10 Key Concepts in Developmental Psychology
Nature vs. Nurture
- The debate centers on the influence of genetics (nature) versus environment (nurture) in human development.
- Most psychologists agree that both factors interact to shape behavior, highlighting the complexity of development.
Critical Period
- Certain stages of development must occur within specific time frames for proper growth.
- An example is language acquisition, which has a critical period during early childhood.
Attachment Theory
- Emphasizes the importance of a strong emotional bond between an infant and caregiver.
- Secure attachment fosters healthier social and emotional development throughout life.
Cognitive Development
- Describes stages of cognitive growth in children: sensory motor, pre-operational, concrete operational, and formal operational.
- Highlights how children's thinking evolves from reflexive actions to abstract reasoning.
Social Learning Theory
- Focuses on learning through observation and imitation.
- Children acquire behaviors by watching others, particularly through modeling and reinforcement processes.
Zone of Proximal Development (ZPD)
- Refers to the gap between what a child can do independently versus with guidance.
- Emphasizes the role of social interaction in facilitating learning experiences.
Moral Development
- Stages describe progression from basic understanding of right/wrong to complex ethical reasoning.
- Children evolve from focusing on personal consequences to higher-order principles like justice.
Temperament
- Refers to biologically based tendencies affecting how children respond to their environment.
- Influences emotional reactions, attention, and behavior across different developmental stages.
Resilience
- Involves coping with stress and adversity effectively.
- Resilient children are better equipped to overcome challenges due to supportive relationships and adaptability.
Developmental Milestones
- Behaviors or skills typically seen as children grow (e.g., walking, talking).
- Tracking milestones helps assess if development is on track or if intervention is needed.
