stimuli, but as length of retention-interval increases, memory for first list items improves for words and remains constant for abstract patterns. Recency functions are similar for both stimulus categories tested. 相似文献
