Week 2

Question 1

Define visual dominance

Answer 1

The tendency forvisualinformation to determinewhat isperceived when there is a conflict between thevisualinformation and information from another sensory

Question 2

Explain titchener circles illusion

Answer 2

• In thisillusion, two identical discs can be perceived as being different in size when one is surrounded by an annulus of smallercirclesand the other is surrounded by an annulus of largercircles

Question 3

what are the two stages of movement as stated in the woodworth study

Answer 3

1. Initial impulse (preprogrammed)

2. Current control (visual feedback)

Question 4

Define Impulse variability model

Answer 4

The impulse-variability theory maintains that as the distance from a target increases, more force must be exerted, leading to a greater variability in movement trajectory, decreasing the chances of hitting the target.

Question 5

What does the iterative corrections model state?

Answer 5

• Feedback from one movement is used perform the next submovement etc.

Question 6

Basic assumption of the impulse variability model

Answer 6

All movements characterised by variability

Question 7

Basic observation of the impulse variability model

Answer 7

Force and force variability are related, duration and duration variability are related

Question 8

impulse = ?

Answer 8

Change in momentum

Question 9

Momentum = ?

Answer 9

Mass x velocity

Question 10

Define Transport phase

Answer 10

Hand is carried towards object

Question 11

Define Grasp phase

Answer 11

Fingers wrap around object

Question 12

Motion provides critical …….?

Answer 12

Visual cues

Question 13

catching a ball requires?

Answer 13

Coincident timing skills which require anticipation

Question 14

Information received from the environment is not perceived as meaningful until…..?

Answer 14
