Human Development Stages

Prenatal Development: The period from conception to birth, during which a fetus grows and develops inside the womb.
- Divided into three trimesters, each lasting approximately 13 weeks.
- Major milestones include organ formation, sensory development, and motor skill development.
Infancy and Toddlerhood: The period from birth to age 3, characterized by rapid physical and cognitive growth.
- Infants develop motor skills, language, and social skills.
- Toddlers learn to navigate their environment, test boundaries, and develop independence.
Early Childhood: The period from age 4 to 6, marked by continued cognitive, social, and emotional development.
- Children develop language, problem-solving, and social skills.
- They begin to form friendships and learn to cooperate with others.
Middle Childhood: The period from age 7 to 12, characterized by refinement of skills and increased independence.
- Children develop more complex cognitive skills, such as problem-solving and critical thinking.
- They begin to form identity and develop relationships outside of the family.
Adolescence: The period from age 13 to 19, marked by significant physical, emotional, and social changes.
- Adolescents experience puberty, develop emotional regulation, and form romantic relationships.
- They explore identity, develop independence, and prepare for adulthood.

Nature vs. Nurture: A debate about whether development is influenced more by genetic factors (nature) or environmental factors (nurture).
Piaget's Theory: Jean Piaget's theory that children progress through four stages of cognitive development, each characterized by a unique way of thinking and understanding the world.
Vygotsky's Theory: Lev Vygotsky's theory that social interaction and language play a crucial role in cognitive development.
Erikson's Psychosocial Theory: Erik Erikson's theory that development is influenced by eight stages of psychosocial development, each characterized by a unique conflict or crisis.

Genetics: Genetic factors that influence development, such as inherited traits and predispositions.
Environment: Environmental factors that influence development, such as family, culture, and socioeconomic status.
Nutrition and Health: The impact of nutrition and health on development, including the role of nutrition in physical and cognitive growth.
Socioeconomic Status: The impact of socioeconomic status on development, including access to resources, education, and opportunities.
