[主观题]

专家在测试时发现,缺觉的学生虽然可以回答难题,却记不住简单的单词。同时,睡眠缺失对孩子的学习记

忆可能造成不可逆的损害。研究发现睡眠不足时,大脑部分功能区出现了不同程度的抑制状态,这使得学生在进行一些简单学习时常常出现失误。而面对难题时,由于通过额外激活与记忆、注意密切相关的前额叶皮质区域来补偿缺失的功能,学生答题的正确率以及反应时间并未受到显著影响。专家认为,虽然没有足够证据证明睡眠不足会直接影响智商,但有证据可以证明缺觉学生的注意力以及记忆力都会受到影晌。

缺觉的孩子回答难题和简单题目表现出差异的根本原因是()。

A. 进化论和进步论的根本区别

B. 反进化论的观点缺乏事实根据

C. 进化论很难预测物种的进化趋势

D. 应科学认识进化论的含义和作用
