Unit 6 Test Terms (Nuggets)

Question 1

Absolute Threshold

Answer 1

The smallest amount of a stimulus you can detect at least 50% of the time

Question 2

Subliminal Perception

Answer 2

Information is getting into our systems and to our brains without us truly being aware of it

(Movie theater shows quick pic of popcorn, you’ll begin to want it later on)

Question 3

Sensory Adaption

Answer 3

More exposure=Less Sensitivity (The more time you spend in cold water, you’ll get used to it)

Question 4

How does wavelength relate to color?

Answer 4

The longer the wavelength, the lower the frequency which indicates it’s color. The longest wavelength has the lowest frequency and represents the color red.

Question 5

How does amplitude relate to Color?

Answer 5

Tells you about the intensity or brightness of the light relative to other light waves of the same wavelength. It’s a measure of how much energy the wave carries

Question 6

Function of the lens

Answer 6

Focuses light on Retina

Question 7

Function of the Optic Disc

Answer 7

Optic Nerve head is the point in the eye where the optic nerve fibers leave the retina. Due to absence of light sensitive rods and cones of the retina at this point, it is not sensitive to light and thus is also known as “The Blind Spot” or “Anatomical Blind Spot”

Question 8

Relation between light and farsightedness

Answer 8

Accommodation (How the lens adjusts to light) Farsightedness (Flattens distant objects)

Question 9

Top-Down Processing

Answer 9

we form perceptions (or focus our attention) by starting with the larger concept or idea (it can even be the concept or idea of an object) and then working our way down to the finer details of that concept or idea

Question 10

Binocular Cues

Answer 10

Requires both eyes. Humans are able to see things that are both far and near, and can actually identify where those objects are in space

Question 11

Perceptual Constancy in General

Answer 11

Perception stays the same despite changing sensory input

Question 12

Three types of Color Blindness

Answer 12

Red-Green, Blue-Yellow, No Colors (Very Rare)

Question 13

Closure

Answer 13

Closure is a Gestalt principle of perceptual organization that explains how humans fill in visual gaps in order to perceive disconnected parts as a whole object. For example, can you tell what shape this elements make? [__] – answer = square

Question 14

The Blind Spot

Answer 14

Visual information travels along the optic nerve in the eye before it begins its journey to the brain for processing. There is a certain spot on the optic nerve that does not have any receptor cells (the area where the optic nerve leaves the eye), and, as a result, can’t receive information. The result is the blind spot.

Question 15

Differences between Cones and Rods

Answer 15

Cone: Color vision, Sharpness, Daylight, Inside the Fovea Rods: Black & White Vision Peripheral Vision Low light Outside the Foeva

Question 16

Gestalt is a form of

Answer 16

Perceptual Organization

Question 17

Complementary Colors

Answer 17

When mixed together they produce a neutral color, like gray. Red and green, blue and yellow, and green and magenta are complementary colors

Question 18

What is the first area of psychology to be studied?

Answer 18

Psychophysics; the study of the relationship between sensory input and the accompanying experience

Question 19

Differential Threshold

Answer 19

The point at which you notice that two stimuli are distinct from one another

Question 20

Visual Cliff Experiment

Answer 20

The Visual Cliff is a test given to infants to see if they have developed depth perception. The way it works is there is a platform that is covered with a cloth that is draped all over the place (on the platform, down to the floor, all over…). Then, a piece of glass or other clear material is placed on top of the platform and extends well off of the platform, creating a sort of bridge. An infant is then placed on the platform, and the infant’s mother stands on the other side of the clear bridge. The mother calls for the child who, if it crawls off the platform and onto the clear bridge, it does not yet have depth perception. If it stops when it gets to the edge of the platform, looks down, and either is reluctant to cross or refuses to cross, then the child has depth perception.

Question 21

Occiptial Lobe and Sensation

Answer 21

Sensation is receiving sensory input. Occitial Lobes is sight.

Question 22

The Thalamus and Senation

Answer 22

Sensation is receiving sensory input. Thalamus gatekeeper of sensory information, all but smell
