| 2. | In contrast , most laboratory experiments that investigate how animals learn are aimed at revealing the subject ' s ability for individual learning
相对地，在实验室里，大多数研究动物如何学习的实验，目标都在找出实验对象自行学习的能力。 |
| 3. | After several repetitions , the animals learned to blink after hearing the noise in anticipation of the puff of air , and they timed their blinks to avoid it
几次重复之后，老鼠学会在听到这个声音后眨眼睛，它们预计到会有一阵气，控制好时间眨眼睛以避开这阵气体。 |
| 4. | The biggest hope is that we will then be able to find out how to operate those functions and improve the speed at which animals learn , or help them remember for longer periods of time
最大的希望是因此而发现如何来控制这些功能，并且提高动物学习的速度，或者帮助动物能长时间地记住事情。 |
| 5. | It is plain that , while animals learn about things by their senses as we do , they do not think nearly as much about what they learn , and this is the reason why they do not improve more rapidly
道理很明显，当动物像我们人一样在凭各种感官学习事物时，动物对所学的事物几乎不多加考虑，这就是之所以动物不能较迅速地提高的原因。 |
| 6. | One of those routes ? always the same one ? led to food . （ 2 ） the researchers measured how quickly the animals learned by seeing how long it took hungry birds to choose the correct route on five of six consecutive tests
在6个连续实验的5个实验中，研究人员通过观察饥饿时这些鸡选择正确路线所耗费的时间，从而测算出它们的学习速度。 |
| 7. | The adult brain shows remarkable plasticity , learning - induced plasticity is that an awake animal learns the association between two events and modifies processing ability of its brian to specific information and thus change its behavior as a function of the learned association
成体脑存在显著的可塑性。学习诱导的可塑性是指动物学习两个事件之间的联系而产生的脑对特定信息处理功能的改变并能随之调整本身行为的现象。 |
