Single sample, 4 questionnaires, 2 internal state and 2 external reaction - how to analyse

#1
I want to confirm I have been using the correct analysis, would welcome ideas as to which statistical analysis calculations you would use for this research.

Let's call the internal states "A" and "B", and the external reactions "1" and "2".

The data will be measured as interval, parametric.


List of comparisons:

How does A affect 1
How does A affect 2
How does B affect 1
How does B affect 2
How does A affect 1 & 2 simultaneously
How does B affect 1 & 2 simultaneously
How do A and B affect 1 and 2 - (MANOVA - to give you an idea of where I am going with this)
