采用义符启动范式,考察不同加工深度任务中家族大小和类别一致性对义符语义激活的影响。结果发现:在词汇判断中,家族大小影响义符的语义激活,大家族义符的语义不容易激活,小家族义符的语义容易激活。在语义相关判断中,类别一致性影响义符的语义激活,类别一致性高的义符的语义容易激活,并且在错误率上,这一影响受义符的家族大小调节。义符类别一致性影响义符家族效应的作用方向:当类别一致性低时,出现抑制的家族效应;当类别一致性高时,家族效应无影响或表现为促进作用。 相似文献

There is a consensus among philosophers that some “I”-thoughts are immune to error through misidentification. In some recent papers, this property has been formulated in the following deflationist way: an “I”-thought is immune to error through misidentification when it can misrepresent the mental or bodily property self-ascribed but cannot misrepresent the subject (if any) possessing that property. However, it has been put forward that the range of mental and bodily states that are immune in that limited sense cannot include nonconceptual forms of self-representation. In this paper, I claim the opposite. I argue in favor of a theoretical framework inspired by semantic relativism that solves the problem of immune nonconceptual self-representations. In order to do so, I refute an argument against the relativist account which is based on the existence of shared representations. This argument, I contend, rests on a confusion between two conditions to which a relativist may appeal when considering whether a certain mental content is relative to the self: a strong invariance condition and a weak invariance condition. I then argue that even if we acknowledge the existence of shared representations, the weak invariance condition is still satisfied, and consequently the relativist framework can make sense of INSRs. I argue that this weak invariance condition is satisfied by a representational function that self-relativizes certain representations. I then provide an empirical instance of such a function by discussing some of the recent literature on motor representations and the sense of agency. In the last part of the paper, I answer several potential objections. These potential objections lead me to distinguish two fundamental kinds of error relative to the self: error through misidentification and error through misapplication. This distinction allows me to answer a fundamental question raised by the very idea of de facto immunity to error through misidentification. 相似文献

University of Colorado (CU) students were tested for both order and item information in their semantic memory for the “CU Fight Song”. Following an earlier study by Overstreet and Healy [(2011). Item and order information in semantic memory: Students’ retention of the “CU fight song” lyrics. Memory & Cognition, 39, 251–259. doi:10.3758/s13421-010-0018-3], a symmetrical bow-shaped serial position function (with both primacy and recency advantages) was found for reconstructing the order of the nine lines in the song, whereas a function with no primacy advantage was found for recalling a missing word from each line. This difference between order and item information was found even though students filled in missing words without any alternatives provided and missing words came from the beginning, middle, or end of each line. Similar results were found for CU students’ recall of the sequence of Harry Potter book titles and the lyrics of the Scooby Doo theme song. These findings strengthen the claim that the pronounced serial position function in semantic memory occurs largely because of the retention of order, rather than item, information. 相似文献

通过眼动实验考察了语篇背景对不同类型句子语义整合过程的影响。句子类型有3个水平:(1)宾语违反了动词的选择性限制; (2)宾语符合选择性限制, 但是违反了世界知识; (3)无违反。语篇背景有2个水平:(1)中性背景; (2)校正背景。在中性语篇背景下, 句子(1) (2)是不合适的; 而在校正背景下, 三种句子都是合理的。24名大学生被试自然阅读的眼动数据表明, 违反动词选择性限制的目标词上的首次注视时间、回视路径时间和总注视时间, 在中性背景下比在校正背景下长, 注视点个数也更多; 而在非选择性限制违反条件下, 语篇背景的效应只在总注视时间和注视点个数两个指标上显著。这些结果表明, 当句子中的宾语违反了动词的选择性限制时, 语篇背景影响了宾语的早期和晚期加工。而当宾语只违反世界知识时, 语篇背景的作用体现在晚期阶段。语篇背景对当前信息的整合是动态的过程, 并不是只能在固定某个阶段起作用。 相似文献

