概括

患有发育协调障碍 (DCD) 的儿童在决策任务中显示出视觉和正面区域的大脑活动增加,这表明需要更多的注意. 这可能是DCD视觉运动处理缺陷造成的.

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
儿科儿科儿科

背景情况:

发育协调障碍 (DCD) 是一种影响运动技能的神经发育状况.
了解DDC的神经基础对于有针对性的干预至关重要.

研究的目的:

在虚拟决策任务期间,调查患有和没有DCD的儿童的大脑激活模式.
为了比较患有DCD的儿童和神经类型对照者的神经活动和任务性能.

主要方法:

功能磁共振成像 (fMRI) 用于扫描22名患有DCD的儿童和22名神经类型对照.
参与者完成了一项虚拟任务,涉及方向选择和避免机动.
研究人员分析了神经活动和行为反应,并在两组之间进行了比较.

主要成果:

患有DCD的儿童在避开任务期间表现出视觉皮层和右中额头环的高度激活.
在人-方向任务期间,没有观察到神经激活的显著差异.
患有DCD的儿童在人方向任务中表现出较低的准确性,尽管反应时间相似.

结论:

与神经型儿童相比,患有DCD的儿童在决策任务中需要更多的注意力资源.
在DCD中增加的认知努力可能与潜在的视觉运动处理缺陷有关.

Decision Making

Decision Making

Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

Attention-Deficit/Hyperactivity Disorder

Attention-Deficit/Hyperactivity Disorder

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....
