视觉表象已经成为运动认知心理学的重要课题,关于视觉表象融入乒乓球运动实践方面的研究,均已经取得了很多丰富的研究成果。从视觉研究结论中已经证实了"视觉感知、视觉搜索与知觉技能的熟练程度"之间密切相关。因此,试就视觉表象融入乒乓球训练路径选择与训练作用展开讨论,阐述视觉感知对大脑中枢神经信息反射姿态的认知作用;视觉搜索对运动中信息快速处理协同的感知作用;视野能力对运动中信息时空范畴视觉甄别阈值的控制作用。为此,将视觉表象融入到乒乓球训练实践中,使其对视觉表象认知与转化实际训练效果等方面起到更大促进作用。  相似文献

共情缺陷是导致自闭症儿童社交障碍的重要因素。研究选取了28名3-7岁的自闭症和正常发展儿童,通过生理信号、面部表情和认知绩效等多模态数据的分析,探讨自闭症儿童共情过程中各阶段的特点,分析自闭症儿童共情缺陷的具体表现。研究发现,自闭症儿童的共情能力缺陷主要体现在较差的认知共情能力和较差的面部表情模仿能力;自闭症儿童的共情过程存在正常的自下而上的情绪分享过程和异常的自上而下的认知调节过程。因此,自闭症儿童共情能力的干预重点应聚焦认知调节过程中认知共情能力的提升和表情模仿能力的训练。  相似文献

正1.前言工作记忆与注意是心理学研究中两个重要的认知结构,人们时刻需要从视觉情境选择中选择有限的刺激进行加工,而工作记忆在注意选择的过程中扮演着关键角色。近些年来,关于工作记忆和注意偏向之间交互关系的研究逐渐成为社会热点,由于视觉信息加工系统的资源有限性,当视野中同时出现大量信息时,视觉注意只能选择与当前任务相关的有限信息。工作记忆对视觉搜索中注意偏向的选择起到非常重要的作用,不同工作记忆对注意  相似文献

To examine how visual attentional resources are allocated when learning from a complex animation about the cardiovascular system, eye movements were registered in the absence and presence of visual cues. Cognitive processing was assessed using cued retrospective reporting, whereas comprehension and transfer tests measured the quality of the constructed representation. Within the framework of Cognitive Load Theory, visual cues highlighting the subsystems of the heart were hypothesized to guide attention, reduce visual search and extraneous cognitive load, and enhance learning. As predicted, learners looked more often and longer at cued parts. However, we found no effects of cueing on visual search and cognitive load. With respect to cognitive processing, performance differences were found on the number of statements in the learners’ verbal reports. These findings suggest that visual cueing can guide attention in an animation, but other factors are also important in determining the effectiveness of visual cues on learning.  相似文献

ABSTRACT

In classroom, scientific contents are increasingly communicated through visual forms of representations. Students’ learning outcomes rely on their ability to read and understand pictorial information. Understanding pictorial information in biology requires cognitive effort and can be challenging to students. Yet evidence-based knowledge about students’ visual reading strategies during the process of understanding pictorial information is pending. Therefore, 42 students at the age of 14–15 were asked to think aloud while trying to understand visual representations of the blood circulatory system and the patellar reflex. A category system was developed differentiating 16 categories of cognitive activities. A Principal Component Analysis revealed two underlying patterns of activities that can be interpreted as visual reading strategies: 1. Inferences predominated by using a problem-solving schema; 2. Inferences predominated by recall of prior content knowledge. Each pattern consists of a specific set of cognitive activities that reflect selection, organisation and integration of pictorial information as well as different levels of expertise. The results give detailed insights into cognitive activities of students who were required to understand the pictorial information of complex organ systems. They provide an evidence-based foundation to derive instructional aids that can promote students pictorial-information-based learning on different levels of expertise.  相似文献

随着人工智能时代的来临,编程教育日益受到重视。学生在编程过程中的行为,实质上反映了其对利用计算工具解决问题的认知水平,也映射出其计算思维的发展过程,挖掘三者间的隐含关系有助于通过优化编程任务设计改善对学生计算思维的培养。基于认知目标分类和计算思维三维框架构建映射关系,以Scratch可视化编程任务作为研究案例,采用编程操作视频分析与学生访谈相结合的方法,从编程行为表征的视角对认知水平与计算思维间的隐含关系进行挖掘后发现:一方面,认知水平与编程行为之间存在密切关系,知道与理解是编程行为的基础性认知,应用与分析是编程行为的核心,评价推动学生对编程行为的反思,而创造可激发编程行为产生新的作品。另一方面,在编程活动中,学生的认知水平与计算思维的发展彼此关联且相互促进,编程行为中的低阶认知目标的达成是形成计算观念的基础,编程实践引发的高阶思维认知需求可促进学生对计算思维的领悟。因此,应当遵循认知水平与计算思维的发展规律,有针对性地将面向各类认知目标的编程任务嵌入到教学设计中,方可有效实现利用编程教育对学生计算思维的培养。  相似文献

