Flashcards in chapter 9 voluntary movements of infancy Deck (17):
1

what happens with the infant reflexes

dissapear

2

action of the brain

brain´s cortex inhibits reflexes from the lower brain area

3

voluntary movements

rudimentary movements (basic motor skills)

4

categories of voluntary movements

stability
locomotion
manipulation

5

stability

from head control to maintaining posture

6

exp. for stability

head control
body control
upright posture
standing

7

exp body control

rolling

8

exp. upright postue

sitting
standing

9

when does a child develop object manipulation

after 7/8 months
with learning how to sit without support

10

locomotion movement

prone(liegend) locomotion
crawling, creeping
one of the greatest accomplishments of infancy

11

walking

upright locomotion
7-12 months
influential in other developmental processes (speaking development)

12

stair climing

upright locomotion
13 months most able to ascend and half able to descend
90% learn descent after ascent

13

manipulation

important for exploration, discovery and achieving goals
reaching and grasping

14

manipulation phase I

reaching and grasping occurs at the same time
visually initiated
not visually controlled
child not capable to correct the error during reaching

15

manipulation phase II

wrist, hand finger/thumb control
pincer (schwere) like movement
visually guided reaching

16

bimanual control

one handed reaching becomes dominant
holding more than one toy at the time

17

relationship of reaching and postural control

better postural control -> improved reaching and general exploration
