Open, Closed, & Schema Theory Flashcards
closed loop theory
- feedback is going back at the body
- individual compares accuracy of the movement to the template of the intended action
- when difference is perceived, correction is made
closed loop theory uses _______________ and ___________________ feedback to monitor and shape new behavior during acquisition
proprioceptive and sensorimotor
open loop theory
movement can take place without sensory feedback
an example of partial loop would be
if a patient looses their hearing
schema theory
abstracted memory that is built up by doing the same movement over and over
what is the generalized motor program
a motor template that specifies sequence of actions, timing, duration, force, etc.
steps of the generalized motor program
- information about initial conditions (what is the body doing)
- motor parameters from previous memory traces (how much skill does the person have?)
- sensory consequences of movement
what are the two types of memory relative to schema theories?
recall memory & recognition theory
recall memory
production of movement, allows person to make movement
recognition memory
memory individual uses to assess accuracy of movement performed
what if your patient is using pressed, effortful phonation?
use exercises to decrease the stress- jaw release
with each repetition of the jaw release movement, the patient will form a
memory trace
more traces become available of the jaw release practiced, so that it becomes
more natural and happens on its own
in voice therapy, recognition schema will look like
the patient being able to self correct the voice they produced in your exercises
eventually you want the patient to be able to discriminate between
effort and ease and effortful posture
