Hi Michael: First, notice that you have switched to a new response. You are now posting text or pictures and you hope that your posts will produce more emails or likes or whatever.
The previous analysis still applies. Assume that you post 4 pictures to Instagram and you get one response. The question is what happens when you post 8 pictures in about the same amount of time. If 8 pictures produce two responses then you are talking about a VR type of schedule. If posting 8 pictures and then 16 pictures still produce only one response then you are dealing with a VI schedule. One point worth mentioning is that a common reason why students have problems doing such analyses is that they switch responses in the middle of an analysis. I have students do a lot of mother-daughter and father-son interactions from the perspective of both actors to help them learn to resist changing the response in the middle of an analysis.
