The purpose of this study was to evaluate the effectiveness of using a video iPod as a prompting device for teaching three
job-related tasks to a young man with developmental disabilities in a community-based employment setting. The effectiveness
of the prompting device was evaluated using a multiple probe across behaviors design. Results indicated that the introduction
of the video iPod was associated with immediate and substantial gains in independent correct responding with an associated
decrease in the number of prompts given from a job coach. In addition, the participant used the video iPod independently.
Instructional implications and future research will be discussed. 相似文献

随着网络的日益普及,社交网站已成为人们活动的新领域和人际交往的新媒介。为探讨社交网站中不同的自我呈现方式、积极反馈与友谊质量的关系,采用问卷法对来自武汉市两所普通中学的817名10~19岁的学生进行调查,其中,男生423人,女生366人。研究采用偏差矫正的百分位Bootstrap法,使用Hayes(2012)编制的SPSS宏对中介效应进行检验,结果发现:(1)真实自我呈现和积极自我呈现与积极反馈、友谊质量显著正相关;(2)社交网站中的真实自我呈现既能直接预测青少年的友谊质量,也能通过积极反馈的中介作用对友谊质量产生影响,而积极自我呈现对青少年的友谊质量没有直接预测作用,只能通过积极反馈的完全中介作用对友谊质量产生影响。 相似文献

Most studies on the evaluation of teaching focus on the input (teacher traits) or the output (student-generated products) of the teaching and learning processes. This article is based on a case study that examines the three components of teaching and learning: input, output and process. It presents a framework for collecting quantitative and qualitative data on the quality of instruction, assessment and feedback, and learning environment in college composition courses to complement the feedback provided by the end-of-course student evaluations of teaching for the purpose of monitoring, guiding, and improving instruction. 相似文献

<正>式反馈是近年来发展出的一项提高临床实践的有效方法,它是指利用标准化的治疗效果测量工具,系统监控当事人评定的治疗进展情况,并将当事人的进展信息提供给治疗师,以供其随后的治疗作参考之用。治疗效果问卷评定系统和合作-改变效果管理系统是目前使用较为广泛的正式反馈测量工具。正式反馈的使用不仅能够改善偏离预期进展当事人(not on track,NOT)的治疗效果,提高当事人治疗进展的速率,同时还能够促进治疗双方更好的合作。正式反馈的作用机制可以使用概念化反馈干预理论和交互作用论进行解释。影响正式反馈作用效果的因素包括反馈本身的特征、当事人初始症状严重程度、治疗师方面因素以及治疗的时长等。未来研究需关注正式反馈的研究方法、作用机制及其跨文化研究的差异。 相似文献

The current study examined the outcome of presenting multiple secondary targets in learning trials for individuals with autism spectrum disorder. We compared conditions in which (a) a secondary target was presented in the antecedent and consequence of trials, (b) two secondary targets were presented in the consequence of trials, (c) one secondary target was presented in the consequence of each trial, and (d) no additional targets were presented trials. The participants acquired the majority of secondary targets. Presenting one or multiple secondary targets per trial, regardless of the location of these secondary targets, increased the efficiency of instruction in comparison to a condition with no secondary target. 相似文献

Visual cues can be used to train walking patterns. Here, we studied the performance and learning capacities of healthy subjects executing a high-precision visuomotor walking task, in an augmented reality training set-up. A beamer was used to project visual stepping targets on the walking surface of an instrumented treadmill. Two speeds were used to manipulate task difficulty. All participants (n = 20) had to change their step length to hit visual stepping targets with a specific part of their foot, while walking on a treadmill over seven consecutive training blocks, each block composed of 100 stepping targets. Distance between stepping targets was varied between short, medium and long steps. Training blocks could either be composed of random stepping targets (no fixed sequence was present in the distance between the stepping targets) or sequenced stepping targets (repeating fixed sequence was present). Random training blocks were used to measure non-specific learning and sequenced training blocks were used to measure sequence-specific learning. Primary outcome measures were performance (% of correct hits), and learning effects (increase in performance over the training blocks: both sequence-specific and non-specific). Secondary outcome measures were the performance and stepping-error in relation to the step length (distance between stepping target). Subjects were able to score 76% and 54% at first try for lower speed (2.3 km/h) and higher speed (3.3 km/h) trials, respectively. Performance scores did not increase over the course of the trials, nor did the subjects show the ability to learn a sequenced walking task. Subjects were better able to hit targets while increasing their step length, compared to shortening it. In conclusion, augmented reality training by use of the current set-up was intuitive for the user. Suboptimal feedback presentation might have limited the learning effects of the subjects. 相似文献

In modern times, Lamarck's view of evolution, based on inheritance of acquired traits has been superseded by neo-Darwinism, based on random DNA mutations. This article begins with a series of observations suggesting that Lamarckian inheritance is in fact operative throughout Nature. I then launch into a discussion of human intelligence that is the most important feature of human evolution that cannot be easily explained by mutational selection. Thus, we are smarter than demanded by our evolutionary experience as hunter-gatherers. The difficulty lies in the inability of neo-Darwinism to satisfactorily answer the following question: How can a large energy-costly set of genes, each member of which has little apparent benefit when first created individually, all gather into a permanent existence within a short time period in each and every member of a small population (that was dispersed and geographically isolated over a huge planet) who had a low reproductive output, a low rate of beneficial mutations, and a low level of genetic contact? The article concludes with a speculative but far-reaching epigenetic theory of intelligence that does not require DNA mutation as the exclusive source of evolutionary change. Instead, cranial feedback relating brain chemistry, as affected by brain activity including education, with the genome. When it comes to the fast rate of evolution, and the dissemination of the intelligence trait worldwide, cranial feedback could make all the difference. 相似文献

People tend to mimic the facial expression of others. It has been suggested that this helps provide social glue between affiliated people but it could also aid recognition of emotions through embodied cognition. The degree of facial mimicry, however, varies between individuals and is limited in people with autism spectrum conditions (ASC). The present study sought to investigate the effect of promoting facial mimicry during a facial-emotion-recognition test. In two experiments, participants without an ASC diagnosis had their autism quotient (AQ) measured. Following a baseline test, they did an emotion-recognition test again but half of the participants were asked to mimic the target face they saw prior to making their responses. Mimicry improved emotion recognition, and further analysis revealed that the largest improvement was for participants who had higher scores on the autism traits. In fact, recognition performance was best overall for people who had high AQ scores but also received the instruction to mimic. Implications for people with ASC are explored. 相似文献

“信任他人或者不信任他人?”是社会互动中经常面临一种行为决择, 直接影响着个体的社会生活。作为一种重要的社会信号机制, 信任是建立良好社会关系的基石, 它能够降低社会交易成本, 易化合作行为。为了探究个体在信任互动情境下大脑活动变化的时间动态特征, 采用事件相关电位技术记录了20名健康被试(充当信任者)完成重复性信任博弈任务(repeated Trust Game, rTG)时的脑电成分。行为结果发现个体选择信任的比例显著高于几率水平。电生理学结果表明, 决策阶段中不信任选择比信任选择诱发了更正的P2成分(150~250 ms), 差异波溯源分析定位于额中回(middle frontal gyrus, BA 46)和额下回(inferior frontal gyrus, BA 46)。反馈阶段中损失反馈比获益反馈诱发了更负的FRN成分(200~300 ms), 而获益反馈比损失反馈诱发了更短的P300潜伏期。本研究为理解人类信任博弈过程的动态加工时程提供了初步的神经电生理学证据。 相似文献
