Question 1

Visual receptors that respond to dim light are called cones.

Accepted Answer

A) True 
 B)False

Question 2

In sensory deprivation studies, researchers were interested in what would happen if our senses adapted to most incoming stimuli. Explain the findings of the early studies in sensory deprivation. What has been revealed by later research?

Accepted Answer

A good answer will include the following key points.
-In early studies of sensory deprivation, researchers isolated male volunteers from all patterned sight and sound.
-Within a few hours, most of the men felt edgy and many were so disoriented that they quit the first day.
-Those subjects that continued became confused, restless, and grouchy, and many experienced hallucinations.
-Later research, using better methods, showed that hallucinations are less frequent and less disorienting than had first been thought.
-Some perceptual and intellectual abilities may actually improve.
-The response to sensory deprivation depends on expectations and interpretations.
-Those who voluntarily engage in limited periods of sensory deprivation may find it to be relaxing.

C)   a person's response depends on the stimulus and on a decision about it.
D)   people will always be biased toward thinking the stimulus was there, even if it wasn't.

Question 12

How have researchers shown that a simple visual stimulus can affect a person's behavior? What has research revealed about subliminal persuasion?

Accepted Answer

A good answer will include the following key points.
-Subliminal perception refers to the ability of a stimulus that we are not aware of to affect our behavior.
-Non-conscious processing of sensory stimuli does occur.
-Studies demonstrate that subliminal perception can have an effect on our behavior.
-Such non-conscious processing appears to occur not only in perception, but also in memory, thinking, and decision making.
-Subliminal persuasion refers to the ability of subliminal stimuli to manipulate a person's attitudes and behavior.
-Most attempts by scientists to demonstrate subliminal persuasion have been unsuccessful.
