psych1101 exam 3

selective attention

narrowing down to attending to certain things that are more important in a scenario

filter theory of attention

all possible inputs that sensory COULD respond to, sensory buffer: sensory systems , sensory organs, ALSO NO CONTROL, FILTERS: DOOO have control over, attentional resources sensory organs responding to it, making it into longer term memory if so desired

cocktail effect

talking to someone at a party, but attention is drawn elsewhere when your name is heard

inattentional blindness

 reduced ability to notice changes if we are attending to something else

change blindness

given complex scenes, we can only attend to a limited number of things

attentional blink

brief period after attending to a specific stimuli during which we may miss new info

distributive represntation

representation that is spread throughout different parts of the brain 

fovea

visual system- recieving light- This is the spot where your eye focuses light, and is the most densely packed part of the eye with color and high definition cones cells

trichromatic theory

trichromatic cone cells respond positively to one of the three frequencies exhibited by photos arriving on their surface (3 CONE TYPES RED GREEN AND BLUE)

outer ear- funneled connected sound

• Pinna: visible outer ear

• Auditory canal: where sound travels to eardrum

• eardrum/ tympanic membrane

middle ear - amplifying sound waves

• Ossicles- bony structures hinging on one another to amplify soundwaves as they move into ear (3 tiny bones: hammer, anvil, stirrup)   

• Incus, malleus, stapes

Malleus- HAMMER Incus- ANVIL Stapes- STIRRUP

inner ear- “retina” of the auditory system

• Cochlea- generate APs, transduced/transformed into action potentials otherwise brain cannot understand

- Damage to cochlea can lead to hearing loss
