CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -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-2: -Short-Term Memory: Up to 7 Items, But Highly Volatile. Many psychology experiments have shown that our short-term memory can hold only a limited number of separate items. The average is about 7 items, plus or minus 2, depending on the individual.

Detailed explanation-3: -Short-term memory can hold approximately 7 bits of information for around 20 seconds. Information here is either forgotten, or it is encoded into long-term memory through the process of rehearsal. Long-term memory is the permanent storage of information-its capacity is basically unlimited.

Detailed explanation-4: -Short-term working memory relies most heavily on the prefrontal cortex.

Detailed explanation-5: -The magic number seven is the number of chunks of information a person can hold in working memory at the same time. A chunk is a unit of some kind. It could be a letter, a word, or a short sentence. Miller examined short-term memory tasks and found that typical subjects could hold about 7 chunks in memory at once.
