The phrase "seven, plus or minus two" refers to the capacity of short-term memory.

Explanation:

Short term memory is also called as active memory or primary memory and refers to the information that we are currently thinking of. It generally lasts for short time of few seconds (20 seconds to 30 seconds) and are erased if not rehearsed time and again. Short term memory store up to 'seven', plus or minus two words at a time.In 1956, Miller performed an experiment and put forward the idea that 'short term memory' can store 5 to 9 items, but modern theory suggests that the information in 'short term memory' can be increased if the information are chunked together.
