toes curl outward like a fan when sole of foot stroked

25

A

Around 6 months

26
Q

What happens after 6 months with reflexes?

A

Voluntary control starts to take over

27
Q

What basic movements are occurring when voluntary movements take over?

A

  • manipulative movements
  • locomotion movements
28
Q

What is gross motor development?

A

Large muscle movement of arms, legs, torso

29
Q

What is the goal for younger children with their gross motor skills?

A

Mastery

30
Q

What is the goal for older adults with their gross motor skills?

A

Mastery as means to na end. More complex skills

31
Q

What is fine motor skills?

A

Small muscles throughout the body (fingers, toes etc)

32
Q

What is an example of fine motor development for newborn?

A

They attempt to grasp, but not enough control. By 4-5 moths they emerge as two separate skills.

33

fingers close against palm

34

thumb and forefinger

A

pincer grasp objects, undo buttons, jigsaw puzzles

36
Q

What fine motor skills develop at 4 years?

A

fold paper, build smooth towers

37
Q

What motor developments have happened at 2 years?

A

walk smoothly and rhythmically

38
Q

What motor developments have happened at 3 years?

A

run, skip, jump

39
Q

What happens in motor development after 5 years?

A

walk backwards, change direction while running

40
Q

What occurs between 7-17 years in regard to motor skills?

A

significant improvement in, especially gross, motor skills

41
Q

What happens when your’e 30 years old with motor skills?

A

You are at peak physical performance.

42
Q

What happens between 30-70 years with motor skills?

A

25-30% decline in muscle mass, strength

43
Q

What happens when your’e 80 in regard to motor skills

A

Lose 50% of muscle mass

44
Q

What are 3 mechanisms for which motor skills improve?

A
  1. physical development
  2. neural development
  3. practice
45
Q

What neuronal effects are occurring in neural development?

A

greater myelination of cerebellar neurons, lead to better balance and improved co ordination

46
Q
  1. Are there sex differences in motor development?
  2. What are these differences?
  3. What has recent research revealed?
A
  1. Yes but only minor
  2. Boys tend to have greater muscle, more rough play. Girls greater balance, more quiet activities.
  3. This has recently been linked to social role differences more than biological factors.
47
Q

What happens in children deprived of motor practise in the first 12-24 months?

A

They were delayed in sitting and walking

48
Q

What does the dynamic approach say about motor skill development?

A

That motor. behaviours are not inevitable physical milestones

49
Q

What do practising physical activities help develop? (3)

A
  1. gross motor skills
  2. fine motor skills
  3. social skills
50
Q

Children who perceive themselves as having poor motor skills often experience what?

A

That they are rejected by peers.

51
Q

A

1 hour of exercise per day

52
Q

What is the comparison with how much exercise the government recommends vs. what the school does?

The school only requires at least 2 hours of physical activity per week. Much less than the government recommends.
