In this test the kids are sorting figures that do or don't activate a music box. The box is left next to them so they could use the box to test the figures prior to sorting them or they could rely on what an experimenter told them (white figures activate the box) or what they observed when a different experimenter was actually using the toy. What the title means by "seek data" is "Did the kids try the figurines on the box themselves?"
