Dr. Vance conducted a laboratory experiment to investigate the capacity of the phonological loop using the word length effect.
In the first condition, participants were presented with visual lists of five monosyllabic words (e.g., 'bond, yield, fund, debt, cash') and asked to write them down in the correct serial order immediately after presentation.
In the second condition, the same participants were presented with visual lists of five polysyllabic words of equal frequency (e.g., 'depreciation, capitalization, hyperinflation, collateralization, securitization') and asked to perform the same serial recall task.
Dr. Vance implemented a repeated measures design.
Explain one strength and one weakness of using a repeated measures design in this study.
