Newborns: survival reflexes stimulated by touch such as,
-enables them to turn their face toward milk bearing nipple
-start bonding w/parents
-feel calmed by warm/soft blanket when falling asleep
Provides sense of touch
Recieves info re:touch from receptor cells in the skin
Provides info re: light touch, pressure, vibration, temp, and pain
(consists of a protective system and a discriminative system which allows for a well balanced tactile system)
Feedback from touch receptors are needed for development of
BODY AWARENESS (where are body is in space) and
MOTOR PLANNING abilities
Alerts us when in contact with something that may be dangerous and triggers the body to react.
Dominant over Discriminative system in early life
We rely on this system to remain ready to respond to any potential threats
*May activate "fight or flight" response
Enables us to feel the quality of the item we are touching.
Dominant over Protective system once our nervous system matures
We rely on this system as a vital transmitter of info
Provides detail about touch
-excessively registers touch input
-unable to inhibit/screen out touch sensations
-often described as "tactile defensive" (protective systems working overtime)
-many touch sensations are regarged as threatening and avoided
-behavior: anxious, controlling, agressive, unwilling, inflexible
- (to control touch input)
frequent "fight or flight" responses consuming a lot of energy, leaving little energy for learing and interaction
-low arousal levels
-may only register intense touch sensations
-doesn't recieve appropriate feedback about where/how they're being touched which interferes w/development of body awareness and motor planning
-poor tactile discrimination
-hard to manipulate objects
-BIG safety concern
-seeks out excessive touch sensations
-delayed reaction to touch.
