What's the difference between 行動 and 動作?


I did some looking around and I found that 動作 is the behavior of machines and
行動 is the behavior of people, but that can't be it since on my textbook I find
the following sentence:

> 彼女は話し方が丁寧なのに対して動作が丁寧でない。

Also saw some people saying that 行動 is the movement of people and 動作 is
movement of the body, but I'm kinda confused about that.

Can someone explain the difference between these two words?




行動 is more like behavior or activity. It's a relatively complex movement of a
lifeform that may take a long time and usually has a certain purpose. Examples
of 行動 include "going shopping", "preparing and eating dinner", "playing
baseball" and "attending a meeting". It's typically used for human activities,
but you can also safely say アリの行動 or ロボットの行動 if it appears to be a purposeful
sophisticated movement (or sequence of movements).

動作 refers to more primitive, mechanical movements. It can be involuntary.
Examples of 動作 include "walking", "clapping hands", "hitting a ball with a
bat" and "breathing". Operation of a machine or software is also called 動作.
