“…For example, Raddick et al [2010] identified 12 motivations for participating in the Galaxy Zoo project, including contributiing to a science project, learning about astronomy, discovery of galaxies few people have seen, community (i.e., meeting people with similar interests), teaching (i.e., useful resource teaching others about astronomy), the beauty of galaxies, finding the work fun, vastness of space (i.e., enjoying considering the scale of the universe), helping (i.e., happy to help), the Zoo (i.e., interest in the Galaxy Zoo project), and astronomy and science (i.e., having general interest in the field). Curtis [2015] identified a similar set of motivations for the Foldit project, including contribution to science, background interest in science, intellectual challenge, curiosity, liking puzzles, liking computer games, to learn something new, friendly competition, visual appeal/aesthetics and relaxing. Reed et al [2013] identified three broader motives, social engagement, interaction with the website and helping.…”
