Sample triads for the Dimension-Preference task (DP). Each triad is composed of the target object (top item), and two choices (bottom items) from which children were instructed to choose the item that was “most like” the target object. In the preference Test trials, each choice object matches the target object along one dimension (e.g., the target object, a red circle (dark) matches one choice object, a red cross (dark) in color and the other, a blue circle (light) in shape). In the Priming trials, only one choice matches the target object along a single dimension (color or shape). Children were presented with two priming trials that primed the same dimension (either two Color priming trials or two Shape priming trials), then were presented with ten Test trials. The relevant measure of interest is children’s choice during the Test trials when primed with either color or shape.
