• Classification and categorization• Less egocentric• Inability to reason abstractly or hypothetically• Can conserve• Can understand mathematical operations.
Formal Operational Stage (age 12 - adulthood)
• Abstract reasoning using imagined realities and symbols.
• Potential for mature moral reasoning.• Understanding of religion develops.• Can spot hypocrisy.
Typical Age Range
Description of Stage
Developmental Phenomena
Birth to nearly 2 years SensorimotorExperiencing the world through senses and actions (looking, touching, mouthing)
•Object permanence•Stranger anxiety
About 2 to 6 years
About 7 to 11 years
About 12 through adulthood
PreoperationalRepresenting things with words and images but lacking logical reasoning
•Pretend play•Egocentrism•Language development
Concrete operationalThinking logically about concrete events; grasping concrete analogies and performing arithmetical operations
•Conservation •Mathematical transformations
Formal operationalAbstract reasoning
•Abstract logic•Potential for moral reasoning
Piaget’s Stages of Cognitive Development
Piaget’s Theory Challenged• New studies indicate infants do
more than sense and react• Receptive language is much
larger than previously believed.• One study had 1 month old
babies suck one of two pacifiers without ever seeing them
• When shown both pacifiers, infants stared more at the one they had felt in their mouth
• This requires a sort of reasoning

Erikson’s Stages of Psychosocial Development
Approximateage Stage Description of Task
Infancy Trust vs. mistrust If needs are dependably met, infants(1st year) develop a sense of basic trust.
Toddler Autonomy vs. shame Toddlers learn to exercise will and (2nd year) and doubt do things for themselves, or they
doubt their abilities.
Preschooler Initiative vs. guilt Preschoolers learn to initiate tasks(3-5 years) and carry out plans, or they feel
guilty about efforts to be independent.
Elementary Competence vs. Children learn the pleasure of applying(6 years- inferiority themselves to tasks, or they feel puberty) inferior.
