The basis of our first language and our largest sensory organ.
What is the tactile system?
100
The structure of the brain responsible for one's balance, posture and coordination.
What is the cerebellum?
100
An adaptive response to a sensory experience.
What is a purposeful, goal-oriented, efficient response to sensory input for use?
100
A child who cannot bear to be touched, even by her/his own clothing and shoes.
What is one symptom, which may be exhibited by a child with tactile hypersensitivity or tactile defensiveness?
200
It is responsible for how one perceives balance, equilibrium, bilateral coordination, speed and direction of one's own body movements through the environment.
What is the vestibular system?
200
The brainstem, the cerebellum and the thalamus.
What are the three brain structures that operate at the unconscious level?
200
It is demonstrated when the tactile system allows us to discern a penny from a dime without looking at the coins.
What is discrimination?
200
A student who cannot hold a cup of water without spilling it, because he/she is either holding the cup too tightly or too loosely.
What is an example of difficulty grading movements, not sensing the appropriate amount of pressure required to complete an everyday task?
300
The proprioceptive system.
What provides cognitive information to the brain about exactly where our body parts are in space, our sense of position and balance?
300
Part of the limbic system, it is linked to cognitive ability and memory retention by helping to form, organize and store memories.
What is the hippocampus?
300
Eye-movement control, which allows us to read, effortlessly moving from one word to the next, to fixate on one word or letter, and to track a moving object.
What are visual efficiency skills: saccadic, fixation and pursuits?
300
As a baby, one who did not like "tummy time" and later as a kindergartener, fears movement, has decreased muscle tone and appears lazy and unmotivated on the playground.
What may a child's actions look like with postural disorder?
400
A student who craves/needs lots of movement . . . rocking, swinging, spinning and/or jumping.
How may a student present with a hyposensitive vestibular system?
400
The sympathetic and the parasympathetic nervous systems.
What are the two key parts of the autonomic nervous system, where one part controls our fight/flight reactions and alerts us to danger and the other part returns us to calm and helps us regain control?
400
Balancing the inhibitory and facilitatory messages in our brains, which allows us to shift from one activity to another.
What is sensory modulation?
400
The proprioceptive, tactile and vestibular senses.
What are the three primary senses emphasized by Dr. Jean Ayres' research and findings, since they dominate a child's early interactions with the world?
