简述经典性条件反射的基本内容。
正确答案及解析
正确答案
解析
【要点】巴甫洛夫在研究消化现象时，观察了狗的唾液分泌，即对食物的一种反应特征。
他的实验方法是，把食物显示给狗，并测量唾液分泌。在这个过程中，他发现随同食 物反复给一个中性刺激，即一个并不自动引起唾液分泌的刺激，如铃响，这只狗就会逐渐 “学会”在只有铃响但没有食物的情况下分泌唾液。一个原有中性的刺激与一个原来就能引起某种反应的刺激相结合，从而使动物学会对那个中性刺激做出反应，这就是经典性的条件反射的基本内容。

For the road warrior
The new BlackBerry Storm is something likethe equivalent (等同物) of a mullet--a business up front, party in the back.

For the Luddite (反对技术进步的人)
For those who can′t handle buttons and newfeatures, there is the Samsung Jitterbug Dial. Some people are Luddites whojust want a few large buttons to make calls. That′s it, just calls. That makesit even easier to use an iPhone.
