蒙语词汇识别中语音自动激活的ERP研究

采用快速掩蔽启动范式、Go/No-go范式和事件相关电位（ERP）技术,探讨蒙语词汇识别过程中语音自动激活的时程及对语义通达的作用。实验中要求被试执行一个额外的语义分类任务,对关键刺激不做明显的行为反应。结果发现,SOA为67ms时,语音启动在头皮的额区诱发了明显的P150和N400成分;SOA为167ms时,语音启动在头皮的额区和中央区诱发了明显的P200成分,在整个大脑皮层诱发了明显的N400成分。结果表明,语音在蒙语词汇识别的早期自动激活并促进语义的通达。     

汉字形声字声旁的语义加工(英文)

作为汉字书写系统和意义表达基本单位的汉字可分为独体字(占5％)和合体字(占95％)两大类。绝大多数合体字由两部分组成：义旁(通常在左边)和声旁(通常在右边)。声旁能够为这些合体字提供语音信息。根据声旁的读音与整字的读音是否一致,可把合体字分为规则字和不规则字。本研究的目的在于考察合体字声旁的亚词汇加工是否仅仅是一个纯粹的语音事件,只涉及声旁的语音加工,还是同时也是一个语义事件,涉及到声旁语义信息的激活。要求被试对屏幕上先后呈现的合体字(如“冯”)和与其声旁语义相关的字(“牛”)作语义相关判断。整字之间并无语义关系,被试正确的反应应是“否”。实验结果表明,相对于完全无关的控制组(如“冯——后”)来说,被试对声旁相关组的反应明显减慢,出现了抑制效应。这种效应基本不受整字的读音规则性和呈现顺序的影响。这些实验结果表达了合体字加工中的分解和平行激活过程。在整字加工的同时,声旁在心理词典中的语音和语义表征得到了激活。汉字声旁的亚词汇加工既是个语音事件,也是个语义事件,与词汇水平的加工没有本质的区别。     

汉语语音的语义作用研究

本研究采用语音中介语义启动的实验任务,考察了语音表征在语义激活中的作用。实验一发现,在频率较高的词的加工中没有发现语音中介语义启动效应;在频率较低的词的加工中得到了语音中介语义启动效应,但是这种中介启动效应与直接的语义启动效应有显著差异。实验二进一步考察了当声旁读音与整字语音一致时,整字语音在语义通达中的作用,结果发现:不论是高频字还是低频字,语音中介启动对目标词的加工都有促进效应,并且高频条件下,语音中介启动效应与直接的语义启动效应没有显著差异。     

再探汉字加工中语音、语义激活的相对时间进程

在Zhou和Marslen-Wilson（2000）基础之上,进一步探讨汉字加工中语音和语义信息激活的相对时间进程及其对汉字加工理论的含义。采用启动范式,用同一目标字与语义相关启动字、同音启动字以及无关控制启动字配对,变化同音启动字读音与其声旁的规则性,变化启动字与目标字呈现之间的时间间隔（SOA,57ms或200ms）,使用两种实验任务（真假字判断和命名）,考察语义、语音效应发生的时间先后与效应量的大小。真假字判断实验发现,不管SOA如何,语义启动效应都非常显著,而同音启动效应则随SOA的增长而逐渐加大,从不显著到显著;同音启动字读音规则性对启动效应没有明显影响。命名实验发现,语义启动、同音启动效应同时存在于长、短SOA条件中。长SOA时,两者在数值上没有显著差异;短SOA时,同音不规则字产生的启动效应等同于语义启动效应,而同音规则字产生的启动效应则大于语义启动效应。结合其它实验发现,这些结果说明,在熟练的汉字加工中,语音信息的激活并不比语义信息早,语音激活也不是语义激活的先决条件;但汉字各种信息激活的相对激活量和时间进程会随任务性质和材料性质而在一定范围内有所改变。     

语音在汉字语义通达中作用的研究述评

语音在汉字语义通达中的作用是二十多年来心理语言学研究的热点之一。直通假设和形音交互假设是学者们主张的理论观点,它们在语音和语义的相互关系上存在分歧,并分别有各自的实验证据。从比较语音语义激活时间进程、同音字效应、神经心理学与脑成像、语音作用的发展转换这四个方面对过去的研究进行回顾,指出了实验范式和实验材料中存在的问题,并提出结合汉字特点进行研究的思路。     

汉字识别中形音义激活时间进程的研究(Ⅰ)

分别采用基于语义的和基于语音的启动范畴判断作业,在不同的SOA条件下,考察高频汉字识别中形音义信息激活的相对时间进程。两个实验的结果表明,高频汉字形音义激活的时序为字形—字义—字音的顺序。这一结果揭示,高频汉字字义的提取更符合直通理论的预期。高频汉字的语音是自动激活的,但语音的激活可能发生在字义通达之后。

