It is how our brain interprets the distances and positions of objects in the world around us, helping us understand how close or far things are from us.

Depth dimensions.
Distance.
Height.
Width.

Size cues.
Height cues.
Study the rest.
What are some binocular cues?
Convergence.
Retinal disparity.
What is perceptual constancy?
It is what allows people to change and move around from known to unknown situations and still perceive many things as stable and the same.
What are some visual constancies used to explain stable visual perception?
Size constancy
Shape constancy
Brightness constancy
Colour constancy
Location constancy
What is the perception of movement?
It is an area where visual perception is sometimes inconsistent, because information from the retina and eye muscles may play
tricks on people.
What are the types of perception movement?
Real Movement.
Apparent movement.
Stroboscopic movement.
Auto-kinetic illusion.
Induced movement.
What are visual or optical illusions?
It is the difference between the appearance of visual stimuli and physical reality.
What are physical illusions?
They are illusions caused by real stimulus attributes.
What are induced illusions?
It is when people experience something that does not happen.
What are optical illusions?
They are illusions that are caused by stimuli playing tricks on the mind, leading to inaccurate perceptions.
