Two experiments are presented that examine how the visual characteristics of Japanese words influence eye movement behaviour
during reading. In Experiment 1, reading behaviour was compared for words comprising either one or two kanji characters. The
one-character words were significantly less likely to be fixated on first-pass, and had significantly longer overall reading
times, than the two-character words. In Experiment 2, reading behaviour was compared for two-kanji character words, for which
the first character was either visually simple or visually complex (determined by the number of strokes). Visual complexity
significantly influenced total word reading times and the probability of the individual visually simple/complex characters
being fixated on first pass. Additional analyses showed no preferred viewing position for two-kanji character words. Overall,
the study provides experimental evidence of an influence of specific visual characteristics of Japanese words on eye movement
behaviour during reading, as shown by both fixation probabilities and reading times. The findings must be explained by processing
at (or beyond) a visual level impacting on eye movement behavior during reading of Japanese text. 相似文献

The present study examined whether Japanesereaders activate phonological information whenreading kanji compound words and sentences andif so, how they do it. Experiment 1 usedtwo-kanji compound words in a lexical decisiontask to study phonological processing at thelexical level. When nonwords werepseudo-homophones (/roR hi/ in placeof the real word /roR hi/), reactiontimes were longer and more errors occurred thanwith nonwords in the control group(/saku hi/). Experiment 2required participants to detect misspellings(i.e., incorrect kanji combinations) oftwo-kanji compound stimuli embedded insentences. In the detection task of misspelledkanji, no homophonic effect was apparent. Experiment 3 used a semantic decision task. Included in this task were semantically similarbut incorrect kanji compound words used asfillers in sentences (e.g.,meaning `The building you can see over there was facilitated by my friend' instead of designed) as well as the sentences used inExperiment 2. Results from Experiment 3indicated that participants could reject asentence as incorrect more quickly whenpseudo-homophones were embedded in thesentences rather than nonwords. These resultssuggest that readers activate phonologicalinformation of two-kanji compound words whenreading for comprehension but not for simpleproofreading. 相似文献

Visual processing of verbal and nonverbal stimuli in adolescents with reading disabilities 总被引：7，自引：0，他引：7
This study investigated whether a group of children with reading disabilities (RD) were slower at processing visual information in general (compared to a group of children of comparable age and a group of children of comparable reading level), or whether their deficit was specific to the written word. Computerized backward masking and temporal integration tasks were used to assess the speed of visual information processing. Stimulus complexity (simple, complex) and type (verbal, nonverbal) were varied, creating a 2 x 2 matrix of stimulus conditions: simple nonverbal, complex nonverbal, simple verbal, and complex verbal. Adolescents with RD demonstrated difficulties in processing rapidly presented verbal and nonverbal visual stimuli, although the effect was magnified when they were processing verbal stimuli. Thus, the results of this study suggest that some youth with reading disabilities have visual temporal processing deficits that compound difficulties in processing verbal information during reading. 相似文献

Some previous studies of visual word recognition have reported an interaction between visual field and word length (measured by number of letters), such that recognition is affected more by word length for words presented in the left than for words presented in the right visual field. However, when manipulating serial position of letters in words to measure length effects, there are also reports of symmetrical word length effects in the two visual fields. Here we report two experiments, presenting four‐ and seven‐letter words, suggesting that the serial position and length effects in the hemispheres are separable and task dependent. For tasks that rely more heavily on letter‐level processing such as letter search (Experiment 1), performance in both hemifields showed similar effects of serial position; however, when comparing four‐ and seven‐letter words, an effect of word length was evident only in the left visual field, in line with the well‐established interaction between word length and hemifield. An interaction between word length and hemifield was confirmed for the same stimuli when they were employed in a lexical decision task, which forced whole‐word processing (Experiment 2). We conclude that the effects of serial position and number of letters in the two visual fields are separable, and are selectively affected by task type. 相似文献

Two experiments were conducted to investigate the time course of semantic and phonological access in naming kanji and kana words. Japanese adults quickly named single words written in kanji and the same words written in kana in one session, and translated them into English in another session. In both experiments using nouns (Experiment 1) and verbs (Experiment 2), words were named faster in kana than in kanji but were translated faster in kanji than in kana. These findings were interpreted to suggest that kana words are closer to phonology while kanji words are closer to meaning. The optimum solutions obtained by the simplex method showed that semantic access takes place 10 to 19 msec earlier in kanji words than in kana words, whereas phonological access takes place 27 to 31 msec earlier in kana words than in kanji words. A possible difference between kanji nouns and verbs is briefly discussed in terms of phonological access time. 相似文献

