What is scientists' finding about dreaming?
A. It involves disconnected, weird images.
B. It resembles fragments of science fiction.
C. Dreaming about a learned task better its performance.
D. Dreaming about things being learned disturbs one's sleep.
题目解答
答案
C. Dreaming about a learned task better its performance.
解析
本题考查对科学家关于梦境研究的核心发现的理解。解题关键在于区分选项中描述梦境表象与科学研究结论的差异。正确选项需体现梦境对学习或记忆的积极影响，而非仅描述梦境的零散或科幻特征。需注意排除干扰项，如“干扰睡眠”的错误表述。
选项分析：
- A) It involves disconnected, weird images
仅描述梦境的零散、奇异特性，未涉及科学研究的核心结论，排除。 - B) It resembles fragments of science fiction
类比科幻片段，仍是表象描述，未体现研究重点，排除。 - C) Dreaming about a learned task betters its performance
正确选项。研究表明，梦到已学任务（如迷宫实验）能巩固记忆，提升实际表现。 - D) Dreaming about things being learned disturbs one's sleep
错误。科学发现表明梦境有助于记忆巩固，而非干扰睡眠。
关键结论：梦境内容与学习任务相关时，可促进任务表现，如实验中梦到迷宫的被试表现更优。
