Elena decided to investigate the effect of acoustic similarity on short-term memory recall. She conducted a laboratory experiment where one group of participants was presented with a list of 20 acoustically similar words (such as map, mad, man) and another group was presented with a list of 20 acoustically dissimilar words (such as pen, day, cup). Elena then asked the participants to immediately recall as many words as they could.
