练习律(Law of exercise)是指联结的强度决定于使用联结的频次，即S-R联结受到练习和使用的频次越多，则联结得越强; 反之，则变得越弱。在桑代克后来的著作中，他修改了这一规律，因为，他发现没有奖励的练习是无效的。联结只有通过有奖励的练习才能得以增强。

比方说，如果你是爵士乐爱好者，你就要练习在一段音乐中只听中高音萨克斯管，其他乐器声和歌唱声一律不听。
For example, if you're a jazz lover, you might practice by turning on some music and listening only to the alto saxophone, blocking out all the other instruments or vocals.
