Analyze the following research scenario:

A cognitive psychologist investigates whether background noise affects reading comprehension. She recruits 40 undergraduate students and randomly assigns them to read a short article either in a quiet room or in a room with a loud lawnmower running outside. Afterwards, all participants complete a 10-item reading comprehension quiz. During the study, the researcher ensures that both rooms have identical lighting (standard fluorescent bulbs) and the same ambient temperature (72 degrees Fahrenheit). However, she notices that the participants in the loud room completed their quizzes in the afternoon, while those in the quiet room completed theirs in the morning.

Match each specific component of this study with its correct methodological classification.
