A student conducted a cognitive psychology investigation into the effect of acoustic similarity on short-term memory recall. They recruited an opportunity sample of 12 friends, read aloud a list of acoustically similar words (e.g., cat, cab, can) at 1-second intervals, and asked them to write down the words in order immediately after hearing them.
Explain two improvements that could be made to this cognitive psychology investigation.
