| sensation | any physical energy captured by the senses |
| perception | the brain's organization & interpretation of physical information |
| transduction | the process of turning physical information (ex: light waves) into chemical-electrical messages to the brain |
| adaptation | the process by which senses gradually adjust to constant levels of stimuli |
| just noticeable difference | the least amount of change we can detect in a stimulus |
| absolute threshold | the smallest amount of a stimulus we can detect 50% of the time |
| subliminal stimulus | a stimulus below your absolute threshold (undetectable) |
| change | the most important factor our senses detect |
| blind spot | the place on each retina where the optic nerve attaches so there are no rods or cones |
| convergence | the process of merging images from two eyes into one 3D image |
| retinal disparity | the difference in images received by two different eyeballs |
| continuity | the tendency to organize stimuli into smooth, continuous patterns |
| proximity | the tendency to group together items located closer together |
| similarity | the tendency to group together items that are alike |
| closure | the tendency to "fill in" any missing parts so it all makes sense |
| shape constancy | the tendency to perceive objects as retaining original shape even when shape on retina changes because we look from a different angle |
| size constancy | the tendency to perceive objects as retaining consistent size even when size on retina changes because the object moves closer or further away |
| interposition | the process of using overlap as an indication of depth |
| figure-ground | the tendency to distinguish between a detailed focus object and a background when we organize & interpret sensations |
| motion parallax | the process of using relative speed as an indication of depth |
