The process by which an organism (human or animal) grows and changes through its' life-span
Continuous pattern of developmental stage
The change that occurs at steady pace - may show a constant, consistent improvement orgrowth.
Discontinuous pattern of developmental change
Development occurs in stages - every age/stage is qualitatively different
Asynchronous pattern of developmental change
Skills may develop faster than others - onset of development may occur quicker.
Normative age-graded (major influence on life-span development)
Chronological association (e.g., puberty or starting school)
Normative history graded (major influence on life-span development)
Historical time association (famine, natural disaster, war or civil unrest, technological change).
Non-normative life events (major influence on life-span development)
Major event that can occur at any point in life-span (e.g., major accident, divorce, bereavement, job loss) - Neither chronological or historical association.
Microsystem (systems of ecological model)
Relations between the developing person and immediate environment (e.g., school, day-care centre, peers)
Mesosystem (system of ecological model)
A system of microsystems - they are linked amongst them and the individual participates directly
Exosystem (system of ecological model)
Settings in which the individual does not participate directly - however, it does have an effect on individual's development (e.g., extended family, mass media, workplace)
Macrosystem (system of ecological model)
The interactions between microsystems - e.g., when two microsystems interact.
Chronosystem (system of ecological model)
Changes in person or environment over time or their transitions - (e.g., starting school)
