The advantage of naming pseudohomophones over non-pseudohomophones has been interpreted as reflecting the contribution of whole-word lexical representations in phonological coding. A whole-word interpretation was further supported by Taft and Russell (1992), who reported a pseudohomophone frequency effect such that pseudohomophones were named faster if they corresponded to high- than to low-frequency base-words (e.g. poast vs. hoast ). Experiment 1 replicated this pseudohomophone frequency effect using the Taft and Russell items. Further analyses showed, however, that the pseudohomophones in Taft and Russell's high-frequency group were more orthographically similar to words than the pseudohomophones in the low-frequency group. These differences in orthography may have been the cause of the 'frequency' effects. In Experiment 2, a new set of high- and low-frequency pseudohomophones was constructed that were matched on orthographic factors (i.e. SPBF and N). With these items, a standard pseudohomophone advantage was found such that pseudohomophones were named faster and more accurately than non-pseudohomophones. However, in contrast to Taft and Russell's results, pseudohomophone naming was not related to base-word frequency. We conclude that the pseudohomophone advantage occurs at a postlexical stage in non-word naming.  相似文献

There has been an increasing volume of evidence supporting the role of the syllable in word processing tasks. Recently it has also been shown that orthographic redundancy, related to the pattern of bigram frequencies, could not explain the syllable number effect on lexical decision times. This was demonstrated on a large sample of words taken from the British Lexicon Project. In this study we extend this research by examining both lexical decision and word naming times taken from the English Lexicon Project . There was a syllable number effect for both tasks in the expected direction, and this effect was independent of the presence of a bigram trough. The research also examined the role of other bigram related variables and the number of morphemes on lexical decision and word naming times. The number of morphemes had a significant effect on both word processing tasks, with words with more morphemes producing faster reaction times and also fewer errors. This pattern was reversed for nonword lexical decision times. The results are discussed in the light of recent developments in models of reading.  相似文献

在延时命名范式的基础上,通过控制熟悉性并运用连续图片命名的眼动记录技术,考察图片的注视时间,将词汇提取的过程单独地呈现出来。实验结果表明,在控制熟悉性及延时命名的条件下,图片名称的频率仍影响着图片的注视时间,表现出频率效应,但对出声输出的快慢没有影响,从而进一步证实了图片命名频率效应的“词汇通达假设”。  相似文献

Abstract

Recent theories of recognition memory have identified two bases on which recognition-memory judgments may be made: recollection, which involves retrieval of contextual information from an earlier episode of stimulus presentation; and familiarity, which is distinguished by a general sense of familiarity in the absence of recollection. Four experiments were conducted to test whether the word frequency effect (WFE) in recognition memory (superior performance with low- in comparison with high-frequency targets) results from recollection-based processes, familiarity-based processes, or both. In two of the experiments, superior memory for aspects of the study context was found for low-frequency in comparison with high-frequency words, suggesting frequency-related differences in recollection. The other two experiments used Jacoby's (1991) inclusion/exclusion paradigm to provide estimates of the contribution of recollection and familiarity to recognition. In both experiments the data suggested that the WFE is primarily a recollection-based phenomenon. These findings suggest that the recognition memory WFE for old items results primarily from the effects of word frequency on recollection. The implications of these findings for theories of recognition memory are discussed.  相似文献

对于同音词家族较大的词汇(例如汉语单音节词), 听觉通道的词汇通达和词汇表征的激活会受同音词汇歧义怎样的影响, 仍不很清楚。本研究采用了两个听觉通道的实验。实验一的听写任务发现在孤立音节的同音字选择上存在歧义的同时还存在同音字族内的高频偏向, 并非随机选择; 实验二的音-字同音判断任务对比同音与不同音条件得到同音促进量, 揭示了孤立音节在激活语音表征时还会引起同音高频字表征的自动激活, 而同音低频字则受到抑制。结果说明存在同音字族内的听觉通道词频效应, 同音的高、中、低频字的表征激活具有不同等性, 导致不穷尽通达, 且同音的最高频字得到更多通达机会。这些发现难以被现有的词汇通达和同音词表征激活模型解释, 文章提出一个能够解释这些听觉通道发现的模型。  相似文献

