Diseases
Cataracts
clouding of the natural lense of the eye
2 senses in the ear
Hearing and Balance
Retinal disparity
each eye sees the same object only a little bit differntly
How does the vestibular system work?
positioning of the head to help us maintain balance
2 chemical senses
smell and taste
Glaucoma
damage to the ocular nerve
frequency in relation to ear
number of vibrations in the sound wave
Trichromatic Theory
three types of receptors in the eyes that see the different colors
Motion parallax
helps our eyes perceive the distance of an object
Proximity
the way our brains group things based on how close together they are
Macular degeneration
progressive eye degeneration (effects Macula)
Amplitude in relation to the ear
(Loudness) Size or intensity of the sound wave
Which senses do we know the most about?
sight and hearing
Somesthesis
where we are in space, uses all of our senses
What are “cones and rods” in the eye?
responsible for converting light in to electrical signals that enter the eye
Congenital analgesia
mutations in the gene that affect the transmission of pain signals
Temporal coding (Auditory)
neurons firing in response to sound stimuli
Kinesthesis
The movement of our body in space
Perceptual set
the way we perceive things based on past experiences
Who is better at detecting odors-men or women?
Women becuase of the olfactory bulb size and estrogen hormone
Synesthesia
Selective attention
Our brains only focus on one stimulus allowing us to tune out distractions
How does the Stroop effect work?
Figure-ground perception
how we see the object against the background in
Thermal Nociceptors (pain receptors to alert when temperatures cause tissue damage)
Mechanical Nociceptors (respond to physical injury)
