"Students on Campus"
What is the study about?
Narrator: Listen to part of a conversation on campus between two students.
Woman: This is an interesting assignment.
Man: It is. I’m just having a problem figuring out how to write up the report. Q18
Woman: Oh? How much have you done?
Man: Well, the introduCtiOn was easy, Ijust expaned on the nformation that the lab Q19
assistant provided, you know, about the effects of alcohol on reflexes, and I used the same
references that he cited.
Woman: Me, too.
Man: Then I described the experiment in the second part... the methods and materials
section. Woman:What did you include there? The lab assistant said that it was important to be specific
when we did this part.
Man: Yeah, he did. So I mentioned that there were ten subjects, and five were drinking gin
and tonic, but the other five... that’s the control group... they were drinking tonic only,
and no one knew which group was which. Then they each had to drive in a
computerized... what was it called? A... a simulator... a simulator of a car that was supposed
to be moving at 35 miles an hour. And when they saw a bicycle, they were supposed to
hit the brakes.
Woman: So far so good. The only thing I can think of that you might want to add is maybe a little
more about the subjects. I think they were college students, and they were selected at
random to be in the experimental or control group.
Man: Good idea. Especially the part about the random selection, That would be imporant Q20
information if someone wanted to duplicate the experiment, and didn’t he say that this
section had to be specific enough for another researcher to be able to repli...repli...
Woman: replicate.
Man: Yeah. Replicate the study.
Woman: Okay, so what did you do with the results section?
Man: That’s the problem. I can’t seem to figure out what to put in the results section and what
to use for the discussion section. If I put the chart with the reaction times in the results,
should I explain the chart in the discussion, or what?
Woman: Oh now I see the problem. The charts fairly self-explanatory, isn’t it? I mean, it’s really Q21
a simple chart to read.
Man: That’s what I thought.
Woman: But you still have to explain the chart in the results section.
Man: You do?
Woman: Yeah. Um, look, here’s what I’d do. I’d look at the chart and try to come up with a few
general statements. For example, um well, all of the subjects who were drinking Q19
alcohl had longer reaction times. Then you can look at the range--1 second to 4 seconds
for the subjects who were drinking only tonic, and that’s compared with 3 seconds to 20
seconds for the subjects who were drinking gin with the tonic.
Man: So, I’m really just repeating what’s on the chart, but I’m explaining it in words.
Woman: Right. But, here’s the thing—you shouldn’t draw any conclusions in the results section.
Just the facts.
Man: You mean, just what happened in the experiment.
Woman: Right. You have to save the conclusions for the discussin sectin. Q22
Man: Okay. So in the conclusions, I might say that driving after having four drinks... if you
have four drinks, you probably won’t be in a position to avoid an accident.
Woman: That’s good. And you could also point out problems in the research, if there are any, or
suggestions for future research.
Man: Like doing the experiment with beer instead of hard liquor or repeating the same
experiment with three drinks instead of four.
Woman: Sure. That’s the idea.
