压力测试下的思维定势

上逻辑与思维方法课时，徐慈华老师说到，人在压力测试下容易产生思维定势，不易变通，并且举了一个例子。 他让一个同学起来回答一组问题，每道题目的思考时间只有10秒。题目如下：

假设有三种不同的容器ABC，每种容器的容量固定，为了量出一定要求容量的水，该如何使用这三个容器？

三种情况逐一问答。第一种情况中容器A为21ml，容器B为127ml，容器C为3ml，为了量出100ml，在10秒的思考时间内容易想到：

对于第二种情况，迫于时间压力，大部人分会先试一试第一种情况的方法，毕竟已经有成功的经验。通过试算，有：

非常好，得到了两次正确的反馈，对于第三题的解决已经是胸有成竹了，几乎可以脱口而出：

三道题在时间限制下顺利答完，这个过程中前一道题正确的解题方法对下一道题的心理暗示起到了很大的作用，但是也会带来思维定势的负面影响。 例如在第三问中，实际上只需要

这个解法显然更优于刚刚的方法。如果把三个问题的顺序进行调换，一开始就面对第三问，那答案就会很不一样。 因此，当我们处于压力测试时，固定的思维模式能节省不少时间，但若有能力静下心来抛开思维定势，往往会得到意想不到的收获。

Coursera musicianship & songwriting assignments

Musicianship Assignment 1

Study on relationship between chords, melodies and key the song is in. With the knowledge of harmony you can tell what the pleasing combination of musical sounds is. You will also understand the way in which musical chords are constructed.
