|
the premotor cortex is ________ to the primary motor cortex |
Rostral |
|
|
the basal ganglia and cerebellum are to important subcortical components of the: |
Motor system |
|
|
the cerebellum is ____ to the basal ganglia |
posterior and inferior |
|
|
is conscious control (inhibition of a flexion reflex possible? |
YES: if intention not to respond was prepared in advance, so that a signal could be sent to the reflex pathway in the spinal cord before the stimulus occurred, thus inhibiting the reflex when the stimulus did occur |
|
|
FITTS LAW experiment: targeting 3 different coloured circles of same size and same distance from white circle. Text says time to target each colour of circle should be identical. Were my times identical? Why? |
No: movement times are variable, and so the chances that three average times from a small number of trials will be identical is very small. |
|
|
According to Fitt's Law: 1) time to move to a target ____ as the distance to the target gets longer. 2) time to move to a target ____ as the width of the target gets larger. |
1) increases, 2) decreases |
|
|
According to simplified version of Fitt's Law, if participant is reaching for a target whose center is 39 cm away, and target is 5 cm wide, how long will it take? |
3.14 |
|
|
Fitt's Law: would a person be faster to move their cursor on the computer screen to a button X, which is 10 cm away and 2cm wide, or to button Y, which is 30cm away and 6 cm wide? |
Same time for both |
|
|
Based on Fitt's Law, if designing a keyboard, how should you design the keys that are used most often in order to increase typing speed? |
Make them bigger and/or closer to the resting position of the fingers |
|
|
What is Fitt's Law |
The time to acquire a target is a function of the distance to and size of the target. |
