You will now read a short passage and then listen to a talk on the same academic topic. You will then be asked a question about them. After you hear the question, you will have 30 seconds to prepare your response and 60 seconds to speak.
Diffusion Effect
Depending on the context, the term "diffusion effect" has a large number of possible meanings. In medical, psychological and sociological research, however, the term refers to inappropriate contact between study groups. Ideally, of course, groups of subjects should be completely unaware of each others' existence. Failing this, it is an absolutely essential minimum requirement that no exchange of information between or about the groups take place. This is so since such information, in effect, "taints" any data obtained from the group. The response of any group must be spontaneous and not a reaction to what it knows about the other research groups.
Now hear a talk on the same subject.
Question: Using information from the reading and the lecture, explain how the lecture is related to the reading passage.
【正确答案】The lecture is about an academic concept called diffusion effect which refers to a contact between two research groups which should be kept strictly separate.
The professor in the lecture explains this concept by giving an example.
According to the lecture, there was a test participated by two groups. One group was tested first. Unfortunately, when the second group was due to be tested, they overheard a researcher talking about the first group's high score results. The second group seemed anxious about their performance and final score for being worse than that of the first group. Considering the level of pressure would affect the second group's attitudes and the test result, a new group had to be selected. The reason of starting the test all over again is that the researchers wanted to see a group's ability to fulfill a test, not its reaction to another group.