声符和义符在形声字语音、语义提取中的作用

采用眼动技术记录汉语阅读者在形声字的语音、语义提取中对声符和义符的注意规律, 考察形声字部件的位置、功能和正字法意识对汉字认知的影响。结果表明：(1)在汉字的视觉加工中, 阅读者对部件空间位置的注意加工优势受到声旁位置的调节。对左形右声结构的汉字, 被试更多地注意字的右边, 对右形左声结构的汉字, 被试更多地注意字的左边; (2)在汉语阅读者的正字法规则中, 存在着“左侧释义、右侧释音”的部件的位置-功能联结。(3)在通达形声字的语音、语义的过程中, 与义符相比, 声符具有注意资源的优势, 这种优势在语音提取任务中更加明显：声符无需依赖义符的信息便可以相对独立地激活整字的语音, 但声符需要义符的配合才能够提取整字的语义。     

The role of phonological activation in the visual semantic retrieval of Chinese characters

The Stroop paradigm was used to examine the role of phonological activation in semantic access and its development in reading Chinese characters. Subjects (age 7-23 years) of different reading ability were asked to name the display color of Chinese characters. The characters were displayed in four different colors: red, yellow, blue and green. There were five types of relationships between a character and its display color: semantically congruent, phonologically congruent, semantically incongruent, phonologically incongruent and neutral. In addition to the classical Stroop effects, interference and facilitation effects from the homophones of color characters were also observed. The younger children and those with lower reading ability exhibited stronger Stroop effects. These findings suggest that phonological codes are activated automatically in Chinese character recognition. Furthermore, there is more phonological activation in the semantic retrieval of children in lower grades and those with lower reading ability.     

Large number discrimination in 6-month-old infants

Two experiments with the Stroop paradigm were conducted to investigate the role of phonological codes in access to the meaning of Chinese characters. Subjects named the ink color of viewed characters or color patches. Key items were color characters, their homophones with the same tone, homophones with different tones, and semantic associates. Apart from finding the usual Stroop interference effect, homophones produced significant interference in the incongruent condition, provided that they had the same tone as the color characters. The interference effect from homophones, however, was significantly smaller than that from color characters. Semantic associates generated an interference effect in the incongruent condition, an effect of the same magnitude as the effect from the same-tone homophones. Finally, in the congruent conditions, all the key items yielded facilitations compared to neutral controls, though the facilitation from color characters was larger than the facilitations from other types of characters. These findings suggest that phonological codes in Chinese are activated obligatorily and provide early sources of constraint in access to meaning.     

Judging pictorial and linguistic aspects of space

A test is made of the notion that Stroop-like interference and facilitation effects arise from two different sources, one pictorial and the other linguistic. It was hypothesized that when irrelevant information is pictorial, it interferes with a pictorial code used in the processing of the relevant information; when it is linguistic, it interferes with a linguistic code. The experiment required subjects to respond to (1) the meaning of a spatial word, t2) its absolute position, or (3) its relative position, while attempting to ignore the two irrelevant dimensions of the display. It was found that word meaning and absolute position information affected the speed of relative position judgments in an additive manner. No other Stroop-like effects were found. The results supported the hypothesis under test. It was concluded that the existence of different kinds of Stroop effect must be accommodated by current models of the phenomenon.     

汉字、拼音、英文Stroop干扰效应的比较研究

本研究通过比较汉字、拼音和英文的Stroop干扰效应,考察文字系统的差异能否影响Stroop干扰效应。结果表明汉字、拼音、英文在Stroop任务中的干扰效应依次降低。组块之间的比较表明随着刺激的重复呈现,汉字、拼音、英文的Stroop干扰效应都逐渐变小且趋于相同。对Stroop效应更加合理的理论解释是整合了文字加工过程的平行分布加工模型。     

概化理论预算限制下最佳样本量估计

概化理论广泛应用于各种心理测评实践中。当有预算限制时,概化理论需要考虑如何设计一个测量可靠性相对较高且可行性也相对较强的测量程序,这就要求通过某些途径估计最佳样本量。拉格朗日乘法是概化理论预算限制下最佳样本量估计较为成熟的方法。探讨了概化理论预算限制下最佳样本量估计的一些影响因素,如受总预算舍入的影响等,也提出了一些后续改善的建议,如推导出拉格朗日乘法的统一公式等     

Effect of conflicting cues on information processing: the 'Stroop effect' vs. the 'Simon effect'

