Quizplus · Accepted Answer

Infants in Substage 5, also known as the tertiary circular reactions stage, repeat behaviors with variations as they explore and experiment with objects and their surroundings. They may engage in trial-and-error behavior to discover new ways of achieving their goals. They also have increased curiosity and interest in novel objects and situations. However, they do not have the cognitive ability to arrive at solutions to problems suddenly.
