Unit 4 Sensation and Perception

In signal-detection theory, if a subject detects a stimulus when no stimulus is present we call it 

• hit
• miss
• false alarm
• correct rejection

Subliminal means

• below threshold
• barely there
• deceptive
• superimosed

You notice a distinctive smell when you enter the room. After a few minutes you no longer notice the smell. What explains this?

• progressive learning
• sensory contraction
• sensory novelty
• sensory adaptation

The amount of light entering the eye is regulated by changes in the size of the 

• pupil
• lens
• cornea
• retina

The blind spot is

• where the photo cells bleach the image
• the point where the ganglion connects to the bipolar cells
• where the optic nerve connects to the retina
• what leads to color blindness

Hering's opponent-process theory suggest that receptors where linked to what colors?

• red-yellow, blue-green, black-white
• red-green, yellow-blue, black-white
• red-black, yellow-white, green-blue
• yellow-green, red-blue, black-white

If we process information from small individual concepts to a larger whole we are doing

• bottom-up processing
• bottom-down processing
• bottom-top processing
• top-to-bottom processing

The successive blinking on and off of the lights on a neon sign gives the impression that a drink is filling a glass. This illusion of motion is the

• phi phenomenon
• constancy 
• proximity
• motion parallax

Paints that lead to ambiguous interpretations often invert the

• figure and ground
• sensation and percpetion
• top and bottom
• open and closed processing

Proximity refers to

• objects near each other are seen as a unit
• similar objects are a unit
• cells fire faster when near each other
• common goals draw them closer
