Number of rule violations(i.e., moving more than one disk at a time or placing a larger disk on top of a smaller one); They are instructed to build a tower using a few moves as possible. They are given two rules to follow: They can move only one piece at a time using just one hand, and a larger disk may never be placed on top of a smaller disk. The first time a participant violates one of these rules, she or he is reminded of the rule, and the disk is returned to its last location. On subsequent violations of the same rule, the participant is simply told that she or he made an error, and the disk is returned to its last location.
