Answer 11

Depth Perception

Question 12

Skilled players - vision

Answer 12

Orient central vision towards key players

Question 13

Less skilled players - vision

Answer 13

Don’t have enough knowledge to effectively process info from peripheral vision. May use a strategy where they direct all their attention centrally, to look at key players.

Question 14

Two vision channels

Answer 14

Perception pathway (Ventral), Action pathway (Dorsal)

Question 15

Perception Pathway

Answer 15

Ventral Stream - Determines what you are looking at
Connects the primary visual cortex with the inferior temporal lobes

Question 16

Action Pathway

Answer 16

Dorsal Stream - Determines movement and movement related information
Connects the primary visual cortex with the posterior parietal lobes

Question 17

Dorsal stream location

Answer 17

Runs over the top of the brain

Question 18

Ventral stream location

Answer 18

Runs below the dorsal stream

Answer 19

Information from the environment (eg. opposition, ball, etc).

Question 20
