Visual Perception Flashcards

Flashcards on Visual Perception

Color performs many different __ , and we use it to construct visual perception in a variety of different ways.

Classify objects, facilitate perceptual organization, and help search for food.

Color is not actually a property of the world, it's a __.

Property of minds

We're simply perceiving the __.

Electromagnetic radiation wavelength that is not absorbed by the object

Color isn't a property of vision in itself. It's made up of three main perceptual qualities, and these are __.

Hue, saturation, and brightness

The hue of an object is determined by the __.

Wavelength of light that it reflects

Hue is the __.

Dominant wavelength of light that is reflected back at you

White happens when __.

An object itself doesn't absorb any wavelengths of light

__ is gonna be perceived as blue.

A short wavelength around 400 nanometers

Saturation refers to the __.

Intensity of color of color in a stimulus

Brightness refers to the __.

Amount of pure white light in a stimulus

Young and Helmholtz assumed that there is __ different receptor mechanisms that are responsible for our color vision.

Three

Participants were asked to __.

Adjust each of these nanometer lengths until it matched the color within the test field

This led them to conclude that there was __.

Three photoreceptors

Metamers is the idea that __.

The colors, although physiologically are not equivalent, perceptually, they are equivalent for us

Three cones that responded to three different kinds of wavelengths: __.

Short, medium, and long

Some females have four different kinds of cones in their photoreceptors, which results in a much more rich and complex perception of color, this is an example of __.

Tetra chromatic vision

White is gonna be __.

All of your cones firing at the same time
