Question

What is the capacity of short-term memory (STM) according to George Miller's theory?

• A. Unlimited
• B. 7±2 items
• C. 15-30 items
• D. 50-100 items

Answer 1

Answer:

B. 7±2 items

According to George Miller's theory, short-term memory (STM) has a limited capacity of 7±2 items. STM retains information for about 15–30 seconds unless rehearsed. Information that receives attention moves from sensory memory to STM, which can also process new information along with retrieved knowledge from long-term memory (Working Memory).
