L4C: Information Processing Stages - Response Programming

Question 1

Answer 1

C. Reaction Time would decrease

Question 2

Answer 2

B. response selection

Question 3

3. If we knew that someone’s RT for a 1 choice RT was
   250ms and for a 2 choice RT was 400ms, using Hick’s
   Law, what would be their 4 choice RT?

Answer 3

550ms

Question 5

What does it mean for a movement to be complex?

Answer 5

Complexity:

• More components
• Higher precisions demands (accuracy)
• Longer movements (duration)

Question 6

How is RT affected by Movement Complexity?

Answer 6

If a set of motor commands for a movement is prepared in advance of response initiation, then movements of greater complexity should take longer to prepare

RT should increase as movement “complexity” increases

Question 7

Movement complexity affects RT
