38. Jean Piaget (pee-ah-ZHAY)
Developmental psychologist who introduced a stage theory of cognitive development

From birth to about age two
Child gathers information about the world through senses and motor functions
Child learns object permanence

40. “Out of sight, out of mind”
Object Permanence

The properties can include mass, volume, and numbers.
