概括
患有严重发育协调障碍 (s-DCD) 的儿童在抑制性任务中表现出持续的困难,与中度发育协调障碍或典型发育的同龄人不同. 在DDC群体中,认知运动技能随着年龄的增长而得到改善.
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
- 发动机控制器的控制器
背景情况:
- 发育协调障碍 (DCD) 影响儿童的运动技能.
- 抑制性控制对于复杂的运动任务至关重要.
- 了解DDC亚型的认知运动性能是必不可少的.
研究的目的:
- 调查与典型发育儿童 (TDC) 相比,患有严重 (s-DCD) 和中度 (m-DCD) DCD的儿童对双跳到达任务 (DJRT) 性能的抑制负载效应.
- 在一年内检查DJRT和反跳到达任务 (AJRT) 性能的纵向变化.
- 评估DCD亚型内的运动任务执行的年龄相关差异.
主要方法:
- 长度研究包括20个s-DCD,43个m-DCD和192个TDC儿童 (年龄在6-12岁).
- 在1年的随访期间进行了两次测试.
- 使用触摸屏接口测量标准DJRT和AJRT的性能.
- 运动时间差 (MTdiff) 计算在跳跃/反跳跃和不跳跃试验之间.
主要成果:
- 没有对标准DJRT性能产生显著的电机组影响.
- 年龄较大的孩子 (9-12岁) 在DJRT中更快地调整跳跃目标.
- 与m-DCD和TDC组相比,s-DCD组表现出明显较慢的AJRT性能和较大的MTdiff得分.
- 这些差异在s-DCD组中无论年龄如何都存在.
结论:
- 认知运动合,特别是抑制控制,在患有DCD的儿童中随着年龄的增长而改善.
- 患有严重DCD的儿童在需要抑制控制的任务中表现出持续的,显著的困难,即使年龄大了.
- 这些发现凸显了S-DCD个体在汽车规划和执行方面所面临的独特挑战.

Information Processing Approach
497
The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...

Oppositional Defiant Disorder
591
A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

Attention-Deficit/Hyperactivity Disorder
722
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....
