And so classical conditioning was discovered.

于是经典条件反射理论诞生了。

Let's talk about classical conditioning first.

我们先来说说经典条件反射。

Most of the time, it's through classical conditioning.

大多数时候都是通过经典条件反射。

Some phobias, which are extreme or irrational fears, can be caused by classical conditioning, including a fear of the dark.

有些恐惧症是极端或非理性的恐惧，可以由经典条件反射引起，包括对黑暗的恐惧。

That's the most famous example of classical conditioning.

这是经典条件作用最著名的例子。

Two of the main types of learning are called classical conditioning and operant, or instrumental, conditioning.

学习的两大主要类型为经典条件性反射和操作性条件反射。

He developed the theory of classical conditioning by making a distinction between two sorts of conditioning, two sorts of stimulus response relationships.

他通过区分两种条件作用，两种刺激反应关系，提出了经典条件作用理论。

And so classical conditioning should be the strongest when these two are simultaneous and the response to one is the same as the response to the other.

当无条件刺激与条件刺激同时出现时，经典条件作用的效果最强，两种刺激所引起的反应是相同的。
