CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -The Magic number 7 (plus or minus two) provides evidence for the capacity of short term memory. 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.

Detailed explanation-2: -It is often interpreted to argue that the number of objects an average human can hold in short-term memory is 7 ± 2. This has occasionally been referred to as Miller’s law.

Detailed explanation-3: -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-4: -(Working memory) It holds only a few items (research shows a range of 7 +/-2 items) and only lasts for about 20 seconds.

Detailed explanation-5: -The duration of short-term memory (absent rehearsal or active maintenance) is estimated to be on the order of seconds. The commonly cited capacity of 7 items, found in Miller’s Law, has been superseded by 4±1 items. In contrast, long-term memory holds information indefinitely.