多媒体学习的认知理论和图文理解整合模型指出, 多媒体学习中图片和文字在早期阶段的加工遵循双通道假设, 在晚期不同表征的信息进行整合完成知识建构。理论上的探讨得到了神经科学实证研究的支持。脑成像研究发现, 图、文加工在早期的前语义阶段存在差异, 但晚期的信息整合阶段共享了同一语义系统。事件相关电位研究也发现在早期图片诱发了独特的N300成分, 而晚期图、文均诱发了N400效应。尽管现有研究已经明确了图、文共享同一语义系统, 但是信息是如何在这一系统中进行整合的还需要进一步的研究。 相似文献

三语者语义通达中的跨语言重复启动效应 总被引:1,自引:0,他引:1
采用跨语言重复启动的任务范式探讨三语者的语义通达机制。被试为在广州学习汉语的印度尼西亚留学生48名。自变量是学习条件(包括学过与未学过), 因变量是单词判断的反应时和正确率。实验1探讨三语者在视觉与听觉呈现的三语词汇语义通达任务中是否会借助于一语对等词, 结果发现一语词汇在两种任务条件下都能够发挥中介作用, 此结果表明了三语者与双语者语义通达机制的一致性; 实验2探讨三语者在视觉与听觉呈现的三语词汇语义通达任务中是否会借助于二语对等词, 结果发现二语词汇只能在视觉呈现任务条件下发挥中介作用, 此结果表明二语词汇在三语语义通达过程中的中介作用具有限制性。本研究结果表明三语者的语义通达机制与双语者既有一致性, 也有其限制性。 相似文献

Sidman (1994) noted that the existence of a member that is common to more than one class may produce either class merger (union) or class intersection. A multiple-selection, matching-to-sample test was developed to examine the conditions under which these outcomes occur. Test trials each required three conditional discriminations involving selection or rejection of comparison stimuli under control of samples representing two categories. Test results obtained from an initial group of typical adults using familiar stimuli (DOG and BIRD, pictures of dogs and birds and relevant printed breed names (e.g., DALMATIAN, RETRIEVER) showed the conditional stimulus control best described as intersection. For example, the word DALMATIAN provided the context for selecting the dalmatian but not the retriever picture. However, these results may have depended on the participants'' verbal history as English speakers. Would conditional-discrimination training with overlapping sets of laboratory-generated stimuli also result in intersection? Naïve typical adults were assigned to one of three different training conditions. Like the participants tested with familiar stimuli, these participants demonstrated highly reliable test outcomes best described as showing class intersection, regardless of training condition. These findings begin to elucidate the necessary and sufficient conditions for establishing complex category-like classes of stimuli. 相似文献

For Chinese compounds, neighbors can share either both orthographic forms and meanings, or orthographic forms only. In this study, central presentation and visual half-field (VF) presentation methods were used in conjunction with ERP measures to investigate how readers solve the sublexical semantic ambiguity of the first constituent character in reading a disyllabic compound. The sublexical ambiguity of the first character was manipulated while the orthographic neighborhood sizes of the first and second character (NS1, NS2) were controlled. Subjective rating of number of meanings corresponding to a character was used as an index of sublexical ambiguity. Results showed that low sublexical ambiguity words elicited a more negative N400 than high sublexical ambiguity words when words were centrally presented. Similar patterns were found when words were presented to the left VF. Interestingly, different patterns were observed for pseudowords. With left VF presentation, high sublexical ambiguity psudowords showed a more negative N400 than low sublexical ambiguity pseudowords. In contrast, with right VF presentation, low sublexical ambiguity pseudowords showed a more negative N400 than high sublexical ambiguity pseudowords. These findings indicate that a level of morphological representation between form and meaning needs to be established and refined in Chinese. In addition, hemispheric asymmetries in the use of word information in ambiguity resolution should be taken into account, even at sublexical level. 相似文献
