(03.05 MC)Dr. Marshall recruited 150 undergraduate students enrolled in psychology courses at his university for his study. Participation was voluntary, and students received extra credit for their involvement. Participants watched a video clip of a simulated traffic accident. Participants were randomly divided into two groups. The experimental group received a questionnaire containing misleading questions, such as, “How fast was the car going when it ran the stop sign?” (when there was no stop sign). The control group received a neutral questionnaire with no misleading information. Five days later, all participants completed a memory test that assessed their recall of details from the video. Questions focused on critical elements that had been the focus of the misleading questions. Results indicated that participants in the experimental group were more likely to report false memories as compared to the control group.What type of sample is used in this study?
