Preoperational Stage (2-7 years) • Can use words, images, and symbols immaturely • Use imagination • Egocentrism (inability to see things from another's point of view • Can't focus on two things at once
Preoperational (Cont.) • Don't get the idea of conservation: the realization that properties of objects remain the same even if their shape changes.
Concrete Operational (7-11 years) • Logic used, but only in context of tangible objects and events. • Cannot think in abstracts or hypotheticals. • Thinking limited to personal experiences and actual events.
