OPT471 Light & Color Perception

Below is the interdependent movement system EXCEPT

• Image-retina movement system

• Eye-hand movement system

• Eye-head movement system

The picture above is the image of

• Superior colliculus

• Optic chiasm

• Lateral geniculate Nucleus (LGN)

Parvocellular cells is also known as ........... system

Magnocellular cells is responsible for

• Movement perception

• Temporal perception

• Color perception

First-order motion perception involves

• Contrast changes on the retina

• Luminance changes on the retina

• Color changes on the retina

This is an example of...

Temporal vision is..

• Distance-related vision

• Luminance-related vision

• Time-related vision

The two basic stimulus parameters for a sinusoidal temporal stimulus are EXCEPT

• Temporal gratings

• Temporal contrast

• Temporal frequency

Temporal Modulation Transfer Function (TMTF) is analogous to ........................ in spatial vision

• Critical flicker fusion frequency (CFF)

• Contrast sensitivity function (CSF)

The above picture is the example of

• Decreased sensitivity at low temporal

  frequencies

• Decreased sensitivity at high temporal

  frequencies
