In February 2005, a report by CBS News' "60 Minutes II" raised questions about whether Marla created the paintings on her own. "60 Minutes" enlisted the help of Ellen Winner, a child psychologist who studies cognition in the arts and gifted children. Winner was impressed with Marla's work, and indicated that Marla was the first child prodigy she'd seen paint abstractly. The Olmsteads agreed to permit CBS crews to set up a hidden camera in their home to tape their daughter painting a single piece in five hours over the course of a month. When Winner reviewed the tapes, the psychologist said, "I saw no evidence that she was a child prodigy in painting. I saw a normal, charming, adorable child painting the way preschool children paint, except that she had a coach who kept her going." Winner also indicated that the painting created after CBS's hidden camera looked "less polished than some of Marla's previous works."
