learning & memory

(1) sensory memory ---> (2) short term memory ---> (3) long term memory

Any thing we encounter in our daily life, any info traces from our surroundings, or whatever our lecturer said in class is first considered as (1). Can only be encoded into (2) through ATTENTION. (so pay attention!) Without it, (1) can only lasts for 0.3-0.5 secs. And ability to sustain attention can be achieved by making an EFFORT. What's more, (2) also doesn't last long, which is only for 10-15 secs. The consolidation process by the brain to shift (2) to (3) is via REHEARSAL. (so, rehearse wut we've learnt in class i.e recall!) And Atkinson 1968 says, items can only enter (3) via (2)..so we cn only remember things in longer term if we rehearse them often. kan? n as expected, our long term memory has UNLIMITED STORAGE CAPACITY.

n some says sleep improves memory? well it's more evident in procedural memory rather than factual type of memory so i guess whoever uses their buku sejarah spm as bedtime story book (like me) last time was in fact a bit pointless..(unless ur point of doing so ws to help u fall asleep faster).

on the other hand, the 2 amines norepinephrine and dopamine are highly correlated to attentional or motivational state at the time of learning. (i think i shud consider searching for those 2 in tablets nw..ada ke eyh?haha) And cholinergic activity eg ACh in hippocampus is also very importnt in learning. it's already proven that Cholinesterase inhibitor (physostigmine) gives above-normal result in memory retrieval experiment. (ada jual dipasarankah? :p)

To wrap-up, doa, usaha, ikhtiar and tawakkal lah.
Sungguh, Allah mencintai org2 yg bertawakkal.

Selamat ber-exam!~ (^_^)
