A psychologist investigates whether reading information aloud improves recall. Each participant receives the same sheet containing 12 science facts. Participants in the reading-aloud condition have four minutes to study the sheet, while participants in the silent-reading condition have two minutes. Everyone then has two minutes to write down as many of the facts as they can remember.
State one problem with the procedure used in this investigation.
Explain how this problem could reduce the validity of the findings.
