Document Summary
Was trained as a biologist (expert on mollusks); worked part-time with kids at the binet institute (developing new iq test) would later become the stanford-binet iq test. Kids" mistakes on a reasoning tasks revealed how cognitive abilities develop. Sensory motor stage (0-2 years) at this stage infant cannot represent objects in thought. They can only respond to what they see, hear, and touch. They lack a sense of object permanence. (objects continue to exist when they cannot be seen). By the end of the sensory motor stage, children start to understand object permanence. Pre-operational stage (2-7) early in this stage, children start to use language. They start to learn that words represent objects. Their understanding of concepts is weak (abstract ideas about what a group of objects has in common). They tend to rely on one property to define concepts (i. e. if a has 4 legs, and b has 4 legs, they must be the same).
