Unit 5 Sensation & Perception

Receptors that are responsible for transferring light into neural impulses.  

• Rods & Cones of Retina
• Optic Stem
• Cornea
• Iris

A principle that states, for any change in a stimulus to be detected, a constant proportion of that stimulus must be added or subtracted.  

• Gate-Control Theory
• Weber's Law
• Difference Threshold
• Multiple constant 

Smell is transmitted to the brain via the.....

• Optic Nerve
• Olfactory Nerve
• Auditory (chochlear nerve)
• Sensory Nerve

This theory states that we can lessen some pains by shifting our attention away from pain impulses.  

• Pain perception method
• Gate-Control Theory
• Acute sensation deprivation
• Theory of relativity

The organization of sensory information into meaningful experiences.  

• Senstation
• Perception
• Gestalt Awareness
• Sensory organization

The weakest amount of a stimulus that a person can detect half of the time.  

• Differnce threshold
• Absolute threshold
• Gate threshold
• Subliminal message

This system controls the balance of the body.  

• Vestibular System
• Kinesthetic System
• Vision system
• Internal system

In the human eye, rods are to _________, as cones are to ________.

• light/ color

• color/ light

• monochromat/ dichromat

• dichromat/ monochromat

• lens/ iris

The phenomenon of color constancy best demonstrates that...

• an object's perceived color is influenced by its surrounding objects

• the retina has three types of color receptors

• the brain processes information about color and shape simultaneously

• quivering eye movements help to maintain the perception of color

• color vision depends on pairs of opposing retinal processes

Almost half the birds in the tree outside Brian's window were brown and the rest were red, so Brian perceived them as two different groups of birds. This best illustrates...

• proximity

• closure

• similarity

• connectedness

• disparity
