The quality of implicit morphological knowledge in adult Hebrew readers with developmental dyslexia was investigated. The priming paradigm was used to examine whether these adults extract and represent morphemic units similarly to normal readers during online word recognition. The group with dyslexia as a whole did not exhibit priming with visual presentation as opposed to both age- and reading-level controls. Priming was absent when the prime and target words shared a morpheme and even when the prime and the target were identical. Only the students with phonological dyslexia, who exhibited relatively good performance in the orthographic judgment task, exhibited repetition priming but not morphological priming. Strong repetition and morphological priming effects were found for participants with dyslexia when the stimuli were auditory. The implications of the dissociation between visual and auditory priming for the locus of the deficit in morphological processing during word recognition are discussed. 相似文献

Individuals' relative awareness of thematic and taxonomic relations is influenced by factors such as language and background knowledge. Relatively weak in Korean language skills and also having relatively limited social opportunities, Korean deaf adolescents might be different from hearing adolescents in how they make decisions in taxonomically and thematically associated entities represented by pictures and words. Experiment 1 indicated that deaf adolescents had longer reaction times than hearing adolescents in a forced-choice decision-making task. Both deaf and hearing adolescents had shorter reaction times and higher accuracies with pictures than with words, but deaf adolescents' differences were bigger than those of hearing adolescents. Experiment 2 further showed that deaf adolescents had lower accuracies than hearing adolescents in a priming task of living-nonliving categorization. Both deaf and hearing adolescents had shorter reaction times with taxonomic than with thematic categories, but deaf adolescents' difference was bigger than that of hearing adolescents. In conclusion, Korean deaf adolescents were aware of thematic and taxonomic relations less than hearing adolescents in general. They were more likely than hearing adolescents to show the advantage of pictures over words in their performance in conceptual activities and to prefer taxonomic to thematic associations for written words in Experiment 2. 相似文献

Deaf children's referential messages to mother 总被引：1，自引：0，他引：1
Deaf children 6-10 years of age, from oral or bimodal educational programs, were tested in 2 tasks. In the first, they were required to describe a designated picture from a set of 4 pictures so that their mother could identify the intended referent from the 4 alternatives. In the second, they studied a single picture and were subsequently required to identify it from a set of 4 related pictures. Despite greater hearing loss, bimodally educated children provided more differentiated messages than did orally educated children. Bimodally educated children also provided better reformulations of messages that were initially inadequate. Although mothers of orally educated children received inferior messages, they were as successful at selecting the correct referent as were mothers of bimodally educated children. Both groups of deaf children performed at near perfect levels on the picture recognition task, suggesting that performance differences were attributable to differential message formulation skill as opposed to differential visual processing of the referential array. 相似文献

The effect of stimulus rotation was assessed in four Guinea baboons (Papio papio), using pictures of familiar human faces presented in a computerized go/no-go task. In Experiment 1, 2 baboons were initially trained to discriminate upright faces, and 2 others were trained to discriminate upside-down faces. For the two groups, postlearning discrimination was impaired when the training faces were rotated 180°. In Experiment 2, upright and upside-down priming faces appeared prior to the display of target faces. For the two groups, response times were faster when the prime and the target faces had the same orientations than when they were depicted under different orientations. Finally, Experiments 3 and 4 identified variations in facial contours as the most salient discriminative cue controlling performance in 2 baboons. Altogether, our results provide no evidence that the baboons processed the pictures as representations of faces. It is suggested that the effect of rotation derived from the encoding of the pictorial faces as meaningless mono-oriented shapes, rather than as natural human faces. 相似文献

This study investigated whether text-picture integration is facilitated when text and pictures are presented simultaneously instead of sequentially. Participants memorized general and specific sentences and pictures. It was expected that due to text-picture integration, participants should falsely recognize specific versions of the sentences and pictures even after having studied only their general versions before. Sentences and pictures were presented simultaneously or sequentially with the picture either preceding or following the corresponding sentence. Contrary to expectations, text-picture integration was only observed for picture recognition and was not influenced by temporal contiguity. Findings are explained by the use of simple materials that did not sufficiently tax working-memory capacity to allow for any benefit of a simultaneous text-picture presentation to occur. 相似文献

A small sample of 20 hearing students and 20 students who are deaf and hard‐of‐hearing participated in this study, which compared their performances on two measures of metacognition. The first measure required participants to visually analyse real‐life pictures and then to choose a response from four options (voiced or signed) indicating which was the best explanation of what was depicted. The second measure required participants to look at five pictures and then to point to the picture that was different. Results identified no significant differences between the performances of the two groups of students on either measure. Males in both groups performed at comparable levels on the two measures, whereas females who were hearing and those who were deaf or hard‐of‐hearing performed significantly better on the visual–voiced measure than on the visual–visual measure. Limitations of this study and recommendations for future research are discussed. 相似文献

