美国有研究显示,3岁以下的儿童不宜观看电视。电视高密度的视频和音频输出,可能损伤正在迅速发育的大脑,并进一步影响将来的学习能力。研究发现,如果他们在3岁以前,平均每天观看1小时电视,则在数学成绩、阅读辨识能力和阅读理解能力上都表现较差,显示过早看电视可能对他们的发展有负面影 Studies in the United States have shown that children under 3 years old should not watch TV. Television’s high-density video and audio output can damage the rapidly developing brain and further influence future learning. The study found that if they watched 1 hour of television a day before the age of 3, they performed poorly in math scores, reading comprehension and reading comprehension, indicating that premature television viewing may have a negative impact on their development
