00:00:00,300 --> 00:00:04,920
The goal of your literature search should be to create an overview of the literature.

2
00:00:05,040 --> 00:00:07,150
So in this lecture I want to show you how I do that.

3
00:00:07,740 --> 00:00:09,360
Okay so this is google scholar.

4
00:00:09,360 --> 00:00:14,640
I'm going to use Google Scholar to illustrate how I create an overview of the literature and let's say

5
00:00:14,640 --> 00:00:16,950
that my topic is depression.

6
00:00:17,190 --> 00:00:23,820
So I'm going to type in depression and we just said in the example that it's about a new view on depression

7
00:00:24,450 --> 00:00:28,560
and let's just say that this is the cognitive view... just for this example.

8
00:00:28,880 --> 00:00:35,400
We're going to search for that and now I get a couple of papers and here I always see the title,

9
00:00:35,640 --> 00:00:42,360
and underneath I see the author and the Journal and the time in which it's published. And look at that,

10
00:00:42,360 --> 00:00:48,570
the first title already says: "A meta analysis of the efficacy of cognitive therapy for depression."

11
00:00:48,600 --> 00:00:55,770
So a meta analysis is not the same as a review but it's almost equally good. A meta analysis is when you analyze

12
00:00:55,770 --> 00:00:57,930
the results of several studies together.

13
00:00:58,200 --> 00:01:03,000
So I can already tell from the title that this paper is very likely to give me an overview of relevant

14
00:01:03,000 --> 00:01:05,150
research on my topic.

15
00:01:05,220 --> 00:01:06,520
So here's what I'm gonna do.

16
00:01:06,540 --> 00:01:13,110
I can actually get a full version of the article here and I'm going to click on "download as" and then

17
00:01:13,110 --> 00:01:17,710
I'm gonna download it to the desktop. Save.

18
00:01:17,760 --> 00:01:19,260
Here it is.

19
00:01:19,440 --> 00:01:24,590
And now instead of opening it, I will drag and drop it into Mendeley.

20
00:01:24,600 --> 00:01:25,650
There we go.

21
00:01:25,650 --> 00:01:26,890
Here it is.

22
00:01:27,030 --> 00:01:31,920
And now I can open it in Mendeley and here it is.

23
00:01:32,130 --> 00:01:37,120
Now the first thing I do is check whether Mendeley extracted all the information correctly.

24
00:01:37,230 --> 00:01:42,630
So I see here for example that it extracted the title correctly and I also see that it extracted the

25
00:01:42,630 --> 00:01:49,490
author correctly but it didn't catch the journal and it also got the year wrong.

26
00:01:49,670 --> 00:01:52,890
And so here are a number of things that I need to correct here.

27
00:01:53,120 --> 00:01:56,020
So I'm gonna do that quickly. And there it is.

28
00:01:56,030 --> 00:02:01,940
Now all the information are correct and this is important because Mendeley is later gonna use this information

29
00:02:01,940 --> 00:02:04,340
to construct the references.

30
00:02:04,340 --> 00:02:07,130
So we need to make sure that these information are correct.

31
00:02:07,130 --> 00:02:12,940
Sometimes it will get all the information correct by itself but sometimes we also need to help it out.

32
00:02:13,040 --> 00:02:15,440
Then next I'm going to create a summary of that article.

33
00:02:15,470 --> 00:02:22,940
So here for example it say that: "The results document a greater degree of change for cognitive therapy

34
00:02:23,540 --> 00:02:27,300
compared with a waiting list or no treatment control,

35
00:02:27,340 --> 00:02:32,140
pharmacotherapy, behavior therapy, and other psychotherapies.

36
00:02:32,510 --> 00:02:35,450
So apparently the cognitive treatment is very effective.

37
00:02:35,480 --> 00:02:46,580
So I'm just gonna write down that the cognitive treatment works very well and I'm gonna go to the article

38
00:02:46,580 --> 00:02:48,380
here in my library.

39
00:02:48,380 --> 00:02:56,300
I'm gonna go to copy as formatted citation and then I'm gonna put the citation underneath.

40
00:02:56,330 --> 00:02:57,260
So here we go.

41
00:02:57,810 --> 00:02:58,340
And there it is.

42
00:02:58,340 --> 00:03:03,440
I'm gonna make sure that they are next to each other and then I will just go further and find the next

43
00:03:03,440 --> 00:03:08,950
article and write down again what I learned from this article and put the reference underneath.

44
00:03:09,190 --> 00:03:13,610
And if you keep doing that you should end up with a list of references and what you learned from each

45
00:03:13,610 --> 00:03:14,600
reference.

46
00:03:14,600 --> 00:03:19,550
And we're gonna use that in the next lecture to construct the outline of your introduction section.

47
00:03:19,600 --> 00:03:19,880
All right.

48
00:03:19,880 --> 00:03:20,930
That's it for this lecture.

49
00:03:20,960 --> 00:03:22,460
And I see you in the next one.
