Test your sensory integration knowledge with this fun quiz.  Answer the following
questions about sensory integration.  The answer key is below.

1.  Deficits in motor planning have been linked to a decreased ability to discriminate:

A.  Tactile input
B.  Vestibular input
C.  Proprioceptive input
D.  All of the above

2.  Jean Ayres determined that clients who experience tactile defensiveness benefit the most from two of the
following (choose two):

A.  More tactile input
B.  Deep pressure
C.  Proprioceptive input
D.  Vestibular input

3.  What is the considered to be the most organizing type of sensory input?

A.  Tactile input
B.  Proprioceptive input
C.  Visual input
D.  Vestibular input        

4.  True or False:
Gravitational insecurity and aversive responses to movement are the same sensory modulation disorder.                

5.  True or False:
A child's responses to sensory input always occur right after the initial input.        

6.  The four types of sensory modulation dysfunction are:
1.______________________________                                                                   
2.______________________________                                                                   
3.______________________________                                                                  
4.______________________________                                                                  


7.  The most common type of sensory modulation dysfunction is:
______________________________________ .                                                                                                                     
                                          .


8.  Somatodsypraxia is considered to be a result of poor processing of:

A.  Tactile, vestibular and proprioceptive input
B.  Vestibular, auditory and visual input
C.  Tactile, proprioceptive and auditory input
D.  Only vestibular input


9.  A disorder of praxis that exhibits motor planning deficits and is developmentally based is
:__________________________________.                                                                        .        

10.  With regards to the vestibular system, answer A or B for each statement:
A. Otolith organs
B.  Semicircular canals

(A or B?) Respond to linear movement and gravity and the head tilting in any         direction
(A or B?) Respond to angular movement of the head

ANSWER KEY:
1.  D

2.  B and C

3.  B

4.  False - Gravitational insecurity is one type of modulation disorder that is a fear of movement or a fear of the feet being
off the ground.  Aversive responses to movement may result in autonomic nervous system reactions (i.e. nausea, vomiting,
dizziness, etc).  The difference between the two is that gravitational insecurity is associated with decreased otolithic
vestibular processing whereas aversive responses to movement are associated with decreased processing of semicircular
canal mediated information.                

5.  False - A child may have difficulty processing the sensory input and respond hours after the initial intervention.        

6.  1. Sensory defensiveness
2. Hyporesponsive to sensory input
3. Gravitational Insecurity
4.  Aversive responses to movement

7.  Sensory defensiveness

8.  A

9.  Dyspraxia        

10.  
A.  The otolith organs respond to linear movement and gravity and head tilting in any direction
B.  The semicircular canals respond to angular movement of the head.
