Save
Development as a dynamic, lifelong Development reflects gradual, ongoing changes
process and expanding capabilities that build on earlier
skills across the entire lifespan, not just in
childhood.
Developmental milestones Observable achievements in skills or behaviors
(e.g., walking, first words) that typically occur in a
predictable sequence and support later, more
complex abilities.
Biophysical domain of development Aspect of development involving organ systems,
brain growth, sensory abilities, and motor skills.
Cognitive domain of development Aspect of development involving information
processing, language, learning, memory, and
problem solving.
Psychosocial domain of Aspect of development involving temperament,
development emotional regulation, attachment, personality, and
relationships.
Cephalocaudal development Developmental pattern in which growth and
control progress from head to toe (head control →
trunk control → standing/walking).
, Proximodistal development Developmental pattern in which growth and
control progress from the center of the body
outward (trunk → arms → hands → fingers).
Systematic and successive The idea that developmental changes occur in an
development organized, predictable sequence, with each new
skill building on earlier ones.
Individual variation in developmental The concept that children achieve milestones at
pace different rates within a typical range (e.g., early
walking but later talking, or vice versa).
Critical period A specific time window when an experience or
exposure must occur for normal development; if
missed, the skill may be extremely difficult or
impossible to acquire later.
Sensitive period A time frame when development of a skill is easiest
and most efficient, but still possible outside this
window (a "window of opportunity").
Nature (in development) Biological influences on development, including
genetics, brain structure, and inherited traits.
Nurture (in development) Environmental influences on development,
including family, culture, school, peers, and
broader social context.
Nature-nurture interaction The understanding that genetics and environment
work together to shape development, rather than
acting independently.