The issue addressed in this study is whether there are differential effects of number of letters on word and nonword naming latency. Experiment 1 examined the effect of number of letters on latency for naming high-frequency words, low-frequency words, and nonwords. Number of letters affected latency for low-frequency words and nonwords but did not affect latency for high-frequency words. Number of letters was also negatively correlated with number of orthographic neighbours, number of friends, and average grapheme frequency. Number of letters continued to affect nonword naming latency, but not low-frequency word naming latency, after the effects of orthographic neighbourhood size, number of friends, and average grapheme frequency had been accounted for. Experiment 2 found that number of letters had no effect on the latency of delayed naming of the same words and nonwords. It is concluded that the effect of number of letters on nonword naming reflects a sequential, non-lexical reading mechanism.  相似文献

词频是否影响列表法定向遗忘一直是记忆心理学研究的热点.本研究引入词频(高频词、低频词)变量,通过操作指示符(记住、遗忘)来考察内隐记忆测验中列表法定向遗忘效应,结果显示:(1)在低频词语中,内隐记忆测验出现了显著的列表法定向遗忘效应;(2)而在高频词语上,内隐记忆测验中却未出现列表法定向遗忘效应;(2)列表法定向遗忘影响内隐记忆测验的机制应该是提取抑制.  相似文献

The present study investigated the effects of prior grammatical gender information (masculine, feminine, and neuter) provided by a minimal sentence context on both picture- and word-naming latencies. Named targets were nouns or pictures of concepts featuring unambiguous grammatical gender. Simple sentence fragments were presented auditorily prior to each picture or word target; the relation between these sentence primes and the word or picture target was either gender-congruent, gender-incongruent, or gender-neutral. Relative to the gender-neutral baseline, reliable facilitation and inhibition effects were both observed in the picture-naming task. By contrast, only inhibition effects were observed in the word-naming task. The results suggest that the processes of picture and word naming differ qualitatively when gender information is precued. The findings are discussed with respect to the distinction between postlexical and intralexical loci of the effects of gender context on word recognition and production.  相似文献

词汇习得年龄和频率对词汇识别的影响   总被引:6,自引:1,他引:6  
三个实验考察词汇习得年龄和频率在词汇识别中的作用。实验结果表明:词汇习得年龄是影响汉语双字词词汇识别的重要因素,表现为早期习得的词汇比晚期习得的词汇更具有加工的优势。词汇习得年龄和频率独立地影响汉语双字词的识别过程.它们之间的效应是一种相加的关系。本研究还对词汇习得年龄效应的机制进行了讨论。  相似文献

In models of word retrieval, it is common to differentiate lexical-semantic (word meaning) and lexical-phonological (word form) levels. There has been considerable interest in the relationship between these two levels. The so-called discrete two-stage model claims that phonological activation follows selection at the lexical-semantic level and is limited only to the selected item. In contrast, nondiscrete (interactive and cascade) models assume that all activated lexical-semantic candidates are also phonologically activated to some extent. We addressed this issue by studying an anomic patient who suffered from a partial functional disconnection between lexical-semantic and lexical-phonological levels. A multitarget repeated naming task with phonological training was employed. Systematic manipulation of semantic and phonological relatedness between the to-be-named items indicated that our patient's word error patterns were sensitive to both types of lexical relatedness. A delayed repetition task employing the same items failed to show similar effects, suggesting that they were specific to naming. The discrete two-stage model is unable to explain the observed effects of semantic and phonological relatedness. However, they are consistent with assumptions of nondiscrete models of lexical retrieval. In addition to the theoretical implications of this study, the observed effects of lexical context on word retrieval have implications for treatment of anomia.  相似文献

通过个案跟踪和控制实验探讨了词汇飞跃的本质。研究结果表明命名洞察力具有现实性,且词汇飞跃与命名洞察力的出现紧密相关,这在一定程度上解释了儿童词汇量快速增长的原因。命名洞察力的获得促进了词汇的快速增长,标志着儿童建立起词汇与指称之间的匹配关系。词汇飞跃之后,儿童很快建立起词语间的符号关系,并最终促进了儿童语法的发展。基于此实证结果,本研究还建构了诠释词汇飞跃本质的理论模型。  相似文献

