The Sensorimotor Stage

Piaget’s Ideas
Jean Piaget’s ideas regarding how a child develops has had an enormous influence on our views upon babies and children. Piaget (1896-1980) was a biologist and developmental psychologist and research have proved some of his initial ideas regarding developmental stages to be too rigid.  
  • Many children can solve some of the problems earlier than Piaget suggested.
Nevertheless, Piaget’s views upon children and development are interesting. They provide you with several ideas about how to look and study your own child’s ways of interacting and learning about the world.
 
Constructing the World
Piaget believed that children construct their own knowledge, and that every child follows the same developmental stages. Piaget suggested four different developmental stages – 
  • Sensori-motor (birth -2 years)
  • Preoperational (2-7 years)
  • Concrete operational (7-11 years)
  • Formal operational (11 years and up)
Development of Thinking
Piaget was interested in the development of thinking, and he acknowledged the importance of emotions. But his theory does not describe the emotional development. However, this should not be taken as sign that Piaget did not consider it important. 
  • Piaget sees the child as active in development, “a little scientist” constructing and creating interaction with the environment that lead to development.  
Genes and the environment are working together to influence development. The starting point is basic actions called sensorimotor schemes, and the baby build on this foundation through interacting with the environment. As a child matures or grows up, his capacity to understand the world increases. According to Piaget, a child cannot solve a task until he is psychologically mature enough. Development is not a smooth process, or a continuous process, instead there are certain critical points where a new insight or capability to understand the world matures. A child has to overcome limits of the previous stage to solve the task of the next stage. There are cognitive barriers that a child has to pass through and new abilities needs to be acquired. A genuine qualitative shift.
 
Research has suggested that children can solve Piagetian tasks at an earlier stage and this indicates that cognitive abilities may develop gradually. Piaget, as a biologist, was influenced by Darwin’s theory of evolution. Piaget saw the development of intelligence as an adaptation. Thus, the social aspect of development was not a priority and the role of teachers and influences of the environment is not studied or included in his theory.
 
Sensorimotor – Birth -2 years
The word “sensori “ means that it has to do with senses, and “motor” has to do with motor abilities such as hands and actions. This period is characterised by an enormous development that may be overlooked since a baby cannot verbally describe his thoughts and actions.
  • The baby interacts with the environment through his actions. 
During the last decades, this period has attracted researchers’ attention. Several new ideas related to both reflexes and what an infant can do has been suggested.
 
Newborn – 2 months
  • A newborn infant has according to Piaget no idea of “self” rather they act and discover the world outside the womb by using reflexes. 
  • A reflex is a natural physical response and many of the reflexes that a baby is born with disappear with a couple of months as the baby matures. 
  • An infant is born with reflexes such as the sucking reflex, rooting reflex and gripping reflex.
 
The first six to eight week an infant explores the world by co-ordination of action through reflexive behaviours. Explore the world mainly by using sucking, looking, listening, and grasping. 
  • Infants explore objects in the mouth by using the sucking reflex. 
The flexing of the fingers when something tickles the palm develops during the first weeks to an intentional grasping. 
 
If you place your finger into your baby’s open palm, he will grasp it and the grip will get stronger if you try to pull away.

2-4 months   
  •  An infant begins repeat an event that initially happened by chance. And may wave his hand in front of his face. 
  • The infant’s body is still the focus of actions and attention.
You can watch a baby opening and losing their fingers over and over again. Like a little gymnast practicing an action.
 
4-8 months 
  • The infant repeats actions that are fun, and interesting. 
  • Actions that have a pleasurable result may develop into habits. 
  • The co-ordination between vision and hand movement is developing.
You can watch a baby intentionally grasp in the air for a mobile that is hanging above the bed. Babies often use their feet to kick the mobile. A four-month old baby may start to slap his hands in the water when he is having a bath. And he may start to wave a little rattle or other small toys in his hands. A couple of weeks later, the baby has a firm grip and can hold a small toy in his hand.
  • A six-months-old uses both hands and can pass a toy from one hand to the other. 
  • This stage is important, actions become more purposeful, and it is according to Piaget the beginning of logic.
  • A baby may pick up a toy to play. He explores the toy by putting it in his mouth.
 

8-12 months 
  • The co-ordination of hand-eye continues to develop. A baby beings to deliberately plan step to reach a goal. 
  • A baby may reach behind a screen to obtain a hidden object. 
  • Picks up a rattle with the intention of making a noise.
12-18 months  
Babies are fascinated by things when they can change the outcome. The love toys and they are continually experimenting with new behaviour. 
  • Piaget described this stage as the real starting point for the “young scientist”.
  • The child is trying to figure out how things work by using new ways to meet challenges.
Instead of walking towards a toy may try to pull a blanket towards him to get a toy that is placed on it. A toddler may try to gets his parents’ attention by trying different sounds and actions.
 
 
18-24 months 
Now, your toddler begins to use symbols and form mental representations.
  • Insight into how things work and creativity is beginning to emerge. Discovering the intentions behind actions. 
  • A toddler understands the world not only through his actions but also through his thinking.