This study examined the relationship between two sources of interference in human information processing: the Stroop effect and the Simon effect. Forty subjects pressed a left- or right-hand key in response to a Stroop color word located on the left or right side of a screen. For one group, ink color was the relevant cue and, for another group, word meaning was the relevant cue. Independent variables were: congruence, i.e., agreement or lack thereof between the ink color and meaning of the Stroop word; spatial correspondence, i.e., agreement or lack thereof between the location of the Stroop word and the location of the key used to make the response; and stimulus duration, i.e., 400 or 100 ms. Each of these variables had a significant effect on RT, and there were no significant interactions. According to Sternberg's additive-factor logic, these findings suggest that the Stroop effect (congruence) and the Simon effect (spatial correspondence) involve separate stages of processing. If one assumes that manipulation of stimulus duration effects the encoding stage, then results also suggest that neither the Stroop effect nor the Simon effect involves the stimulus encoding stage.     

The Effects of Procedural Variations on Lateralized Stroop Effects

Several issues in the classic Stroop effect remain open, including (i) the stage of processing which gives rise to the effect, (ii) the effect of some procedural manipulations, (iii) the effect of hemispheric specialization and of interhemispheric interactions, and (iv) the existence of individual differences. In this paper, we investigate these issues using a series of experiments with central, lateral, and bilateral presentations of the Stroop stimuli. A total of 146 right-handed subjects took part in a multiexperiment study with relatively equal numbers of the two sexes participating in each experiment. We found that manual responses diluted but did not abolish the Stroop interference relative to vocal responses, arguing for a late processing stage account of the effect. However, separating the color patch from the color word either unilaterally or bilaterally did not significantly change the magnitude of the Stroop interference, arguing against a cost of interhemispheric transfer in the Stroop effect in normal subjects. We did, however, find evidence for hemispheric specialization in Stroop interference, greater in the left hemisphere than in the right hemisphere. Color words in the RVF produced the greatest Stroop effects regardless of the location of the color patch. In most cases, this laterality effect interacted with the sex of the subject, such that only males and a subgroup of females (i.e., those tested during a low estrogen phase in the menstrual cycle) showed evidence for greater Stroop effects when a color word projected to the left hemisphere than when it projected to the right hemisphere, regardless of the placement of the color patch.     

青少年Stroop效应和反转Stroop效应的脑事件相关电位研究

研究了初中生、高中生和大学生在完成Stroop任务时的脑事件相关电位特征。以中文Stroop色字为材料,对颜色和字义任务中一致刺激和不一致刺激的脑电叠加平均,并相减(不一致刺激减一致刺激)得到差异波,比较各组被试的波形。结果发现:在顶区,初中生的P3比高中生和大学生更为正走向;大学生、高中生和初中生的头皮分布呈现出不同的特征;Nd4与Stroop效应和反转的Stroop效应有关,可能反映了对无关信息的抑制,而Pd6则反映了对语义信息的再加工。     

Verbal coding and the elimination of Stroop interference in a matching task

Translational models of the Stroop effect (Virzi & Egeth, 1985) predict that Stroop interference can be eliminated if subjects can be induced to process target colors using a coding system separate from the coding system used to process distractors. This hypothesis was tested in two experiments. In the first experiment, we attempted to eliminate the need for subjects to translate target colors to verbal codes when responding to Stroop stimuli. Before responding to verbal incongruent color word distractors, subjects practiced matching colors to irregular shapes. It was expected that subjects would use nonverbal codes to mediate responding in this task. After practice, subjects continued the matching task in the presence of incongruent color words. Stroop interference persisted, contrary to predictions. Because subjects reported adopting verbal strategies to perform the matching task, Experiment 2 was designed to control the verbal coding strategies that subjects employed. Before responding to Stroop distractor stimuli, subjects in the nonsense name group practiced using nonsense names to mediate the matching of shapes to colors; subjects in the actual name group used actual color names to mediate performance in the matching task. When incongruent color word distractors were introduced, Stroop interference was eliminated for subjects in the nonsense name group, but persisted for subjects in the actual name group. The results are interpreted as consistent with an outcome conflict (Navon & Miller, 1987) or a modified translational model of the Stroop effect.     

A reverse Stroop effect without translation or reading difficulty

It is well known that irrelevant color words affect the time needed to identify the color they are displayed in (the Stroop effect). One major view is that a reverse Stroop effect (RSE)—in which the irrelevant color affects the time needed to identify the word—does not occur unless a translation is needed between domain-specific memory codes. In the present article, we report an experiment in which the reverse Stroop effect was investigated by having subjects identify a colored word at fixation by pointing to a location on the screen containing that word. Although the response was untranslated, an RSE was observed. An account is provided in which the strength of association between a stimulus and a specific response plays a central role.
