Design two experiments (one true experimental design, and one quasi-experimental design) investigating the effect of video games on aggression

Please read mindfully and with focus:
Maximum word count: 3000 words total (1500 per report) Please note the following:
Students are required to indicate the exact word count on the title page of the
assessment.
The word count includes everything in the main body of the assessment (including in-text citations and references).
The word count excludes numerical data in tables,
figures, diagrams, footnotes, reference list and appendices. ALL other printed
words ARE included in the word count.
Please note that exceeding the word count by over 10% will result in a 10-percentage point deduction.

Now for the assignment itself:(1500 words per report, 3000 words total for the portfolio)

Your task is to design two experiments (one true experimental design, and one quasi-experimental design) investigating the effect of video games on aggression.
Each experiment should be presented in separate reports under separate titles – one
for the true experimental design, and one for the quasi-experimental design.
These
should be submitted together as one document, as a portfolio.
Once you have designed your true experiment and quasi-experiment, you should
write each of them up as two separate research reports with three sections in each
one: An ‘Introduction’ section, a ‘Methods’ section, and a ‘Validity and Ethical Considerations’ section.
Detailed guidance on how to construct each of these sections and
how to discuss ethical and validity issues can be found below and in the sessions for
the module.
Please note
You must not collect any data from participants for your study. You only need to design your study and write up the given sections of the report, as outlined below in the
“The details and structure of your research report” section
For more information, please see lesson two, “Components of experimental design”.
You can also share your ideas on the assessment forum. Then, your fellow students
and your lecturer can help you to figure out whether you have come up with an experimental and quasi-experimental design.

***IMPORTANT DETAILS***
The details and structure of your research reports:
Both reports must contain all of the following sections and sub-headings:

1-Title
Your title should reflect what the experiment is investigating. More specifically, it
should give an indication of what your independent variable was and what your dependent variable was in as few words as possible. For example: “The effects of
sugar intake on self-reported happiness”.

2-Introduction
In this section, you should very briefly introduce the topic area and explain why it is
an important area to conduct research into. You should then go on to discuss the
methods and findings of 3 existing research studies from the same topic area. You
should ideally consider your concepts of interest in the context of a relevant psychological theory. Next, you should explain how your own study builds upon (generates
new knowledge or replicates) the previous studies that you discussed earlier. Finally,
you should state the aim and hypothesis of your study. Your aim should be a general
summary of what you are trying to discover. Conversely, your hypothesis should be a
precise prediction of the effect that you expect your independent variable would have
on your dependent variable, if you were to actually run the study.

3-Methods
In this section, you should include enough information to allow someone
reading your report to conduct a full and accurate replication of your experiment. You
should also introduce the most important ethical and validity issues that are relevant
to your true experiment/quasi-experiment. This section should be written in the past
tense (as though you have already completed the studies). Please use the following
subsections within your methods section:

1) Design
Start by stating the type of experimental design used (e.g. repeated measures, independent groups or matched pairs for true experiments, and the explicit type of quasi-experiment) and very briefly explain why that design was the most appropriate one
for your study. Next, state what your independent variable was and what the levels
(conditions) of the independent variable were. Then, state what your dependent variable was and how it was operationalized (i.e. defined and measured). You should
also outline the control and random variables that have been considered in your
study.
For your true experiment, you must use an experimental design, so that you can determine cause and effect, such as independent groups design or repeated measures
design. For your quasi-experiment, you must use a suitable design, such as a nonequivalent groups design or pre-test, post-test.

2) Participants
This section should cover how many participants you collected data from, what the
range, mean and standard deviation of their ages were, what the gender distribution
of the sample was and what population you sampled from (you can make these up,
as you do not have to collect any data for this assignment). You should also outline
your sampling technique (e.g. opportunity sampling), You should also include your
inclusion and exclusion criteria for participation in the study.

3) Materials
In this section, you will need to use full paragraphs (not lists!) to provide detailed descriptions of the make, model and setup variables of each material, for each experiment. If you are using questionnaires or similar materials, then you will need to explain how many questions were asked, which specific ones were used, on what topics and (ideally) to provide an example question. You should also give scoring information. If you are using a computer task, then what stimuli were included in the task
and how many trials did the participant have to complete?

4) Procedure
This section should provide details of exactly what it was like to participate in the
study. In this section, you should outline the timings of each experiment. Therefore,
you should explain when and where consent was obtained, when, how and where
the participant engaged with each stage of the task and when and where each dependent variable was recorded, for both experiments. You should also explain when,
howand where the debriefing was conducted.

LASTLY:
***Validity and ethical considerations
In this section***
You should explain the ways in which you designed your methods to
be ethical and to ensure a high degree of internal and external validity.
You may split
this section into a paragraph explaining which precautions you took to ensure a high
level of ethical conduct and a paragraph to explain which precautions you took to ensure high levels of internal and external validity.
When describing each precaution,
you should explain how it improved the ethical conduct or validity of your study, rather than simply stating that it did improve them.

(300 words, in each report)

Relevance of proposed study, adherence to the brief and learning outcomes,
presentation and referencing
You will receive marks based on the relevance of your proposed study, and the extent to which you address the experimental question, and contribution to the wider
field. You will also be marked on your ability to plan a psychology study, and the extent to which you achieve the learning outcomes. You will also be marked on your
presentation, including appropriate use of subheadings; formatting; and how clear,
concise and scientific your writing style is. You will also be marked on your ability to
reference strong sources and using in-text citations and a reference list in line with
APA 6
th or 7
th edition.

***Referencing Guidance***
You MUST underpin your analysis and evaluation of the key issues with appropriate
and wide ranging academic research and ensure this is referenced using the APA
