Experimental stimuli from Schulz & Bonawitz (2007). When both levers were pressed simultaneously, two puppets (a straw pompom and a chick) emerged from the center of the box. In this confounded case, the evidence was not informative about which of the two levers caused each puppet to rise. In the unconfounded conditions, one lever was pressed at a time, making it clear which lever caused each puppet to rise. During a free-play period following the toy's demonstration, children played more with the toy when the demonstrated evidence was confounded.
