一個資訊的單位是什麼??????
Whereas most adults can repeat about seven digits in correct order, some individuals have shown impressive enlargements of their digit span - up to 80 digits. This feat is possible by extensive training on an encoding strategy by which the digits in a list are grouped (usually in groups of three to five) and these groups are encoded as
a single unit (a chunk).
還有更小的單位bits????
chunks can vary dramatically in how many bits they carry: a sequence like "1 0 0 1 0 1 1" consists of seven chunks worth seven bits - less than a single word, which is just one chunk
短時間記憶大多為三到四個資訊
Cowan (2001) has proposed that
working memory has a capacity of about four chunks in young adults (and fewer in children and old adults).

The capacity of short term memory is approximately 7 "chunks."
A CHUNK is a meaningful unit of information.
To make your learning more effective, practice "chunking" and try not to work with more than seven chunks at a time.
