Early developmental psychologists viewed iconic representation as cognitively less complex than other forms of symbolic thought. It is therefore surprising that iconic signs are not acquired more easily than arbitrary signs by young language learners. One explanation is that children younger than 3 years have difficulty interpreting iconicity. The current study assessed hearing children's ability to interpret the meaning of iconic signs. Sixty-six 2.5- to 5-year-olds who had no previous exposure to signs were required to match iconic signs to pictures of referents. Whereas few of the 2.5-year-olds recognized the meaning of the iconic signs consistently, more than half of the 3.0-year-olds and most of 3.5-year-olds performed above chance. Thus, the ability to recognize the meaning of iconic signs gradually develops during the preschool years. Implications of these findings for sign language development, receptive signed vocabulary tests, and the development of the ability to interpret iconic symbols are discussed. 相似文献

Count us in: the role of schools and colleges in meeting the mental health needs of young people with learning disabilities 总被引:1,自引:0,他引:1
In December 2002, the Foundation for People with Learning Disabilities' Committee of Inquiry into the mental health needs of young people with learning disabilities produced its report.
Barry Carpenter, Chief Executive at Sunfield and Chair of the committee, and Hazel Morgan, head of the Foundation for People with Learning Disabilities, take this opportunity to share some insights into the workings of the committee and summarise the key findings. The committee drew evidence from a range of sources, but placed the voices and experiences of young people with learning disabilities at the centre of their proceedings. The committee's findings and recommendations were wide ranging and will have far-reaching implications, but there are immediate messages that schools and colleges should hear. It is upon these messages, taking account of pastoral provision, the curriculum, transition and inter-agency work, that Barry Carpenter and Hazel Morgan focus in this article. 相似文献

The design of motivational agents and avatars 总被引:1,自引:0,他引:1
Amy L. Baylor 《Educational technology research and development : ETR & D》2011,59(2):291-300
While the addition of an anthropomorphic interface agent to a learning system generally has little direct impact on learning,
it potentially has a huge impact on learner motivation. As such agents become increasingly ubiquitous on the Internet, in
virtual worlds, and as interfaces for learning and gaming systems, it is important to design them to optimally impact motivation.
The focus of this paper is on the design of agents and avatars (one’s self-representation as a visual agent) for enhancing
motivational and affective outcomes, such as improving self-efficacy, engagement and satisfaction, moderating frustration,
and/or improving stereotypes. Together with motivational messages and dialogue (which are not discussed here), the agent’s
appearance is the most important design feature as it dictates the learner’s perception of the agent as a virtual social model,
in the Bandurian sense. The message delivery, through a human-like voice with appropriate and relevant emotional expressions,
is also a key motivational design feature. More research is needed to determine the specifics with respect to the ideal agent
voice and the role of other nonverbal communication (e.g., deictic gestures) that may contribute to the agent’s role as an
embodied motivator, particularly in the long-term. 相似文献

A comprehensive, quantitative evaluation of an educational intervention program designed to reduce the attrition of minorities from the biological sciences was undertaken to ascertain whether such efforts adequately address the problem. Program participants had greater odds of persisting in basic math and science courses, and of graduating in biology, than did a comparison group, controlling for demographics and academic preparation. Undergraduate research greatly increased the odds of positive graduation outcomes. Program participants were also more likely to pursue graduate study than were university graduates overall. This evaluation demonstrates the value of such programs in increasing the representation of minorities in science. ? 2004 Wiley Periodicals, Inc. J Res Sci Teach 41: 861‐881, 2004. 相似文献

Pedagogical Agents as Learning Companions: The Role of Agent Competency and Type of Interaction 总被引:1,自引:0,他引:1
Yanghee Kim Amy L. Baylor 《Educational technology research and development : ETR & D》2006,54(3):223-243
This study was designed to examine the effects of the competency (low vs. high) and interaction type (proactive vs. responsive)
of pedagogical agents as learning companions (PALs) on learning, self-efficacy, and attitudes. Participants were 72 undergraduates
in an introductory computer-literacy course who were randomly assigned to one of four treatments: Low-Proactive, Low-Responsive,
High-Proactive, and High-Responsive. Results indicated a main effect for PAL competency. Students who worked with the high-competency
PAL in both proactive and responsive conditions achieved higher scores in applying what they had learned and showed more positive
attitudes toward the PAL. However, students who worked with the low-competency PAL reported significantly enhanced self-efficacy
beliefs in the learning tasks. Also, there was a main effect far PAL interaction type. A proactive PAL had a significantly
positive impact on recall. These different results on learning and motivational outcomes suggest that the competency and interaction
type of a PAL should be designed according to the desired learning and motivational goals. 相似文献

The Effect of Hearing Impairment on the Quality of Attachment and Mother-Toddler Interaction 总被引:1,自引:0,他引:1
In the present study, 41 hearing impaired and 41 hearing toddlers together with their hearing mothers were observed in Ainsworth's Strange Situation and during free play. Both security of attachment and ratings of maternal and toddler behavior during free play were remarkably similar for the hearing impaired and hearing dyads. In addition, security of attachment was related to the ratings of maternal and toddler behavior in a similar way for the hearing impaired and hearing toddlers. The results suggest that development of a secure attachment and maintaining a good mother-toddler relationship does not depend on normal language development during the toddler years. 相似文献

This longitudinal study examined how separation and family conflict mediated the effects of two acculturation variables (English language use and generational status) on substance use (alcohol, tobacco, and marijuana use) and deviant behavior outcomes in a Mexican American high school age sample. Structural equation modeling indicated that separation was a significant mediator of the relationship between acculturation and alcohol use, tobacco use, and deviant behavior. Family conflict mediated the effects of acculturation on marijuana use and deviant behavior. Model comparisons across gender groups suggested that generational status was an influential acculturation measure for females but not males. Additionally, English language use maintained a direct effect on marijuana use among females, whereas this relationship was mediated by separation for males. 相似文献
