Jean Piagetâ€™s Theory of Formal Reason has been widely, used and accepted in the field of psychology. Although many other psychologists have criticized Piagetâ€™s Theory of Formal Reasoning and his Stages of Cognitive Development, it has also served as a foundation for others to build on. The Theory of formal reason works like a guideline to help us understand the cognitive development of infants throughout adolescents and even, to some extent, adults. Jean Piagetâ€™s Pendulum Study is one of the most straightforward methods that demonstrate how formal reasoning is measured. The purpose of this study is not only, as a student, to practice researching and analyzing data but it also serves to help gain practical experiencing conducting a study and relating it to the presented theory of formal reasoning. In this paper, I have taken four individuals, two adults and two early adolescents and have mimicked Piagetâ€™s pendulum study to see if his findings can be replicated.
In the Oscillation of the Pendulum and Operations of exclusion Study, presented in reading 7 of the reading file an outline of the Stages of Formal Reasoning is shown. (Athabasca University, 2001). They begin with stage 1: Indifferentiation between the subject own actions and the motion if the Pendulum. This preoperational stage is characterized by the subjectâ€™s failure to separate physical actions from mental operations. Therefore a great deal of their observations in regards to this particular study will be communicated as a direct result of their physical relationship with the object or pendulum This stage is also seen is young children likely under the age of eight. Stage two: The Appearance of Serial Ordering and Correspondences but Without Separation of Variables. Often seen in older school age children to pre-adolescence these Individuals can list and order factors that think are involved in the motion of the pendulum but wil
