Yes, the same word in different context can have different operating definition (like "species" - different in vertebrate zoology and in microbiology; or "gene" - different in population genetics and genomics). We know that without philosophy guiding us.
And our domain knowledge makes us see why insisting on unifying definition is a waste of time - the definition would have to be so abstract as to be useless for practical work. (I cannot say anythiing about how psychologists use "control", but I doubt that they are unaware of how they do it.)
