Phonological spelling   总被引:2,自引:0,他引:2  
A case study is presented of phonological spelling, an acquired spelling disorder in which the primary symptom is the occurrence of phonologically plausible errors (e.g. "flood" → flud). Not all of the patient's spelling errors are as phonologically "perfect" as this example; but it is arguable that the errors primarily derive from a routine which segments a phonological code and assigns orthographic representations to these individual segments. This account of errors in phonological spelling is contrasted with an interpretation of oral reading errors in surface dyslexia. We conclude that errors in the two disorders do not reveal a precise parallel, and that the contrast is partly attributable to the differential role of comprehension in reading and spelling.  相似文献

情绪启动与语义启动发生时孰先孰后、进行中独立平行还是交互作用、效应上孰强孰弱,还存在较大争议.这些争议的本质涉及到人脑中情绪和认知这两大基本系统的关系认识问题.通过行为观察与事件相关脑电位技术结合,在同一个实验中设置情绪启动、语义启动两种情境,并匹配可能影响这两种启动效应的因素,如信息强度、启动刺激和靶刺激的信息关联程度等,然后系统性变化启动刺激呈现的时间、SOA、实验任务等,并逐步加入被试的年龄、性别、学科专业、认知风格、情绪易感性等个体差异变量,可望直接而系统地澄清争议,深层次揭示情绪信息流与语义信息流的加工特点,并进而揭示人脑情绪系统与认知系统功能与机制的发展规律.  相似文献

When a disorder of single word writing is seen in conjunction with preserved oral spelling and intact written grapheme formation ("written spelling agraphia"), the deficit may be presumed to lie somewhere between letter choice and written motor output. Two potential deficits are considered: (1) visual letter codes are not activated properly and (2) the information contained within properly activated visual letter codes fails to reach intact graphic motor patterns. Two patients with written spelling agraphia were each given a series of tests aimed at distinguishing between the two possibilities. Results suggest that the written spelling agraphia seen in these two patients arises from different underlying deficits. The results are discussed in terms of the patients' CT scan lesion sites, which were markedly different.  相似文献

This study examined relations among spelling performance and students' beliefs about spelling, including self-efficacy for spelling ability, outcome expectancy for spelling, and attributions for good spelling across grades 4, 7, and 10. Spelling self-efficacy remained relatively constant across grades. Spelling outcome expectancies for adult life and school declined across grades, as did effort and ability attributions for spelling success, with a disproportional decrease in ability attributions between grades 4 and 7. Self-efficacy was the strongest predictor of spelling performance at all grade levels; attribution for ability entered into the regression for grade 4 students, while outcome expectancies for school and writing were more important in grades 7 and 10. Cluster analyses on the grade 10 sample showed that students with high efficacy as spellers and high outcome expectancy of spelling for writing were the best spellers, with the highest performance reserved for those who attributed good spelling more to effort than ability. The impact of spelling instruction on developing beliefs is discussed.  相似文献

The goal of the current research was to assess whether children can make strategic use of morphological relations among words to spell. French-speaking children in Grade 4 spelled three word types: (a) phonological words that had regular phoneme-grapheme correspondences, (b) morphological words that had silent consonant endings for which a derivative revealed the silent ending, and (c) lexical words that had silent consonant endings for which no familiar derivative revealed the ending. Children were also asked to provide immediate retrospective reports of the strategies used to spell each word. Two experiments (Ns = 46 and 39) were conducted. As expected, children in Grade 4 spelled phonological words more accurately than they did words with silent consonant endings. In addition, children spelled morphological words more accurately than they did lexical words. Reports of using retrieval were associated with accurate performance across word types. Importantly, reports of using morphological strategies to spell morphological words were associated with a similar level of accuracy, as were reports of using retrieval. Even though children reported using a phonological strategy frequently across all word types, this strategy was associated with accurate performance only for spelling phonological words. Experiment 2 replicated the results of Experiment 1 with another set of stimuli and also showed that children's morphological awareness predicted their spelling accuracy for morphological words as well as the reported frequency of morphological strategy use. In sum, the findings revealed that most children showed evidence of adaptive strategy use.  相似文献

实验采用词-词情绪启动范式,在SOA 5个水平上以高频情绪词为靶词,考察情绪启动的反转效应。结果在SOA各个水平上均发现反转效应,即被试对与启动刺激效价一致的靶刺激的反应较慢,而对与启动刺激效价不一致的靶刺激的反应较快。实验结果支持情绪转换模型和快速-准确策略理论。  相似文献

In order to improve the spelling performance of high school students with deficits in written expression, an error self-correction procedure was implemented. The participants were two tenth-grade students and one twelfth-grade student in a program for individuals with learning disabilities. Using an alternating treatments design, the effect of error self-correction was compared with a more traditional method of spelling practice. The intervention and follow-up phases were implemented over a 6-week period with maintenance checks conducted 4 and 8 weeks after the termination of instruction. Results indicated that the error self-correction procedure was superior to the traditional method of review during the intervention and follow-up phases, but some gains were lost during the maintenance phase.  相似文献

