Concept Check - Principles of Sensation and Perception

Sam accurately identified tones ranging from 40 Hz - 18,000 Hz more than 50% of the time. For Sam, a tone of 40 Hz represents

• The JND, or just noticeable difference

• The absolute threshold

• A subliminal stimulus

• Extrasensory perception

Sam accurately identified tones ranging from 40 Hz - 18,000 Hz more than 50% of the time. For Sam, a tone of 20 Hz represents

• Selective attention

• The absolute threshold

• The difference threshold

• A subliminal stimulus

The process by which we select, organize, and interpret sensory information in order to recognize meaningful objects and events is called

• sensation

• perception

• inattentional blindness

• parallel processing

Because she was focused on listening to the news on the radio, Mrs. Nguyen didn't perceive a word her husband was saying. Her experience best illustrates

• choice blindness

• sensory adaptation

• selective attention

• top-down processing

According to Weber's Law, if the just-noticeable difference for a 10-ounce weight is 1 ounce, the just noticeable difference for an 80-ounce weight would be ________ ounce(s).

• 8

• 4

• 2

• 1

Which of the following is an example of sensory adaptation?

• Becoming increasingly irritated at the continuous sound of a dripping faucet

• Developing an increased sensitivity to salt the more you use it in foods

• Finding the cold water of a swimming pool more tolerable after you’ve spent a few minutes in it

• Being unable to recognize that a car has swerved into your lane and is about to cause a head-on collision

When carrying a 100-pound backpack, Paige is only able to detect that the back as gotten heavier after adding a 10 pound weight. In this case, 10 pounds represents her

• Difference threshold

• Stimulus generalization

• Sensory adaptation

• Maximal threshold

________________ refers to how the physical characteristics of stimuli influence their interpretation.

• Top-down processing

• The cocktail party phenomenon

• Perceptual sets

• Bottom-up processing

The differences in the interpretation of the image above between Westerners and rural Africans can be explained by

• The cocktail party phenomenon

• Change blindness

• Differences in signal detection

• Differences in perceptual sets
