The role of orthography in speech production revisited

The language production system of literate adults comprises an orthographic system (used during written language production) and a phonological system (used during spoken language production). Recent psycholinguistic research has investigated possible influences of the orthographic system on the phonological system. This research has produced contrastive results, with some studies showing effects of orthography in the course of normal speech production while others failing to show such effects. In this article, we review the available evidence and consider possible explanations for the discrepancy. We then report two form-preparation experiments which aimed at testing for the effects of orthography in spoken word-production. Our results provide clear evidence that the orthographic properties of the words do not influence their spoken production in picture naming. We discuss this finding in relation to psycholinguistic and neuropsychological investigations of the relationship between written and spoken word-production.     

小学儿童汉字阅读特点初探

该研究运用命名任务、通过两个实验探查了小学儿童汉字阅读的发展特点。实验一发现,小学7岁、8岁、9岁儿童在汉字阅读中受不同汉字结构类型的影响。在笔画数没有显著差异的情况下,独体字的阅读比合体字快,而合体字中上下结构和左右结构类型之间没有差异,而且独体字语音提取的优势从7岁儿童开始就具有了,这种优势稳定地发展下去。实验二在实验一的基础上进一步考察了7岁、9岁、11岁儿童汉字形声字阅读中声旁对整字发音的影响,结果发现,声旁与整字发音一致的形声字阅读快于声旁与整字发音不一致的形声字的阅读,这种汉字阅读中的规则效应从7岁儿童就出现了,而且,稳定地发展下去。     

汉语双字多义词的识别优势效应

采用词汇判断法、命名法考察汉语双字多义词的识别优势效应。结果发现,在词汇判断任务中存在着多义词较单义词的识别优势,但这种识别优势只表现在低频词中。在命名任务中未发现多义词的识别优势。作者根据分布表征模型的观点对双字多义词的识别优势效应做出了可能的解释。     

联想启动与知觉启动的比较研究

采用快速命名方法探讨不同加工水平对联想启动效应的影响。被试分别在深、浅加工条件下学习一系列颜色词,然后完成颜色命名和再认任务,并设立词命名任务,以比较联想启动和知觉启动的异同。结果表明,在颜色命名任务中,深、浅加工条件下均可形成对颜色词的启动效应,但浅加工条件下的再认成绩明显低于深加工,出现了联想启动和再认的分离现象。词命名表现出与颜色命名相似的结果,但它们在有意识回忆方面仍存在一定的差异,提示知觉表征系统单独并不能支持联想启动,联想启动可能是多个记忆系统共同作用的结果。     

图片命名中词汇频率效应的眼动研究

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”。     

Individual differences in banknote processing: the role of altruism

We evaluated whether banknotes processing depended on altruism and attitude towards money. In Experiment 1, context effects were examined when participants named banknotes blocked by category or intermixed with pictures from semantic categories. Attitude towards money was assessed by questionnaires and the degree of altruism was evaluated with the dictator game task. In this task, participants received an amount of money and they had to decide whether to donate all, nothing or part of it. A facilitation effect was found in the banknote naming task and this effect increased as the amount of donations decreased. In Experiment 2, we examined whether less altruistic individuals might focus on the relevant information needed to process banknotes in a monetary Stroop task. Only more altruistic individuals showed Stroop effects. These results are interpreted as due to enhanced control while processing relevant information associated to banknotes in less altruistic individuals.     

Naming and categorization in young children: II. Listener behavior training

Following pretraining with everyday objects, 1- to 4-year-old children received listener training with three pairs of arbitrary stimuli of differing shapes. For each pair, 9 children were trained to select one stimulus in response to the spoken word /zog/ and the other to the spoken word /vek/. Next, in the look-at-sample category match-to-sample test, none categorized the six stimuli correctly when asked to look at the sample before selecting from five comparisons. Seven of these children failed a subsequent test of corresponding speaker behavior (tact test); following tact training, 5 of them passed either a repeat of the look-at-sample category test (2 subjects) or an alternative category test (3 subjects) in which they were required to tact the sample before selecting comparisons. The remaining 2 failed both category tests. Of the 2 who passed the tact test, 1 passed the tact-sample category test; the other failed to complete category testing. Two children were next given a second stimulus set. One passed the look-at-sample category test and the tact test; the other failed both tests but passed the tact-sample category test after tact training. The results show that 1- to 4-year-old children may learn listener behavior without corresponding speaker behavior. The results also show that common listener behavior is not sufficient to establish arbitrary stimulus classes, and they are consistent with the proposition that naming may be necessary for categorization of such stimuli.     

Relations between enabling skills and reading comprehension: a follow-up study of Latvian students from first to second grade

In order to examine the relationships among various phonological skills and reading comprehension, Latvian children were followed from grade 1 to grade 2 and were tested with a battery of phonological, word reading, and reading comprehension tasks. A principal component analysis of the phonological tasks revealed three salient factors: a phonemic awareness factor, a rapid naming factor, and a short-term memory factor. In order to analyze the relationship between various phonological skills and reading comprehension, a structural modeling analysis was performed. Phonemic awareness and rapid naming explained approximately the same amount of unique variance in reading comprehension, but phonemic awareness had most predictive power indirectly via word decoding. Only rapid naming had a significant direct impact on reading comprehension.     

Normative data for the Boston Naming Test in native Dutch-speaking Belgian children and the relation with intelligence

This paper reports the results of a normative study of the 60-item version of the Boston Naming Test (BNT) in a group of 371 native Dutch-speaking Flemish children between the ages of 6 and 12 years. Analysis of test results revealed that BNT performance was significantly affected by age and gender. The gathered norms were shown to be significantly lower than published norms for comparable North-American children. Error analysis disclosed remarkable similarities with data from elderly subjects, with verbal semantic paraphasias and 'don't know' responses occurring most frequently. Finally, BNT scores were shown to correlate strongly with general intelligence as measured with the Raven Progressive Matrices. The relation between both measures can be of help in the diagnosis of identification naming deficits and impaired word-retrieval capacities.     

Essential and Perceptual Attributes of Words in Reflective and On-line Processing

Access to essential and perceptual attributes of word meanings was investigated in a series of tasks. First, perceptual attributes of a number of natural kind concepts were determined by asking participants to generate the most salient features of those concepts; they were asked to assess the importance of both those features and features that fit criteria for essential attributes. Attributes fitting the criteria for essential attributes were found to be judged more important than perceptual attributes in identifying an object and to have more connections to other attributes of the concept. Semantic priming for both types of features was then investigated. Prime-target pairs consisting of the natural kind concept term and the perceptual or essential attribute were presented for lexical decision (Experiments 1a and 1b) or naming (Experiments 2a and 2b). Interstimulus intervals were either 0 or 200 ms. Both types of features were primed at a 200 ms interstimulus interval but only in the lexical decision task.
