17
Q

are very rapid
may not require conscious attention
are mediated at the spinal level

A

reflexive corrections

reflexive closed loop control

18
Q

kinds of reflexive corrections

A

myostatic

long-loop

19
Q

slower than reflexes but faster than reaction time
the response does not have to occur in the stimulated muscles but can involve a number of muscles and joints, resulting in a smooth, coordinated response
seems to relate to a purpose of the completion of some predetermined action
influenced by practice
mediate by some stage of info processing
probalby remains at a nonconscious level

A

an intermediate response for error correction: the triggered reaction
