unconditioned stimulus

When the conditioned stimulus and the unconditioned stimulus are brought together over and over and over again, pretty soon the conditioned stimulus gives rise to the response.

当条件刺激与非条件刺激，同时且多次反复出现，条件刺激很快也能引起条件反应。

Well, you show the thing that would cause you to have the fear without the unconditioned stimulus.

First, there's difference in the associative network. The association of similarity, started by the same external stimulus to the same sense of different nations, may sometimes differ under the influence of different cultures though the synaesthetic physiological phenomenon belongs to the unconditioned reflex.

首先是联想机制差异，通感生理现象虽属与生俱来的非条件反射，但不同民族的同一感官对同一外部刺激所引起的相似联想并非处处一致，往往受制于不同文化。

A reinforced trial is when the conditioned stimulus and the unconditioned stimulus go together.

强化尝试是指条件刺激，与无条件刺激同时出现的时候。

When Pavlov put food powder in the dog's mouth and saliva was generated, that's an unconditioned stimulus giving rise to an unconditioned response.

巴甫洛夫给狗喂食，狗会分泌唾液，这就是无条件刺激引起了无条件反应。

The conditioned response is a preparation for the unconditioned stimulus.

条件反应是对无条件刺激的一种准备。

Now the pain of a bite, being bit, and then the pain and fear of that is an unconditioned stimulus, unconditioned response.

咬伤所带来的疼痛感，和有此所带来的痛苦与恐惧，就是无条件刺激和无条件反应。

Bernstein and her colleagues also proposed a model that associative learning takes place when a conditioned stimulus is followed by an unconditioned stimulus, triggering convergent neurons.

伯恩斯坦博士和她的同事还提出一种模型，即当给予非条件刺激物后给予条件刺激，联想性学习就会发生，即触发了会聚神经元。

What's the unconditioned stimulus?

什么是无条件刺激？

So, the idea here is, repeated pairings of the unconditioned stimulus and the conditioned stimulus will give rise to the response.

这里的意思是说，无条件刺激与条件刺激的反复匹配，会引起条件反应。
