Name of a theory discussing how what can ideally/efficiently be taken from a piece of content depends on current knowledge? Similar to zones of proximal development.

I stumbled across an article discussing this awhile ago but can't for the life of me find it again, or even what it was, exactly.

To oversimplify it, if we treat all knowledge that exists as being contained in a large sphere, and our current level of knowledge as a smaller sphere inside the larger one.

When engaging with a piece of content, there are lots of things that could be focused on, but just beyond the boundaries of our current knowledge is a sweet spot/band of knowledge that can be particularly effortlessly acquired. Even if we are able to grasp onto somehow far beyond the bounds of our sphere, it'll be difficult to hold onto (or we'll recall it in a limited fashion) because it's too many steps away from our current level of knowledge and not grounded in anything.

An important takeaway from this is that what we can take from a given piece of content will change over time, so we should expect to revisit content and, each time we do, to slightly re-adjust our sights.

(It seems like it may be related to Stephen Krashen's hypotheses on comprehensible input)
