Unit 4 Revision Flashcards
Psychophysics
- study of the relationship between stimulus and sensation (how people perceive things in the world around them)
Parapsychology
the study of paranormal phenomena including ESP and psychokinesis
clairvoyance
percieving remote events
precognition
percieving future events
Short Wavelength
- high frequency (bluish colors)
- high pitch
Long Wavelength
- low frequency (reddish colors)
- low pitch
big amplitude
bright and loud
small amplitude
dull and quiet
rods
- more than cones
- periphery
- highly sensitive in dim light
- black and white
- not detail sensitive
cones
- less than cones
- center of vision
- low sensitivity in dim light
- colors
- detail sensitive
accommodation
the process by which the eye’s lens changes to focus near or far objects on the retina
fovea
central focal point in the retina, around which the eye’s cones cluster
blindspots
lost information is filled in by brain based off of the surroundings
blindsight
ability to respond to visual stimuli w/o consciously perceiving them
binocular cues
retinal disparity
moon illusion
moon looks bigger when closer to the horizon than high in the sky
cilia
found on tips of hair cells, vibrating structure
conduction hearing loss
caused by damage to the mechanical system in middle ear that conducts sound waves to the cochlea. the waves never reach teh cochlea.
- hearing aids
sensorineural hearing loss
caused by damage to the cochlea’s receptor cells in inner ear or to the auditory nerve.
- cochlear implant
place theory
- high frequencies
the basilar membrane of the ear has different regions or areas which are stimulated depending on the frequency of the sound it receives.
frequency theory
a sound heard is replicated and matched by the same amount of nerve impulses that are then transmitted to the brain.
volley principle
neural cells alternate their firing
skin sensations
pressure, warmth, cold, and pain
olfactory bulb
sends smells to amygdala and hippocampus
kinesthesia
kinesthetic sense has to do with sensing movement and position of body parts
vestibular sense
vestibular sense detects movement in relation to gravity and the environment.
