Lab Report Intro

Im a second year psychology student, so I need to make sure my lab report is good!

The topic is animal phobias and the study is aimed at deciphering whether there is a relationship between ugliness (of an animal) and fear of animals using partial correlation to control for effects of percieved harmfulness.

I feel my introduction must have something huge missing because I am finding it WAY too easy to get everything within the 550 word limit for the intro. Usually I have so much to get in it is ridiculously hard.

I have these sections in my intro:
-Brief statement of what the study is aiming to assess
-Why this is an interesting topic
-Previous research (main psychology schools involved leading on to some specific examples)
-Explanation of a previous study that the present study is based on,
including its weaknesses
-How the present study attempts to rectify these problems
-Null and Alternative Hypotheses

Can anyone think of anything glaringly obvious that i have left out, I really feel it shouldnt be this easy! If not please reply and say no so I feel better!

Thanks

OP, you have included some very strange topics in your intro which should not really be there. In particular, you have included discussion about the study you have completed which really does not belong in the introduction!! This kind of topic belongs in the discussion and the discussion only (e.g. AFTER your methods and results, it doesn't make chronological sense otherwise).

Essentially, your introduction needs triangular directionality. That is to say, it should be an introduction to the coherent body of research that has already been done which starts very broad, slowly filtering down to the more specific to come to your hypothesis at the end of your introduction where a short rationale can be included. This research must be from the school of psychology that your hypothesis belongs to, don't swap back and forth from say, behaviorism to cognitive.

You should NOT be discussing downfalls or rectification of problems here. This belongs at the end of the discussion section. Has your department asked for you to do this? This isn't how journal articles are written, which is essentially what you are practicing.
