If you're reading this post, you are now blinking and breathing manually. You are also aware that your jaw has weight and must manually keep it closed.
Other stimuli going on around can cause you to react, or not react, depending on how important it is to you.
Here's part of a thesis I wrote about the effects of memory...
MY MEMORY, DRAWN AND QUARTERED
I've been trying to figure out how my memory works for more years than I'd like to count and finally came up with comprehensive answers that everyone should be able to relate with. This is all new. You won't find it in any book or scientific papers.
Feel free to debate, debunk, or draw and quarter me.
It breaks down into 5 different categories, Snapshots, Associative, Proactive, Reactive, and Emergency.
Snapshot Memories: Things you see, hear, taste, touch, or smell for a moment that click in your memory, has no particular meaning , and quickly disappears. Here is a representative list.
Sight: headline, sign, store, house, tree, flower, cafe, etc
Sound: horn, car, bus, train, mower, plane, laugh, etc.
Taste: coffee, water, coke, cocoa, beer, root beer, etc.
Touch: spoon, fork, knife, toothbrush, cup, glass, etc
Smell: coffee, parfume, body odor, flower, soap, etc
Associative Memory: Same as snapshot memories except that these have relevance, remind you of incidences or events from the past, but not enough stimulation to do anything about them.
Proactive Memory: Same as associative memory except that they stimulate anticipation of things to come... problems, needs, changes, plans to do things later on, and possible consequences if you do, etc..
Reactive Memory: Same as proactive memory except that they activate response... go to, reach for, say something, write a letter, walk, eat, drink, etc.
Emergency Memory ; Same as reactive memory except that they activate immediate reaction... Run, duck, jump, avoid, brake, defend, etc.
