unconditioned stimulus

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。

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。

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

找出在非条件刺激不存在的情况下，能够使你感到恐惧的东西。

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。

What 's the unconditioned stimulus ?

什么是无条件刺激？

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。

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。

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。

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。

Fear conditioning reflex is a form of defense responses that subjects come to express to conditioned stimulus ( CS ) that are paired with unconditioned stimulus ( US ) .

恐惧条件反射是条件性刺激和非条件性刺激联系在一起时，机体对条件性刺激产生的一种防御性反应。

The imaging technique showed that some neurons were activated by the saccharine , or the conditioned stimulus , and others were activated by the lithium chloride or the unconditioned stimulus .

这种显像技术显示一些神经元能够被给予糖水或是条件刺激激活，而另一些神经元能够被注射氯化锂或非条件刺激物激活。

Well , when Pavlov , for instance , started before conditioning there was simply an unconditioned stimulus , the food in the mouth , and an unconditioned response , saliva .

比如，在条件作用形成之前，只是简单的存在着无条件刺激，即食物，以及无条件反应，即唾液。

It predicts that the best timing is when the conditioned stimulus , which is the signal , comes before the unconditioned stimulus , which is what you have to prepare for .

它预测，最佳的时机，莫过于作为信号的条件刺激，出现在需要你做准备的，非条件刺激之前。

A type of learning in which a conditioned stimulus is paired with an unconditioned stimulus to elicit a reflex response or respondent behaviour-Also referred to as Pavlovian Conditioning .

与中性刺激多次结合有效刺激而使有机体形成的条件反应。即是一种新的刺激引起已存在的反射反应。一种自动化的、非习得性的反应。
