Term for incentives working without conscious awareness
Annoyingly, it depends what area of the research literature you happen to find yourself in. In the perception literature, the distinction lies between subliminal and supraliminal. In the memory and learning literature, the distinction lies between implicit and explicit. In dual-process decision-making theories, the distinction lies between automatic and controlled. The former terms broadly refer to "unconscious processing" while the latter terms refer to "conscious processing," but I wouldn't say unconscious/conscious is a well-defined distinction.

There is some general cross-overlap, but of these three distinctions and areas, the distinction that sees the most use in the other two areas would have to be explicit/implicit. They differ mostly in what stage of the process in the mind the researcher is interested in: perception, memory or thought. There is, to my knowledge, unfortunately no term which broadly captures all unconscious processing from input to output AND maps to the literature. 

If you want the term to map to the literature, I think you'll have to commit to one or another. If it's for a lay audience, "implicit X" is fine, where X is whatever you think best fits the intended meaning.
