Child researchers seek low-income subjects - baltimoresun.com: Roughly 13 minutes into a science experiment involving sets of blocks, Dorian Larkins, who at that moment is two weeks shy of his third birthday, has had enough. He would rather play with the trains in the waiting room, and he says he has to pee.
But at his mother's urging, he soldiers on for another five minutes or so until the session, which looks at toddler memory, wraps up. His mom believes it's imperative that Dorian participate in the work of the Laboratory for Child Development at Johns Hopkins University — but less so for her son's sake than for the researcher's.
"Being an African-American child, it's really important to have him in the study, to have some diversity," said Mona Larkins, 42.
