eg1 TPO18-L3 The Role of Spices
In order to really study the social history of the Middle Ages, you have to understand the role of spices. Now, this might sound a little spurring, even a little strange. But what seem like little things now were back then actually rather big things……
We can boil it down to there general ideas briefly. One was cost and rarity. Uh two was exotic taste and fragrance. And third, mysterious origins and kinds of mythical status. Now for cost and rarity…. Now for the taste…….So the cook started looking for new ways to improve the taste and spices were the answer, which brings us to mysterious origin and mythical status.
So the cook started looking for new ways to improve the taste and spices were the answer, which brings us to mysterious origins and mythical status. Now the ancient Romans had a thriving spice trade and they sent their ships to the east and back. But when Rome collapsed in the fifth century and the Middle Ages began, direct trade stopped, and so did that kind of hands-on knowledge of travel and geography. Spices now came by way of the trade routes with lots of intermediaries between the producer and the consumer. So these spices took on an air of mystery.
Why does the professor mention the collapse of the Roman Empire?
A. To indicate that the spice trade became more direct
B. To explain why the price of pepper suddenly increased
C. To indicate that spices were not available in Europe for centuries
D. To explain why the origins of spices became more mysterious
OK, now I wanna talk about an animal that has a fascinating set of defense mechanisms. And that's the octopus, one of the unusual creatures that live in the sea…. the octopus can go through all kinds of incredible transformations. And it does this in three ways: bychangingcolor, by changing its texture, and by changing its size and shape.
eg3 TPO4-L1 Displacement Activity
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.
———————————————————1. 通过具体例子来说明什么叫做Displacement Activity —————————————
Pro: So, what do you think another example of a displacement activity might be? （提问分层）
Karl: How about an animal that, um, instead of fighting its enemy or running away, it attacks a plant or a bush?
Pro: 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.
———————— 2. 教授提问引出第2层次，通过学生的错误例子引出什么叫redirecting —————————
Pro: Ok, who else? Carol? (提问分层)
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?
Pro: 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’.
Pro: 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.
———————————————————— 3. 教授提问引出inhibition———————————————————————————
Pro: 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? (提问分层)
Karl: Maybe because it’s easy for them to do? I mean, grooming is like one of the most accessible things an animal can do. 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.
—————————— 4. 教授提问引出—为什么displacement activity 总是那些comfort behavior—————————
Carol: Professor, isn’t it possible that animals groom because they’ve got messed up a little from fighting or mating? 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. (提问分层)
Pro: That’s another possible reason although it doesn’t necessarily explain other behaviors such as eating, drinking or sleeping.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. For example, there’s a bird, the ‘wood thrush’, anyway, when the ‘wood thrush’ is in an attack-escape conflict, 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. If it’s sitting on a vertical branch, it’ll groom its breast feathers. 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.
