The authors use Piaget’s theory to address the problem by breaking down the sensorimotor period into multiple sub-stages and Piaget argues that the physiological approach is useful. In my opinion the author is very successful in making their case. Piaget’s cognitive developmental theory is used to support their case. His theory began in the search of how children develop their knowledge. Piaget designed a method which was used to observe the ways children respond and communicate in certain situations with their own thoughts as a way to examine the thought process. Neuroscience hasn’t focused on the development at an early age. Therefore, the authors emphasize Piaget’s sensorimotor period. “Piaget (1973) stated that ‘…in order to reach a certain stage, previous steps must be taken… thus we reach a hierarchy of mental structures which are built in a certain order of integration,”(Lefmann, 641). For example, if a child was seven years old and tried to do a multiplication question when they only have the knowledge to carry out addition and subtraction questions, they will struggle to complete a question this …show more content…
Piaget came up with multiple sub-stages for the sensorimotor by creating certain situations and seeing how his children responded. During the first sub-stage Jean found that children learn through their senses; such as following moving objects or closing the hand when it makes contact with an object. The second sub-stage focuses on repetition; when a child sucks on their thumb it is now by coordination. In the third stage, children learn that they can take a particular action and it will cause a certain effect. Throughout the fourth sub-stage, the child’s neuromuscular functioning improves and they have the ability to plot and carry out certain movements to get exactly what they want. The understanding of object permanence is key in the fifth sub-stage. The child begins to understand that even though an object isn’t in reach or visible, they know the object still exists. Resulting in a major cognitive breakthrough for the child. The final sub-stage emphasizes on a child’s