Repetition priming was used to examine whether children with dyslexia bias a lexical–semantic pathway when reading words aloud. For the dyslexic group (n = 18, age 9.4–11.8 years), but not for age‐matched controls (n = 18, age 9.2–12.4 years), reaction times when naming pictures were faster after naming the corresponding word. A reading age‐matched control group (n = 24, age 6.8–8.9 years) showed similar priming effects to the children with dyslexia. The magnitude of repetition priming was greater for children with dyslexia with poor nonword reading and slower picture naming. Assuming repetition priming of picture naming is contingent on accessing lexical phonology via semantics, the results suggest less‐skilled normal and disordered readers show a stronger bias towards a lexical– semantic pathway during word reading than skilled readers, and the severity of the phonological representations deficit modulates the strength of that bias in children with dyslexia. 相似文献

Repeated exposure to a single target type (sequential priming) during visual search for multiple cryptic targets commonly improves performance on subsequent presentations of that target. It appears to be an attentional phenomenon, a component of the searching image effect. It has been argued, however, that if searching image is an attentional process, sequential priming should also interfere with performance on subsequent nonprimed targets, and such interference has never been unequivocally demonstrated. In blue jays (Cyanocitta cristata) searching in an operant apparatus for targets derived from images of cryptic moths, detection performance was strongly facilitated in the course of a sequential prime but was relatively unaffected by sequences of mixed target types. Detection accuracy in subsequent probe trials was enhanced by priming with targets of the same type, whereas accuracy on cryptic probes following priming with a more conspicuous target was significantly degraded. The results support an attentional interpretation of searching image. 相似文献

The present study aimed to investigate the development of automatic phonological processes involved in visual word recognition during reading acquisition in French. A visual masked priming lexical decision experiment was carried out with third, fifth graders and adult skilled readers. Three different types of partial overlap between the prime and the target were contrasted: orthographic and phonological overlap (O+P+; ren-RENDRE [give] pronounced /?ɑ?/-/?ɑ?d?/ respectively), orthographic overlap (O+P?; re-RENDRE pronounced /??/-/?ɑ?d?/ respectively), or without orthographic and phonological overlap with the beginning of the target, namely unrelated (UR; pi-RENDRE pronounced /pi/-/?ɑ?d?/, respectively). The number of letters was controlled throughout the priming conditions. The results showed an interaction between grade and priming condition in children. In third graders, the results displayed a masked phonological priming effect (the O+P+ condition was compared to the O+P? condition) but not a masked orthographic priming effect (the O+P? condition was compared to the UR condition). On the contrary, in fifth graders, the results showed a masked orthographic priming effect but not a masked phonological priming effect. Adult skilled readers displayed the same pattern as fifth graders. These results are interpreted in the multiple-route model of reading development. 相似文献

Infants’ transfer of information from pictures to objects was tested by familiarizing 9‐month‐olds (N = 31) with either a color or black‐and‐white photograph of an object and observing their preferential reaching for the real target object versus a distractor. One condition tested object recognition by keeping both objects visible, and the other tested object representation by hiding both objects. On visible trials, infants reached more for the distractor, indicating they recognized the target object from its picture. On hidden trials, infants reached more for the target object, suggesting they formed a continued representation of the object based on its picture. Photograph color had no effect. Infants thus show picture‐to‐object transfer by 9 months with preferential reaching, even with black‐and‐white pictures. 相似文献

The term ‘modality effect’ in multimedia learning means that students learn better from pictures combined with spoken rather than written text. The most prominent explanations refer to the split attention between visual text reading and picture observation which could affect transfer of information into working memory, maintenance of information in working memory or the effective size of working memory. The assumption of a continuous need for split attention is questionable, however. Learners can keep pictorial information in working memory, when they have seen the picture before, especially if they have higher prior knowledge. Instead of suffering from a permanent split attention, learners frequently show tendencies to simply ignore pictures. This suggests guiding learners towards picture analysis by picture-related text paragraphs. We assume that these paragraphs are associated with stronger modality effects than content-related paragraphs, especially if the pictures are new to learners. These assumptions were tested in an experiment with 120 students learning about volcanism from illustrated text consisting of segments each including a content-related paragraph followed by a picture-related paragraph describing the accompanying visualization. Content-related and picture-related paragraphs were presented as visual or auditory texts leading to 2x2 conditions of text presentation. Picture novelty was manipulated by presenting a picture throughout the whole segment or only when the picture-related paragraph was read. As expected, picture-related paragraphs were associated with stronger modality effects than content-related paragraphs if picture novelty is high. The distinction between different kinds of paragraphs seems to be important for the prediction of modality effects. 相似文献

A Gorilla with ‘Grandpa's Eyes’: How Children Interpret Visual Texts—A Case Study of Anthony Browne's Zoo 总被引：1，自引：0，他引：1
This article explores the multilayered nature of a single picture book by Anthony Browne and the sophisticated responses (including their own pictures) children aged 4–11 bring to interpreting such a text. Emphasis is laid on the high-level cognitive skills involved in reading visual images and links are made between seeing and thinking. Some features of the children's understanding are examined in detail; for example, how they interpret visual imagery and deal with a variety of challenging artistic features, and how their drawings show knowledge and feelings they are not yet able to articulate. The findings also suggest that some children who are not yet confident at reading print have developed impressive capacities for analysing image. 相似文献

