Psychology Terms - Aliasing
A distortion in a visual or auditory signal, or any periodic or oscillating variable or time series, occurs when the variable is sampled at an inadequately low frequency relative to the signal's frequency. A well-known cinematographic example is the *wagon wheel illusion, where the wheels of a stagecoach seem to rotate slowly in one direction and then the opposite as it accelerates. A 1,000 hertz sine wave would seem motionless if sampled precisely once per millisecond or once every two milliseconds, and it would appear to cycle very slowly if recorded at a frequency near once per millisecond.