The effects of the frequency of a surname in the population and of the distinctiveness of a face on the latency to name famous faces were explored. Distinctive faces were named more quickly than were typical faces. Celebrities with low-frequency surnames were named faster than celebrities with high-frequency surnames, but only if their faces were distinctive. Subsequent experiments showed that the effect of surname frequency could not be attributed to differences in the articulatory onsets of the surnames and was not present in a task that did not require a naming response. Experiments in which surnames were taught to previously unfamiliar faces showed that familiar surnames (e.g. the surnames of celebrities) were produced more rapidly than were unfamiliar surnames. If familiar surnames were taught, no effect of surname frequency was observed. It is concluded that lexical access to peoples' names is frequency sensitive—surnames shared by few individuals are accessed faster than are high-frequency surnames. However, when learning names to unfamiliar faces, familiar surnames (i.e. the surnames of people already known to the subject) are learned and accessed more quickly than unfamiliar surnames.  相似文献

本文采用字表方式,从高低词频和新旧效应角度,探讨内隐和外显测验中定向遗忘效应的存在性及其机制问题。结果发现:(1)低频词在两种测验中都存在定向遗忘效应,而高频词仅存在于外显测验中。(2)两种测验中都存在指示记住的新旧效应,而外显测验中不存在指示忘记的新旧效应。由此推断,测验间在没有"意识和无意识"相互污染的理想情况下,只有外显测验可获得定向遗忘效应;定向遗忘的机制可能是选择性编码机制。  相似文献

产生效应是指朗读单词的记忆成绩要好于默读单词的。目前存在特异观和强度观两种理论解释,特异观强调朗读的相对特殊性,强度观强调朗读单词的编码强度高于默读单词的。为了检验两种理论,本研究采用“学习-再认”的实验范式,将阅读方式分别设置为被试内和被试间变量,通过两项实验考察阅读方式和学习次数对中文词汇的产生效应的影响。实验1采用被试内设计考察阅读方式和学习次数对产生效应的影响。结果发现阅读方式和学习次数的主效应显著,二者的交互作用不显著。实验2将阅读方式设置为被试间变量,采用混合设计考察阅读方式和学习次数对产生效应的影响。结果发现学习次数的主效应显著,阅读方式的主效应和二者的交互作用不显著。结果表明产生效应未随着项目编码强度的增强而增强,支持特异观。  相似文献

通过词汇判断任务,探讨语素频率对中级印尼汉语学习者复合词识别的影响。研究结果发现,语素频率影响中级印尼汉语学习者复合词的识别。同时,语素频率对词汇识别的影响受到语素位置的调节。当语素为复合词的首语素时,语素频率高,词汇判断的正确率高;语素频率低,词汇判断的正确率低。当语素为复合词的尾语素时,语素频率对词汇判断正确率的影响受到首语素频率的限制。只有当首语素的频率高时,尾语素的频率才会影响词汇判断的正确率。当首语素的频率低时,尾语素的频率不影响词汇判断的正确率。研究结果支持中级印尼汉语学习者在复合词的表征中产生了语素表征,而且首语素的频率在复合词识别中发挥更重要的作用。  相似文献

用字判断任务考察单字词的词频和累计频率(字频)的作用。实验一发现单字词有词频效应,词频和词素频率没有交互作用。实验二同时发现了累计频率和词频的作用。结果表明单字词的词素频率被部分累计,其词频和累计频率共同影响其加工,支持了汉语词汇加工的双频作用特点,也为匹配汉字频率提供了新的证据。  相似文献

Prior research has shown that people can learn many nouns (i.e., word–object mappings) from a short series of ambiguous situations containing multiple words and objects. For successful cross‐situational learning, people must approximately track which words and referents co‐occur most frequently. This study investigates the effects of allowing some word‐referent pairs to appear more frequently than others, as is true in real‐world learning environments. Surprisingly, high‐frequency pairs are not always learned better, but can also boost learning of other pairs. Using a recent associative model (Kachergis, Yu, & Shiffrin, 2012), we explain how mixing pairs of different frequencies can bootstrap late learning of the low‐frequency pairs based on early learning of higher frequency pairs. We also manipulate contextual diversity, the number of pairs a given pair appears with across training, since it is naturalistically confounded with frequency. The associative model has competing familiarity and uncertainty biases, and their interaction is able to capture the individual and combined effects of frequency and contextual diversity on human learning. Two other recent word‐learning models do not account for the behavioral findings.  相似文献
