Interest in object, reaching and grasping
With Orson’s increased physicality, we look at how he is beginning to explore the world around him as his hand eye coordination develops too. In this chapter Maria Robinson explains what physiological changes are taking place in the brain.Good for looking at
- Fine motor development
- Hand eye coordination
- Object play
- Brain development
- Babies
- Parents
- 00:13
- Austin's fine motor skills are also developing.
- 00:14
- And he's beginning to make movement
- 00:19
- that show a greater degree of hand-eye coordination.
- 00:23
- This is linked to an increasing interest in objects.
- 00:26
- His vision has also become more sophisticated.
- 00:29
- So together with muscular development,
- 00:33
- he's able to start acting on his new found interest.
- 00:38
- Previously, it was the human face that preoccupied him.
- 00:41
- Now he starts to work on finding out about objects.
- 00:44
- You've got too many
- 00:44
- Choosing what
- 00:45
- he's interested in is one thing.
- 00:46
- Trying to coordinate what he sees with controlling his hand,
- 00:49
- is an extremely difficult task.
- 00:53
- You just
- 00:59
- want them all.
- 00:59
- Oh, you dropped them.
- 01:00
- And again, it's a repetition,
- 01:02
- that his visual and motor development
- 01:04
- will become more accurate.
- 01:08
- Sounds in the brain
- 01:09
- start to make all these connections.
- 01:11
- And the more familiar anything becomes,
- 01:14
- the more efficient, that actually happens.
- 01:16
- And we can see this in the film, with Austin.
- 01:19
- As he's beginning to reach out,
- 01:20
- you can see, what hard work it is for him,
- 01:23
- as he starts to try and grab hold of a toy or something.
- 01:27
- And then, overtime we begin to see,
- 01:30
- that this becomes much more smooth,
- 01:32
- as he's able to reach out, and grab something.
- 01:34
- And, this is because,
- 01:36
- what's happening in the brain is,
- 01:37
- when you're starting to learn to do something,
- 01:40
- lots and lots and lots of connections are made,
- 01:42
- and then gradually, as you become more efficient,
- 01:45
- all the connections that are not needed,
- 01:48
- start to get pruned away,
- 01:49
- because they're not used, and they're not needed.
- 01:52
- So that phrase,
- 01:53
- "Use it or loose it."
- 01:54
- Is actually quite true because those connections,
- 01:57
- that we don't need,
- 01:58
- seem to actually wither away.
- 02:07
- You know what to do?
- 02:09
- As you can see,
- 02:11
- there's much to learn about objects,
- 02:13
- and Austin will spend increasing amounts of time
- 02:17
- They often go straight to his mouth.
- 02:20
- As this is
- 02:24
- the area with the most sensitive receptors.
- 02:32
- While he's trying to manipulate objects
- 02:35
- they often get dropped.
- 02:37
- Is it going on the floor?
- 02:38
- When they disappear,
- 02:40
- as far as Austin's concerned.
- 02:42
- They cease to exist.
- 02:45
- So he doesn't look for them.
- 02:47
- At this age, he can't understand
- 02:50
- that he just can't see them.
