Final answer:
Short-term memory capacity can be improved through chunking, which involves organizing information into smaller chunks for easier recall.
Step-by-step explanation:
Miller (1956) reviewed findings on the digit span test and found that short-term memory capacity is limited to between 5 and 9 numbers, which is referred to as the 'magical seven, plus or minus two.' However, through the use of chunking, we can improve the span of our short-term memory. Chunking is the process of organizing information into smaller, more manageable chunks. For example, instead of trying to remember the number 5205550467, you can chunk it as 520-555-0467, which is easier to remember.
