移动窗口条件下聋生阅读过程中字词识别的实验研究

本研究采用移动窗口技术,以短文为实验材料,分别以单字呈现和多字呈现两种方式,对阅读技能水平较高和较低的聋生进行了实验,旨在验证和探讨聋生在汉语文章阅读过程中语音编码所起的作用。实验结果发现,聋生在短文阅读过程中存在语音激活的现象,但语音与字形所起的作用在不同实验中表现不同;聋生,特别是阅读能力较高的聋生,在阅读过程中,字形起到了关键的作用。     

Teaching Spelling of Social Studies Content Vocabulary Prior to Using the Vocabulary in Inclusive Learning Environments: An Examination of Constant Time Delay, Observational Learning, and Instructive Feedback

This study evaluated the effectiveness of using a 5 s constant time delay (CTD) procedure to teach the written spelling of social studies vocabulary words taken from the general education social studies content to students with mild disabilities. Subjects were 3 elementary students with mild disabilities. Instruction was delivered in a small group setting. Vocabulary words were different for each student, which allowed for observational learning by the other students in the group. Assessments of observational learning were conducted when each student attempted to spell their group-mate's words. Related instructive feedback (meaningful sentences containing the social studies vocabulary words) was presented in the consequent event of instructional trials. A multiple probe design across word sets was implemented to evaluate the effectiveness of the procedure. Results indicated that (a) CTD was reliably implemented and all students acquired the spelling of their own sets of 12 social studies vocabulary words with 100% accuracy and maintained this accuracy over time, (b) all students generalized their target spellings across settings and instructors, and (c) some observational and instructive feedback learning occurred for all students. Additionally, long-term maintenance of observational spellings decreased over time, and minor fluctuations in long-term maintenance of instructive feedback occurred.     

Learning to fear a second-order stimulus following vicarious learning

Vicarious fear learning refers to the acquisition of fear via observation of the fearful responses of others. The present study aims to extend current knowledge by exploring whether second-order vicarious fear learning can be demonstrated in children. That is, whether vicariously learnt fear responses for one stimulus can be elicited in a second stimulus associated with that initial stimulus. Results demonstrated that children's (5–11 years) fear responses for marsupials and caterpillars increased when they were seen with fearful faces compared to no faces. Additionally, the results indicated a second-order effect in which fear-related learning occurred for other animals seen together with the fear-paired animal, even though the animals were never observed with fearful faces themselves. Overall, the findings indicate that for children in this age group vicariously learnt fear-related responses for one stimulus can subsequently be observed for a second stimulus without it being experienced in a fear-related vicarious learning event. These findings may help to explain why some individuals do not recall involvement of a traumatic learning episode in the development of their fear of a specific stimulus.     

论班图拉观察学习理论的特征及其历史地位

该文从以下三个方面分析了班图拉观察学习理论的特征：（１）强化与认知的结合,（２）行为主义的建构论,（３）交互决定论。作者认为,班图拉对心理学的杰出贡献是他发掘了观察学习这一前人所忽视的学习形式,给了观察学习以应有的地位。作者认为,班图拉在其观察学习的研究中,注重社会因素的影响。以认知的术语阐述观察学习的过程与作用,且注重以人为被试的实验,因而对学习心理学的发展产生重要影响。     

Establishing books as conditioned reinforcers for preschool children as a function of an observational intervention

We tested the effects of an observational intervention (Greer & Singer-Dudek, 2008) on establishing children's books as conditioned reinforcers using a delayed multiple baseline design. Three preschool students with mild language and developmental delays served as the participants. Prior to the intervention, books did not function as reinforcers for any of the participants. The observational intervention consisted of a situation in which the participant observed a confederate being presented with access to books contingent on correct responses and the participant received nothing for correct responses. After several sessions of this treatment, the previously neutral books acquired reinforcing properties for maintenance and acquisition responses for all three participants.     

Observing home-visit quality with the home visit rating scales: Introduction to the special section

Evidence-based home-visiting programs aim to address one of the most important challenges facing our species—setting the next generation on a healthy path of development that prepares them for a future that is simultaneously uncertain and promising. Diverse research literatures have pointed to practices to effectively meet this challenge and better achieve the unfulfilled promise of home visiting by more effectively engaging parents in supporting their children's early development and well-being. Measures of home-visit quality practices drawn from social work, pediatric nursing, early childhood, and early intervention research literatures have identified building relationships with families and focusing on their strengths as effective, practices that are particularly important for vulnerable families. The articles in this special section used the Home Visit Rating Scales to examine stability in home-visit quality over time, study specific home-visiting processes linked with quality, validate a supervisor checklist of home-visiting implementation, and consider the home visit in relation to an array of indicators reflecting overall home-visiting program strength and stability. These articles exemplify progress in home-visiting research over recent decades, including advances in direct observational methods and measurement as well as examinations of home visiting as an observable process across various home-visiting program models and populations.

Short-term sentence recall: evidence for the contribution of acoustic-sensory information

To demonstrate that short-term sentence recall is based on conceptual and lexico-semantic information, Potter and Lombardi [J. Memory Lang. 29 (1990) 633] conducted a series of experiments using the intrusion paradigm, which combines short-term sentence recall and lexical priming. In the present paper, we employed the intrusion paradigm to demonstrate that acoustic-sensory information is involved in sentence regeneration as well. For this purpose, we presented sentences visually for silent reading (conceptual and phonological information) and reading aloud (conceptual, phonological, and--in addition--acoustic-sensory information). We demonstrated that less intrusions appeared in the reading aloud condition. This effect supports the assumption that, if available, acoustic-sensory information contributes to the regeneration process.
