The fast movement of briefly flashed images in an animated motion picture produces what effect? subliminal messaging convergence autokinetic effect stroboscopic movement phi phenomenon

The answer is Stroboscopic movement

Explanation:

Stroboscopic movement occurs when we do not see a motion continuously but in discrete shots. It is an effect in which we see an object at one place and after another instant the object seems to have shifted it's position.

Auto kinetic effect is an effect in which a stationary point of light appears to move.It occurs as our brains can perceive motion relative to some other object and cannot observe ,motion along a featureless terrain or environment.

Phi effect causes an observer to perceive motion in stationary objects.
