Magnetic resonance imaging is a promising technological advance used for research and diagnosis of disease. The procedure has no risks, except when uncooperative patients require sedation. Four normal children participated in simulated scans to study the effects of (a) antecedent changes in the imaging environment and (b) operant conditioning of movement inhibition. Changing the environment can decrease movement, but operant contingencies were necessary to decrease movement to a level that, in most cases, would allow the procedure to occur without sedation.  相似文献

Instructive feedback involves presenting extra, non-target stimuli in the consequent events for children's responses. Two methods of presenting instructive feedback during direct instruction were compared. These methods involved presenting two extra stimuli on all trials, and presenting the two extra stimuli separately on alternating trials. Preschool students were taught coin combinations using a constant time delay procedure with instructive feedback stimuli added to both praise and correction statements. An adapted alternating treatments design was used to evaluate the two methods of presenting instructive feedback. The students were assessed to determine the extent to which instructive feedback stimuli were learned. The results indicate that students learned some of the instructive feedback stimuli and no consistent differences in the effectiveness of the two presentation methods were noted. Further, relationships between the two instructive feedback stimuli appeared to be established. Implications for instruction and future research are discussed.  相似文献

A performance feedback procedure was used to increase glove wearing by nurses in a hospital emergency room in situations in which contact with body fluids was highly likely. Infection-control nurses provided biweekly performance feedback to staff nurses on an individual private basis to inform them of the percentage of contact opportunities in which they wore gloves. Observations made prior to (baseline) and during feedback in a multiple baseline design across 4 subjects indicated that substantial increases in glove wearing in target situations occurred after implementation of the feedback program and that increases occurred across most of the specific situations in which glove wearing was advised. Percentage increases in glove wearing ranged from 22% to 49% across subjects. The results are discussed in terms of prevention of acquired immune deficiency syndrome (AIDS) by use of universal precautions.  相似文献

Writing progress notes represent a critical activity of practicing clinicians in a variety of settings. They provide a way for medical practitioners, insurance companies, and others to communicate in a timely fashion regarding ongoing clinical care. Previous research showed that intervention components like didactic training, using note templates, and feedback improved the quality of progress notes. At least two questions remain despite several studies already addressing progress note writing. First, previous research most often used multiple intervention components to improve progress notes. Thus, the relative impact of two common components of interventions, such as didactic training and feedback, is unclear. Second, previous research has not evaluated the acceptability of improved progress notes for the practitioners that actually utilize them. Thus, the purpose of the current study evaluated the components of didactic training and feedback on improved progress note writing for four direct staff employed by a psychiatric inpatient unit. A second purpose of this study was to evaluate the acceptability of the training procedures by both (a) the direct-care staff participating in this study and (b) four members of the psychiatric treatment team that used direct-care staff progress notes to inform their clinical care. Results showed that feedback was necessary to improve the accuracy of progress notes for three of four participants. The direct-care staff reported the training procedures as acceptable and the treatment team noted improvements in the quality of the progress notes after intervention. These data will be discussed in terms of ways to arrange effective training programs to improve direct-care staff's progress notes.  相似文献

Play provides children learning opportunities in the natural environment to acquire communication skills. While working to establish skills that may lead to additional leisure and social opportunities of children with autism spectrum disorder (ASD), procedures need to be both effective and efficient. One way to increase efficiency of teaching is through the use of instructive feedback (IF). Therefore, the purpose of the current study is to systematically replicate and extend previous research by examining if play behaviors emerge when using IF to teach conceptually related primary (i.e., tacts) and secondary targets (i.e., play skills). The results of the present study extend previous research by demonstrating the effectiveness of teaching tacts to individuals with ASD, and that using IF during tact training can help promote the acquisition of play skills.  相似文献

Although deep-level diversity among team members are often discussed as important catalysts of team creativity, little is currently understood about the impact of diversity in team members’ personality on team creativity and team satisfaction. We propose that diversity in team members’ agreeableness would reduce the effectiveness of creative teams through its impact on team conflict experienced. To test our hypotheses, we recruited 93 student teams to participate in a laboratory study where each member had their personality traits assessed before engaging in a team creativity task. We found that diversity in team members’ agreeableness was positively associated with team task conflict experienced which, in turn, was negatively associated with team creativity. Additionally, we found that diversity in team members’ agreeableness was positively associated with team relationship conflict, which, in turn, was negatively associated with team satisfaction. Implications and future directions are discussed.  相似文献

This study evaluated the use of video modeling and video modeling plus video feedback to enhance four adolescents' performance of a dance movement. Intervention was evaluated in a multiple baseline across participants design. This study found that video modeling enhanced performance from baseline, but the addition of video feedback produced further increases. For one participant, improvement was dependent on the perspective of the video model. Implications of these findings and suggestions for future research are discussed.  相似文献

Open-ended text questions provide better assessment of learner’s knowledge, but analysing answers for this kind of questions, checking their correctness, and generating of detailed formative feedback about errors for the learner are more difficult and complex tasks than for closed-ended questions like multiple-choice.The analysis of answers for open-ended questions can be performed on different levels. Analysis on character level allows to find errors in characters’ placement inside a word or a token; it is typically used to detect and correct typos, allowing to differ typos from actual errors in the learner’s answer. The word-level or token-level analysis allows finding misplaced, extraneous, or missing words in the sentence. The semantic-level analysis is used to capture formally the meaning of the learner’s answer and compare it with the meaning of the correct answer that can be provided in a natural or formal language. Some systems and approaches use analysis on several levels.The variability of the answers for open-ended questions significantly increases the complexity of the error search and formative feedback generation tasks. Different types of patterns including regular expressions and their use in questions with patterned answers are discussed. The types of formative feedback and modern approaches and their capabilities to generate feedback on different levels are discussed too.Statistical approaches or loosely defined template rules are inclined to false-positive grading. They are generally lowering the workload of creating questions, but provide low feedback. Approaches based on strictly-defined sets of correct answers perform better in providing hinting and answer-until-correct feedback. They are characterised by a higher workload of creating questions because of the need to account for every possible correct answer by the teacher and fewer types of detected errors.The optimal choice for creating automatised e-learning courses are template-based open-ended question systems like OntoPeFeGe, Preg, METEOR, and CorrectWriting which allows answer-until-correct feedback and are able to find and report various types of errors. This approach requires more time to create questions, but less time to manage the learning process in the courses once they are run.  相似文献

Organizational agility has become an increasing focus for companies and has led to the emergence of new developmental methods. This article presents the cross-evaluation as an approach to evaluating and developing inter-team interface efficacity. Though 360 degrees feedback collective processes are being evaluated, and during reflexive workshops they decide what improvements to make in their team functioning. Based on a literature review and more specifically on the theories of social identity and groupthink this article describes the scientific bases of the cross-evaluation method and the biases that can be involved and how to reduce them. It suggests new avenues of research and practical suggestions for practitioners about an inter-team development method.  相似文献

Previous research demonstrates the efficacy of behavioral skills training with a textual prompt to establish greetings and conversational skills. This study examined the efficacy of a brief intervention of textual prompts with performance feedback for increasing social niceties of adolescents and young adults with autism spectrum disorder in a simulated workplace. Target social niceties included “Do you have a minute?” when a participant initiated an interaction and “Thank you for your time” when a participant ended the interaction. Results revealed this intervention was effective for 7 of 9 participants. This study expands upon previous studies by showing the efficacy of a resource-efficient training on acquisition and generalization of social niceties by people with autism spectrum disorder.  相似文献