The aim of this study was to examine whether behavioral style and cognitive performance predict cognitive development in ELBW children. The children were assessed at age 2 (40 girls, 41 boys) with the Bayley Scales of Infant Development. At age 4 they were assessed with the WPPSI-R, and with the word fluency, visual attention and recognition of incomplete figures subsets of the Finnish Neuropsychological Investigation for Children (NEPSY-R; Korkman et al. 1997). The results indicated that there was stability in cognitive performance from 2 to 4 years of age. Along with cognitive performance, behavioral style, especially orientation-engagement at age 2, was an important predictor of subsequent cognitive performance (WPPSI-R). Significant gender differences were also found. For boys, orientation-engagement factor at time one was the best predictor of subsequent nonverbal cognitive performance, arithmetical abilities and word fluency at time two. In contrast, girls’ cognitive performance measured at the 2-year assessment was the most powerful predictor of nonverbal performance and word fluency at 4 years. As a whole, it seems that behavioral factors merit more consideration in understanding cognitive development than has been thought before.  相似文献

Although much is known about adults’ ability to orient by means of cognitive maps (mental representations of the environment), it is less clear when this important ability emerges in development. In the present study, 97 seven- to 10-year-olds and 26 adults played a video game designed to investigate the ability to orient using cognitive maps. The game required participants to reach target locations as quickly as possible, necessitating the identification and use of novel shortcuts. Seven- and 8-year-olds were less effective than older children and adults in using shortcuts. These findings provide clear evidence of a distinct developmental change around 9 years of age when children begin to proficiently orient and navigate using cognitive maps.  相似文献

信息时代对人的要求在很大程度上取决于个人对信息搜索、获取、吸收、传递和创造的能力。学生在网络信息时代应该充分利用网络中丰富的信息资源为语文学习服务,培养快读、快写、快思的语文素养,以适应社会发展的需求。网络信息所显示的快捷、新鲜、繁多、不确定等特点,要求中学语文教师在语文教学中能够帮助学生利用网络有效地筛选并获取信息资源,实现阅读和写作方式的变革和发展。笔者在课堂教学和语文活动课中,尝试利用网络有意识地培养学生搜索和截获语言信息的能力。在网络时代,应用建构主义学习模式,采用探究性学习的形式能够有效地提高学生获取并运用语言信息的能力。  相似文献

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by cognitive deficits associated with attention. Prior studies have revealed the potential impact of ADHD on basic perception and cognitive ability in patients with ADHD. In this study, bilateral posterior P1 and N1 were measured in 122 Chinese children aged 7–12 years (64 with ADHD) to investigate the developmental characteristics of early perception during visual processing in school-age children with ADHD. For children with ADHD, a larger P1 activity with an atypical developmental pattern was evoked and observed for the visual search performance. These findings offer new insights into the mechanisms of cognitive developmental deficits and intervention techniques in children with ADHD.  相似文献

Advances in our knowledge of the structure of working memory suggest that under some circumstances, effectively more processing capacity is available to learners if instructional materials use multiple information modes (e.g. auditory and visual) instead of equivalent single mode formats. This paper examined this modality effect from a cognitive load perspective in three experiments using geometry instruction. In accordance with cognitive load theory, it was predicted that the additional processing capacity provided in an audio/visual format would only enhance learning if mental resources were not devoted to extensive visual based search in order to coordinate auditory and visual information. Using two different areas of geometry, Experiments 1 and 2 found that if visual search was clearly high, then audio‐visual instruction was only beneficial if visual indicators in the form of electronic flashing were incorporated into the instructional format. Under high search conditions, a standard audio/visual format without the aid of flashing proved no better than visual only instruction. Experiment 3 attempted to clarify earlier results by using instructional materials trivially low in visual search. Data indicated that a standard, audio‐visual format resulted in superior learning to a visual only format. There was no beneficial effect of electronic flashing in Experiment 3, suggesting that visual indicators were not necessary in areas of low visual search. It was concluded that cognitive load as determined by visual search established the effectiveness of visual indicators.  相似文献
