Q

how do primitives contribute to birthing process?

Q

primitive reflexes are considered ? if they remain active beyond the first year of life
–> this is a sign of?

Q

what should happen to primitive and postural reflexes between ages 6-12 months?

A

they should be inhibited by the brain allowing more sophisticated neural structures to develop

Q

motor control lays the foundation for? and we acquire new skills by ?

- moving our bodies intentionally

Q

why do we need to have intentional control of our muscles?

A

When those muscles obey an unconscious reflex instead of responding to our intention, then the activity is confusing and cannot become an automatic learned skill.

Q

academic learning depends on?

- if this doesn’t happen?

A

auto-mization of basic skills at their physical level

, unsatisfactory peer relationships despite good intelligence

Q

there is a discussion on whether there is a link between reflexes and ?

Q

explain continuous development

A

motor changes occur in a linear fashion during an individual’s life and that each change is dependent on the development of the prior period.

Q

explain discontinuous development

A

each stage of motor development has a new and unique feature that is added to distinguish it from the previous stage.

during discontinuity development, behavior and skills change how? it is known as ? development

A
  • qualitatively

Q

4 types of reflexes and what they are

A
  1. primitive: survival and protection
  2. postural: reaction to gravity
  3. locomotor: resemble voluntary locomotion (ex, pressure on babies foot)

  3. survival
31
Q

name 5 primitive reflexes? when are they supressed?

A

sucking, rooting, moro, grasping, tonic neck

–> 3-4 months after birth

32
Q

Protective response—if infant starts to fall, arms and legs extend outward, hands open, fingers spread

A

moro reflex

33
Q

As the higher brain centres begin to function, postural reactions enter the infant’s repertoire
–> this gives the infant the ability to ?

A

react to gravitational forces and changes in equilibrium

34
Q

Related to upright posture , Head tilts in the opposite direction of body tilt , Babies corrects

A

labyrinthine reflex

35
Q

when does the labyrinthine reflex emerge? and it endure through?

A
  • 2 months

- through 1st year of life

36
Q

5 locomotor reflexes

–> what do they resemble?

A
  1. grasping
  2. crawling
  3. stepping
  4. swimming
    - -> later voluntary locomotor movements
37
Q

when are locomotor reflexes integrated?

A

5-6 months

38
Q

touch side of mouth they turn and suck what ever touched their mouth

A

rooting reflex

39
Q

Pressure on sole of foot from touching a flat surface elicits crude stepping
–> when does this reflex occur? and disappear?

A

  • 4 months
40
Q

toes flaring out

A

babinsky reflex

41
Q

what can babies with downsyndrome do to help elicit these reflexes faster to make them walk sooner

A

-walk on baby treadmill with help

42
Q

what are stereotypies

A
  • Stereotypic rhythmic (repetitive) motions that appear in the absence of any known stimuli
  • -> Not voluntary or goal-oriented However, appearance predictable and orderly

do fatter babies show delays?

A

yes

avoid overfeeding babies, they will eat when they are hungry

mastering little motor skills will allow babies too?

57
Q

studies found that novice walkers ? more than expert crawlers but novice walkers ? more than expert crawlers

A
  • fell more

- moved more

58
Q

on average how many times do toddlers fall per hour

A

17 times (babies are stupid) lol

59
Q

sequence of stands

A
  1. holding on (6-8 months)

Q

crawling (dragging body) occurs when?

creeping (on hands and knees) occurs when?

A

6-8 months

-8-10 months

61
Q

crawling and creeping is important for?

A

building up muscles needed for walking and balance

62
Q

perfected walking happens at

A

5 years

63
Q

what is the initial immature walking pattern

A

High guard-arm position, wide base of support, flat- footed contact, and toeing- out

64
Q

with improved balance, what happens to walking posture?

A

the base of support narrows, the arms are lowered and work in opposition to the legs, and the toes point more in a forward direction
- there is a heel strike

65
Q

are baby walkers good?

A

NO! serious injuries

66
Q

the greatest risk of head injuries in children under age 2

A

baby walkers
