Chunking ERA help!

So for an ERA we are doing an experiment of increasing the capacity of short term memory by chunking and not chunking (seeing which one is better)

This is my introduction, but i feel it is to long, not detailed enough and doesn't cover everything like past experiments and theories. (Feel free to change it all) thank you everyone :)

Memory is often defined as the processing, storage and retrieval of information acquired through learning (Psychology units 3 and 4, Grivas john 2014, pg. 237). The nature of memory consists of duration (length of time), encoding (means of remembering) and capacity (amount of information). Short term memory refers to memory system with limited storage capacity in which information is stored.  The limit of STM is a range of 7 +/- 2 items of information.   The purpose of this research is to further previous findings and explore that capacity and how much the mind can remember or recognised after a short period of time and whether it can be increased by the process of ‘chunking’. Chunking is the grouping or packing, of separate bits of information into larger single unit, or chunk of information. The term itself was defined in a famous 1956 review paper entitled " The magical number seven, plus or minus two: Some limits on our capacity for processing information. As part of this hypothesis, it is predicted that participants will be able to recall more letters when it is in the form of ‘chunking’. Original research was performed in 1970, by Bower and Springton, where 20 participants were given a sequence of random and chunked letters. Through the results of this research, it can be concluded that chunking does in fact increase the capacity of short term memory. Other factors that assist short term memory is the serial position effect; comprising of primacy and Recency effect, assisting in improving recall of words both at the start and end of the presentation list.

You have already:
As part of this hypothesis, it is predicted that participants will be able to recall more letters when it is in the form of ‘chunking’
The recall is the DV, whether it is chunked or not is the IV, plain and simple.
However, my personal opinion is that instead of "participants", you should specifically refer to your population (3/4 Psychology Students at [your school] etc.)

Also, as a general criticism (although just my personal opinion - I'm not a past student so feel free to dismiss this). I think you trip yourself up at the end. For future students also, I'll give my two cents.
First, I don't think you should be worried about making it too long. At least for my school, the discussion and introduction are most heavily weighted. That means you can afford to put detail into it. My teacher describes our introduction as a funnel that gets more specific as it goes on. First, you should start with a broad overview of the study and what key terminology means. You've done that really well :) Next, you should discuss the study in more context, which is the previous research. So essentially, what you've put at the end should come in the middle. Finally, the most specific - your own study - is placed at the end, and should include your hypothesis. You have successfully done this also before mentioning the previous study.
Also, the results as far as I know are only included in the abstract, not the introduction. Of course the results from the previous study are acceptable, but you should not mention your own results.

To conclude, I rearranged your sample. You of course can disagree with it but it might help to compare the frameworks other schools are using. Our school is not especially strong in psych but we usually get a few forties and we got a 47 in 2014 (pretty good for a regional school).

Memory is often defined as the processing, storage and retrieval of information acquired through learning (Psychology units 3 and 4, Grivas john 2014, pg. 237). The nature of memory consists of duration (length of time), encoding (means of remembering) and capacity (amount of information). Short term memory refers to memory system with limited storage capacity in which information is stored.  The limit of STM is a range of 7 +/- 2 items of information. Ways of enhancing the capacity have been extensively researched in 1970, by Bower and Springton, where 20 participants were given a sequence of random and chunked letters. Chunking is the grouping or packing, of separate bits of information into larger single unit, or chunk of information. The term itself was defined in a famous 1956 review paper entitled " The magical number seven, plus or minus two: Some limits on our capacity for processing information.

edit; reading this again it sounds still a little clumsy but I'm sure you can tidy it up

sarangiya's points are mostly pretty good, but i was just wondering if you need that in intext citation?
Memory is often defined as the processing, storage and retrieval of information acquired through learning (Psychology units 3 and 4, Grivas john 2014, pg. 237).
I wouldnt think it would be required in VCE psych, but not sure. I'm pretty sure just a name drop like you have in there with Bower and Springton is fine.
but if your teachers say otherwise then listen to them

I can also confirm this :) Just the shortened citation with the full reference at the end. Nice pick up - I didn't even see it.
