The present study examines deaf and hearing children's spelling of plural nouns. Severe literacy impairments are well documented in the deaf, which are believed to be a consequence of phonological awareness limitations. Fifty deaf (mean chronological age 13;10 years, mean reading age 7;5 years) and 50 reading-age-matched hearing children produced spellings of regular, semiregular, and irregular plural nouns in Experiment 1 and nonword plurals in Experiment 2. Deaf children performed reading-age appropriately on rule-based (regular and semiregular) plurals but were significantly less accurate at spelling irregular plurals. Spelling of plural nonwords and spelling error analyses revealed clear evidence for use of morphology. Deaf children used morphological generalization to a greater degree than their reading-age-matched hearing counterparts. Also, hearing children combined use of phonology and morphology to guide spelling, whereas deaf children appeared to use morphology without phonological mediation. Therefore, use of morphology in spelling can be independent of phonology and is available to the deaf despite limited experience with spoken language. Indeed, deaf children appear to be learning about morphology from the orthography. Education on more complex morphological generalization and exceptions may be highly beneficial not only for the deaf but also for other populations with phonological awareness limitations. 相似文献

In three experiments, subjects were required to make texture judgments about abrasive surfaces. Touch and vision provided comparable levels of performance when observers attempted to select the smoothest of three surfaces, but bimodal visual and tactual input led to greater accuracy. The superiority of bimodal perception was ascribed to visual guidance of tactual exploration. The elimination of visual texture cues did not impair bimodal performance if vision of hand movements were permitted. It is suggested that touch may preempt vision when both sources of texture information are simultaneously available. The results support the notion that perception is normally multimodal, since restriction of the observer to either sense in isolation produces lower levels of performance. 相似文献

Adult subjects learned to identify bars differing in orientation. The bars were presented either tactually or haptically. In the first experiment, learning was followed by a transfer test with body posture changed by 90 deg. That is, if subjects originally learned with body upright, the transfer test was carried out with body reclined. Results of the transfer test indicated original learning of the tactually presented bars was done with respect to a body reference system and original learning of the haptically presented bars was done with respect to an environmental or gravity based reference system. In the second experiment, learning was followed by a transfer test using both a change of body posture and a change of stimulus modality from tactual to haptic or vice versa. Performance in this transfer test is interpreted in terms of a conceptual mediation hypothesis. 相似文献

This study investigated peripheral vision (at least 30° eccentric to fixation) development in profoundly deaf children without cochlear implantation, and compared this to age-matched hearing controls as well as to deaf and hearing adult data. Deaf and hearing children between the ages of 5 and 15 years were assessed using a new, specifically paediatric designed method of static perimetry. The deaf group (N = 25) were 14 females and 11 males, mean age 9.92 years (range 5-15 years). The hearing group (N = 64) were 34 females, 30 males, mean age 9.13 years (range 5-15 years). All participants had good visual acuity in both eyes (< 0.200 LogMAR). Accuracy of detection and reaction time to briefly presented LED stimuli of three light intensities, at eccentricities between 30° and 85° were measured while fixation was maintained to a central target. The study found reduced peripheral vision in deaf children between 5 and 10 years of age. Deaf children (aged 5-10 years) showed slower reaction times to all stimuli and reduced ability to detect and accurately report dim stimuli in the far periphery. Deaf children performed equally to hearing children aged 11-12 years. Deaf adolescents aged 13-15 years demonstrated faster reaction times to all peripheral stimuli in comparison to hearing controls. Adolescent results were consistent with deaf and hearing adult performances wherein deaf adults also showed significantly faster reaction times than hearing controls. Peripheral vision performance on this task was found to reach adult-like levels of maturity in deaf and hearing children, both in reaction time and accuracy of detection at the age of 11-12 years. 相似文献

Whereas the average age of earliest reportable personal memory among adults is 3 to 3½, there is considerable individual and group variability in the age of earliest autobiographical memory. Some of the variability is thought to be attributable to differential narrative socialisation. In the present research we tested the hypothesis that by virtue of later exposure to language, individuals born deaf to hearing parents will have earliest memories from later in life, relative to hearing individuals. The average age of single earliest identifiable memory for adults who are deaf and adults who are hearing did not differ. Nevertheless, adults who are deaf were found to have less dense representations of early autobiographical memories and to include in their narrative reports fewer categories of information, including visual-spatial information, relative to hearing adults. Participants' ratings of their memories on a number of dimensions were found to have low utility in predicting the content of autobiographical reports from both early and later in life (i.e., after age 10 years). 相似文献

We describe a patient LS, profoundly deaf in both ears from birth, with underdeveloped superior temporal gyri. Without hearing aids, LS displays no ability to detect sounds below a fixed threshold of 60 dBs, which classifies him as clinically deaf. Under these no-hearing-aid conditions, when presented with a forced-choice paradigm in which he is asked to consciously respond, he is unable to make above-chance judgments about the presence or location of sounds. However, he is able to make above-chance judgments about the content of sounds presented to him under forced-choice conditions. We demonstrated that LS has faint sensations from auditory stimuli, but questionable awareness of auditory content. LS thus has a form of type-2 deaf hearing with respect to auditory content. As in the case of a subject with acquired deafness and deaf hearing reported on a previous occasion, LS’s condition of deaf hearing is akin in some respects to type-2 blindsight. As for the case of type 2 blindsight the case indicates that a form of conscious hearing can arise in the absence of a fully developed auditory cortex. 相似文献

