Uhh, nope. Shadow functions essentially always refer to those non-preferred functions -- in the INTP's case these are Te, Ni, Se, and Fi, in order of decreasing preference. The questions is always to what extent these are actually present in each type's personality, or whether they have any significant influence at all.
I have always accepted the Socionics school of thought on the issue, which is that information related to all 8 functions can in some sense be said to exist "objectively", and each type has a certain relationship to each type of information. In this theory, INTPs are strong with Ti, Ne, Te, and Ni, but they prefer Ti and Ne and find Te and Ni to be superfluous and generally not worthy of consideration. By contrast, INTPs are weak with Si, Fe, Se, and Fi, but have a preference for Si and Fe, generally finding Se and Fi to be discomforting and creating feelings of insecurity and low self-worth. Minor differences in particular orientations describe the differences between INTPs and ENTPs despite their valuation and aptitude for the same functions in each category.
What this means to me is that one does not "use" their shadow functions. I've always found that idea silly. What's the point of coming up with this theory about each type's differences in interaction with these functions if the end result is all of us being the same anyway? I think the more appropriate view is that one can improve how one handles the "shadow functions", but should recognize that it pertains to a different sort of information that one might not find easy to handle or even desirable to deal with. I know I personally have a ton of issues with Fi and Se types and information (the former of which I can find somewhat annoying and the latter of which terrify me). I can improve in how I deal with these things, and recognize my biases there, but I don't think it's really possible to attain healthy and positive "use" of these functions. It's more something to work around and come to terms with.
