Jean Piaget was a psychologist who developed a theory that children went through four stages of cognitive development. In his theory, the second stage was known as the preoperational period dealing with ages two to seven years old. Piaget stated that young children were symbolic thinkers and that they didn’t think logically compared to older children. They couldn’t understand the world by actions and perception but merely focused on objects and events that occurred (Bjorklund & Hernandez-Blasi, 2012). At this stage, Piaget generated the idea of conservation which is what he stated young children lacked.

They hypothesis that conservation difficulties may relate to how much the specific language impairments relied on the external features of the task compare to their cognitive thinking. They stated that children with specific language impairments focused less on their internal knowledge and more on their external features which causes them to have a slow grasp on the concept of conservation (Mainela-Arnold et al., …show more content…
They focused more on the role of location, age, and gender differences. They hypothesize what was the connection between individual factors with a geographical location, such as urban and rural on conservation achievement of children on the different conservation tasks (Assan & Sarfo, 2015). To test their hypothesis, they had a participant of one hundred and twenty children between the ages of four to six. Each child was given four different conservation task. For each question that was responded correctly, the child was given a point, the amount of point was added to obtain the total conservation score. The kids that scored three points or higher were considered good conservers, the ones that scored two points were considered moderate conservers and the one that scored below two were considered non-conservers (Assan & Sarfo, 2015).
All of the results were later compared to the location of children rural vs urban, age vs age, and finally gender vs gender. Assan and Sarfo (2015) found that there were no significant difference between urban and rural children or between females and males. They also stated that there wasn’t a significant difference between the younger children and older children. Assan and Sarfo (2015) stated that based off their results the only significant finding was that the older children did better with the conservation of liquid compared to the younger
