The serial reaction time task (SRTT) is commonly used to study motor learning and memory. The task is traditionally administered in a lab setting with participants responding via button box or keyboard to targets on a screen. By comparing response times of sequential versus random trials and accuracy across sequential trials, different forms of learning can be studied. The present study utilized an online version of the SRTT to study the effects of instructions on learning. Participants were randomly assigned to an explicit learning condition (with instructions to learn the visual sequence and associated tone) or an implicit learning condition (without instructions). Stimuli in both learning conditions were presented in two phases: auditory and visual (training phase), followed by auditory only (testing phase). Results indicated that learning occurred in both training and testing phases, as shown by a significant decrease in response times. There was no significant main effect of learning condition (explicit or implicit) on sequence learning. This suggests that providing explicit instructions does not seem to influence sequence learning in the SRTT learning paradigm. Future online studies utilizing the SRTT should explore varying task instructions in a parametric manner to better understand cognitive processes that underlie sequence learning.
连续反应时间任务(SRTT)是研究运动学习和记忆的常用方法。这项任务传统上是在实验室环境中进行的,参与者通过按钮框或键盘对屏幕上的目标做出反应。通过比较顺序试验与随机试验的反应时间和顺序试验的准确性,可以研究不同形式的学习。本研究利用SRTT的在线版本来研究指导对学习的影响。参与者被随机分配到显性学习条件(有指示学习视觉序列和相关音调)或内隐学习条件(没有指示)。两种学习条件下的刺激均分为两个阶段:听觉和视觉(训练阶段),然后是听觉(测试阶段)。结果表明,学习发生在训练和测试阶段,反应时间显著减少。学习条件(内隐和外显)对序列学习没有显著的主效应。这表明,在SRTT学习范式中,提供明确的指令似乎并不影响顺序学习。未来利用SRTT的在线研究应该以参数化的方式探索不同的任务指令,以更好地理解序列学习背后的认知过程。

Background: Balancing performance can be affected by regular and high-level athletic training, which has not been fully explored in synchronized ice skaters. This study aimed to analyze the dynamic balancing performance by assessing the principal and compensatory movements performed during the sudden provocation tests and evaluating the parameters that characterize the platform’s motion. Method: Twelve young female synchronized ice skaters and 12 female age-matched controls participated. Sudden provocation tests were completed three times in bipedal stance and in single-leg stances, and sport-specific fatigue session was inserted between the repetitions. Results: Significantly more time was necessary to recover balance for both groups after the fatiguing sessions (p < .05). Interestingly, skaters performed less effectively in the simplest condition (bipedal stance) than the control group (p < .05). The principal component analysis showed that the first principal movement was the same for both groups. The skater group used the upper body and arms more often to compensate, while the control group’s recovery strategy consisted mainly of abduction of the elevated leg. The damping ratio and the relative variance of the first principal movement showed a negative correlation (p < .05), suggesting that those with superior balancing effectiveness recruited more compensatory movements.
背景:平衡表现会受到定期和高水平运动训练的影响,这在花样滑冰运动员中尚未得到充分的探讨。本研究旨在通过评估在突然激发试验中进行的主运动和补偿运动以及评估表征平台运动的参数来分析动平衡性能。方法:12名年轻女子花样滑冰运动员和12名年龄匹配的女性对照组。在两足站姿和单腿站姿下完成三次突然激发试验,并在重复之间插入运动特定疲劳训练。结果:两组在疲劳训练后恢复平衡所需的时间明显增加(p < 0.05)。有趣的是,滑冰运动员在最简单的条件下(两足站立)的表现不如对照组(p < 0.05)。主成分分析表明,两组的第一个主运动是相同的。滑冰组更多地使用上半身和手臂来补偿,而对照组的恢复策略主要是抬高腿的外展。阻尼比与第一主动作的相对方差呈负相关(p < 0.05),表明平衡能力强的人会招募更多的代偿动作。

