HKR 3300 Final Exam Questions And
Answers |Latest 2025 | Guaranteed Pass.
Speed-accuracy trade-off - Answer✔when both speed and accuracy are essential to perform
the skill; i.e., when speed is emphasized, accuracy is reduced and vice-versa
Fitt's Law - Answer✔a human performance law specifying the movement time for an aiming
movement when the distance to move and the target size are known
open-loop control - Answer✔process that occurs at movement initiation and moves limb into
the vicinity of the target; without feedback
closed-loop control - Answer✔process that occurs at movement termination in which feedback
from vision and proprioception at the end of movement ensure target is hit accurately
preparation phase - Answer✔movement phase in which the regulatory conditions of
environmental context are assessed
initial flight phase - Answer✔movement phase in which we monitor limb displacement and
velocity; shift gaze to keyhole at 50% time-to-contact
termination phase - Answer✔movement phase in which we provide spatial-temporal info to
correct movement accuracy errors to ensure target is reached

prehension - Answer✔general term for actions involving reaching for and grasping of objects;
three components: transport, grasp, object manipulation
reflex chain - Answer✔a neural network that controls a sequence of responses based on the
sensory feedback provided by each element in the sequence
half-center hypothesis - Answer✔hypothesis by Graham Brown stating that the spinal cord
possessed spinal centers capable of intrinsically instigating flexor and extensor movements
without descending and/or sensory input
central pattern generators (CPG) - Answer✔neural mechanisms in the spinal cord that produce
rhythmic alternating activity in the extensor and flexor motorneurons (locomotion)
accomplished by phasic barrages of excitatory and inhibitory inputs to motorneurons
Spontaneous gait transitions - Answer✔an important motor control characteristic of
locomotion in which people spontaneously change from walking to running gait (and vice-
versa) at critical speed
action preparation - Answer✔the activity that occurs between the intention to perform an
action and the initiation of that action; sometimes, the term motor programming is used to
refer to this preparation activity
reaction time - Answer✔the amount of time taken to respond to a specific stimulus
(preparation time)
Hick's Law - Answer✔a law of human performance stating that RT will increase logarithmically
as the number of stimulus-response choices increases
precue - Answer✔an advance indication that a specific upcoming event will require a response
