It works on the principle of introducing the topic of the paper and setting it in a broader context, gradually narrowing the topic down to a research problem, thesis and hypothesis.

In many fields, this could make up an entire essay in itself, so be careful to stick to only relevant information.
The background then leads into the rationale behind the research, revealing whether it is building upon previous research, looking at something that everybody else has overlooked, or improving upon a previous research project that delivered unclear results.
You should also highlight any assumptions that you make about conditions during the research.
You should set out your basic principles before embarking upon the experiment: any research will be built around some assumptions.You can also think of the Introduction as the section that points out the gap in knowledge that the rest of the paper will fill, or the section in which you define and claim your territory within the broad area of research.The other job the Introduction should do is to give some background information and set the context.If you want others to cite your paper, you should make sure they read it first.Let us assume that the title and the abstract of your paper have convinced your peers that they should see your paper.As long as you warn the reader about this, so that they are aware of the shortcomings, then they can easily judge the validity of the research for themselves.This is much better than making them wait until you point the weaknesses out in the discussion.This concluding part of the Introduction should include specific details or the exact question(s) to be answered later in the paper.At the same time, the introductory statement should not be too broad: note that in the examples above, the Introduction did not begin by talking about agriculture, cancer, or batteries in general, but by mentioning organic matter in soil, the role of bacteria, and lithium ion batteries.A behavioral science paper only needs to mention Pavlov and Skinner in passing, as their theories are standard for any first year undergraduate.Like in any good Hollywood movie, the first task of the introduction is to set the scene.
