16
Q

What is linear perspective?

A

The apparent convergence of parallel lines on the horizon

17
Q

What is a texture gradient?

A

Objects at a distance are denser and less detailed

18
Q

What do distance objects look like in an aerial perspective?

A

Distant objects are fuzzy due to moisture and particles in the air.

19
Q

What happens when an object occluded another

A

It appears to be closer

20
Q

What is the muller lyre illusion?

A

Depth cues suggest the long line is closer.

21
Q

What is the ponzo illusion?

A

Linear perspective suggests objects are further away.

22
Q

What is the Ames room illusion?

A

Depth cues suggest people are the same distance from the observer

23
Q

What three cues allow us to locate objects using auditory perception?

A

The difference in intensity of sound in the two ears
The overall intensity of the sound
The difference in time it takes to reach difference ears

24
Q

Why do stable objects remain stable if the observer is moving?

A

Our perceptual system compensated for voluntary eye movements

25
Q

How do we perceive motion?

A

Distinguish between the object and observer moving
Using the intensity of sound

26
Q

What is apparent motion?

A

When our perceptual systems fill in the gaps on motionless images.

27
Q

What is the phi phenomenon?

A

Motion perceived due to the succession of flashing lights

28
Q

What happens if an object is near a stationary one

A

It induces motion

29
Q

What is the motion after effect?

A

After moving forward for some time then stop everything outside seems to be moving backwards.

30
Q

What are bottom up processes used as in feature analysis

A

We look at the features before perceiving a whole

31
Q

What does Gestalt top down processes assume

A

The whole is greater than the sum of parts

32
Q

What are organising principles used to form Gestalt?

A

Figure/ground distribution and grouping principles.

33
Q

What are some grouping principles in sound perception

A

Proximity
Good continuation
Closure

34
Q

What is gestalt often accompanied by?

A

An AHA! Moment
