Some of the most practical lessons coming out of research in psychology are the area of memory. People ask, why can’t I remember that term from the physical charge or the library books in due? Of a lot of people, memory may be weak, because they don’t use it enough. It’s like muscle if you don’t exercise it, it won’t get strong. That’s why it’s important to keep our mind active, to keep on learning through our life, we can do this by reading, playing memory game and seeking out #. It’s my guess though that the lack of stimulation isn’t a problem for students like you. More likely, the life u r in is so busy and stimulating that it’s itself may sometime interfere with learning. Later on I will discuss how information is recorded from memory. But, first, the information needs to be recorded, in other words, learned. And for busy people like u and me, that will be the real problem # the lines. If we are distracted, or we are trying to think what we are going to do next, the incoming message just might not be getting recorded effectively. And that leads to the first tip for students who want to improve their memories. Give your full attention to the information you hope to retain. Research clearly shows the advantages of this, and also of active learning, of consciously trying to visualize a new fact, perhaps to make a mental picture, even a wild ridiculous one, so the new fact will stick in memory. Let me illustrate that for u here a little more this evening.

Q 43: What’s the talk mainly about?
Q 44: What does the speaker illustrate with the example of muscle?
Q 45: What does the speaker suggest students do to learn new information more effectively?
Q 46: What will the speaker probably do next?

Listen to part of a talk in a biology class. The professor is discussing insect behavior
Today, we are going to continue our discussion on social insects, focusing on the
Argentine ants, which as u might guess is a species of ants that are natives to Argentina.
We’ll consider what happened to this type of ant after some members of the species move
to California from their original habitat. Ok, well, in Argentina, these Argentine ants behave
like most ant species around the world. They fight other ants of the same species if those
ants are from some other nests. But the Argentine ants living in California behave
differently. Ants from different nests form a single large colony. Within this colony, there is
little aggression among ants from different nests. And when they fight with insects from
outside their colony, the Argentine ants can quickly recruit a huge army from their network
of nests. This of course gives them advantages over other ants’ species. So then, why do
Argentine ants behave differently in California than they do in Argentina? Well, using
genetic testing, researches found that all the Argentine ants in California were very similar
genetically. You see, when the first Argentine ants came to California, their population
must have been very small and all the later generations of Argentine ants there must have
descended from the same few ancestors. So they are all closely related. This discovery is
important, because for most social insects, membership in a colony is based on how
closely related they are genetically.

Q 47: What aspect of Argentine ant is mainly discussed?
