Vision
What part of eye controls the size of the pupil?
Iris
What is the more official name for hearing?
Audition
What is the official name for smell?
Olfaction
After a rough collision on the soccer field, a player is clutching their bruised shin in pain. The athletic trainer runs over and firmly presses a cold chemical ice pack against the injury. Within moments, the player feels a significant decrease in the sharp throbbing sensation, even though the bruise itself hasn't healed yet.
Gate control theory
Perceptions are built/based on ________.
Experiences
Which part of the eye is the transparent, protective outer layer that helps focus incoming light as it first enters the eye?
Cornea
Which part of the ear sends information to the brain?
Cochlea
What do supertasters have that medium and nontasters don't?
more taste receptors
Which part of your body sends messages to your brain for your vestibular sense?
Inner ears
You’re sitting in a completely silent room, and your friend begins to slowly turn up the volume on a radio from zero. For the first few seconds, you hear absolutely nothing. Suddenly, at a very specific volume notch, you can just barely detect the faint sound of music.
Absolute threshold
Located in the center of the retina, the fovea is responsible for our sharpest central vision. Which photoreceptors are most densely packed in this area, and what is their primary function?
Cones- color and detail vision
What types of sounds do you hear due to temporal coding?
Low pitches
The olfactory (smell) part of the brain is located close to two parts of the limbic system. This explains why smell is so closely tied to emotion and memory. Which two specific parts of the limbic system is the olfactory close to?
Hippocampus (memory), Amygdala (emotion)
After losing his left hand in an accident, an athlete occasionally feels a sharp, localized cramp in his non-existent thumb.
Even though the physical limb is gone, his brain’s sensory cortex continues to receive signals or misinterpret activity from neighboring neural areas, leading him to perceive physical sensations where his hand used to be.
Phantom Limb Sensation
You walk into your friend’s apartment and are immediately hit with the powerful, overwhelming scent of a "Pumpkin Spice" scented candle. However, after about fifteen minutes of chatting on the couch, you realize you can’t smell the candle at all anymore, even though it’s still burning right next to you.
Sensory adaptation
Put the following parts of the eye in sequential order.
lens, optic nerve, retina, blindspot, cornia, iris/pupil
cornea, iris/pupil, lens, retina, optic nerve
The rods and cones of the retina is to vision as the ____________ of the _________is to hearing.
hair cells, cochlea
While practicing yoga, you close your eyes and are still able to tell exactly where your arms are positioned in relation to your torso. Which sensory system is primarily responsible for this awareness?
Kinesthesia
You are looking at a highly pixelated image. At first, you only see random squares of color, but as you continue to look, your brain slowly assembles these individual pieces into the shape of a dog. Which type of processing are you primarily using in those first few moments?
If you are standing in a dark room and trying to see a very faint, dim star through a window, you will often have better luck seeing it if you look slightly to the side of the star rather than looking directly at it. Based on the distribution of photoreceptors, why does this "averted vision" work?
A) Looking to the side shifts the light onto the fovea, which contains the most rods.
B) Looking to the side allows the light to fall on the peripheral retina, where rods (which are more sensitive to low light) are concentrated.
C) The blind spot is located in the center of the eye, so looking to the side moves the image onto the retina.
D) Cones require more light to fire, so looking directly at the star in the dark actually makes it disappear.
B
What is the 60/60 rule of hearing?
listen to music at a max of 60% voluen for only 60 minutes at a time to avoid damage to ear structures.
Which two taste receptors are used when you eat sour patch kids?
Sweet, Sour
During a "Sensory Awareness" lab, a student is blindfolded and asked to perform two tasks:
Task A: Hold their arms straight out to the sides and then touch their index fingers together in front of their chest.
Task B: Stand on one leg and try to keep their head perfectly level while the floor beneath them starts to tilt slightly.
Task A: Kinesthesia
Task B: Vestibular
You are a participant in a psychology study. The researcher puts you in a dark room and does two things:
First, they slowly increase the brightness of a tiny light bulb until you can just barely see it.
Later, once the light is clearly visible, they slightly increase the brightness again and ask you to tell them the exact moment you notice it has become brighter.
Which concept is being tested in the first part of the study (barely seeing the light)? Which concept is being tested in the second part (noticing a change)?
Absolute threshold, difference threshold
