Undergraduate research participant pools play an essential role in facilitating research, and many universities rely on them for participant recruitment. There is an abundance of information about those who do elect to participate in research through these recruitment systems but very little about those who do not. The present study examines both undergraduate research pool participants and nonparticipants, and the objective is to explore how they differ in their views. A sample of 483 Canadian undergraduate students (n = 442 participants and n = 41 nonparticipants) completed measures of their impressions of participation, their perceived enjoyment, and their knowledge gained from participating in research and asked to compare this with their impressions of attending class and taking exams. Factorial analysis of variance and ² results found support for both similarities and differences between both groups. Overall, the results suggest that nonparticipants do not have a good understanding of what is involved in participating in research activities and view it is a potentially aversive or negative experience.
