概括
媒体的节奏不会影响孩子的认知发展. 然而,观看奇幻媒体会在观看后立即对儿童的注意力和执行功能产生负面影响.
科学领域:
- 儿童发展
- 认知心理学
- 媒体研究
背景情况:
- 人们担心屏幕媒体对儿童认知发展的影响.
- 快节奏和奇幻的媒体内容被认为会耗尽认知资源,影响注意力和执行功能 (EF).
- 之前的经验测试对媒体节奏和幻想的短期影响产生了不同的结果.
研究的目的:
- 对媒体节奏和幻想对儿童注意力和EF的影响进行元分析综合.
- 在观看后立即调查媒体曝光的短期影响.
- 探索可能影响这些影响的缓解因素.
主要方法:
- 对19项研究 (141个效果大小,1431名年龄在1.5至10岁的儿童) 的分析综合.
- 对于媒体幻想的16项研究 (121个效果大小,1297名年龄在1.5-6岁的儿童) 的分析综合.
- 对认知结果的分析,包括注意力,认知灵活性,高阶EF,抑制控制和工作记忆.
主要成果:
- 中等速度对儿童的认知没有显著影响 (d = - 0. 123, p = 0. 23).
- 媒体幻想有负面影响,儿童在观看幻想内容后的注意力和 EF 任务表现较差 (d = -0.244,p = 0.02).
- 对于节奏和幻想的显著异质性表明了复杂的缓和条件.
结论:
- 媒体的速度并不总是影响儿童的短期认知表现.
- 奇幻的媒体内容会对儿童的注意力和执行功能产生直接的负面影响.
- 研究的特定认知方面显著影响了媒体曝光的短期影响,突出显示了屏幕媒体在儿童发展中的复杂作用.

Attention-Deficit/Hyperactivity Disorder
289
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

Information Processing Approach
152
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...
