HP101

today's HP101 lecture- Memory.

another interesting and exciting lecture.

our lecturer, also my tutor, Dr Cha, did many little experiments with us in LT today.

there are three key processes of Memory: Encoding, Storage and Retrieval. on the part of encoding, he asked "what is on the flip side of our $5 bill?" one student said "tree." another said "i think it's children, buildings, ppl playing some sports." haha. answer is it's a heritage tree found in Botanical Gardens, and this tree is in the bill because this tree holds many fond memories of our grandparents' when they were young. lesson learnt- we do not remember because we never pay attention to it.

visually, we are able to remember 7 plus/minus 2 items. this is the iconic memory (subset of Sensory memory). he flashed 7 alphabets in like one-over-twenty second, and we were asked to recall what we saw. surprisingly, we got the 7 alphabets right. next he flashed 16 alphabets. we were asked to recall again. this time, we could not get many right. so cool. last attempt, he flashed:

NUSNTUSMUSIMUSNW

we all got it right. haha. our brain is wonderful. we just did chunking. grouping of words together. this is what experts do. research showed that chess experts were able to better remember the chess pieces at their right positions when the pieces were put in a meaningful way. but when the chess pieces were not put in a meaningful manner, chances are, a less experienced chess player could remember better than the expert. this is because the expert is more familiar in this domain, and they rmb by chunking, relying on schema, forming meanings out of these chunks, so when the pieces were placed out of order, they found it harder to remember.

there were lots more of stuffs that he did with us, showed us. heh heh. back to doing blk 48 design.
