Jean Piaget CDEV 65 Class #7
Jean Piaget (1896-1980) Swiss Psychologist
Published his first research study at age 11!
Although he studied children, and wrote about them, he never developed a program
Original research on children was seen as flawed
Small sample size – only three children
They were his children!
Piaget’s experiments have been replicated over and over – the results are consistent (either he was incredibly smart, or incredibly lucky!)
Piaget’s Four Stages of Cognitive Development
Sensorimotor birth-2 years
Preoperational 2-7 years
Concrete Operational 7-11 years
Formal Operational 11 years
Sensorimotor (0-2 years) Absorbing information through the senses
Becoming mobile
Object permanence emerges – usually in the 7-9 month range
Object permanence means being able to form a mental image of something (or someone) even when that thing isn’t present
Before a child has object permanence, he will not notice when a particular toy is out of his space, as he cannot form a mental image of it if he cannot see it. This is a great example of the phrase “out of sight, out of mind”.
Once a child has developed object permanence he might notice when something is missing. For example, if his favorite toy isn’t in his space, he might go looking for it (assuming he has some mobility). If mom leaves the room, the child might get upset about her not being there.
When the child is upset by the departure of his “person”, this is called separation anxiety
Not all children develop separation anxiety
Preoperational (2-7 years) Language abilities are exploding!
Child is very egocentric – has a hard time seeing or recognizing others’ point of view
Child lacks conservation
Conservation is the ability to understand that something (volume/mass, number, weight, etc.) remains the same even if the appearance changes
There are videos on Canvas to demonstrate this concept
Fun fact: if you ask a 4 year old to “summarize” their favorite movie, it will take nearly as long as the actual movie for them to give you the summary!
Piaget used a number of tasks, including the ones shown here, to test children’s ability to judge whether certain characteristics of an object, such as its mass, change when the appearance of the object is changed through a simple transformation.
Piaget had an interesting way of studying egocentric thinking in young children using the three mountain task. The young child is shown a model display of three mountains on a table. A doll sits on the opposite side of the display, as shown in this figure. The child is then shown a series of drawings and is asked to choose the one that shows what she is looking at. Most children have difficulty doing this. The child is then asked to choose the drawing that illustrates what the doll is looking at. Many children will choose the drawing that they themselves are looking at, which illustrates how young children consider what they see to be what others see.
Concrete Operational (7-11 years) Child understands conservation
Can solve problems in a logical fashion (figures things out in his head)
Still very literal
Not quite ready for abstract thought
Formal Operational (11 years ) Child develops the ability to think abstractly
Ready for algebra!
Although adults are capable of Formal Operations, we use Concrete Operations most of the time!
Schemata, Assimilation, and Accommodation Schema (plural is schemata)
An idea of what something is
A child’s schema for cat might be: four legs, fur, and a tail
Assimilation
An existing schema is used to process new information
When a child sees something with four legs, fur, and a tail, their schema tells them it is a cat
Accommodation
When a child sees a dog, and it doesn’t exactly fit the schema for cat, an accommodation must be made
The accommodation results in the formation of a new schema
Equilibration Humans don’t like to be unbalanced; we like equilibrium (being balanced)
If new information doesn’t fit into an existing schema, we are faced with disequilibrium
We then make an accommodation (formation of the new schema) to regain a sense of equilibrium
Piaget believed… In providing a Responsive Environment
Environment is a teacher
A responsive environment asks questions of the children instead of always providing answers
Activities that get children wondering are a great way to create a responsive environment
For example, a pail of water and paint brushes. The children can “paint” the outside walls, fences, and ground. As the “paint” fades, they’ll wonder what happened.
Development is predictable and sequential
All children will go through the four stages of cognitive development in the same order, but not necessarily at the same speed
A good program is based on an understanding of child development
