Midterm (101-110)

Question 1

feedforward control system

Answer 1

motor commands are instantiated as preplanned trajectories that are executed by the articulatory system in a time-locked manner

Question 2

feedback control

Answer 2

motor commands are calculated and issued online during movement rather thanking pre-planned

Question 3

somatosensory feedback

Answer 3

tactile info, kinesthetic info, you feel your lips pressing together …

Question 4

auditory feedback

Answer 4

feedback gotten from actually hearing you utterance

Question 5

Dental prosthesis experiment (Jones & Munhall 2003)

Answer 5

adaptation to teeth enlargement during /s/ in tas with and without auditory feedback

1. if subjects compensate with auditory feedback; would support hypothesis of an acoustic representation of speech task
2. if subjects compensate without auditory feedback; would rather support an articulatory representation of speech production task

Question 6

results dental prosthesis experiment

Answer 6

better compensation when auditory feedback; but once compensation was initiated also improvement without AF

Question 7

open loop control

Answer 7

control action from the controller is independent of the “process output”

Question 8

closed loop control

Answer 8

control action from the controller is dependent on feedback from the process in the form of the value of the process variable

Question 9

closed loop control system

Answer 9

a control system possessing monitoring feedback, the deviation signal formed as a result of this feedback being used to control the action of a final control element in such a way as to tend to reduce the deviation to zero

Question 10

speaking-induced suppression

Answer 10

phenomenon that the sounds one generates by overt speech elicit a smaller neurophysiology response in the auditory cortex than comparable sounds that are externally generated (specific example of self-suppression)
