INFANCY: BASIC PROCESSES
EMBRYONIC
DEVELOPMENT
TO FULL TERM
•At around 20 weeks
we see the emergence
of the IPS; the area at
the back of the brain.
•It is involved in
numbers and
quantities.
•Birth is not the
beginning of cognition.
MILESTONES IN
MOTOR
DEVELOPMENT
•1. Lifts head up (2
months)
•2. Rolls over (2.5
months)
•3. Sits propped up (3
months)
•4. Sits without support
(6 months)
•5. Stands holding on (6.5 months)
•6. Walks holding on (9 months).
•Stands momentarily (10 months)
•Stands alone (11 months)
•Walks alone (12 months)
•Walks backwards (14 months)
•Walks up steps (17 months)
•Kicks ball forward (20 months)
INFANT REFLEXES
•We are interested in newborn reflexes as they display innate, automatic responses to different
forms of stimulation and gives a quick indication of neurological status. Some are refined over
time too become complex patterns of behaviour, others drop out.
•Common reflexes include;
•Babinski: fanning out of toes when foot stroked.
•Crawling: rhythmic moving of arms and legs when on tummy and pressure applied to soles of
feet.
•Grasping: finger grasp when object placed in hand.
•Rooting: head turn with mouth open when touched on cheek.
•Moro: outstretched arms & arched back when startled or loss of support.
•Stepping: toes and foot coordinated movements when supported on a hard surface, moved
forward.
Document Summary
To full term: at around 20 weeks we see the emergence of the ips; the area at the back of the brain, it is involved in numbers and quantities, birth is not the beginning of cognition. Walks holding on (9 months): stands momentarily (10 months, stands alone (11 months, walks alone (12 months, walks backwards (14 months, walks up steps (17 months, kicks ball forward (20 months) Infant reflexes: we are interested in newborn reflexes as they display innate, automatic responses to different forms of stimulation and gives a quick indication of neurological status. Infant sensory abilities: are these a basis of cognition, sight touch sound taste smell. Touch: what can infants feel: newborns are sensitive to temperature change, their sensitivity to pain is controversial (eg. circumcision). Physiological indicators (crying, stress hormones, hard to comfort, etc) suggest pain, but it is not possible to assess cognitive components of pain (mirror neurons).
