Sensation and Perception Quiz

What does sensation provide information to?

• The Nervous System

• The Conscious Mind

• The Sensory Organs

• The Environment

What is perception?

• The automatic stimulation of our senses

• The interpretation of sensory information

• The physical energy that meets our senses

• The weakest amount of stimulus that can be sensed

Where are sensory receptors located?

• Only in the brain

• In sensory organs such as the eyes, ears, and elsewhere in the body

• Exclusively in the eyes

• On the skin surface only

What is the absolute threshold?

• The strongest stimulus that can be sensed

• The minimum amount of difference that can be detected between two stimuli

• The point where something becomes noticeable to our senses

• The interpretation of what we take in through our senses

What does the difference threshold refer to?

• The weakest amount of stimulus that can be sensed

• The amount of change needed for us to recognize that a change has occurred

• The processing of sensory information into meaningful data

• The automatic stimulation of our senses

What theory explains our ability to focus on certain stimuli while ignoring others?

• Absolute threshold theory

• Sensory adaptation theory

• Signal detection theory

• Difference threshold theory

What does Signal Detection Theory suggest about distinguishing sensory stimuli?

• It is based solely on the strength of the stimuli.

• It depends on mood, attitude, and setting as well as the strength of the stimuli.

• It is determined by the sensory adaptation process.

• It is influenced only by environmental changes.

What is sensory adaptation?

• The process by which we become less sensitive to unchanging stimuli.

• The adjustment we make to changing stimuli.

• The tendency to perceive an object as being of one size.

• The ability to perceive an object as having a constant shape.

Which of the following is NOT one of the four types of constancies mentioned?

• Size

• Shape

• Brightness

• Texture

What is size constancy?

• The ability to perceive an object as having a constant size regardless of its distance from us.

• The tendency to perceive an object as changing size with distance.

• The process by which we become more sensitive to size variations.

• The adjustment we make for the size of objects that interrupt our perception.
