We start with an empathy test, because we thought at the beginning that excombatants will have a low level of empathy.

我们从同理心测试开始，因为一开始我们认为前战斗人员的同理心水平较低。

But they had participants take an empathy test, and people who were more empathetic tended to learn almost as quickly when they were playing for someone else — the prosocial behavior.

但是他们让参与者进行了同理心测试，而同理心更强的人在为别人演奏时往往学得几乎一样快——亲社会行为。
