Jean Piaget (1896-1980) was actually not a psychologist at first; he dedicated his time to mollusc research. In fact, by the time he was 21 he’d already published twenty scientific papers on them! He soon moved to Paris, and got a job interviewing mental patients. Before long, he was working for Alfred Binet, and refining Burt’s reasoning test. During his time working at Binet’s lab, he studied the way that children reasoned. After two years of working with children, Piaget finally realised what he wanted to investigate – children’s development! He noticed that children of a younger aged answered questions qualitatively different than those of an older age. This suggested to him that younger children were not less knowledgeable, but gave different answers because they thought differently.
Background:
Piaget’s theory is based on stages, whereby each stage represents a qualitatively different type of thinking. Children in stage one cannot think the same as children in stage 2, 3 or 4 etc. Transitions from one stage to another are generally very fast, and the stages always follow an invariant sequence. Another important characteristic of his stage theory is that they are universal; the stages will work for everyone in the world regardless of their differences (except their age, of course, which is what the stages are based on!)
Piaget acknowledged that there is an interaction between a child and the environment, and this is a focal point for his theory. He believed a child cannot learn unless they are constantly interacting with their environment, making mistakes and then learning from them. He defined children as “lone scientists”; he did not identify any need for teachers or adults in cognitive development. Children have all the cognitive mechanisms to learn on their own, and the interaction with their environment allows them to do so
