Roddy Roediger (2004):

“Most of the people participating in psychology experiments are college students. We get a lot of grief about this, I know, and we often feel abashed and ashamed. I don’t know why. All scientists use samples and techniques that are readily available and can be adapted to make rapid scientific progress. I study human memory, and to me the college student is the ideal experimental animal. Millions of years of evolution have designed a creature that is a learning and memorizing marvel. Students in my experiments have also been carefully selected through 12 or more years of education before they get to my lab. Only the ones who have shown, year after year, that they can learn and remember material in courses make it to my experiments. The world could not have arranged a more ideal subject,. . . ”
