托福TPO/Official 4 Lec 1听力原文What does the professor mean when she says this：-新东方托福官方网校手机版

旁白：请听一段生物学课上的演讲。

Narrator: Listen to part of a lecture in a biology class.

教授：好的，接下来我要讲到的动物行为，大家可能都很熟悉。

Professor: Ok, the next kind of animal behavior I want to talk about might be familiar to you.

比如，你们可能见过某一只鸟在进行交配过程中，突然停下开始整理羽毛，像，花了几分钟时间把自己的羽毛整理齐，然后又回到交配状态。

You may have seen, for example, a bird that's in the middle of a mating ritual, and suddenly it stops and preens, you know, takes a few moments to straighten its feathers, and then returns to the mating ritual.

这种行为，这种似乎完全突发性发生的行为，就是我们所说的“转移行为”。

This kind of behavior, this doing something that seems completely out of place, is what we call a ‘Displacement Activity’.

转移行为指的是当动物遇到冲突性驱动的时专注于一身的某些行为。

Displacement activities are activities that animal's engaging in when they have conflicting drives.

我们看一下刚刚举到的例子，如果那只鸟害怕其交配伙伴，它便面临着冲突。

If we take our example from a minute ago, if the bird is afraid of its mate, it's conflicted.

它想交配，但也因为害怕想逃离。

It wants to mate but it's also afraid and wants to run away.

所以，反之，它开始整理自己的羽毛。

这样，转移行为，即整理羽毛，将自己的羽毛理齐了，似乎是一种毫无相关的行为。

So, the displacement activity, the grooming, the straightening of its feathers, seems to be an irrelevant behavior.

那么，你们知道另一个转移行为的例子可能是什么吗？

So, what do you think another example of a displacement activity might be?

Karl：嗯，这个例子怎样：动物没有进攻敌人或逃跑，反而攻击某一棵植物或灌木丛。

Karl: How about an animal that, um, instead of fighting its enemy or running away, it attacks a plant or a bush?

Professor: That's really good suggestion, Karl.

动物正在将其行为重新指向到另外的物体上，在这里，是指某一植物或灌木丛。

The animal is redirecting its behavior to another object, in this case, the plant or the bush.

但这可不是一种无关或不恰当的行为。

But that's not an irrelevant or inappropriate behavior.

It's appropriate under the circumstances.

而没有任何意义的则是其行为指向的物体。

But what doesn't make sense is the object the behavior's directed towards.

Carol：我想我在另一节课上读过关于一次实验资料，实验中将动物所害怕的东西放在其食物旁，就在动物的食物旁。

Carol: I think I read in another class about an experiment where an object that the animal was afraid of was put next to its food – next to the animal's food.

而动物纠结于面对害怕的物体和进食两难中，它选择了睡觉。

And the animal, it was conflicted between confronting the object and eating the food, so instead, it just fell asleep.

转移发生的时候动物是面临着两种冲突的驱动，两种相互矛盾的冲动，在这个例子中，就是恐惧和饥饿。

Displacement occurs because the animal's got two conflicting drives – two competing urges, in this case, fear and hunger.

而接下来发生的就是，两者会相互抑制，他们会以某种方式相互抵消，而此时第三方，似乎毫无相关的行为就会出现，我们称之为“抑制解除”。

And what happens is, they inhibit each other, they cancel each other out in a way, and a third seemingly irrelevant behavior surfaces through a process that we call “Disinhibition”.

而抑制解除，基本上的意思是两种驱动似乎会抑制或克制第三种驱动。

Now in disinhibition, the basic idea is that two drives that seem to inhibit, to hold back, a third drive.

或者，嗯，他们会在一种冲突的情况下相互阻碍，

Or, well, they're getting in a way of each other in a... in a conflict situation and somehow lose control,

有时会失去控制，失去对第三种行为的抑制作用。

lose their inhibiting effect on that third behavior, which means that the third drive surfaces, it’s expressed in the animal's behavior.

那么，这些转移行为包括吃喝，整理羽毛，甚至睡觉。

Now, these displacement activities can include feeding, drinking, grooming, even sleeping.

这些是我们所说的“中和行为”。

These are what we call ‘Comfort Behavior'.

那么你们为什么会认为转移行为经常都是中和行为呢，比如休整羽毛？

So why do you think displacement activities are so often comfort behaviors, such as grooming?

Karl：也许是因为他们更容易这样做？

Karl: Maybe because it's easy for them to do?

我是说，休整羽毛就像是动物最容易上手的行为。

I mean, grooming is like one of the most accessible things an animal can do.

这是他们总会做的事情，而在他们身体之外存在着某些刺激物，让他们做出整理羽毛的行为，或者是食物就在他们面前。

It's something they do all the time, and they have the stimulus right there on the outside of their bodies in order to do the grooming, or if food is right in front of them.

