Human Development Stages

Study Notes

Prenatal Development: The period from conception to birth, during which the fetus develops and grows inside the womb.
- Divided into three stages: germinal, embryonic, and fetal development.
Infancy and Toddlerhood: The stage from birth to approximately 3 years old, characterized by rapid physical growth and development.
- Milestones include crawling, walking, and language development.
Early Childhood: The stage from approximately 3 to 6 years old, marked by continued physical growth and the development of social and emotional skills.
- Milestones include improved language skills, development of imagination, and increased independence.
Middle Childhood: The stage from approximately 6 to 12 years old, characterized by refinement of social and emotional skills, and increased cognitive abilities.
- Milestones include development of friendships, improved problem-solving skills, and increased academic achievement.
Adolescence: The stage from approximately 12 to 18 years old, marked by significant physical, social, and emotional changes.
- Milestones include puberty, development of identity, and increased independence.
Adulthood: The stage from approximately 18 years old and beyond, characterized by continued physical, social, and emotional development.
- Milestones include establishment of career, development of romantic relationships, and increased responsibility.

Nature vs. Nurture: The debate about whether development is influenced more by genetics (nature) or environment (nurture).
Biological Theory: Focuses on the role of genetics and biological processes in development.
Psychological Theory: Emphasizes the role of environment, learning, and experience in development.
Ecological Systems Theory: Views development as influenced by multiple levels of the environment, from immediate to societal.

Genetics: The role of inherited traits in shaping development.
Environment: The impact of external factors, such as family, culture, and society, on development.
Socioeconomic Status: The influence of socioeconomic factors, such as access to resources and opportunities, on development.
Cultural Factors: The role of cultural values, beliefs, and practices in shaping development.
Nutrition and Health: The impact of adequate nutrition and health on development.