This study examined age-group differences in eye movements among third-grade, fifth-grade, and adult Japanese readers. In Experiment 1, Japanese children, but not adults, showed a longer fixation time on logographic kanji words than on phonologically transparent hiragana words. Further, an age-group difference was found in the first fixation duration on hiragana words but not on kanji words, suggesting character-type-dependent reading development in Japanese children. Examination of the distributions of saccade landing positions revealed that, like adults, both third and fifth graders fixated more on kanji than on hiragana characters, which suggests that even young children utilize the same oculomotor control strategy (the kanji targeting strategy) as Japanese adults. In Experiment 2, we examined whether the proportion of kanji characters in a text affected adult reading performance. Japanese adults made more refixations and regressions in texts with a high proportion of hiragana characters. The results of both experiments suggest that differences between kanji and kana affect the reading efficiency of school-age children and that maturation of reading skills allows adults to optimize their strategy in reading kanji and kana mixed texts. 相似文献

This study examined the extent to which mora deletion (phonological analysis), nonword repetition (phonological memory), rapid
automatized naming (RAN), and visual search abilities predict reading in Japanese kindergartners and first graders. Analogous
abilities have been identified as important predictors of reading skills in alphabetic languages like English. In contrast
to English, which is based on grapheme-phoneme relationships, the primary components of Japanese orthography are two syllabaries—hiragana
and katakana (collectively termed “kana”)—and a system of morphosyllabic symbols (kanji). Three RAN tasks (numbers, objects,
syllabary symbols [hiragana]) were used with kindergartners, with an additional kanji RAN task included for first graders.
Reading measures included accuracy and speed of passage reading for kindergartners and first graders, and reading comprehension
for first graders. In kindergartners, hiragana RAN and number RAN were the only significant predictors of reading accuracy
and speed. In first graders, kanji RAN and hiragana RAN predicted reading speed, whereas accuracy was predicted by mora deletion.
Reading comprehension was predicted by kanji RAN, mora deletion, and nonword repetition. Although number RAN did not contribute
unique variance to any reading measure, it correlated highly with kanji RAN. Implications of these findings for research and
practice are discussed. 相似文献

Two experiments were conducted investigating the role of visual sequential memory skill in the word recognition efficiency of undergraduate university students. Word recognition was assessed in a lexical decision task using regularly and strangely spelt words, and nonwords that were either standard orthographically legal strings or items made from words with internal transposed letters. Symbol memory was evaluated in a recognition procedure in which sequences of three to five unfamiliar complex symbols were presented, each followed by a subsequent array containing the symbols either in the same order or with an order transposition. In Experiment 1, there was no independent contribution of symbol memory to either word or nonword processing independently of the ability to discriminate the symbols from one another. In Experiment 2, although symbol memory made a significant contribution to word recognition independently of symbol discrimination and letter identification for two conditions??long strangely spelt words and short transposed-letter items, the effects were extremely small. It was concluded that non-verbal visual sequential memory skill does not play a central role in underpinning efficiency of word recognition in experienced adult readers. 相似文献

Three experiments are reported that investigate the cognitive processes underlying contextual and isolated word reading. In Phase 1, undergraduate participants were exposed to 75 target words under three conditions. The participants generated 25 words from definitions, read 25 words in context and read 25 in isolation. In Phase 2, volunteers completed either an explicit recall task (Experiment 1), an implicit word stem completion task (Experiment 2) or both tasks (Experiment 3). Our findings provide converging evidence that contextual and isolated word reading elicit different patterns of cognitive processing. Specifically, Experiments 1–3 demonstrated that words read in context were remembered similarly to words generated from definitions: words from both conditions were recalled more frequently in the surprise memory task and selected less often to complete the word stems in the implicit memory task. The opposite pattern was noted for words read in isolation. Reading in context is discussed in terms of its greater reliance on semantic processing, whereas isolated word reading is discussed in relation to perceptually driven processes. 相似文献

This study investigated the development of rapid visual object categorization. N = 20 adults (Experiment 1), N = 21 five to six-year-old children (Experiment 2), and N = 140 four-, seven-, and eleven-month-old infants (Experiment 3; all predominantly White, 81 females, data collected in 2013–2020) participated in a fast periodic visual stimulation electroencephalographic task. Similar categorization of animal and furniture stimuli emerged in children and adults, with responses much reduced by phase-scrambling (R2 = .34–.73). Categorization was observed from 4 months, but only at 11 months, high-level cues enhanced performance (R2 = .11). Thus, first signs of rapid categorization were evident from 4 months, but similar categorization patterns as in adults were recorded only from 11 months on. 相似文献

Instructors often show rhythmic movements with speech in video lectures. However, the effects of these movements have not been tested in video lectures with an instructor and visual learning material. Results of Experiment 1 showed students in the beat gestures and head nods conditions showed significantly less attention to the visual learning material, more attention to the instructor, whereas in the beat gestures + head nods condition drew significantly more attention to both. In Experiment 2 we tested whether the complexity of the visual learning material moderated the effects of rhythmic movements on students’ learning. When the presentation was simple, students in the head nods + beat gestures condition showed more positive interaction, and significantly better recall and transfer. The results have implications for video designing: if an instructor and simple learning material are visible, she is encouraged to show beat gestures and head nods to mark important information. 相似文献

