Which of the following is not a stage of Piaget's theory of cognitive development?
Detailed Explanation
📌 Core Theoretical Concept:
Jean Piaget's theory of cognitive development is a foundational framework in developmental psychology. According to Piaget, children progress through four distinct stages of cognitive development: (1) Sensorimotor stage (birth to 2 years), (2) Preoperational stage (2 to 7 years), (3) Concrete operational stage (7 to 11 years), and (4) Formal operational stage (11 years and above). Among the given choices, the 'Latency stage' is not a part of Piaget's cognitive stages. Instead, the latency stage is the fourth stage of Sigmund Freud's psychosexual theory of development, lasting from around age 6 to puberty. Therefore, option (b) is the correct answer as it is extraneous to Piagetian theory.
📊 Key Exam Points:
- Piaget proposed exactly four cognitive development stages, excluding any latency stage.
- Option (a) Formal operational stage is Piaget's final stage, marked by abstract reasoning and hypothetical thinking.
- Option (c) Concrete operational stage is the third stage, characterized by logical operations regarding tangible objects.
- Option (d) Sensorimotor stage is the initial stage where infants learn through sensory impressions and motor activities.
- Examiners frequently mix theories from different psychologists (like Freud or Erikson) to test conceptual discrimination.
