child development Flashcards
define development
process by which each child evolves into an independent adult
what are the antenatal environmental causes of damage to brain development?
- infectious agents: toxoplasmosis, rubella, cytomegalovirus, herpes
- hormones: androgenic agents, DES, maternal diabetes, maternal obesity
- drugs: mainly valproic acid, alcohol
what are the postnatal environmental causes of damage to brain developmental?
- infections
- metabolic disorders
- toxins
- trauma
- domestic violence
- malnutrition
- maternal mental health
what causes spina bifida cystica?
due to failure of ant or post neuropore
what are the consequences of this?
- neuroggenic bowel and bladder incontinence
- lower limb paralysis
- fractures and joint contractures
- developmental deformities and learning difficulties
- hydrocephalus and meningitis
what are the 4 developmental domains?
- gross motor performance
- vision and fine motor
- hearing, speech, language
- social, emotional, behavioural
define median age and limit age
median age: when half of the standard population of children achieve that level
limit age: age by which they should have achieved the level and is equal to 2SD from mean age
what are the developmental milestones in gross motor performance?
- New born: limbs flexed in symmetrical posture, head lag on pulling up
- 6-8 weeks: raises head to 45 degrees in prone
- 6-8 months: sits without support
- 8-9 months: crawling
- 10 months: cruising around furniture
- 12 months: walks unsteadily
- 15 months: walks steadily
what are primitive reflexes?
- Protective and serve to promote support, balance and orientation
- Should disappear by 4-6 months
what are the 5 primitive reflexes?
- Stepping (baby appears to take steps when held upright)
- Moro (response to sudden loss of support, when infant feels as if it is falling, involves arm abduction, adduction, crying)
- Grasp
- Asymmetric tonic reflex (which way babies head is turned, arm outstretches)
- Rooting (stroke baby’s cheek, causes baby to turn and open mouth)
what are the protective reflexes and when do they develop?
- Develop from 5 months
1. Downward parachute reflex
2. Sideward protective reflex
3. Forward protective reflex
4. Backward protective reflex
describe the downward parachute reflex
- 5 months
- when held and rapidly lowered, infant extends and abducts both legs and feet are plantigrade
describe the sideward protective reflex
6 months
- infant puts arms out to save if tilted off balance
describe the forward protective reflex
- 7 months
- arms and hands extend on forward descent to ground
describe the backward protective reflex
- 9 months
- backward protective extension of both arms when pushed backwards in sitting position
what are the milestones in fine motor and vision domain?
- 6 weeks: turns head to follow object
- 4 months: reaches out to toys
- 4-6 months: palmar grasp
- 7 months: transfers between hands
- 10 months: mature pincer grip
- 16-18 months: marks with crayons
- 14 months-4years: towering
- 2-5 years: ability to draw without seeing how its done
what is object permanence? when is it attained?
9 months
idea that when out of sight, not out of mind
what are the developmental milestones in language and hearing?
- new born: startles
- 3-4 months: vocalizes alone or when spoken to
- 7 months: turns to soft sounds out of sight
- 7-10 months: uses sound indiscriminately or discriminately
- 12 months: 2 to 3 words other than dada or mama
- 18 months: 6-10 words
- 20-24 months: makes simple phrases
- 1.5-3 years: talk constantly on 3-4 word sentences
