概括
患有注意力缺陷多动症 (ADHD) 的儿童表现出时间感知障碍,显著与选择性注意力和运动反应速度有关,而不是工作记忆. 这些发现支持ADHD的动态参与理论 (DAT).
科学领域:
- 神经科学是一个神经科学.
- 认知心理学 认知心理学
背景情况:
- 注意缺陷多动症 (ADHD) 与时间感知方面的困难有关.
- 现有的理论,如标量期望理论 (SET) 和动态出席理论 (DAT),为这些缺陷提供了不同的解释.
- SET强调了受到工作记忆影响的节拍器-计数器系统,而DAT强调了注意力的作用.
研究的目的:
- 研究注意力,工作记忆和运动反应对ADHD儿童时间感知的影响.
- 为了比较患有ADHD的儿童与典型发育的对照者之间的这些认知机制.
主要方法:
- 94名7至12岁的儿童 (47名患有多动症,47名对照儿童) 参与了这项研究.
- 计算机化任务评估了时间感知,持续的注意力,选择性注意力/反应时间和工作记忆.
- 使用独立t测试和线性回归分析的数据.
主要成果:
- 与对照组相比,ADHD儿童的时间感知准确性明显较差.
- 在ADHD组中,选择性注意力和反应时间预测了时间感知缺陷.
- 年龄是对照组不准确性的唯一预测因素.
结论:
- 在ADHD中,时间感知缺陷主要是由选择性注意力和运动反应速度驱动的.
- 这些发现支持动态参与理论 (DAT),强调注意力和反应时间.
- 针对注意力和运动反应的干预措施可以改善ADHD儿童的时间准确性.

Attention-Deficit/Hyperactivity Disorder
792
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....

Working Memory
813
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

Information Processing Approach
522
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...
