A friend’s uncle, who lives in the area, has a set of fraternal male twins named Justin and Christian that just a week ago, turned four years old. And after getting a good connection through my friend, I was invited over to do a few of Piaget’s experiments on each of the boys. Being twins, both boys obviously fit into the preschool age-range and I determined that I should test their preoperational thought as it relates to their conservation, centration, and the irreversibility they may feature in their thinking. Piaget argues that adolescents still in the stage of preoperational thinking focus on one aspect of a situation, neglecting its other important features, which is called “centration” (Berk, 2012). They also have an inability to mentally go through a series of steps in a problem, and then reverse direction, returning to the starting point. This is called “irreversibility” (Berk, 2012, p. 322). These factors relate to a children’s lack of ability in “conservation” where an object’s physical characteristics remain the same, even when their outward appearance undergoes change (Berk, 2012). I chose to test these factors and limitations in these preschoolers to see if Piaget’s theory holds true in both subjects.…
