A cognitive psychologist conducts an experiment to investigate whether the format of educational material affects information retention. Group A studies a text about astrophysics presented in a traditional printed booklet, while Group B studies the identical text presented as an interactive tablet-based e-book. After exactly 30 minutes of study, both groups complete a 20-item multiple-choice comprehension test to measure retention.