Two strategies have been suggested to be important in skilled English spelling: a lexical strategy, which relies on word-specific graphemic information, and a rule strategy, which relies on phoneme-to-grapheme correspondences. Limitations in the usefulness of spelling accuracy as a dependent variable make it difficult to test claims about how the strategies might work together. Two experimental paradigms that measure both spelling accuracy and time are suggested to be useful. Results produced with the paradigms were consistent with the claims that skilled spellers make use of both strategies and that the lexical strategy is more useful than the rule strategy. Working memory may be important in combining products of both strategies. Results were inconsistent with the claim that the rule strategy is invoked only when the lexical strategy fails to produce a complete spelling.  相似文献

采用重复启动范式探讨语义启动效应减少的机制。结果发现,在SOA为短的167ms条件下,重复/相同和重复/相关的启动效应无差异,且重复/相关启动并未导致语义启动效应的减少;而在SOA为长的1200ms条件下,重复/相同和重复/相关的启动效应差异显著,且重复/相关启动导致了语义启动效应的减少,而重复/相同未导致语义启动效应的减少。在抵消了期望和消退的作用后,在SOA为1200ms条件下所得到的重复/相同和重复/相关启动效应的差异,是由于扩散受到了阻碍而导致的。这一结论支持了激活扩散是有一定条件的观点。  相似文献

Environmental context-dependent homophone spelling   总被引:1,自引:0,他引:1  
Two experiments provided evidence of environmental context-dependent memory using a homophone spelling test (e.g., Jacoby & Witherspoon, 1982), an implicit, indirect measure of memory (Richardson-Klavehn & Bjork, 1988). Context reinstatement significantly increased priming in both experiments. The finding of environmental context reinstatement effects with this implicit memory test and others (Garberg & Radtke, 1986; Graf, 1988) indicates that the effect can be found reliably using a test that does not encourage subjects to generate their own context cues from memory.  相似文献

Two studies examined the speed with which good spellers and poor spellers spell easy and difficult words. At both the elementary school (Grades 3 and 4) and undergraduate levels, good spellers spelled words more quickly than poor spellers. This difference appeared even for very easy words that all subjects could spell. Implications for the importance of automaticity in spelling competence are discussed.  相似文献

The present study examined the effects of an error correction strategy on the spelling accuracy of students with emotional and/or learning disabilities. The strategy, which asked students to spell a word, view a correct model, and then correct their errors, was compared to a traditional strategy that asked students to write words three times each while viewing a correct model. Results showed that students learned more words in the error correction condition than in the traditional condition. The error correction treatment was shown to be an effective strategy that reduced the number of repetitive spelling practice trials, and was preferred by students.  相似文献

Growing experimental evidence suggests that temporal events are represented on a mental time line, spatially oriented from left to right. Support for the spatial representation of time comes mostly from studies that have used spatially organized responses. Moreover, many of these studies did not avoid possible confounds attributable to target stimuli that simultaneously convey both spatial and temporal dimensions. Here we show that task-irrelevant, lateralized visuospatial primes affect auditory duration judgments. Responses to short durations were faster when the auditory target was paired with left- than with right-sided primes, whereas responses to long durations were faster when paired with right- than with left-sided primes. Thus, when the representations of physical space and time are concurrently activated, physical space may influence time even when a lateralized, spatially encoded response is not required by the task. The time-space interaction reported here cannot be ascribed to any Spatial-Temporal Association of Response Codes effect. It supports the hypothesis that the representation of time is spatially organized, with short durations represented on the left space and longer ones on the right.  相似文献

Three experiments were conducted using a repetition priming paradigm: Auditory word or environmental sound stimuli were identified by subjects in a pre-test phase, which was followed by a perceptual identification task using either sounds or words in the test phase. Identification of an environmental sound was facilitated by prior presentation of the same sound, but not by prior presentation of a spoken label (Experiments 1 and 2). Similarly, spoken word identification was facilitated by previous presentation of the same word, but not when the word had been used to label an environmental sound (Experiment 1). A degree of abstraction was demonstrated in Experiment 3, which revealed a facilitation effect between similar sounds produced by the same type of source. These results are discussed in terms of the Transfer Appropriate Processing, activation, and systems approaches.  相似文献

Two cases of acquired spelling dyslexia and one case of developmental spelling dyslexia are described along with accounts of their performance on various psycholinguistic tasks. It is argued that there is some evidence that spelling dyslexia may exist in developmental form but that parallels are difficult to draw because of the very different histories of child and adult cases. It is also suggested that features of surface dyslexia exist in at least a proportion of spelling dyslexic cases and that this may be influenced by level of premorbid reading skill.  相似文献

The authors investigated the perceived relationship between spelling errors and cognitive abilities in a series of 3 experiments. Specifically, they examined whether college students' ratings of an author's intellectual ability, logical ability, and writing ability were affected by the presence of spelling errors. In the 1st experiment, the presence of 4 spelling errors in a short essay did not significantly affect the ratings. The spelling ability of college students, as measured by a standard oral dictation spelling test, was moderately conelated with a brief test of intelligence. In a 2nd experiment, college students rated the author of a short essay as having lower ability when there was a large number of spelling errors. The effect was more pronounced on the ratings of writing ability than it was on the ratings of logical ability or intellectual ability. This finding was replicated in a 3rd experiment, in which the essay contained misspellings actually made by writers. The results suggest that spelling errors can affect how people perceive writers, particularly when there are many spelling errors. College students appear to attribute spelling errors more to writing ability than they do to general cognitive abilities such as intelligence and logical ability.  相似文献
