| convergence | If an object is closer, your eyes must turn inward in order to focus on it. |
| retinal disparity | the fact that the left and right fields of vision provide slightly different visual images when focusing on a single object. |
| top-down processing | Basically, it's when you interpret what your senses detect. You use your memories, history, and emotion to interpret different events. |
| bottom-up processing | has to do with your five senses; we detect the lines, angles, and colors that form a flower; What am I looking at? |
| (sensory) transduction | translation of incoming stimuli into neural signals; |
| absolute threshold | the lowest level of stimulus needed to detect a smell, a sound, or a ray of light. |
| difference threshold | This is the minimum difference between two stimuli required for detection 50% of the time. |
| subliminal messages | also called a hidden message, is one that’s designed to pass below absolute threshold. |
| signal detection | we notice things based on how strong they are and on how much we're paying attention |
| sensory adaptation | When a stimulus is unchanging, you eventually become less sensitive to it. This is INVOLUNTARY. |
| sensory habituation | a behavioral phenomenon involving a decreased response to something that occurs over time. VOLUNTARY. |