Research into picture effects on encoding of verbal material has paid little attention to the effects of picture changes. In this experiment, it was found that adults’ recall of the spoken text in a TV news item was impaired by mid‐sentence picture editing. In contrast, both 11‐12 year old and 14‐15 year old children's recall was enhanced by rapid cutting, so long as the accompanying pictures were relevant to the verbal text. Both adults’ and younger children's recall was better with some of the experimentally‐manipulated material than it was with the original broadcast version of the news item. However, 14‐15 year olds performed best with the original version.
It is suggested that viewers are differentially sensitive to unintended production effects and that their processing of verbal information can be disrupted by inappropriately‐timed picture cuts. Research on picture‐text relationships in audio‐visual material needs to take account of picture‐timing, as well as picture content, and television editing procedures may need to be tailored more specifically to suit the intended audience. 相似文献

Second-grade children, third-grade children, and adults judged whether pictures were members of a positive or negative memory set while trying to ignore irrelevant words printed inside the pictures. There were 3 types of picture-word relation. In 1 condition, the words corresponded to the pictures. In a second condition, the pictures and words were incongruent, but the words corresponded to the correct response (e.g., with dog and horse the positive set pictures, a picture of a dog containing the word "horse"). In the third condition, the pictures and words were incongruent and corresponded to conflicting responses. For all 3 subject groups, the type of picture-word relation reliably affected response latencies, indicating that subjects automatically processed the irrelevant printed words. 相似文献

Sequential priming refers to speeded visual search when target identity or location is repeated within a trial sequence. In two experiments with pigeons, we addressed the relative contributions of stimulus-driven factors and learned expectancies to this effect. Pigeons pecked at targets during trialwise presentations of visual-search displays. Random-sequence conditions minimized the role of expectancy by introducing same-target or same-location trial sequences unpredictably. Blocked-sequence conditions added predictability by regular repetition of target and/or location over trials. Intertrial interval varied from 0.5 to 3 sec. The findings revealed significant reductions in reaction time during predictable target or location sequences compared with unpredictable repetitions within random contexts. Stimulus-driven factors do not seem to have an important role in many instances of sequential priming. Expectancy-based priming of target and location followed similar patterns. 相似文献

Metacognitive performance of four groups of students (hearing high-achieving, hearing average-achieving, hearing under achieving, and deaf and hard of hearing) in first through third grade in the United Arab Emirates was examined and compared. Metacognition was measured using analyses of pictures depicting real-life problematic events, situations, and behaviors. Participants drew on their ability to apply problem solving and logical reasoning through visual analysis and discrimination of test materials rather than through verbal analysis. Results revealed that metacognition is influenced by students' age. Older students scored significantly higher on the metacognitive measure than younger students. Further analysis indicated that hearing high-achieving students scored significantly higher on the test than the other three groups when the age variable was controlled for. Deaf and hard of hearing students performed similarly to age-matched hearing students in applying reasoning skills to real-life situations. 相似文献

Developmental changes in the understanding of implied motion in two-dimensional pictures. 总被引：1，自引：0，他引：1
The power of various pictorial movement cues in eliciting a reading of movement was studied to determine the relationship between the ease with which a picture is interpreted and the degree to which the picture retains the structure of reality. Movement was indicated in 2 ways: pictorial conventions indicated movement by lines, blurs, and vibration marks; and pictorial postures indicated movement by figures which were isomorphic with the postures involved in real movement. Preschoolers, first graders, sixth graders, and college students were asked to label and sort pictures of human figures as "moving" or "still". Members of the 2 young groups did not classify pictures with conventional cues as "moving" as often as they did pictures with postural cues. Members of the 2 older groups classified both types of pictures as "moving". Since postural cues for movement are recognized at an earlier age than conventional cues, those that are more similar to reality may be easier to understand. 相似文献

Summary The present study investigated the relationships of meaningfulness, picture detail, and presentation mode on visual learning.
Subjects, 123 broadcasting students at Brooklyn College, viewed slides of animal pictures previously classified by judges
into high-and low-meaningful groups. All Ss saw both high-and low-meaningful stimulus items. Half saw the stimulus items as
full-color pictures while the other half saw them as line drawings. In addition, one-third saw the stimulus items as pictures
presented alone, one-third saw them as pictures with each animal name printed underneath its picture, and one-third saw the
pictures (without printed names) accompanied by the spoken animal name as each slide was shown. Following presentation of
stimulus slides, Ss were shown a series of full-color test slides containing dummy items randomly intermixed with stimulus
items. During two showings of test slides, Ss first indicated those animals recognized from the learning trial and second,
wrote down those animal names they knew.
Results included significant main effects on recognition accuracy for meaningfulness and presentation mode in addition to
significant interactions for meaningfulness-by-mode and mode-by-picture-detail. A significant main effect of presentation
mode resulted for correctly named stimulus items. Three significant main effects (meaningfulness, picture detail, and mode)
and one significant interaction (mean-ingfulness-by-picture-detail) were obtained on error scores. 相似文献
