| Question | Answer |
|---|---|
| detection and encoding of stimulus | sensation |
| select, organize, and interpret sensory information | perception |
| prior experience and current expectations to interpret | top-down processing |
| sensory receptors to integration of sensory information | bottom-up processing |
| able to pay attention to only one voice | cocktail party effect |
| experiment: subjects unaware of umbrella woman | inattentional blindness |
| experiment: subjects failed to notice a person was replaced | change blindness |
| exp: subject failed to notice photos were switched and supported rejected | choice blindness |
| minimum amount of stimulation needed for detection | absolute threshold |
| below conscious awareness | subliminal threshold |
| weber's law describes | difference threshold |
| stimulus (physical) energies converted into neural messages | transduction |
| personal expectations and motivation influences absolute threshold | signal detection theory |
| diminished sensitivity to an unchanging stimulus | sensory adaptation |
| two stimuli must differ by constant proportions | weber's law |
| mental predisposition that influences perceptions | perceptual set |
| light-wave amplitude= | intensity (brightness) |
| light wave frequency | Hue/color |
| sound wave frequency | pitch (high-low) |
| sound-wave amplitude | loudness (loud-quiet) |
| adjustable opening in the eye | pupil |
| regulates the amount of light entering the eye | iris |
| uses accomodation to focus images on the retina | lens |
| outside-inside of the eye | cornea, iris, pupil, lens, retina |
| where the optic nerve exits the eye | blind spot |
| more light-sensitive | rod |
| more color-sensitive | cones |
| blinking lights=perceived motion | the phi phenomenon |
| movie screen motion | stroboscopic movement |
| depth perception is natural | visual cliff |
| as we move, fixed objects appear to move | relative motion |
| perceived distance and perceived size | moon illusion |
| correct order of the ear | eardrum, hammer, anvil, stirrup, cochlea |
| damage to mechanical system | conduction hearing loss |
| rate at which impulse travels | frequency theory |
| sound frequencies stimulate the basilar membrane at specific places resulting in perceived pitch | place theory |
| damage to hair cell receptors | sensorineural hearing loss |
| the retina contains 3 different color receptors | trichromatic (young-helmholtz) theory |
| color vision depends on pairs of opposing retinal process | opponent-process theory |
| time lag between left and right auditory stimulation | sound localization |
| activation of nerve fibers in your spinal cord | gate-control theory |
| semicircular canals and body movement and position (balance) | vestibular sense |
| system for sensing the position and movement of individual body parts | kinesthesia |
| one sense influences another | sensory interaction |
