Q

What is the visual system

A

Perceptual stimuli Hey that contains distal stimulus which is the actual object and proximal stimulus which is the information registered on your sensory receptors

Q

What is the special mechanism approach

A

Concept that humans are born with a specialized device that allows us to decode speech stimuli

17
Q

What is General mechanism approach

A

Argues that we can explain speech perception without proposing any special phonetic module

18
Q

What is viewer centered approach

A

Proposes that we store a small number of use of 3-D objects rather than just one View

19
Q

What is a template

A

Specific patterns that you have stored in memory it then notes which template matches the stimulus