Background: The purpose of this study was to examine the effect of the follow-through on thrown ball velocity, potentially justifying inclusion of the follow-through in Roberton’s five critical components. Method: Seventy-eight University students participated in the overarm, dominant hand, throwing task, which involved throwing a standard tennis ball with maximum force three times. Each throw was filmed by two cameras placed behind and to the open side of the thrower to assess the throwing technique. The velocity of the throws was recorded with a radar gun. Results: Results indicated that, after accounting for the effects of gender, age, and throwing experience, there was a significant effect of follow-through level on throw velocity. Analysis of covariance also revealed a significant gender effect, with males throwing significantly faster than females. Results indicated the follow-through had the second largest impact on thrown ball velocity of all six components. Discussion: These findings provide preliminary support that the follow-through should be added to Roberton’s developmental levels. The inclusion of the follow-through component could assist teachers and coaches to facilitate learner and athlete development and could also improve the accuracy of throwing development assessment.
背景:本研究的目的是为了检验后续动作对投球速度的影响,潜在地证明将后续动作纳入罗伯顿的五个关键组成部分。方法:78名大学生参加了一项用最大力量投掷一个标准网球三次的伸臂、优势手投掷任务。每次投掷都由放置在投掷者身后和开放侧的两台摄像机拍摄,以评估投掷技术。投掷的速度用雷达枪记录了下来。结果:结果表明,在考虑了性别、年龄和投掷经验的影响后,随动水平对投掷速度有显著影响。协方差分析也揭示了显著的性别效应,男性投掷明显快于女性。结果表明,在所有六个组成部分中,随动对抛球速度的影响都是第二大的。讨论:这些发现提供了初步的支持,跟进应该添加到罗伯顿的发展水平。加入跟进部分可以帮助教师和教练促进学习者和运动员的发展,也可以提高投掷发展评估的准确性。

Contextual interference is an established phenomenon in learning research; random practice schedules are associated with poorer performance, but superior learning, compared with blocked practice schedules. We present a secondary analysis of N = 84 healthy young adults, replicating the contextual interference effect in a time estimation task. We used the determinant of a correlation matrix to measure the amount of order in participant responses. We calculated this determinant in different phase spaces: trial space, the determinant of the previous five trials (lagged constant error 0–4); and target space, the determinant of the previous five trials of the same target. In trial space, there was no significant difference between groups (p = .98) and no Group × Lag interaction (p = .54), although there was an effect of Lag (p < .01). In target space, there were effects of Group (p = .02), Lag (p < .01), and a Group × Lag interaction (p = .03). Ultimately, randomly scheduled practice was associated with adaptive corrections but positive correlations between errors from trial to trial (e.g., overshoots followed by smaller overshoots). Blocked practice was associated with more adaptive corrections but uncorrelated responses. Our findings suggest that random practice leads to the retrieval and updating of the target from memory, facilitating long-term retention and transfer.
语境干扰是学习研究中的一种普遍现象;与固定的练习计划相比,随机的练习计划与较差的表现有关,但与更好的学习有关。我们对N = 84名健康年轻人进行了二次分析,在时间估计任务中复制了上下文干扰效应。我们使用相关矩阵的行列式来衡量参与者回答中的顺序量。我们在不同的相空间中计算这个行列式:试验空间,前五次试验的行列式(滞后常数误差0-4);目标空间,是同一目标前五次试验的行列式。在试验空间中,组间无显著差异(p = 0.98),组与组间无交互作用(p = 0.54),但有Lag的影响(p < 0.01)。在靶区,有组效应(p = 0.02)、Lag效应(p < 0.01)和组与Lag交互作用(p = 0.03)。最终,随机安排的练习与适应性修正有关,但与试验之间的误差呈正相关(例如,超调之后是较小的超调)。阻断练习与更多的适应性纠正相关,但与反应不相关。我们的研究结果表明,随机练习导致目标从记忆中检索和更新,促进长期保留和转移。

Can Infants Generalize Tool Use From Spoon to Rake at 18 Months? 18个月大的婴儿能从勺子学到耙子吗?

