Physical Development Flashcards
Define the term cephalocaudal principle
Refers to the concept that development occurs from the head downward
Define the term “proximodistal”
Refers to the concept that development proceeds from the center of the body outward, i.e. the spinal cord develops before the outer parts of the body
What is REM sleep?
Active/light sleep
How do circadian rhythyms of newborns differ from adults
The circadian pattern in newborns is often “out of sync with that of adults, so they have different sleep patterns that correspond with different times of the 24 hour period
What is SIDS?
Sudden infant death syndrome
What are some risk factors of SIDS?
position of sleeping
Soft bedding
Maternal smoking
excessive heat
Define Dynamic systems theory
Development is determined by interaction between internal processes and contextual influences
congenitally organized behaviours
early behaviors of newborns that do not require specific external stimulation and that show more adaptability than simple reflexes
Define gross motor development
whole body general movements
Fine motor development
fine movements with hands
How does the mylenation of the neurons change with age?
They grow thicker
What is the last area to mature in the brain
Frontal lobe
describe plasticity
capacity of the brain to be affected by experience
What is a major change in brain development in teenagers?
Second wave of overproduction and pruning of synapes
Where are executive functions made?
Dorsal lateral prefrontal cortex
Define catch up growth
Quick growth after a disease that has inhibited growth
How much of sleep is REM sleep in babies, compared to adults?
50%; 20%
What is SIDS
Sudden unexpected and unexplained death of an infant less than 1 year (sudden infant death syndrome)
What are congenitally organized behaviours?
Early behaviours of babies that do not require external stimulation and show more adaptability than reflexes
What is an example of a congenitally organized behaviour?
Sucking
What do congenitally organized behaviours accomplish in the babuy
Means of:
- getting nourishment
- control and explore their environment
Define postural development
The increasing ability of the baby to control parts of its body, esp. the head and trunk
Define prehension
The ability to grasp and manipulate
