The aim of this essay is to briefly explain Piaget’s Stage Theory and evaluate its appropriateness for explaining how children develop mentally. His theory states that children develop in four different stages from the ages 0-12. There are varying sub-stages for these and each has its own description with experiments to test which stage an infant is in. Although Piaget is a credited theorist this particular theory is often criticised and this essay will explore the reasons for this as well as providing experimental evidence for the criticisms and for Piaget’s theory.
The first stage to Piaget’s theory is the Sensori-motor Stage which takes place between the ages of 0 and 2. There are 6 sub-stages categorised by age in months. At this point infants begin to focus on objects and put together a series of actions to achieve goal. They also need immediate sensory actions to understand a stimulus. Here the infants establish a minor sense of self as they learn to differentiate themselves from their environment (Smith, Cowie & Blades, 2015). In addition, in the beginning of this stage infants can only create motor reflexes but these develop more throughout the sensorimotor stage (Sandwell, 2015). This explains why infants are limited to certain actions and why their language skills are minimal near the end of this stage.
The Preoperational Stage begins at 2 years old and ends at 7 years old. It is in this stage that a child begins to learn how to classify objects by using language
