汉字输入法对汉字字词加工的影响研究   总被引:1,自引:0,他引:1  
钱华  冯成志 《心理科学》2004,27(6):1368-1370
用形似判断和同音判断作业就输入法对汉字字词加工的影响作了考察。结果表明,汉字输入法及输入速度对小学生语文学习存在明显的影响.但这种影响作用仪表现在汉字认知加工的较低层面。具体本研究而言,纵横输入法和拼音输入法对汉字认知加工的“形”和“音”均存在影响,但前者侧重于“形”.而后者侧重于“音”。笔者认为其直接原因是学生为提高汉字输入速度所付出的额外练习(相比于输入速度低的学生)所导致的.输入法充当了一种作用载体。  相似文献

Skilled actions are commonly assumed to be controlled by precise internal schemas or cognitive maps. We challenge these ideas in the context of skilled typing, where prominent theories assume that typing is controlled by a well-learned cognitive map that plans finger movements without feedback. In two experiments, we demonstrate that online physical interaction with the keyboard critically mediates typing skill. Typists performed single-word and paragraph typing tasks on a regular keyboard, a laser-projection keyboard, and two deconstructed keyboards, made by removing successive layers of a regular keyboard. Averaged over the laser and deconstructed keyboards, response times for the first keystroke increased by 37%, the interval between keystrokes increased by 120%, and error rate increased by 177%, relative to those of the regular keyboard. A schema view predicts no influence of external motor feedback, because actions could be planned internally with high precision. We argue that the expert knowledge mediating action control emerges during online interaction with the physical environment.  相似文献

This study analyzed the quantitative relationship between keytapping times and ergonomic principles in typewriting skills. Keytapping times and key-operating characteristics of a female subject typing on the Qwerty and Dvorak keyboards for six weeks each were collected and analyzed. The results showed that characteristics of the typed material and the movements of hands and fingers were significantly related to keytapping times. The most significant factors affecting keytapping times were association frequency between letters, consecutive use of the same hand or finger, and the finger used. A regression equation for relating keytapping times to ergonomic principles was fitted to the data. Finally, a protocol for design of computerized keyboard layout based on the regression equation was proposed.  相似文献

Digital writing devices associated with the use of computers, tablet PCs, or mobile phones are increasingly replacing writing by hand. It is, however, controversially discussed how writing modes influence reading and writing performance in children at the start of literacy. On the one hand, the easiness of typing on digital devices may accelerate reading and writing in young children, who have less developed sensory-motor skills. On the other hand, the meaningful coupling between action and perception during handwriting, which establishes sensory-motor memory traces, could facilitate written language acquisition. In order to decide between these theoretical alternatives, for the present study, we developed an intense training program for preschool children attending the German kindergarten with 16 training sessions. Using closely matched letter learning games, eight letters of the German alphabet were trained either by handwriting with a pen on a sheet of paper or by typing on a computer keyboard. Letter recognition, naming, and writing performance as well as word reading and writing performance were assessed. Results did not indicate a superiority of typing training over handwriting training in any of these tasks. In contrast, handwriting training was superior to typing training in word writing, and, as a tendency, in word reading. The results of our study, therefore, support theories of action-perception coupling assuming a facilitatory influence of sensory-motor representations established during handwriting on reading and writing.  相似文献

Drawing typists' attention to their hands by asking them to type only letters assigned to the left or the right hand disrupts their performance, slowing the rate of typing and increasing errors. In this article we test the hypothesis that slowing occurs because typists watch their hands to determine which hand types which letter. Skilled typists were cued to type letters of one hand or of both hands while they could view their hands on the keyboard and while their vision was blocked by a box placed over the keyboard. Typing was slower when letters of one hand were typed than when letters of both hands were typed, and the slowing was greater when the hands were covered than when they were not. This supports the hypothesis that slowing occurs because typists watch their hands. However, typists were able to type letters of one hand when the keyboard was covered, so typists must have monitored kinesthetic information as well.  相似文献

