Normal child development Flashcards
What are the four fields of development (in the order they occur)
Grossmotor
Vision and fine motor
Hearing, Speech, Language
Social, Emotional, Behavioural
What is the median age
age where half the standard population of children achieve a certain level
What is the limit age
age by which the developmental milestone should have been achieved
2 st devs above mean
When is motor development most rapid?
in first year of life
when maturation of CNS and myelination is occurring q
How do you adjust for prematurity in development
baby born preterm: calculates age from expected delivery date (NOT actual date)
until 2 years old
What is specific developmental delay
only one domain is delayed
What is global developmental delay
two or more domains delayed
What are primitive reflexes?
present at birth, disappear with time
What is the list of primitive reflexes
Moro Grasp Rooting Stepping response ASYMMETRICAL TONIC NECK REFLEX
What is ASYMMETRICAL TONIC NECK REFLEX
lying supine, the infant adopts an outstretched arm top the side to which the head is turned
what is moro
sudden extension of the head causes symmetrical extension, then flexion of the arms
what is grasp
flexion of fingers when someone thing is placed in the palm
what is rooting
head turns to stimulus when touched near mouth
what is the stepping response
stepping movements when held vertically and dorsum of feet touch a surface
what are postural reflexes
replace primitive reflexes
What are the 4 postural reflexes
Labyrintthine righting
Postural support
Lateral proppring
Parachute
What is Labyrintthine righting
head moves in opposite direction to which it is tilted
What is postural support
when held upright, legs take weight and bounce
what is lateral propping
in sitting, arm extends on the side to which the child falls as a saving mechanism
what is parachute
when suspended face down, arms extend as if to save themselves
what is the newborn hearing test that is done in everyone
Otoacoustic emission
What occurs in OAE
earphone produces a sound which evokes echo/emission from ear if cochlear function is normal
What other hearing test can be done
Auditory brainstem response audiometry
EEG waveform
