Piaget's theory of cognitive development, Erikson's theory of psychosocial development, and Kohlberg's theory of moral development are three distinct psychological theories. Here is a comparative table to help you compare and contrast the three theories:
| Theory | Piaget's Theory | Erikson's Theory | Kohlberg's Theory |
|-------|-----------------|-----------------|------------------|
| Focus | Cognitive Development | Psychosocial Development | Moral Development |
| Level of Development | Sensory-Motor, Preoperational, Concrete Operational, Formal Operational | Trust vs. Mistrust, Autonomy vs. Shame & Doubt, Initiative vs. Guilt, Industry vs. Inferiority, Identity vs. Role Confusion, Intimacy vs. Isolation, Generativity vs. Stagnation, Ego Integrity vs. Despair | Preconventional, Conventional, Postconventional |
| Age Range | 0-7 | 0-19 | 5-18 |
| Key Concepts | Schemas, Assimilation, Accommodation, Equilibration | Identity, Role, Intimacy | Moral Reasoning |
Piaget's theory of cognitive development focuses on how children acquire and develop knowledge, while Erikson's theory of psychosocial development focuses on how individuals develop social and emotional skills throughout their life. Kohlberg's theory of moral development focuses on how individuals develop their sense of right and wrong.
Piaget's theory is divided into four stages of development: Sensory-Motor, Preoperational, Concrete Operational, and Formal Operational. Erikson's theory is divided into eight stages of development: Trust vs. Mistrust, Autonomy vs. Shame & Doubt, Initiative vs. Guilt, Industry vs. Inferiority, Identity vs. Role Confusion, Intimacy vs. Isolation, Generativity vs. Stagnation, and Ego Integrity vs. Despair. Kohlberg's theory is divided into three stages of development: Preconventional, Conventional, and Postconventional.
Piaget's theory applies to children aged 0-7, Erikson's theory applies to individuals aged 0-19, and Kohlberg's theory applies to individuals aged 5-18. Key concepts within Piaget's theory include schemas, assimilation, accommodation, and equilibration. Key concepts within Erikson's theory include identity, role, and intimacy. Key concepts within Kohlberg's theory include moral reasoning.
In conclusion, Piaget's theory of cognitive development, Erikson's theory of psychosocial development, and Kohlberg's theory of moral development are three distinct psychological theories that focus on different aspects of development and apply to different age ranges.
