Alistair conducted a laboratory experiment to investigate the effect of acoustic versus semantic encoding on short-term memory recall. He used a repeated measures design where 15 undergraduate students recalled a list of acoustically similar words, and then immediately afterward, recalled a list of semantically similar words. Alistair used the exact same 15 words for both conditions.
Explain one way in which Alistair could have improved this investigation.
