One of the central concerns in theories of reading skills is the role of phonology in access to word meaning. The present study focused on this issue in Chinese to examine the extent to which phonology affects Chinese character recognition. Two naming experiments were conducted with a phonologically mediated semantic priming paradigm, and the relative frequencies of semantic associates of the targets and their homophones were manipulated systematically. Analyses showed that a semantic associate produced robust priming on target naming at 57- and 250-msec. stimulus onset asynchronies, but only the low frequency homophones of high frequency semantic associates facilitated target naming at a 250-msec. stimulus onset asynchrony. These results indicate the role of phonology is neither obligatory nor efficient in access to Chinese character meaning, contradicting the key assumptions of the lexical constituency model. A revised parallel access model that emphasizes visual access to semantics is suggested as a more plausible account.  相似文献

The purpose of this study was to evaluate the rider position at walk and trot as a function of rider skill level by analyzing joint angles. Participants included three advanced riders and six beginners, and training was conducted for one hour, twice a week for 24 weeks. In the walk stage of the beginners’ group, the elbows and shoulders sustained postures comparable to those of the advanced riders group; the trunk tilted forwards at first, but later it tilted slightly behind the vertical. The knee, ankle, and left–right angle kept stable postures after 12 weeks of training (p < .05). The front-rear (FR) angle of the beginners group improved during training, but it was still lower than the advanced riders group after 24 weeks of training (p < .05). At trot, while the knee angle measurement of the beginners’ group was similar to the advanced riders, the ankle joint sustained a forward point posture. The ankle joint maintained dorsiflexion posture with 83.9° ± 5.3 in the advanced riders group, while the beginners group had plantar flexion posture with 98.7° ± 6.0. This study suggested that the correlation between the joint and body segment angles could be an important indicator in the evaluation of rider proficiency.  相似文献

儿童2岁时的不顺从对4~11岁间社会适应的预测   总被引:1,自引:1,他引:0  
采用实验室观察、母亲报告和教师报告,对138名随机抽取的北京市2岁儿童进行追踪,考察2岁时的不顺从行为对4岁、7岁和11岁时社会适应的影响。结果表明:(1)2岁时的消极不顺从行为可正向预测7岁时母亲报告的外显问题行为、教师报告的攻击性-学习问题和11岁时母亲报告的学习问题。(2)2岁时的拒绝/协商行为可正向预测4岁时母亲报告的多动。(3)2岁时的反抗行为可正向预测11岁时教师报告的内隐问题行为。  相似文献

The genetic counseling profession is expanding globally, and many countries, such as South Korea, are in the early stages of developing programs to prepare healthcare professionals specifically trained as genetic counselors. However, little research has investigated the concerns of South Korean patients and family members that have genetic conditions. The present study assessed their concerns by accessing and analyzing messages posted to websites devoted to genetic conditions. Eighteen websites were accessed—1 website concerns general genetic conditions, and 17 concern specific conditions. A sample of 700 messages was translated into English and analyzed using grounded theory analysis. Three major themes and 30 categories were extracted. The themes are: 1) Medical Concerns (e.g., clinical symptoms, diagnosis, prognosis, recurrence risk, prevention, inheritance); 2) Psychosocial Concerns (e.g., emotions, social stigma, social support); and 3) Management Concerns (e.g., therapy and alternative treatments, education, financial support, nutrition, medical facilities, folk remedies). The findings provide insight into the types of information and genetic counseling services that might benefit South Korean individuals and family members.  相似文献

The present study examined whether 6‐ and 9‐month‐old Caucasian infants could categorize faces according to race. In Experiment 1, infants were familiarized with different female faces from a common ethnic background (i.e. either Caucasian or Asian) and then tested with female faces from a novel race category. Nine‐month‐olds were able to form discrete categories of Caucasian and Asian faces. However, 6‐month‐olds did not form discrete categories of faces based on race. In Experiment 2, a second group of 6‐ and 9‐month‐olds was tested to determine whether they could discriminate between different faces from the same race category. Results showed that both age groups could only discriminate between different faces from the own‐race category of Caucasian faces. The findings of the two experiments taken together suggest that 9‐month‐olds formed a category of Caucasian faces that are further differentiated at the individual level. In contrast, although they could form a category of Asian faces, they could not discriminate between such other‐race faces. This asymmetry in category formation at 9 months (i.e. categorization of own‐race faces vs. categorical perception of other‐race faces) suggests that differential experience with own‐ and other‐race faces plays an important role in infants’ acquisition of face processing abilities.  相似文献

Very few studies have examined the effects of both religious affiliation and religiosity on mortality at the same time, and studies employing multiple dimensions of religiosity other than religious attendance are rare. Using the newly created General Social Survey-National Death Index data, our report contributes to the religion and mortality literature by examining religious affiliation and religiosity at the same time. Compared to Mainline Protestants, Catholics, Jews, and other religious groups have lower risk of death, but Black Protestants, Evangelical Protestants, and even those with no religious affiliation are not different from Mainline Protestants. While our study is consistent with previous findings that religious attendance leads to a reduction in mortality, we did not find other religious measures, such as strength of religious affiliation, frequency of praying, belief in an afterlife, and belief in God to be associated with mortality. We also find interaction effects between religious affiliation and attendance. The lowest mortality of Jews and other religious groups is more apparent for those with lower religious attendance. Thus, our result may emphasize the need for other research to focus on the effects of religious group and religious attendance on mortality at the same time.  相似文献

The authors investigated the effects of reading different types of online comments about a company on people's attitude change based on individual's prior attitude toward the company. Based on Social Judgment Theory, several hypotheses were tested. The results showed that the effects of online comments interact with individuals’ prior attitudes toward a corporation. People with a strong negative attitude toward a corporation were less influenced by other's online comments than people with a neutral attitude in general. However, people with a prior negative attitude were more affected by refutational two-sided comments than one-sided comments. The results suggest that the effects of user generated content should be studied in a holistic manner, not only by investigating the effects of online content itself, but also by examining how others’ responses to the content shape or change individuals’ attitudes based on their prior attitudes.  相似文献

Instructional applications (apps) are educational software programs that can be accessed via mobile technologies (e.g., iPad, smartphone) and used to help students acquire various academic skills, including mathematics. Although research suggests that app-based instruction (AI) can be effective, there is a paucity of research comparing AI, to teacher-directed instruction (TDI) or to a combination of instructional approaches (CI) involving both AI and TDI in tandem. In an alternating treatments design, we compared AI, TDI, and CI conditions during instruction targeting multiplication facts with six students with learning disabilities. Results were inconsistent across students, and no condition emerged as consistently better than the others. Students completed social validity rating scales, and all approaches were favored by at least one student. Our results support findings from previous research involving similar comparisons between these instructional formats in which no (or minimal) differences across conditions were detected. We conclude that there may not be a meaningful difference between the outcomes achieved using AI, TDI, or CI for many students. Results are discussed in terms of directions for the future research.  相似文献
