protean, in its new avatar and, proceptivity

I submit that "protean signals" is a mongrelization, mistakenly related to "proceptivity" which has its in true origins in the term "sexual receptivity", as follows:

Most nonhuman female mammals have a cyclic ovarian estrus cycle, during which they have a fairly limited period of sexual receptivity and emit olfactory, and behavioral signals of their willingness to copulate (Daly & Wilson, 1983).

proception signals is the proper term, but, as with many mongrelisms, it is not so vivid, and, therefore, not so useful for marketing purposes [in this case, promoting a book on female courting habits].
