概括
患有发育协调障碍 (DCD) 的儿童会自动调整动作以符合节奏线索,甚至在潜意识中. 计划的调整只有在意识到大变化时才会发生,而DCD会影响神经连接.
科学领域:
- 神经科学是一个神经科学.
- 发展心理学 发展心理学
- 审计 - 运动集成的整合.
背景情况:
- 患有发育协调障碍 (DCD) 的儿童在感知-行动合方面扎,特别是在需要预测时间的任务中.
- 了解自动与计划的运动调整以及意识与潜意识的处理对于DCD研究至关重要.
- 听觉-运动同步和节奏伴奏在DCD中的作用需要进一步研究.
研究的目的:
- 调查意识如何影响DDC和没有DDC的儿童对节律扰乱的听觉运动调整.
- 为了确定儿童的运动同步是自动的还是计划的,以及调整是有意识的还是潜意识的.
- 通过使用脑电图 (EEG) 检查这些调整策略的神经基础.
主要方法:
- 32名儿童 (7-11岁),包括患有DCD和典型发育 (TD) 同龄人 (有/没有音乐培训) 的儿童,参与了这项活动.
- 评估了参与者对小型和大型节律扰乱的听觉运动调整.
- 脑电图 (EEG) 用于在调整过程中分析功能连接模式.
主要成果:
- 所有孩子都自动调整到小,有意识地无法检测到的扰动,使用预测时间.
- 计划的调整,转向反应性策略,只有在有意识地检测出大扰动 (Δ 20%) 时才发生.
- 患有DCD的儿童在计划调整期间表现出降低的半球间连接性和跨条件的类似神经模式,但受益于节奏的卷入.
结论:
- 儿童对听觉节奏的运动调整包括自动和计划的策略,受意识意识和扰乱大小的影响.
- 在计划的调整过程中,DCD与神经连接的改变有关,但节奏性引进仍然是有益的.
- 研究结果支持基于听觉/节奏的干预措施对患有DCD的儿童的治疗潜力,音乐训练可以增强听觉感知时间和神经连贯性.

States of Arousal During Infancy
States of arousal describe an infant’s physiological and behavioral condition during sleep, wakefulness, and activity. These states are regulated by the circadian rhythm, an internal biological clock that organizes daily patterns of rest and alertness. During infancy, arousal is commonly classified into five states: regular sleep, irregular sleep, drowsiness, alert inactivity, and waking activity.Regular and Irregular SleepDuring regular sleep, an infant’s eyes remain closed, breathing is slow...
Hearing During Infancy and Toddlerhood
Hearing begins developing before birth. Fetuses respond to sounds in the womb through changes in brain activity, heart rate, and body movements, showing sensitivity to auditory stimulation. After birth, hearing continues to develop rapidly, supporting language learning and environmental awareness.Auditory Acuity and Sound LocalizationAuditory acuity refers to the ability to detect sounds. Newborns are especially responsive to human voices and can detect many speech sounds, although their...
Development of Head Control During Infancy
The control of head posture and movement is an important early milestone in motor development. During the first four months of life, infants gradually learn to stabilize and move their heads against gravity. Head control depends on the gradual strengthening and coordination of the neck, shoulder, and upper trunk muscles.Early Head MovementsAt birth, infants have limited control over their heads because their neck muscles are still weak. While lying on their backs, newborns can usually turn...
Hand Control During Infancy and Toddlerhood
Hand movements during infancy and toddlerhood develop from broad, relatively uncontrolled actions into increasingly precise fine motor skills. This progression depends on nervous system maturation, improved muscle control, and repeated interaction with objects. Early reflexive movements gradually give way to intentional reaching, grasping, object manipulation, and tool use.Early Grasping SkillsNewborns show a strong palmar grasp reflex, automatically closing their fingers when the palm is...
Locomotion During Infancy and Toddlerhood
Children develop a wide range of gross motor skills during the first three years, as increasing muscle strength, balance, coordination, and nervous system maturation allow greater control over body movements. Development generally progresses from basic postural control to independent movement and later to activities such as jumping, climbing, and pedaling.Motor Development During the First YearMost infants begin rolling during the first several months, although the timing and direction can vary.
Motor Skills Development During Early Childhood
Early childhood is a period of rapid motor development in which children refine gross and fine motor skills. These abilities increase independence and support social interaction, play, and learning.Gross Motor SkillsGross motor skills involve coordinated movements of large muscle groups, including running, jumping, and climbing. By about 2.5 years, most children can jump with both feet. Hopping, which requires greater balance and strength, usually emerges around age 4.Stair climbing also...