An anchoring design was used to investigate correspondence between visual and tactual scaling of complexity when two samples of random polygons served as stimulus forms. The results support the conclusion that within an adjustment for differential acuity between vision and active touch input is referred to a common perceptual mechanism. 相似文献

The role of rhythm in the speech intelligibility of 18 hearing-impaired children, aged 15 years with hearing losses from 40 to 108 db, was investigated. Their perceptual judgement of visual rhythm sequences was superior to that of the hearing controls, but their scores were not correlated with their speech intelligibility. 相似文献

This study investigated the influence of some characteristics of the task, the model, and the observer, in the estimation errors of adults while judging children's affordances. One hundred and eighteen adults, divided in 4 height groups, estimated height and vertical reaching capability of 3 girls (3.55-, 4.74- and 7.06-years old), in the presence and in the absence of the model. Constant errors (CE) (estimation-real value), absolute percent errors (APE) (|1 − estimation/real value| × 100), and error tendency (underestimations, right judgments, or overestimations) were calculated. A model and a condition effect were verified on APE. APE for the younger model were greater than for the other models (p < 0.001), and APE in the absence of the model were greater than in her presence (p < 0.05). Generally, adults underestimated height (51.8% of underestimations vs. 32.3% of overestimations) and overestimated reachability (51.3% of overestimations vs. 37.7% of underestimations). The overestimation of reachability was more notorious for the younger model, which might reflect adults' difficulty to consider the specificity of younger children's body proportions. Actually, the overestimation bias may suggest that adults perceive young children as on the basis of adult's geometrical proportions. 相似文献

Children first learned by means of a teaching program to discriminate a circle from relatively flat ellipses. Children in the control group then proceeded into a program which gradually reduced the difference between the circle and the ellipses. They advanced to a finer discrimination when they made a correct choice, and reversed to an easier discrimination after making errors ("backup" procedure). The children made relatively few errors until they approached the region of their difference threshold (empirically determined under the conditions described). When they could no longer discriminate the forms, they learned other bases for responding that could be classified as specifiable error patterns. Children in the experimental group, having learned the preliminary circle-ellipse discrimination, were started at the upper end of the ellipse series, where it was impossible for them to discriminate the forms. The backup procedure returned them to an easier discrimination after they made errors. They made many errors and reversed down through the ellipse series. Eventually, most of the children reached a point in the ellipse series where they abandoned their systematic errors and began to make correct first choices; then they advanced upward through the program. All of the children advanced to ellipse sizes that were much larger than the ellipse size at the point of their furthest descent. 相似文献

Summary Ninety six Ss were subjected to lateral body tilt, ranging from 10° to 90° to the right and to the left, and indicated the visual vertical (by means of a luminescent rod) and the tactual vertical (by means of a metal bar) in a darkroom. There were significant differences for deviations of apparent from true vertical in both series between body tilt to the right versus to the left. With tilts to the right, apparent vertical deviated more opposite the direction of tilt, the E-phenomenon, or less in the direction of tilt, the A-phenomenon, as compared with tilts to the left.This study was supported, in part, by a Public Health Service Research Grant, MH 00348, from the National Institute of Mental Health, while the author was a NATO research fellow at Clark University, Worcester, MA; and in part by a Federal Grant, MR HD 06276, to the Children's Hospital Medical Center, while the author was a research fellow in child psychiatry at Harvard University, School of Medicine, Boston, MA. 相似文献

348 adolescents, 176 male and 172 female, were administered six different spatial tests. Awareness of figural proportion, figural memory, and figure-ground perception contributed significantly to performance on spatial visualization tests but not to performance on spatial orientation tests. Similarly, severity of hearing loss was correlated with scores on visualization tests but not on spatial-orientation tests. 相似文献

Two experiments were conducted to investigate the effects of quantity and depth of processing on children's time perception. These experiments tested the appropriateness of two adult time-perception models (attentional and storage size) for younger ages. Children were given stimulus sets of equal time which varied by level of processing (deep/shallow) and quantity (list length). In the first experiment, 28 children in Grade 6 reproduced presentation times of various quantities of pictures under deep (living/nonliving categorization) or shallow (repeating label) conditions. Students also compared pairs of durations. In the second experiment, 128 children in Grades K, 2, 4, and 6 reproduced presentation times under similar conditions with three or six pictures and with deep or shallow processing requirements. Deep processing led to decreased estimation of time. Higher quantity led to increased estimation of time. Comparative judgments were influenced by quantity. The interaction between age and depth of processing was significant. Older children were more affected by depth differences than were younger children. Results were interpreted as supporting different aspects of each adult model as explanations of children's time perception. The processing effect supported the attentional model and the quantity effect supported the storage size model. 相似文献

Summary It has appeared in our experiments that certain absolute spacial directions play a dominant r?le in the drawings even of young
children, but that frequently the dominant directions are not determined by absolute position but by their significance in
a given form.
