| Transportation of stimuli to the central nervous system | Transduction |
| Process of attending to organizing and interpreting info. that has been sensed. It is inferential. | Perception |
| Smallest amount of physical energy that can be reliably detected. | Absolute Threshold |
| Smallest difference between two stimuli that you can reliably detect. | Difference Threshold |
| Below absolute threshold. | Subliminal Threshold |
| Ability to detect some stimulus. Affected by intensity of stimulus and psychological/physical state. | Signal Detection Theory |
| Reduction of activity/sensitivity in sensory receptors with repeated constant exposure. | Sensory Adaptation |
| Focusing our conscious awareness of a particular event or stimulus. | Selective Attention |
| Failure to see visible objects when our attention is focused elsewhere. | Inattentional Blindness |
| Form of inattention blindness. Failure to detect changes in your visual environment. | Change Blindness |
| Active at higher light levels. Color vision and high spatial activity. | Cones |
| Vision at low light levels. Do not mediate color vision and have low spatial activity. | Rods |
| Visual ability to perceive the world in three dimensions couple with the ability to gauge how far away an object is. Monocular=one, allow to perceive depth. | Depth Perception |
| Perceiving objects as unchanging even as illumination and retinal image change. Shape and size. | Perceptual Constancy |
| "whole". Figure/ground, similarity, proximity, closure, continuity and order/symmetry. | Gestalt Principles |
| Objects that tend to travel toward us grow in size and the ones that move away shrink in size. Same is true if the observer moves away or closer to object. | Motion Perception |
| Study of hues as a determinant of human behavior. Color influences perception that are not obvious. | Color Perception. |
| Mental predispositions to perceive one thing and not the other. | Perceptual Set |
