Final đź’• Flashcards
Three things associated with touch:
Texture, temperature and pressure
Absolute threshold
Slightest sense amount detectable
Auditory nerve
Connect Coachella to the thalamus (sound)
Cochlea
Where hearing is transduce.
Color blindness
People who have issues with their cones
Conductive deafness
Middle ear bones wear out (common)
Decibel levels
Instant damage 120 (gun shot)
Prolong damage 80-90
Whisper (0-5)
Talk (30-40)
Decibels
How volume is measured
Difference thresholds
Smallest difference detectable
Ear drum
Vibrates when sounds hits, pops under pressure
Hammer, anvil, stirrup
Three small bones that amplifies sounds
Hearing aids
Helps amplifies sounds
Iris
Muscle that dilates pupil
Cornea
Gives eye shape and clarifies
Kinesthies
Know where our body parts are
Lens
Adds distance and dimension
Loudness
Size of the wave (volume)
Occipital lobe
Vision
Olfactory bulb
Where smell is transduce
Olfactory nerve
Converts chemicals into neural messages
Optical nerve
Connects retina to the thalamus. Sends images to thalamus
Partial lobe
Touch,taste, and kin
Perception
One’s interpretation of things
Pitch
Number of waves in a sound wave
Pupil
Dilates to let light in
Retina
Where transduction occurs
Rods
Brightness
Cones
Tells us color
Sensation
Information is sent to your brain from the outside world
Sensorineural deafness
Damage to inner ear
Taste buds
Transduction for taste
Temporal lobe
Hearing
Vestibular sense
Aka “semicircular canals” tells us balance, direction, gravity and movement.
How are smell and taste related?
Smell and taste combined makes flavor
5 taste qualities
Sweet, salty, savory, sour, and bitter
Why is there a blind spot
Part of the eye where the optic nerve covers the retina. There’s no photoreceptors
How do you soundwaves work?
Sound waves vibrate through the bones and not ears transduce into neural messages
We group by
Similarity, proximity, and continuity
5 examples of gestalt perception
- change/new
*constants
*figure-ground
*closure issues
*grouping
Why does perception fail?
- Can’t understand the sensation
- We misinterpret the sensation.
Perceptional constant
We can recognize things under many different conditions and situations
Top down processing
(Concept driven processing) perceptions are guided by our brains, memory and experience
Bottom up processing
Our perceptions are guided by a sensation or stimulus
Blinding problem
How our brain uses sensory information, emotion, memory, and combines these to make a perception
Feature detectors
Area specialized in perception of our senses they glow when a perception occurs
PAG
Peri aqueductal gate
Pain travels through spinal cord to the frontal lobe center forehead
Also known as anterior cingulate cortex
Most sensitive body parts
Armpits, sex organs and arch of feet
Most strongest
Heel foot, knees and elbows shoulder blades
