Senses
Gustation
What is the sense of taste?
The PROCESS by which we DETECT a physical stimulus and code that energy into neural signals.
What is sensation? Note: The process through which physical energy is CONVERTED into an electrical charge is known as TRANSDUCTION.
The process of how we select, organize and interpret information from our senses.
What is perception? Note: Our perceptions are influenced by our EXPECTATIONS or preconceptions, known as our PERCEPTUAL SET.
If you increase the amplitude of a sound wave, it also increases this.
What is volume? Note: When you increase the volume, the amplitude or height of a sound wave increases. Note: Frequency refers to the number of waves in a cycle, or pitch.
The smallest bones in our bodies are located here.
What are our ears?
The light sensitive inner surface at the back of the eye which contains rods and cones.
What is the retina? Note: The rods and cones are the receptors of vision. Cones allow us to see colors, while rods allow us to see variations in light. The OPTIC NERVE carries the information from the receptor cells to the corresponding area of the brain. Where the OPTIC NERVE joins the retina, you have no receptor cells; this is your BLIND SPOT.
The basic taste sensation that is related to foods such as soup, cheese, chicken, and MSG.
What is "umami"?
The tendency to perceive images as complete objects and overlook gaps.
What is closure?
While lying in bed, Zac Efron asked his wife, Serena, to turn up the television. Even though she did increase the volume, Zac said, "Aren't you going to turn it up?" Clearly, the amount Serena ADDED to the volume, did not exceed this threshold for Zac.
What is the difference threshold (or just noticeable difference)?
According to this law, a person organizes a stimulus into the simplest possible form.
What is the law of pragnanz?
The receptor cells of olfaction are located here.
What is the top of the nasal cavity? Note: Dogs have a much keener sense of smell than humans because they have more receptor cells and a lower absolute threshold.
The process in which sensory receptor cells become less responsive to an unchanging stimulus.
What is sensory adaptation? Note: This happens when you jump in a cold lake, walk into a pig barn, into a cupcake shop, or while your glasses sit on your face.
A stimulus that is important or interesting to a person to pull their attention.
What is a pop-out stimulus?
Dr. Shaw wants to determine the SMALLEST or LIGHTEST amount of pressure or touch that can be felt by children when they are sleeping. She is interested in finding THIS.
What is the absolute threshold? Note: The absolute threshold is the smallest quantity of physical energy that can be reliably detected by an observer.
This chemical substance can trigger AGGRESSION, SEXUAL AROUSAL, and TERRITORIAL BEHAVIOR when in other members of that species, but does NOT apply to humans.
What are pheromones? Note: There has been NO credible proof that pheromones have any effect on human beings whatsoever.
This is how the images are projected onto our retina.
What is upside down?
When you think of sensation and perception, you think of your home mail service. When the mail is delivered to your home, the postal worker puts it in your mailbox. You then take it inside, deciding which is junk. In this scenario, the MAILBOX is analogous to this?
What is the sensory system?
Prosopagnosia is a visual disorder that impairs an individual's ability to recognize faces and would have to do with damage to THIS area of the brain.
What is the fusiform face area?
A MALFUNCTION IN THE CENTRAL NERVOUS SYSTEM that creates a negative feeling that may be triggered by an injury or disease.
What is neuropathic pain? Note: A common example of neuropathic pain is phantom limb pain. Note: A negative feeling caused by an external stimulus is referred to as nociceptive pain.
Phenomenon of selective attention which allows a person to concentrate on one voice and ignore many others.
What is the cocktail party effect?
Specialized nerve endings that provide a constant stream of information to the brain from our muscles through our spinal cord and onto the cortex of the parietal lobe.
What are proprioceptors?
When you think of sensation and perception, you think of your home mail service. When the mail is delivered to your home, the postal worker puts it in your mailbox and you take it into your house, deciding which is junk. In this scenario, the DELIVERY of the mail to your mailbox is analogous to this.
What is sensation?
The process whereby the brain is able to process many things at the same time, such as when it breaks down vision into separate dimensions such as form, depth, movement, and color, and works on each aspect simultaneously.
What is parallel processing?
This chemical inhibits the transmission of pain signals to our brain.
What are endorphins? Note: This is the chemical in the body that explains why you don't always feel pain as soon as you injure yourself.
The vestibular sacs, which help us maintain balance, are located here.
What are our ears?
