Development is lifelong, multidimensional (biological/cognitive/socioemotional), multidirectional, plastic (changeable), and contextual.
o Normative Age-Graded: Similar for people in a particular age group (e.g., puberty, starting school).
o Normative History-Graded: Common to people of a particular generation (e.g., living through a pandemic).
o Non-normative Life Events: Unusual occurrences that have a major impact (e.g., losing a parent young).

o Normative Age-Graded
Common to people of a particular generation (e.g., living through a pandemic).
o Normative History-Graded
Unusual occurrences that have a major impact (e.g., losing a parent young).
o Non-normative Life Events
Where you live (family, peers, school).
o Microsystem
Relations between microsystems (e.g., your parents meeting your teacher).
o Mesosystem
Links between a social setting where you don’t have an active role and your immediate context (e.g., a parent’s stressful job affecting the child at home).
o Exosystem
The culture you live in.
o Macrosystem
The timing of events over your life
o Chronosystem
biological inheritance
nature
environmental experiences
nurture
Creation of the zygote, cell division, and attachment to the uterine wall.
o Blastocyst: Inner layer (becomes embryo).
o Trophoblast: Outer layer (becomes nutrition/support)
Inner layer (becomes embryo).
o Blastocyst
Outer layer (becomes nutrition/support).
o Trophoblast
Rate of cell differentiation intensifies.
o Endoderm: Inner layer (digestive/respiratory systems).
o Mesoderm: Middle layer (circulatory system, bones, muscles).
o Ectoderm: Outer layer (nervous system, sensory receptors).
o 🚨 EXAM ALERT: Organogenesis occurs here—this is when the baby is most vulnerable to major structural defects.
