Handwriting isolated cursive letters in young children: Effect of the visual trace deletion     

《Learning and Instruction》2021

This study assesses the handwriting of isolated cursive letters in five-year-old children and the effect of a modification in visual feedback. Sixty-four children copied twelve cursive letters with an inking pen and a non-inking pen. Reducing visual feedback decreased the mean number of penlifts, and increased mean velocity and fluency. However, it increased the size of the letters (trajectory length) and reduced their quality. We suggest that processing visual feedback of the emerging visual trace may interrupt the fluency of the movement, while writing without seeing the trace may place greater emphasis on motor control and the use of somatosensory feedback. This study supplies reflection about sensory feedback and the moment when it should be provided in handwriting instruction. Practitioners should be aware that variation in the writing environment (surface, tools …) modifies sensory feedback and affects handwriting learning (gesture and outcome) in different manner.  相似文献   

The effect of anticipated achievement feedback on students' semantic processing as indicated by the N400 cloze effect     

《Learning and Instruction》2017

The present study examined the effects of anticipated achievement feedback on students' semantic processing on the neural level, using event-related brain potentials (ERPs). Participants (N = 79) anticipated either self-referential or normative achievement feedback regarding an announced upcoming test. Additionally, their performance expectations (low vs. no expectations) were orthogonally manipulated. Subsequently, students' on-line semantic processing was assessed by measuring the N400 cloze effect, a component in the EEG signal of which the amplitude is associated with semantic processing. Within the low performance-expectation condition, no effect of anticipated feedback on semantic processing was found. Within the no-performance-expectation condition, participants anticipating self-referential feedback showed a more widely distributed N400 cloze effect than participants anticipating normative feedback. The results confirmed the hypothesis that the mere expectation of a particular type of feedback can affect students' semantic processes.  相似文献

运算放大器工作状态的判断及分析     

吴恒玉  唐民丽 《孝感职业技术学院学报》2006,9(1):91-92

在电子技术教学中,分析运算放大器系统时,应根据运算放大器系统的反馈情况,判断它的工作状态;分析工作状态时,要充分考虑运放系统是处于线性区还是饱和区。线性区可按虚短或虚地原则处理,饱和时不能按虚短原则处理,应用“虚短”和“虚地”时应注意“虚短”是“虚地”的特殊形式。  相似文献   

Realism Matters: The Role of Perceived Realism in The Biggest Loser     

Yan Tian 《Communication Research Reports》2016,33(4):303-309

This study investigated implications of viewing The Biggest Loser, NBC’s popular reality television show. Using online survey data collected from 613 participants, results suggest that exposure to the program is positively associated with perceived realism of the program, which in turn is positively associated with developing internal weight locus of control. Meanwhile, internal weight locus of control is positively associated with audience members’ exercise behavior, meaning the higher level of internal weight locus of control the audience members develop, the more likely they are to engage in physical exercise. This study offers evidence that health-related reality television might be a useful tool to influence audience members’ cognitions on health issues, which could potentially lead to healthy lifestyles.  相似文献   

Perceived Message Effectiveness Predicts Information-Seeking Behavior     

James Price Dillard  Yerheen Ha 《Communication Research Reports》2016,33(4):356-362

This study examined whether perceived message effectiveness (PE) predicted information-seeking behavior in the topical domain of colon cancer. Participants (N = 277) viewed one of three video messages (news, testimonial, and animation) that advocated screening for colon cancer. Information-seeking behavior was operationalized as reading time for a subsequent message about colon cancer. The proposed mediation model successfully reproduced the pattern of data, thereby providing evidence that PE predicts behavior via intention.  相似文献   

A coach’s political use of video-based feedback: a case study in elite-level academy soccer     

Michael Booroff  Lee Nelson  Paul Potrac 《Journal of sports sciences》2016,34(2):116-124

This paper examines the video-based pedagogical practices of Terry (pseudonym), a head coach of a professional junior academy squad. Data were collected through 6 in-depth, semi-structured interviews and 10 field observations of Terry’s video-based coaching in situ. Three embracing categories were generated from the data. These demonstrated that Terry’s video-based coaching was far from apolitical. Rather, Terry strategically used performance analysis technologies to help fulfil various objectives and outcomes that he understood to be expected of him within the club environment. Kelchtermans’ micropolitical perspective, Callero’s work addressing role and Groom et al.’s grounded theory were primarily utilised to make sense of Terry’s perceptions and actions. The findings point to the value of developing contextually grounded understandings of coaches’ uses of video-based performance analysis technology. Doing so could better prepare coaches for this aspect of their coaching practice.  相似文献   

Development and validation of the Perceived Game-Specific Soccer Competence Scale     

Hannele Forsman  Arto Gråstén  Minna Blomqvist  Keith Davids  Jarmo Liukkonen  Niilo Konttinen 《Journal of sports sciences》2016,34(14):1319-1327

ABSTRACT

The objective of this study was to create a valid, self-reported, game-specific soccer competence scale. A structural model of perceived competence, performance measures and motivation was tested as the basis for the scale. A total of 1321 soccer players (261 females, 1060 males) ranging from 12 to 15 years (13.4 ± 1.0 years) participated in the study. They completed the Perceived Game-Specific Soccer Competence Scale (PGSSCS), self-assessments of tactical skills and motivation, as well as technical and speed and agility tests. Results of factor analyses, tests of internal consistency and correlations between PGSSCS subscales, performance measures and motivation supported the reliability and validity of the PGSSCS. The scale can be considered a suitable instrument to assess perceived game-specific competence among young soccer players.  相似文献   

信息反馈与汉语修辞     

王玉仁 《锦州师范学院学报(哲学社会科学版)》2007,29(1):60-64

言语交际。信息传递，不都是简单的、单向的、固定的、一次性的。更多的。因此而更有现实意义和理论价值的，乃是那些复杂的、双向的、随机的、多次传递方能完成的。因此，判定某处修辞是成功的还是失败的，必须考察其在一个复杂的修辞流程中所起的作用，视其所造成的到底是正反馈还是负反馈。如若其所造成的是正反馈，那么，不管它多么生动、形象，都是失败的修辞；如若造成的是负反馈，那么，不管它多么朴拙、背谬，都是成功的修辞。  相似文献
