概括
幼儿园儿童的大脑活动在阅读书籍和屏幕时间之间存在差异. 阅读书籍激活了右顶结 (TPJ),与屏幕时间不同,这表明对语言发育有不同的影响.
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
- 儿科语言发展指南
背景情况:
- 以前的研究表明,阅读书籍和屏幕时间对儿童发育有不同的影响.
- 有限的研究直接比较了幼儿在这些活动期间的大脑功能.
研究的目的:
- 为了调查学龄前儿童在阅读书本和屏幕时间期间大脑活动中的神经生物学差异.
- 探索大脑横向化模式如何在这两种常见的童年活动之间有所不同.
主要方法:
- 利用功能近红外光谱 (fNIRS) 来测量28名典型发育儿童 (36-72个月) 的大脑反应.
- 在实时阅读书籍的条件下与涉及数字媒体的屏幕时间条件下比较大脑激活.
- 分析了关键感兴趣区域的活动:下/中额头 (IMFG),上/中 (SMTG) 和顶结 (TPJ).
主要成果:

01:14Brain Imaging
Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).

01:27Language and Cognition
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.
