It is a stage in which the infant can, in addition to mimicking certain reactions and movements, coordinate movements and reactions in order to achieve a specific goal. So it begins to be oriented toward a specific goal, not only repeating the movements seen, but coordinating and taking the initiative to reach the desired goal.
