Section 4

Question 1

what are the cognitive factors that affect reaction time and movement

Answer 1

• anticipation
• attention
• anxiety
• hicks law
• psychologically refractory period

Question 2

what is multitasking and how does it affect movement?

Answer 2

when 2 task are performed at the same time
- if they both require the same amount of attention, then performance diminishes in both

Question 3

what is a dual task paradigm

Answer 3

it is when there is a primary task and secondary task
- primary task is usually motor related
- secondary task can be continuous or discrete

Question 4

how do interpret the results of the dual task paradigm

Answer 4

look at the moments of graphs when tracking is poor and it is usually due to more attention to motor task after being perturbed

Question 5

what is anticipation and the types?

Answer 5

being prepared for what and when the stimulus is
- effector anticipation
- temporal anticipation

Question 6

explain how anticipation occurs when someone is about to walk on an slippery terrain instead of an stable one

Answer 6

it changes the way someone moves in their current situation

when someone knowingly walks on a slippery surface, they decrease the angle of their footing and use less force compared to someone unknowingly walking on a slippery surface.

Question 7

explain effector anticipation

Answer 7

a person figuring out how long it takes to motor plan and perform their on movement

Question 8

explain temporal anticipation

Answer 8

the ability to anticipate when a stimulus will occur is dependant on
- foreperiod regularity: knowing the duration between each stimulus
- for period duration: too short of a duration leads to increased reaction time and too long leads to increased reaction time or decreased reaction time depending whether the catch trial is present (withholding the stimulus)

Question 9

what is attention?

Answer 9

the information processing capacity
gaze and attention usually go hand and hand

Question 10

how does arousal and anxiety affect reaction time?

Answer 10

performance is best at optimal amount of arousal and some anxiety as it makes you pay more attention to you actions

Question 11

what are the 3 stages of central processing?

Answer 11

• stimulus identification
• response selection
• response programming

Question 12

what is hicks law?

Answer 12

the relation between choice reaction time and the number of stimulus-response alternatives

Question 13

what does hicks law show?

Answer 13

that increasing the amount of SR alternates increases choice reaction time but in a smaller amount
