Cognitive And Pragmatic Development Flashcards
Brain Development Order:
Lower Brain- Bodily Functions
Cerebellum & Basal Ganglia-Movement
Motor Cortex-Volitional Movement
Visual Cortex-Visual Processing
Limbic System-Emotions
Cerebral Cortex-Higher Thinking
myelination
myelin sheath is that fatty tissue tube which insulates the axon making sure that the impulse is sent quickly, efficiently and to a specified receiver.
Synaptogenesis
formation of synapses between neurons.
Neural Pruning
removal of neural pathways.
Sensation
Ability to register sensory information (light, touch, taste, sound, smell).
Overstimulation
If a touch or a sound is stronger or louder, the child responds in kind. This is because the cortex itself is immature, and firing on all cylinders, as they say.
Overstimulation
The state of agitation as a result of the inability to ignore stimuli.
Habituation
The only way in which infants begin to learn how to ignore stimuli is through habituation.
Habituation
Disregarding a stimulus because it is no longer “novel.”
If you’ve ever worked in fast food, you’ve likely experienced this. During the first few days of working, you will notice the beeping timers for fryers and other tools going off constantly. However, after a few days, or even a few hours for some, the timers begin to fade into the general music of the scene. Luckily, however, the alarms do not fade completely, or you’d miss a timer and burn an entire batch of fries.
Selective Attention
Once a child begins to be able to habituate to sounds which become less novel – or new to her - she now has the cognitive reserves to attend to just one thing.
selective attention:
The ability to focus on one stimulus and filter sensations to maintain a stable state.
It tends to be the things that are important to her, like in the “Cocktail Effect” where you hear your own name it a crowd, even though it was not said more loudly than anything else, you still attend to it because it is personally important.
Perception
Ability to integrate sensory information and prior experiences.
Discrimination
Ability to identify the salient characteristics of a stimulus.
Reflex Development
Children are born with reflexes, which in healthy children are developed in utero. For instance, thumb-sucking, blinking, as well as heart rate changes due to external stimuli all develop before birth.
Reflexes
involuntary neuro-motor responses to stimulation.
Primitive reflexes are those that are present at birth but disappear by 6 months as part of normal development. Typically their role is to support survival in the early weeks, until the child develops control over her muscles.
True
In general, oral motor development is the first area of motor skill which infants really master. It begins with an up-down movement (as in aphasic bite) which gradually develops into front-to-back control, graded, rotational and lateral movement. The last of this sequence is made possible by the emerging ability of the child to separate jaw movement from the movement of the lips, tongue, and cheeks.
True
Motor Speech
Planning, preparation, and execution of muscle movement for oral communication.
The sounds that they begin to make when they are not crying are called quasi-resonant nuclei, or QRN. These are back-of-the-throat sounds which are half consonant and half vowel. As they begin to gain some control, their sounds take on true vowels and consonants, and they begin to take turns with their vocalizations in “protoconversations.”
True
Stimuli
In the beginning, a stimulus, or several stimuli occur.
Attention
Attention is the first active role a child has in learning. The stimuli that are attended to will have a chance to be “processed.” But, the stimuli not attended to will be ignored.
Perception
The next step is to compare stimuli to other experiences. If it is a stimulus that has been attended to before, it has a higher likelihood of being processed this time. Remember - human brains love patterns.
Discrimination
Relevant characteristics of the stimuli are identified. Think about a road sign. If you used the base of the sign (the wooden or metal sticks) to discriminate between them, you might get into an accident, because you were using the wrong characteristics. The salient characteristics are the words or images on the top shape. Discrimination means looking for what’s important in a stimulus. Combined, Perception and Discrimination constitute what is called “working” or “short term” memory.
Organization
Researchers have shown that we can maintain about 7-12 units of information in our mind at once. This is what we call our “working memory.” Have you ever tried to remember a shopping list that was longer than ten items, or remembered the names of more than ten new people at a party? There is a real, scientific reason why this is difficult, and it’s why the organization of information is so important. When you organize information, which we can also call “chunking,” we can turn 144 pieces of information into 12 chunked units of information. It’s a great thing to remember when you are studying for a test. Organization is the first half of creating a long term memory.
Memory (Recall)
Recall is the ability of your brain to send back out what it has taken in. Researchers say that while you learn 10% of what is taught by listening, 50% of what is taught by actively engaging in the material, and 90% of what is taught when you have to turn around and teach it yourself. That is one reason why presentations are part of all my courses, and why recalling information is so important for solidifying learning. When you hear a new name at a party, be sure to say the name, and recall it five minutes later—you will have processed it much better, and perhaps made a new friend or professional contact because of it.
Milestones in the Cognitive Development of Play:
Imitation, Causality (6 Months and Up), Object Permanence (8 Months) and Means-End (8 - 9 Months
Imitation
Doing what someone else does. It starts with mirror neurons prompting smile responses when an adult smiles. It’s also nurtured in the protoconversation activities at two months, and as children refine their motor ability they become better imitators of the world around them.
Causality (6 Months and Up
A child begins to notice that an action she made had an effect on something nearby - weather it was her waving arm knocking a bottle to the floor, or a reactionary scream bringing an adult near. It wasn’t on purpose, but she noticed the result.
Object Permanence (8 Months
Knowing something unseen still exists.
Milestones in the Cognitive Development of Play - Strategies:
Play, symbols, and know this progression
Play
If you didn’t have memory, you wouldn’t realize that you have attempted the same solution for the same problem, over and over. However, if you have some increased memory, paired with the drive to have an effect on the world, you now can try different strategies. This, in essence, is play.
Many of the two-year-olds I see in the intervention are missing this ability to create strategies. It often baffles parents when their child looks happy but does not talk. However, one of the painful conversations I sometimes have to have is that their child is never upset because they don’t remember their previous attempt and failure, or they don’t’ know what they are missing. It is really important that a child demonstrates some mild frustration at times because it demonstrates that they understand that they tried something and it didn’t work
Symbols
Once a child has Means-End behavior, based on the idea that they can have an effect on their world, and they know there is something they want that they don’t have, plus the ability to try multiple strategies, we finally see children trying to say words. Intention drives means-end behavior, object permanence provides a foundation for understanding that things can be represented even when they don’t exist. And finally, trying multiple strategies, multiple motor patterns, make it possible for a child to finally hit on the right combination at the right time and yell out “bottle!”
Know this progression
it’s key to unlocking the puzzles of young children in early intervention.
