WHAT? "Non-conscious perception": isn't that an oxymoron; isn't anything like that SENSATION?? NO. Such conclusions involve one believing he/she knows all the sorts of species-typical basic, primary kinds of perception AND that all that is innate is present at birth or in infancy; THESE [mere] beliefs, very likely are associated with incorrect ill-founded (and groundless) pseudo-'assumptions': these quickly leading to wrongful conclusions -- these conclusions often also "taken" (put forward) as "assumptions". A LOT of this is part of our "culture" based on the views and ways of old-time philosophers. Staying grounded and doing all one can to be well-founded, based on what little reliable and true data exists, I HAVE SHOWN THESE bad things TO BE THE CASE IN MY WRITINGS.
I do believe that the inception (the beginning, just the beginning) of cognitive-developmental stages occur as perceptual shifts, each with 2 phases being non-conscious, and with 2 later stages involving attention. [ Why? Let's face it: BIOLOGY does not likely need our attention for beginning all major developments, and maybe not for ANY, for that matter. ]
I believe, based on hundreds of pages of realistic, grounded, reading and empirical thinking, and very mindful of good, central data -- especially, specifically: on the Memories (and most-notable the importance of visual-spacial memory for all higher organisms) and on the likely actual ubiquitous-ness of associative learning -- that these "perceptual shifts" EXIST AND are subtle overt directly observable behavior patterns (seen in real-time), detectable NOW with the new eye-tracking technology (and computer-assisted analysis). As empiricists, we MUST believe this, if we do not know better.
Way back in 1985 I did propose a very basic similar well-founded outline on how to very empirically start a human ethogram, in the way indicated. ONLY PROBLEM (but it was a BIG one) was that the type of hypotheses, WERE AT THAT TIME, _NOT_ TESTABLE. [ (I did, way back then, start to show quite well some of the major interpretation problems due to "pseudo-assumptionism" ; in more recent writings I have found the baseless beliefs, serving as basic "assumptions", behind these other assumptions -- all "spelled out".) ]
Most importantly:
The fact of the matter is that NOW (in the present) such hypotheses have become researchable: the type of hypotheses -- now further specified in recent Collected Essays (and a connected Comment and Replies) -- can NOW be tested/verified , specifically with eye-tracking technology (and, perhaps, also using computer-assisted analysis). (I have waited over thirty years for this.)
The 328 pages of NEW (< 1 yr old) supporting essays (the Collected Essays), fully explicating and further and completely justifying the perspective, AND refining and specifying the hypotheses, are now available.
Links to both the main 1985 160-page paper (still good and needed to be read), a treatise, entitled "A Human Ethogram ... ", and the Collected Essays (of 328 pages) can be found through the researchgate link:

In addition, for your convenience, I shall provide (with this Post) AN attachment (attached as the rich-text document, Comment2Replies.rtf): this contains the later posts (in a Comment and Replies), associated with the Collected Essays. That will give you a "taste" of things.
