Exam 6: Exstintion: Sensation and Perception

Total color blindness usually occurs when an embryo has been exposed to the rubella virus (German measles).

Different species sense the world differently.

Sense receptors convert the energy of the stimulus to:

Despite the lack of evidence of ESP,many people say they believe in it.

Sarah says that the color purple smells like a rose and the aroma of cinnamon rolls feels like velvet.Sarah is displaying the symptoms of:

Aiko invites her American friends to her home and the raw oysters,raw smoked salmon,and raw herring that she serves are well received.But when Aiko's guests notice the raw sea urchin and the raw octopus they get squeamish,even after she explains that they taste good! Explain the differences in taste preferences between Aiko and her American friends.

The tendency to perceive what you expect is called:

Eye movements cause the location of an object's image on the back of the eye to keep changing.But in the laboratory,researchers can stabilize the image of a simple pattern at a particular point at the back of the person's eye.What happens when the visual receptors are given this chance to "fatigue"?

Perception occurs when energy in the external environment or in the body stimulates receptors in the sense organs.

As she studies in the library,Beatrice is not aware of the pressure of her watchband on her wrist.This is called:

A snail-shaped,fluid-filled organ in the inner ear is called the:

Sound intensity is measured in units of measurement named after the inventor of the telephone,Alexander Graham Bell.What are these units called? Contrast the typical sound levels associated with several different environments.How can exposure to loud noises damage hearing?

Pitch is what makes a note played on a flute,which produces relatively pure tones,sound different from the same note played on an oboe,which produces very complex sounds.

As you take this test,it is unlikely that you are constantly aware that your legs are making contact with the legs of the chair.This is called:

It is extremely rare to find a species of animals that is totally color blind.

Most people who chronically have trouble tasting things have a problem with smell,not taste.

Precognition is defined as the direct communication between one mind and another without the usual sensory signals.

Principles that describe the brain's organization of sensory building blocks into meaningful units and patterns are called Gestalt principles.

What limitations of the procedures to measure absolute thresholds and difference thresholds were addressed by signal detection theory? Explain the way in which signal detection theory divides the detection of a sensory signal into two processes,giving specific details about the possible outcomes based on these processes.How would this method have a real-world application in the training of air-traffic controllers?

People having more taste buds than others are referred to as:
