| Sensation is . . . | The stimulation of sensory receptors and transmission of sensory information to the central nervous system |
| Perception is . . . | The psychological process through which we interpret sensory stimulation, reflecting our learning, expectations and attitude |
| Absolute threshold | The weakest amount of a stimulus that can be sensed |
| Difference threshold | The minimum amount of difference that can be detected between two stimuli |
| Sensory adaptation | The process by which we become more sensitive to weak stimuli and less sensitive to unchanging stimuli |
| Blind spot | Where the optic nerve leaves the eye to transmit visual information to the brain and there are no photoreceptors |
| Dark and light adaptation | Our eyes adapt to the light much more quickly than they adapt to the dark |
| Complementary colors | The colors across from each other in a color circle, which when mixed together give you grey |
| Afterimage | The complementary color of a color; after you look at a color and it is removed, you perceive the afterimage |
| Closure | The tendency to perceive a complete or whole figure even when there are gaps in what your senses tell you |
| Figure-ground perception | When there is a figure against a background, what we perceive as the figure and what we perceive as the background influence our perception |
| Similarity | We perceive similar objects as belonging together |
| Continuity | People prefer to see continuous patterns like lines and waves, not disrupted ones |
| Depth perception | Perceiving the depth of objects |
| Monocular cues | Depth perception cues that need only one eye to be perceived |
| Binocular cues | Depth perception cues that need two eyes to be perceived |
| Perspective | A monocular cue: faraway objects look smaller than they really are |
| Overlapping | A monocular cues: if an object is overlapped, we perceive it as more distant |
| Texture gradient | A monocular cue: closer objects are perceived as having a more varied texture |
| Parallax | A monocular cue: when we are moving, more distant objects appear to be moving with us |
