Step 1: Concept
This question explores the psychological developmental stages of human life and their classic associated behavioral activities and characteristics.
Step 2: Meaning
Categorizing typical socioemotional and physical milestones (such as sensorimotor skills, peer focus, identity search) into chronological developmental stages as established in developmental psychology (e.g., Santrock's life-span developmental stages).
Step 3: Analysis
[leftmargin=20pt, itemsep=3pt, topsep=4pt]
• A. Infancy – II. Sensorimotor Coordination: Infancy (birth to 2 years) is characterized by exploring the world through senses and developing basic sensorimotor coordination (Piaget's sensorimotor stage).
• B. Early childhood – III. Spends many hours with peers: Early childhood (preschool years) is when children begin developing active social networks, spending significant time interacting and playing with peers.
• C. Middle and late childhood – I. Interacts more with wider social world: During middle and late childhood (elementary school years), children step beyond the family unit and interact heavily with the broader school and social environment.
• D. Adolescence – IV. Intensely pursues independence and seeks own identity: Adolescence is characterized by Erik Erikson's stage of "identity vs. role confusion," where teens intensely seek autonomy, independence, and self-identity.
Step 4: Conclusion
Matching these developmental behaviors correctly results in A-II, B-III, C-I, D-IV, which corresponds to option (B).
Final Answer: (B)
