Zelazo and colleagues (1996) showed three-year-old children a set of cards that varied on two dimensions: shape and color. Children were first told to sort the cards based on color. Children did that easily
Then, children were told to start sorting the cards based on shape. After the switch, children continued to sort on the basis of color, even though they knew they were supposed to sort based on shape. A typical five-year-old would have no difficulties making the switch. The difference between three- and five-year-old children's performance on this task is likely due to differences in the ability to ___. a. associate one stimulus with another b. recognize a familiar stimulus c. inhibit a response d. process information quickly
