Psych EOQ vocab 3
| Question | Answer |
|---|---|
| Accomodation | How lense takes shape to focus on objects closer or further away |
| Binocular depth cues | Depth cues that require both eyes |
| Monocular depth cues | Depth cues that require one eye |
| Conduction hearing loss | Hearing loss caused my damage to mechanical system that transmits soundwaves to cochlea. |
| depth perception | ability to see in three dimensions despite eye imagery being bidimensional |
| frequency theory | frequency of neural impulses is frequency of light/sound wave |
| gate control pain theory | spinal cord is gateway for pain, activated by small fibers from pain signals, deactivated by big fibers from brain |
| kinesthesis sensory organs are called | proprioceptors |
| what determines vestibular sense | semicircular canals and vestibular sacs in the ears |
| opponent process theory | theory of opposing color photoreceptor cells or whatever you know what this is |
| perceptual set | specific bias causing the perception stimuli one way and not another, essentially just top-down processing |
| place theory | pitch of sound is correlated with stimulated part of cochlea |
| priming | training disposition of perceptual sets, teaching your brain's top-down processing |
| sensory adaptation | diminished sensitivity in response to prolonged stimulation |
| signal detection theory | absolute thresholds depend on context |
| hypnagogic sensations | bizzare feelings as one is going to sleep (feeling of falling, feeling weightless, etc) |
| The selection, organization, and interpretation of sensory input is called | perception |
| What parts are in middle ear | Ossicles (tiny bones), ear drum, ear canal |
| What parts are in inner ear | Cochlea and eardrum |
| Where does transduction occur in the eye | Retina--specifically in rods/cones |
| Where does transduction occur in the ear | The Cochlea--specifically the stereocilia |
| Define sensation | Taking stimuli and turning it into a neural impulse |
| Define perception | Interpreting that stimuli in the brain |
| Define inattentional blindness | failure to recognize change because brain is focused on something else |
| Function of the ear flap/pinna | funnels sound waves |
| Function of ear drum | Conducts sound waves to ossicles |
| Function of ossicles | Conducts sound waves to cochlea |
| Function of cochlea | Tranduces sound wave via stereocilia |
| Function of auditory nerve | Brings action potential to thalmus |
| What are the different touch sensations | Hot, cold, pressure, pain |
| Pain is a ________________ phenomenon, meaning it relies on both ___________________ and _________________ processing | biopsychosocial, top down, bottom up |
| Touch transduction perception | nociceptors |
| True or false: pain cells are a thing | false, nociceptors are used for pretty much all of it |
| Men or women are more sensitive to pain, have better hearing and better smell by and large | women |
| Sensations of taste | sweet, sour, salty, bitter, umami, oleogustus |
| Tongue contains _________ which have _________ which have _________ which transduct the crap to yo brain | taste buds, pores, hairs |
| How does smell sorta happen | Particles in the air go up the nasal passage and slip in to the receptors in nasal cavity neurons, activating combinations of neurons that form odors when percieved |
| Smell is ____________ memorable than sight and sound | less |
| When does smell peak | Early adulthood |
| What influences sense of smell | sex, age, experience |
| What is kinesthesis | awareness of where body parts are without receiving external stimuli |
| McGurk effect | the brain finds middle ground when recieving contradicting input (ex. hearing "ga" but seeing "ba" makes a person percieve "da") |
| Synesthesia | rare condition in which the input receipt may trigger the false sensation of another input, e.g. smelling a certain order triggers a perceived burst of color |
| Volley theory | multiple bundles of neurons fire messages to transmit different frequencies; explains how we can hear pitches of sound too high for an individual neuron's firing pattern |
| Sound localization | ability to tell where a sound comes from, determined by timing and intensity with which a sound wave reaches each ear |
| Constancy | the biological relationship that different perspectives of the same object yield the same object being percieved |
| phi phenomenon | when multiple lights blink quickly in a continuous successive pattern, we perceive motion |
| stroboscopic effect | effect that multiple images rapidly presented and perceived to and by the brain yields a perceived motion |
| Information is sent to the ____ cells and then the ____ cells whose axons make up the optic nerve. | bipolar, ganglion |
| a colored object reflects | any light other than the color |
| any color can be created by combining |
