PSYC 140 (Portage) Module 3
1. Key infant reflexes < Ans >
1) Rooting
2) Moro Reflex
3) Grasping/Palmer Reflex
4) Stepping Reflex
2. Rooting < > A reflex where a baby turns their head when the cheek or mouth is
touched.
3. Moro reflex < > A startled response: infant arches back and throws out limbs.
4. Palmer reflex < > A spontaneous grasp made by an infant when the palm is rubbed.
5. Stepping reflex < > Infant makes stepping motions when held above surfaces.
6. Sleep states < Ans > nREM and REM sleep
7. nREM sleep < > Regular sleep, non-rapid eye movement, where the baby is nearly
motionless.
8. REM sleep < > Irregular sleep, characterized by uneven breathing, half of an infant's
daily sleep pattern.
9. Shaken baby syndrome < > Brain damage caused by an infant being violently
shaken.
10. 5Ss of soothing < >
1) Swaddling
2) Side/stomach
3) Swinging
4) Shushing sounds
5) Sucking
11. Why 5Ss work < Ans > -Touch releases endorphins
1/6
, -Soothing noises are calming
-Swinging is similar to womb
-Swaddling limits overstimulation
12. Infancy < > -First two years of life
-Reaching 30 lbs
-32-35in tall
13. Two types of growth < Ans >
Cephalocaudal Proximodistal
14. Cephalocaudal < > Growth starts at the top with the head.
-Brain and skull are primary locations of growth (limbs/body later).
15. Overproduction < > Brains have more synaptic connections than needed.
16. Neural pruning < > Important connections are maintained, and unimportant ones are
discarded.
17. Critical periods < > Must learn information within a specific span of time, otherwise
brains won't develop
18. Example of critical periods < > Language acquisition (before 5yo), deaf children
babbling in sign
