Quick Unit 2

loss of visual abilities in a weaker eye

lack of coordination of movement in both eyes

receptor cells in muscles tell us if we are moving and in what direction

located in the semicircular canals of the ear telling body position

proximity, closure, and similarity

relies on two types: binocular and monocular

a binocular cue that is the tendency of the eyes to move toward each other as we focus on an object up close

different images of objects are cast on the retinas of each eye

cues from one eye, 2 dimensional

damage to the what pathway

form of visual agnosia in which people cannot recognize faces

visual info leaves retina, travels to superior colliculus to thalamus to primary visual cortex in the occipital lobe

colours are processed in opposite pairs and explain after images. If you stare at green too long you can’t see red

ganglion cells, thalamus and visual cortex

there are three different sensors for colour and each type responds to a different wave length

a stimulus for light

ringing in the ear

tone deafness, inability to distinguish between pitch

cochlea to brainstem to thalamus to auditory cortex to auditory associated areas in the cortex

muscle contractions, hair cells becoming less sensitive and attention (cocktail party effect)

conductive (blockage or break in hearing process) or nerve (damage or malformation of hair cells or auditory nerve)

pitch of sound

loudness
