| declination | | This effect may explain why the moon looks bigger on the horizon |
| current | | Resistance in a live human cell, should be 5 kohms or less for electrodiagnostics |
| biofeedback | | This visual illusion may be the basis of the corridor or hallway illusion |
| SOLI | | When accommodation plays little or no role, we judge distance from this effect |
| oscilloscope | | This part of the near triad gives us a binocular depth cue |
| bioimpedance | | Uses Gaussian principles to generate an electric field with a flowing current |
| clarity | | A high-voltage version of this can electrocute you if you open up a TV set, even if it's unplugged |
| capacitor | | Your brain can guess that the Grand Canyon is really deep by using this type of angle |
| diode | | In Los Angeles or any big city, distance can be judged by this principle because of intervening smog |
| transformer | | The variable valve of electronics, on which microchips are based |
| inductor | | Our assumption about light and shadows tells us that the usually come from this direction |
| mullerlyer | | Can be used to lower your blood pressure and diminish migraine headaches without medicine |
| electriceel | | Keeps your electrodiagnostic patients from getting a nasty shock |
| texture | | To trade current for voltage (or to turn a robot into an airplane), you need one of these |
| isolatedamplifier | | This creature has two-and-a-half times the voltage of an ERG, and over six times the wattage of the human body |
| convergence | | Software that plots voltage changes over time |
| above | | This visual illusion of lines that appear to be different lengths is probably explained by our experience with corners |
| ponzo | | Using the water works analogy, this electrical property is the equivalent to water flowing in a pipe |
| SILO | | The "check valve" of electronics |
| transistor | | How small tiles look at the far end of a long hallway is an example of judging depth by this monocular cue |
| parallax | | When we compare our own head motion with the motion of something closer to something farther away to determine distance, it is called this |
