BIG OVERALL QUESTION: How would one outline the steps in their building of a model that at all points was consistent with what we know about memory? : IN PARTICULAR, I am talking about the limited capacities of the various memories, no matter how sophisticated the "chunks" are or how sophisticated the contextualization of the episodic buffer and working memory can be: THERE STILL HAVE TO BE DEFENSIBLE "CHUNKS" -- which can be deliberately and clearly understood (or at least somehow particularly attended to), WITH NO JUMPS IN THE PROCESS OF DEVELOPING A MODEL BEING TOO BIG. (This may seem like an unanswerable question, but in arguable terms, and at least with arguably decent rough characteristics, we could show likely compliance with findings on and principles of memory. BUT IN THE MAIN: NO ONE even TRIES in Psychology -- violating some of the strongest, consistent, long-standing, replicable empirical findings in all of psychology (on the Memories). Stop pretending the inadequacies are necessary; try to stop "steeping yourselves" in inadequacy.)
This is why I totally hate MODELS; they are allowed to involve some incredible "cleverness" of those who develop them, the BIG QUESTION is never asked (seemingly, or at least it is not asked well), and the "clever" never feel the need to question themselves (nor are they required to): the huge "match" of features they PRETEND IS CLEAR; this leads to both ridiculous 'theories' in psychology -- and great fragmentation; this clearly is a (THE?) major problem in psychology. (Though there are several who awe us with their "cleverness" -- and apparent detailed 'thought' (e.g. like "by analogy" or borrowing a full model from another field. LOL).)
By the way, in other sciences the BIG QUESTION _can_ be answered, because at each critical (conceptual change) point, ONE CAN ACTUALLY ASK?: what's your direct observable replicable evidence. AND, IN ANY GOOD SCIENCE, these questions INDEED CAN BE, AND ARE, ANSWERED (there are citable empirical directly observable reliable reasonable PROXIMATE causes for all, at each step). Psychologists, pay attention: that is what real science is like. STUDENTS, beware: You cannot continue to accept "the basic research is still being done" and "this is a complicated topic" FOR DECADES -- you settling for what may very much in crucial ways be complete B.S.. (Too much use of the word "complex" or "complicated" very often indicates confusion -- not anything like deep knowledge, which you still wait to understand.)
I propose a way to approach understanding cognitive development that, as clearly outlined, DOES (and will, at each step) allow for some key directly observable proximate causes "FOR EVERYTHING". It is a good process, and TOTALLY IN-LINE WITH what we know about the Memories (demonstrably, at each step -- no matter how a reasonable questioner "divides" things [(concepts, explanations)] UP). See: Article A Human Ethogram: Its Scientific Acceptability and Importanc...
It is clearly a core cognitive-developmental approach with as much direct empirical foundation imaginable. Take it, or use your "models" -- and stagnate, with PSYCHOLOGY AS AN INFANT "SCIENCE" (at best).
