Reflexes- these movements are
automatic, involuntary reactions to
various forms of external stimulation
and some of these occur within the
uterus and also the first visible
movements of a newborn
Locomotor
Primitive
Postural
Development of voluntary movement
Reflexes gradually lose their
dominance as voluntary control
emerges. Most of these primitive
reflexes are overidden by six
months. The initial emergence of
voluntary movement and lasting
until two years of age is referred to
as 'the rudimentary movement
phase' or motor development
Appears in a
highly predictable
sequence
Includes movements such as gaining control
of the head, neck and trunk muscles;
manipulative postural movements
(reaching/grasping) and basic locomotor
movements (crawling/walking)
6 months - 2 years
Refinement of Voluntary Movement
As children gain increased control of these
movements, they can also control their interactions
with the environment. From two years till six years
the increased control emerges with the refinement
of movement sequences with those such as walking,
jumping and catching.
Two year olds have relatively poor spatial and
temporal integration of movement resulting in a
lack or coordination
By three to four years, they have
greater control and begin to show
signs of automaticity
Coordination develops fully in later childhood
and into adolescence. Complex movement skills
are mastered due to sensory/neurological
maturation, environmental interaction and
practice, and the development of high mental
processes.
