I should note: that I am talking about NEW aspects of behavior patterns (I have no argument with the idea that things-known can be "put together", though not in qualitatively new ways).
Truly NEW learnings (as in qualitative changes) must be concrete : EVEN the inception of the most 'abstract' types of representation and thought (and learnings). [( Though it used to be said that we can deal with 7 + or - 2 "chunks", lately there is a consensus developing that: for significant processing/learning, working memory uses only about 4 "chunks". )]
If you accept the results on our types of memory (about the strongest and most reliable and clearest results in all psychology) and if you have any reasonable (and common) definition of thinking and of specific progress occurring with that thinking, you must believe that EVERYTHING mental (covert) and reliable must have (at least at its inception) directly observable concrete proximate cause(s) in aspect(s) of a clear and present environment.
Much of the learning that occurs would likely require this just based on CAPACITY issues; in any case, it should also be clear that without this being the way it is, it is not likely learning would reliably reflect our environment (errors, like those that do occur would occur "all over the place" -- or tell me why this wouldn't be the case).
Accept all this and BONUS: You are an empiricist !! [ Here is perhaps another interesting thing to think about, if you are an empiricist: If concrete aspects of the present environment would (sometimes?) not need to be involved in significant NEW learnings, THEN the person would have to successfully remember such the "things" that are involved -- AND somehow develop and involve the new type of learning, as well. Perhaps some think this is what some old-time philosophers did, BUT they had already developed adult thinking, thus all the major qualitative changes -- in learning and thinking -- had ALREADY occurred (and see my first statement, at the top of this page). ]
Go ahead and try of describe 4 "chunks" (some with NEW content AND EVERYTHING PROCESSED properly) which does not hinge on direct experience in the environment ! (Do not try to describe the case with the environment as somehow being represented in 'sensori-motor' type responses, and THEN with those going forward -- this last part BEGS THE QUESTION, don't you see?; "Embodied 'theory'" is not only not well-founded but obviously incomplete on how behavior change can move forward, thus begging the question; and this is not to mention the 'evidence' is poor, outrageously indirect, and the theory has been shown useful for nothing and there is no reason to believe it has any promise -- there is no reason to 'believe it' at all, unless perhaps you fear a professor.

(1) Given what is not possible, just indicated, you need to change in some ways: it is not likely that it is fruitful or useful to think in terms of single behavior (or sets you define) but in terms of BEHAVIOR PATTERNS (discovered); (2) you must accept there is some not-yet-commonly-recognized guidance for perception/attention/learning: INNATE guidance, even very late in ontogeny; (3) that it is highly unlikely that it is adequate to try to delineate only the simplest learnings (classical and operant) AND the vague "social learnings" (otherwise) as the only learnings we type and classify; I see that we do this as another sign that psychology has not yet hardly even begun; (4) You, related to (1) - (3), need to accept something like Ethogram Theory -- which rather well justifies itself and provides a way to define what must be defined and sees things in terms of the way they must be (or sometimes perhaps, in part, describes the way "things" could be, while remaining utterly directly empirical); it also shows all the major theories as clearly flawed (and convincing so, EACH in very similar ways). It is time for "out with the old and in with the new". (I have other essays here on researchgate for explication, describing other related perspectives and implications and ramifications.)
[ In short: with the brief, clear indications of a good argument, above, you a NEED a new way of thinking, such as I describe in "A Human Ethogram ... ". ]
