For the acquisition phase a target was set of 300 bubbles to be touched in the definition phase of the dexterity zone. There were 126 bubbles presented during each attempt; therefore it took at least three attempts to reach the proposed goal. Soon after the step establishing the dexterity zone, the researcher defined the central bubble and began the stage of chase area. In addition to the acquisition phase, all groups performed a retention test after 5 minutes with the completion of only one attempt. After the retention test, two transfer tests with the change of interfaces were performed.
