CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -It was written by the cognitive psychologist George A. Miller of Harvard University’s Department of Psychology and published in 1956 in Psychological Review. It is often interpreted to argue that the number of objects an average human can hold in short-term memory is 7 ± 2.

Detailed explanation-2: -Most adults can store between 5 and 9 items in their short-term memory. This idea was put forward by Miller (1956) and he called it the magic number 7. He though that short term memory could hold 7 (plus or minus 2 items) because it only had a certain number of “slots” in which items could be stored.

Detailed explanation-3: -Miller’s Law predicts that the average person can only keep 7 (± 2) items in their working memory. History. In 1956, a psychologist, George Miller performed research in which he found what he believed to be the limit of the human ability for processing information.

Detailed explanation-4: -So, not all groups of four objects are created equal: The brain can indeed remember up to four things, but it does best when those things are spaced out into two on the right side and two on the left. Any more than two on one side, and working memory starts to break down.

Detailed explanation-5: -As a sentence or a string of numbers gets longer, it becomes exponentially harder for the excited cluster to suppress the others from firing, resulting in pathways that are weak or barely there. Recalling seven items requires about 15 times the suppression needed to recall three.
