Effects of public posting,goal setting,and oral feedback on the skills of female soccer players

We evaluated the effects of public posting, goal setting, and oral feedback on the skills of 3 female high school soccer players during practice scrimmages. The dependent variables were the percentage of appropriate responses when the player (a) kept and maintained possession of the ball, (b) moved to an open position during a game restart (e.g., goal or corner kick), and (c) moved to an open position after passing the ball. We also assessed the extent to which changes in practice performances generalized to games. A social validity questionnaire was completed by both players and coaches to assess the acceptability of the intervention's goals, procedures, and outcomes. Results indicate that the intervention was effective in improving performances during practice scrimmages but produced limited generalization to game settings.     

Feedback and its effectiveness in a computer-aided personalized system of instruction course

In a computer-managed version of Keller's personalized system of instruction, students received frequent feedback from more advanced students within the course. Overall accuracy of student-provided feedback was 87%, and students complied with 61% of the feedback.     

The assumed effects of positive feedback paired with success on motivation to do a task: The cases of characters with high and low initial levels of interest

This study investigated the effects of positive feedback paired with success on motivation to do a task, and examined whether this differed according to whether the person performing the task had a high or low initial level of interest in that task. Subjects (448 junior college students) were asked to rate (from 0–10) the level of motivation of characters in four different stories. Subjects believed that positive feedback would encourage the character to do a task regardless of initial level of interest. However, when positive feedback could not be expected, ratings for motivation fell. Ratings for motivation were further analyzed when no positive feedback could be expected, either after an earlier experience of positive feedback paired with success or after success only (no feedback). In the case of a low initial level of interest, it was assumed that motivation would be increased after positive feedback, but in the case of a high initial level of interest motivation was assumed to be decreased by an earlier experience of positive feedback paired with success. These results suggest that the effect of positive feedback paired with success will differ according to the level of a person's initial interest.     

Emotional and motivational reactions to failure: the role of illusions of control and explicitness of feedback

Previous research has found that illusions of control (IOC) can buffer against the emotional consequences of failure and may increase persistence in the face of failure. Theoretical analyses suggest that IOC are most closely related to a better mood and higher motivation if failure feedback is open to reinterpretation. Two experiments were conducted to test the hypothesis that explicitness (vs. ambiguousness) of failure feedback moderates the consequences of IOC following a failure experience. In accord with predictions, it was found that IOC were subsequently related to a better mood (Study 1) and higher persistence (Study 2) if individuals received ambiguous task-inherent failure feedback. In contrast, explicit failure feedback seemed to neutralize the beneficial effects of IOC. These results are discussed with respect to the adaptiveness of IOC.

当前医患关系紧张的经济学分析及对策

从经济学的角度对医患关系紧张的形成机制进行分析,揭示目前医患关系紧张的恶性循环是"正反馈"效应的负面体现。要形成医患关系的良性循环,首要的任务就是从制度层面上来找突破口,并以提倡患者理性医疗和加强医生的人文教育作为支持,使"正反馈"效应得到正面体现,从而实现医患关系的和谐。     

第二语言学习中的反馈

在第二语言学习中,反馈指针对学习者的言语行为给予学习者的评价性信息。该文阐释了反馈的概念、类型以及反馈在第二语言学习中的角色,并从反馈的时机与对象、对学习者注意力的引导、学习者认知资源的限制、情感支持等方面分析了有效反馈的特征,最后对反馈研究对我国第二语言学习与教学的意义及以后的研究方向进行了探讨     

音乐情感交流研究中的透镜模型

介绍了研究音乐情感交流的透镜模型和透镜模型等式及其在音乐教育中的应用。透镜模型旨在解释演奏者如何通过多种或然且部分过剩的线索表达情感,听者如何使用这些线索识别演奏者表达的情感。透镜模型等式（LME）将演奏者和听者线索利用的回归模型联系起来。以透镜模型为理论基础,LME为数学基础产生了用于改善音乐演奏中的情感交流的认知反馈法（CFB）,即在演奏者演奏结束之后,向演奏者反馈其线索利用与欣赏者的线索利用相比较的结果,以提高演奏者与听者线索利用的一致性     

Supporting teacher use of interventions: effects of response dependent performance feedback on teacher implementation of a math intervention

This study examined general education teachers’ implementation of a peer tutoring intervention for five elementary students referred for consultation and intervention due to academic concerns. Treatment integrity was assessed via permanent products produced by the intervention. Following verbal instructions, intervention implementation by four teachers was consistently low or exhibited a downward trend whereas one teacher’s moderate implementation co-occurred with student gains. When classroom training was conducted with four teachers exhibiting low integrity, all teachers improved implementation. After accurately implementing the intervention for three training sessions with classroom training, response dependent performance feedback was provided when teachers independently used the intervention below 100% integrity, as determined by review of permanent products. With response dependent performance feedback, three of the four teachers implemented the intervention at levels above the verbal training performance, whereas implementation for one teacher increased following discussion of an upcoming school team meeting. Student math scores improved during intervention.     

Career Research Interests and Training of Genetic Counseling Students

Research is important to validate clinical services, provide information on the effectiveness of practice techniques, and develop the knowledge base of a clinical profession. Genetic counseling students from American Board of Genetic Counseling (ABGC) accredited training programs were surveyed to determine their career research interests and interest in pursuing a hypothetical doctoral degree in genetic counseling. Genetic counseling program directors were surveyed to assess the emphasis on research training within their programs. A substantial number (46%, n = 92) of genetic counseling students are interested in performing research in their careers and many (40%, n = 80) would pursue a doctoral degree in genetic counseling if it was available. Students and directors from programs with a thesis requirement reported a significantly higher emphasis on career research preparation than those from programs without a thesis requirement. The results of this study indicate that future genetic counselors are interested in contributing to the research base that will advance the field. This study suggests a need to strengthen research training within ABGC accredited graduate programs and explore the development of a doctoral degree option in genetic counseling.     

Neural correlates of visuospatial consciousness in 3D default space: Insights from contralateral neglect syndrome

One of the most compelling questions still unanswered in neuroscience is how consciousness arises. In this article, we examine visual processing, the parietal lobe, and contralateral neglect syndrome as a window into consciousness and how the brain functions as the mind and we introduce a mechanism for the processing of visual information and its role in consciousness. We propose that consciousness arises from integration of information from throughout the body and brain by the thalamus and that the thalamus reimages visual and other sensory information from throughout the cortex in a default three-dimensional space in the mind. We further suggest that the thalamus generates a dynamic default three-dimensional space by integrating processed information from corticothalamic feedback loops, creating an infrastructure that may form the basis of our consciousness. Further experimental evidence is needed to examine and support this hypothesis, the role of the thalamus, and to further elucidate the mechanism of consciousness.