Infants start to use a spoon for self-feeding at the end of the first year of life, but usually do not use unfamiliar tools to solve problems before the age of 2 years. We investigated to what extent 18-month-old infants who are familiar with using a spoon for self-feeding are able to generalize this tool-use ability to retrieve a distant object. We tested 46 infants with different retrieval tasks, varying the tool (rake or spoon) and the target (toy or food). The tasks were presented in a priori descending order of difficulty: rake–toy condition, then either spoon–toy or rake–food, and finally spoon–food. Then, the same conditions were presented in reverse order to assess the transfer abilities from the easiest condition to the most difficult retrieval task. Spontaneously, 18-month-old infants performed the retrieval tasks better with the familiar tool, the easiest task being when the spoon was associated with food. Moreover, the transfer results show that being able to use a familiar tool in an unusual context seems necessary and sufficient for subsequent transfer to an unfamiliar tool in the unusual context, and that early and repetitive training of self-feeding with a spoon plays a positive role in later tool use.
婴儿在一岁结束时开始使用勺子进行自我喂养,但通常在2岁之前不会使用不熟悉的工具来解决问题。我们调查了18个月大的婴儿在多大程度上熟悉使用勺子进行自我喂养,能够推广这种工具使用能力来检索远处的物体。我们测试了46名婴儿不同的检索任务,不同的工具(耙子或勺子)和目标(玩具或食物)。这些任务是按照难度的先验递减顺序呈现的:首先是耙子玩具,然后是勺子玩具或耙子食物,最后是勺子食物。然后,将相同的条件以相反的顺序呈现,以评估从最简单的条件到最困难的检索任务的迁移能力。自发地,18个月大的婴儿用熟悉的工具更好地完成检索任务,最简单的任务是当勺子与食物联系在一起时。此外,迁移结果表明,能够在不寻常的环境中使用熟悉的工具对于随后在不寻常的环境中迁移到不熟悉的工具似乎是必要和充分的,并且早期和重复的用勺子自我喂食训练在后来的工具使用中起着积极的作用。

This study examines the associations of physical activity and gross motor skills in parent–child dyads. Parent–child dyads (N = 61, 84% mothers, children aged 8–11 years) participated in this study. Anthropometrics were self-reported through Qualtrics. Physical activity was assessed using accelerometers. Motor skills were measured through four skills: catch, kick, throw, and jump. These skills were assessed using process (i.e., performance criteria of the Test of Gross Motor Development-3) and product (i.e., catch percentage and jump distance) measures. A complete motor skill score was computed by standardizing both process and product scores and summing them. Correlation coefficients and ordinary least square regressions were computed to examine the associations of physical activity and motor skills. Parents’ and children’s moderate to vigorous physical activity were significantly associated (β = 0.30 ± 0.11; p = .008). Parents’ and children’s motor skills were significantly associated (β = 0.46 ± 0.18; p = .012). Understanding parent determinants can support effective interventions targeting children’s low physical activity levels and improving motor competence. Our results highlight the importance of parents’ physical activity and motor skills, which are significantly associated with those of their children. These parent factors may be a key consideration for effective family-based physical activity interventions.
本研究探讨了亲子二人组中体力活动与大动作技能的关系。亲子双元组(N = 61, 84%为母亲,儿童年龄8-11岁)参与本研究。人体测量是通过质量测试自我报告的。使用加速度计评估身体活动。运动技能是通过四项技能来衡量的:接球、踢腿、投掷和跳跃。这些技能是用过程(即大肌肉运动发展测试-3的表现标准)和产品(即接球百分比和跳跃距离)来评估的。通过标准化过程和产品分数并将其相加,计算出完整的运动技能分数。计算相关系数和普通最小二乘回归来检验体力活动和运动技能的关联。父母与孩子的中高强度体力活动显著相关(β = 0.30±0.11;p = .008)。父母与孩子的运动技能显著相关(β = 0.46±0.18;p = .012)。了解父母的决定因素可以支持针对儿童低体育活动水平和提高运动能力的有效干预。我们的研究结果强调了父母的体育活动和运动技能的重要性,这与他们的孩子有很大的关系。这些父母因素可能是有效的以家庭为基础的身体活动干预的关键考虑因素。

