So I had my first write up for this "folio SAC" which I am not really familiar with and I felt really crap afterwards because I wasn't really sure what was going on. Today's write up was on the Pavolv study. And I got confused about certain things:
1. Operational hypothesis - I'm usually used to writing hypotheses that compare something, like if something has this IV it will be better than if it had this other IV or something, but I don't see how it would work for this experiment
2. I think the dependent variable in this experiment would be the amount of salivation but would the IV be which stimulus was used (The NS/CS or UCS) or if it was the number of trials...? (since after more trials of association, there was more saliva, but then it would decrease after the UCS was removed).. I don't know :( So I'm even confused about the IV and DV in this experiment
3. I wasn't sure how to describe the procedure because it ended up looking pretty short to me (associating the two stimuli until acquisition then removing the UCS.... then what)
YEAH so I was pretty stressed after that and I'm still quite lost on what to do for this weird SAC.
Any help from people who have previously done it or who has a good idea on what it's asking.

I don't really know much about the sac, but I think something along these lines may work.
IV: Meat powder (CS) being repeatedly paired with the sound of a bell (neutral stimulus)
DV: The amount of salivation produced by the dogs in response to the sound of a bell.
And for the operational hypothesis, you could perhaps talk about how the dogs will salivate more to the sound of a bell when the sound of a bell has been repeatedly paired with meat powder, compared to levels in response to the sound of a bell when the sound of a bell has not been paired with the meat powder.
