Human brain recalls visual features in reverse order than it detects them

New research has contributed to solving a paradox of perception, literally upending models of how the brain constructs interpretations of the outside world. When observing a scene, the brain first processes details — spots, lines and simple shapes — and uses that information to build internal representations of more complex objects, like cars and people. But during recall, the brain remembers those larger concepts first.

This makes perfect sense. I don’t doubt that they are right.

But it’s hard to prove and I’m not sure that their method is completely adequate.

A much clearer example would be found in music. The same logic would be that when a person hears two notes of different pitches, they remember the change in pitch more accurately than the pitches themselves. That is so darn obvious that it hardly needs stating. So to claim that “traditional models predict” that many people would falsely remember the lower pitch to be higher than the higher pitch seems off.

Oops. I just made an ass of myself there. Or did I? Would people who are tone deaf still remember change in pitch better than pitch itself? Perhaps so, it would be worth a test.

Anyway, my point being that what the test shows is that people tend to use the more accurate method to remember things, not necessarily the most recent. They are claiming that people remember the most recent first, but their test method doesn’t distinguish between “most recent first” and “most accurate first”.

Is that because those larger concepts are complete when recalled and their is no need to reprocess it like when its first seen

So our brain caches images/scenes/etc so it doesn’t have to rebuild them from scratch each time ?
Makes senses as it’s efficient and requires less processing.
All we need now is CC cleaner for our brains

Heh!

You got it!

:)

Makes sense, once the lines and shapes have been resolved to be a car it is easier to remember a car and maybe it’s type and colour than go through recalling the lines and shapes a second time to resolve it to a car, a process you have already done.

LIFO… like a stack.

It is commonly accepted in the music world (though I don’t buy it) that most people do not have perfect pitch, only relative pitch.

not sure the idea is so new, revolutionary, or that examples in common experience don’t abound that detract from it being new.

but, it is the _new_s.

Makes sense, FILO