This study examined the effectiveness of three imagery learning strategies for acquiring different outcomes when individuals received visual instructional information varying in visual stimulus complexity. Each of the strategies (copy, relational, and hierarchical) varied in amount of cognitive organization imposed on encoded information during learning. The levels of information to be acquired were: list learning, spatial learning, general concepts, and relational concepts. It was found that the hierarchical strategy was generally more effective in processing the different levels of information than the relational strategy or the copy strategy. The visual complexity variable was presented as a slide-tape-instructional program about the parts and operation of the human heart. The visual types varied from simple (line drawings) to complex (photographs). Analysis yielded a complex relationship between stimulus complexity and strategy. 相似文献

It has been claimed that the visual component of audiovisual media dominates young children's cognitive processing. This experiment examines the effects of input modality while controlling the complexity of the visual and auditory content and while varying the comprehension task (recall vs. reconstruction). 4- and 7-year-olds were presented brief stories through either audio or audiovisual media. The audio version consisted of narrated character actions and character utterances. The narrated actions were matched to the utterances on the basis of length and propositional complexity. The audiovisual version depicted the actions visually by means of stop animation instead of by auditory narrative statements. The character utterances were the same in both versions. Audiovisual input produced superior performance on explicit information in the 4-year-olds and produced more inferences at both ages. Because performance on utterances was superior in the audiovisual condition as compared to the audio condition, there was no evidence that visual input inhibits processing of auditory information. Actions were more likely to be produced by the younger children than utterances, regardless of input medium, indicating that prior findings of visual dominance may have been due to the salience of narrative action. Reconstruction, as compared to recall, produced superior depiction of actions at both ages as well as more constrained relevant inferences and narrative conventions. 相似文献

Deaf children who are learning to read are essentially learning a second language that may be transcribed in different ways, for example, using an alphabet, such as the Roman one used in written English, or logography, such as Japanese kanji. How do deaf adults from cultures using different writing systems memorize linguistic and visual material? Two experiments were carried out to answer this question. Two predictions were made: first, that Japanese deaf persons would outscore their English-language counterparts in memory for words, due to a possible direct processing from visual to semantic codes with kanji; second, that Japanese deaf persons would outscore their English-language counterparts in memory for abstract designs, due to prolonged use of a highly visual writing system. The first hypothesis was rejected; the second was accepted. 相似文献

A closer look at split visual attention in system- and self-paced instruction in multimedia learning
Two experiments examined visual attention distribution in learning from text and pictures. Participants watched a 16-step multimedia instruction on the formation of lightning. In Experiment 1 (N = 90) the instruction was system-paced (fast, medium, slow pace), while it was self-paced in Experiment 2 (N = 31). In both experiments the text modality was varied (written, spoken). During learning, the participants’ eye movements were recorded. Results from both experiments revealed that learners spent more time studying the visualizations with spoken text than those with written text. In written text conditions learners consistently started reading before alternating between text and visualization; moreover, they spent more time reading the text than inspecting the visualizations. While in Experiment 1 additional time that was made available in conditions with a slow or medium instruction pace was spent inspecting visualizations, in Experiment 2 longer learning times resulted from reading the text more intensively. With respect to learning outcomes (retention, transfer, and visual memory) Experiment 1 revealed an effect of text modality for visual memory only. In Experiment 2 no modality effects were found. Instruction pace was hardly related to learning outcomes. Overall, the results confirm prior findings suggesting that the distribution of visual attention in multimedia learning is largely guided by the text. 相似文献

The present study investigated the way in which the activation of semantic representations at the morpheme level affects the processing of two-kanji (morpheme) compound words. Three types of Japanese two-kanji compound words were used as stimulus items: (1) words consisting of two kanji representing opposite concepts (e.g., long + short = length), (2) words consisting of two kanji representing similar concepts (e.g., soft + flexible = pliable), and (3) control words consisting of two closely bound kanji (e.g., wild + field = wilderness). Words consisting of kanji of opposite concepts (M = 768 ms for LD and M = 645 ms for naming) were processed more slowly for lexical decision, but not for naming, than words with kanji of similar concepts (M = 743 ms for LD and M = 636 ms for naming), both of which were, furthermore, processed more slowly for lexical decision and naming than the control compound words (M = 716 ms for LD and M = 590 ms for naming). These results were explained in the framework of the multiple-level interactive-activation model as follows. Because kanji morphemes of opposite and similar concepts are semantically activated both as morpheme units and compound word units, semantic representations of the two morphemes and the compound word which they create compete with each other at the concept level, which slows down lexical decision and naming of the compound word. 相似文献