Theories of spelling (Margolin, 1984; Nolan & Caramazza, 1983) propose a working memory system for storing order and identity information of letters during the spelling process. Capacity limitations related to the use of such a graphemic buffer were explored. Participants had to type words backwards. Longer pauses between key presses were assumed to signal points at which graphemic buffer contents were refreshed. Five- and six-letter words were divided by a major pause into chunks of two and three letters, partly coinciding with syllables. Articulatory suppression had no effect on performance. Increasing the length of the stimuli to seven to eight letters resulted in major pauses occurring at syllable boundaries, and performance becoming vulnerable to articulatory suppression but not foot tapping. Forward typing resulted in a similar pause pattern. The results suggest that chunks of approximately three letters can be handled at any one time. For short words the task seems to rely on non-phonological modes of coding, whereas longer words appear to require the use of a phonological code, possibly for keeping track of progress through the word.  相似文献

The authors investigated the importance of boundaries between phonemes, syllables, onsets and rimes, and morphemes in English spelling. They analyzed oral spelling data from a previous sample of 17 college students to predict time between consecutive letters (pause time) on the basis of the presence or absence of each linguistic boundary. The authors used a parallel approach to analyze pause times of 30 college students when typing individual words and when typing words in an essay. For oral and typed spellings of individual words, syllable boundaries significantly predicted pause times. Phoneme boundaries also predicted pause times in typed spellings of individual words. For typing essays, only onset-rime boundaries significantly predicted pause times. The results support the importance of syllables in the spelling of individual words. Further, the results suggest that spelling in the context of writing is a qualitatively different process than is spelling individual words by dictation.  相似文献

The graphemic representations that underlie spelling performance must encode not only the identities of the letters in a word, but also the positions of the letters. This study investigates how letter position information is represented. We present evidence from two dysgraphic individuals, CM and LSS, who perseverate letters when spelling: that is, letters from previous spelling responses intrude into subsequent responses. The perseverated letters appear more often than expected by chance in the same position in the previous and subsequent responses. We used these errors to address the question of how letter position is represented in spelling. In a series of analyses we determined how often the perseveration errors produced maintain position as defined by a number of alternative theories of letter position encoding proposed in the literature. The analyses provide strong evidence that the grapheme representations used in spelling encode letter position such that position is represented in a graded manner based on distance from both-edges of the word.  相似文献

键盘时间精度的一个图示法研究   总被引:4,自引:0,他引:4  
刘祖祥  朱滢 《心理学报》2001,34(6):21-29
以4个实验,用图示法对键盘的时间精度作了比较分析。实验1表明PES心理实验系统反应键和键盘都有良好的时间精度。实验2表明键盘的时间精度具有很大的个体差异,范围从1-2毫秒到40多毫秒,其中PS2的键盘普遍不理想。实验3表明键盘的时间精度不受转接器和计算机主频的影响。实验4使用了3名操作者,证实了这种方法的效果基本不受操作者个体差异的影响。研究演示了图示法在计算机控制的心理学实验中确定仪器的时间精度的作用,提示了实验中需要针对具体的实验条件判断时间精度是否符合实验要求,来确定是否选用特殊的反应键或者选择何种键盘作为反应的方式。  相似文献

The QWERTY keyboard mediates communication for millions of language users. Here, we investigated whether differences in the way words are typed correspond to differences in their meanings. Some words are spelled with more letters on the right side of the keyboard and others with more letters on the left. In three experiments, we tested whether asymmetries in the way people interact with keys on the right and left of the keyboard influence their evaluations of the emotional valence of the words. We found the predicted relationship between emotional valence and QWERTY key position across three languages (English, Spanish, and Dutch). Words with more right-side letters were rated as more positive in valence, on average, than words with more left-side letters: the QWERTY effect. This effect was strongest in new words coined after QWERTY was invented and was also found in pseudowords. Although these data are correlational, the discovery of a similar pattern across languages, which was strongest in neologisms, suggests that the QWERTY keyboard is shaping the meanings of words as people filter language through their fingers. Widespread typing introduces a new mechanism by which semantic changes in language can arise.  相似文献
