What I missed out as a child is what I crave most now.
Let me take this idea even further. We all know that there are two factors involved in creating who I am as a person. One pertains to "nature"; some quality that is already present at my birth and may in part be genetically inherited. The other pertains to "nurture"; the quality of the physical environment in which I was raised including how my parents and others cared for me. And while the debate still continues about which is most critical my belief is that both are equally so.
So what does all this have to do with Love?
My point here is that if my physical needs were taken care of as a child then it's fairly likely that will not be the love language test language I seek. On the contrary if I was not told, or did not hear, often enough that I was valued and loved and wanted as a child then it is likely that this will still be what I crave most and will be the love language I seek and respond most to.
