Identify a binocular depth cue

convergence

or 

retinal disparity

200

Name a pictorial depth cue

height in visual field

relative size

interposition

texture gradient

linear perspective

300

This depth cue enables us to perceive distance as objects with more texture are interpreted as closer than objects with less texture

texture gradient

400

Closure

300

They refer to the way we organise features of a visual scene to group parts together to make a whole or complete image. 

The visual process

The first part of the process for visual perception

Reception (stimulation)

200

The area of space in which a receptor can respond to a stimulus

receptive field

300

The process by which the receptors change the energy (light- electromagnetic energy) to a form for neural transmission

Transduction

400

The process of making sense of the visual stimulus

interpretation

500

What is the difference between sensation and perception

Sensation is physical and is the same fro everyone

Perception is psychological and is unique to the person

Factors affecting perception

100