基本上说，他们在做出这种行为的时候不需要想很多。

Basically, they don't have to think very much about those behaviors.

Carol：教授，有没有这样的可能，即动物整理羽毛是因为他们在交战或交配的是后把羽毛弄乱了。

Carol: Professor, isn't it possible that animals groom because they've got messed up a little from fighting or mating?

我是说，如果一只鸟的羽毛起皱，或某种动物的毛发，也许这对动物来说，看起来太奇怪了，所以他们需要整理一下自己的外观。

I mean if a bird's feathers get ruffled or an animal's fur, maybe it's not so strange for them to stop and tidy themselves up at that point.

教授：这是另一种可能因素，尽管不一定足以解释其他行为，像吃喝睡觉。

Professor: That's another possible reason although it doesn't necessarily explain other behaviors such as eating, drinking or sleeping.

有趣的是，某些研究已经表明动物的生活环境也许对其会表现出什么行为有决定性的作用。

What’s interesting is that studies have been done that suggest that the animal's environment may play a part in determining what kind of behavior it displays.

比如说，有一种叫画眉的鸟。不管怎样，当画眉鸟遇到进攻或逃离的冲突时，

For example, there's a bird, the 'wood thrush', anyway, when the 'wood thrush' is in an attack-escape conflict,

即当画眉鸟出于要不逃跑危险要不进攻敌人的境地时，如果它是停在水平树枝上的话，它会将自己的喙往栖木上磨。

that is, it's caught between the two urges to escape from or to attack an enemy, if it's sitting on a horizontal branch, it'll wipe its beak on its perch.

而如果是停在垂直的树干上的话，它便会整理其胸前的羽毛。

If it's sitting on a vertical branch, it'll groom its breast feathers.

鸟所处的即时环境，是即时的，其与这种即时环境的关系似乎对其表现出来的行为起到一定的作用。

The immediate environment of the bird, its immediate, um, its relationship to its immediate environment seems to play a part in which behavior will display.

Indicate whether each of the activities below describes a displacement activity.

What does the professor say about disinhibition?

According to the lecture, what is one possible reason that displacement activities are often grooming behaviors?

Why does the professor mention the wood thrush?

What does the professor mean when she says this：

Narrator 
Listen to part of a lecture in a biology class. The class is discussing animal behavior. 
Professor 
Ok, the next kind of animal behavior I want to talk about might be familiar to you. You may have seen, for example, a bird that’s in the middle of a mating ritual, and suddenly it stops and preens, you know, it takes a few moments to straighten its feathers, and then returns to the mating ritual. This kind of behavior, this doing something that seems completely out of place, is what we call a ‘Displacement Activity’. 
Displacement activities are activities that animals engage in when they have conflicting drives. If we take our example from a minute ago, if the bird is afraid of its mate, it’s conflicted. It wants to mate but it’s also afraid and wants to run away. So, instead, it starts grooming itself. So, the displacement activity, the grooming, the straightening of its feathers, seems to be an irrelevant behavior. So, what do you think another example of a displacement activity might be? 
This kind of behavior, this doing something that seems completely out of place, is what we call a ‘Displacement Activity’. 
Displacement activities are activities that animals engage in when they have conflicting drives. 
Karl 
How about an animal that, um, instead of fighting its enemy or running away, it attacks a plant or a bush? 
Professor 
That’s really good suggestion, Karl. But that’s called ‘redirecting’. The animal is redirecting its behavior to another object, in this case, the plant or the bush. But that’s not an irrelevant or inappropriate behavior. The behavior makes sense. 
It’s appropriate under the circumstances. But what doesn’t make sense is the object the behavior‘s directed towards. 
Ok, who else? Carol? 
Carol 
I think I read in another class about an experiment where an object that the animal was afraid of was put next to its food – next to the animal’s food. And the animal, it was conflicted between confronting the object and eating the food, so instead, it just fell asleep. Like that? 
Professor 
That’s exactly what I mean. Displacement occurs because the animal’s got two conflicting drives – two competing urges, in this case, fear and hunger. And what happens is, they inhibit each other, they cancel each other out in a way, and a third seemingly irrelevant behavior surfaces through a process that we call ‘Disinhibition’. 
Now, in disinhibition, the basic idea is that two drives that seem to inhibit, to hold back, a third drive. Well, well, they’re getting in a way of each other in a… in a conflict situation and somehow lose control, lose their inhibiting effect on that third behavior, which means that the third drive surfaces, it’s expressed in the animal’s behavior.
Now, these displacement activities can include feeding, drinking, grooming, even sleeping. These are what we call ‘Comfort Behavior’. So why do you think displacement activities are so often comfort behaviors, such as grooming?

It’s something they do all the time, and they have the stimulus right there on the outside of their bodies in order to do the grooming, or if food is right in front of them. Basically, they don’t have to think very much about those behaviors.