Objective: To determine which type of feedback (visual, verbal, or both combined) facilitates to a greater extent the learning of a specific skill (passing in volleyball). Methods: Three groups of students between 14 and 15 years of age belonging to the third year of Compulsory Secondary Education in a Spanish public high school (n = 58) were randomly assigned a type of feedback implemented in the part of the syllabus dedicated to volleyball. The students’ knowledge, motor performance, accuracy, and self-perception about the action were evaluated before and after the intervention and enjoyment afterwards. Results: All the groups obtained improvements in all the variables studied (p < .05); the verbal and visual feedback group was the one that obtained greater improvements, showing also a greater enjoyment than the visual feedback group. Conclusions: It has been found that the use of the combination of verbal and visual feedback is most recommended for learning a specific skill, such as passing in volleyball.
目的:确定哪种类型的反馈(视觉,口头,或两者结合)在更大程度上促进了特定技能的学习(排球中的传球)。方法:三组14至15岁的西班牙公立高中义务中等教育三年级学生(n = 58)被随机分配一种类型的反馈,实施在专门的排球教学大纲的一部分。评估干预前后学生对动作的认知、动作表现、准确性、自我知觉及干预后的享受程度。结果:各组在各项指标上均有改善(p < 0.05);口头和视觉反馈组比视觉反馈组获得了更大的改善,也表现出更大的享受。结论:研究发现,在学习一项特定技能时,最推荐使用语言和视觉反馈相结合的方法,比如在排球中传球。

The theory of reinvestment in experimental psychology suggested that automated performance could be degraded if attention was internally diverted to the process of skill execution. This study examined the role of attentional focus instructions on real-time conscious motor processing (i.e., reinvestment) during tandem walking. Thirty-six young adults (mean age = 20.94, SD = 1.43 years) participated; their electroencephalography T3–Fz coherence (i.e., real-time reinvestment) was measured during three walking conditions with different attentional focus instructions: external focus, internal focus, and control conditions. The results suggested that attentional focus instructions did not significantly affect real-time conscious motor processing during tandem walking in young adults, possibly due to the low level of motor task complexity of walking by young adults. The Movement-Specific Reinvestment Scale appears to be not sensitive enough to reflect the real-time reinvestment during gait-related movements in young adults.
实验心理学中的再投资理论表明,如果注意力内部转移到技能执行过程中,自动化性能可能会降低。本研究考察了注意力集中指令在双人步行过程中实时意识运动加工(即再投资)中的作用。36名年轻成人(平均年龄20.94岁,SD = 1.43岁)参与;在三种不同的注意焦点指示条件下:外部焦点、内部焦点和控制条件下,测量他们的脑电图T3-Fz相干性(即实时再投资)。结果表明,注意焦点指令对年轻人串联步行时的实时意识运动加工没有显著影响,这可能是由于年轻人步行的运动任务复杂性较低。动作特异性再投资量表似乎不够敏感,不足以反映年轻人在步态相关动作中的实时再投资。

The purpose of this study was to examine state-level early learning standards specific to physical development, including fundamental motor skills and gross motor development for preschool-aged children in the United States. All standards related to motor development and specific to children ages 3–5 years were extracted from publicly available online documents from all 50 states. Upon initial review, 961 standards were extracted from all documents. Through aggregation of similar skills and elimination of duplicates across states, 48 unique skills were identified. Frequencies and proportions of states that included each skill in their standards were calculated. Descriptive results indicate that none of the 48 skills were included as a standard across all 50 states. Only three skills, running, jumping, and throwing a ball overhand were a standard in over 75% of states. Most of the skills were standards in less than 50% of states. Trends from these data show that a wide range of motor skills are included within preschool physical development standards within the United States, with large variability among states. Considering this variability, and currently low levels of motor competence among young children, additional evaluation, and future creation of best practice preschool physical development standards are warranted.
本研究的目的是检查针对美国学龄前儿童身体发展的州一级早期学习标准,包括基本运动技能和大肌肉运动发展。所有与运动发展相关的标准以及3-5岁儿童的特定标准都是从所有50个州的公开在线文件中提取的。经初步审查,从所有文件中提取了961项标准。通过汇总各州的相似技能和消除重复技能,确定了48种独特的技能。计算了各州将每种技能纳入其标准的频率和比例。描述性结果表明,这48项技能中没有一项被纳入所有50个州的标准。在超过75%的州,只有三项技术是标准的,跑步、跳跃和过手投球。大多数技能在不到50%的州达到了标准。这些数据的趋势表明,美国学龄前儿童的身体发展标准中包含了广泛的运动技能,各州之间存在很大差异。考虑到这种可变性,以及目前幼儿运动能力水平较低,有必要进行额外的评估,并在未来制定学前身体发展标准的最佳实践。
