Shelby created an animated scene using her computer. She drew a frog as he started to jump, and then drew the frog landing. The computer created 24 pictures between these two points, which adjusted the frog's position very slightly. When the entire sequence of 26 pictures is displayed in rapid succession, the frog appears to hop smoothly. This perception of smooth action is one example of
A) preattentive processing.
B) the phi phenomenon.
C) bottom-up processing.
D) feature detection.

Question

Quizplus · Accepted Answer

The phi phenomenon refers to the illusion of movement that occurs when two or more adjacent stationary stimuli are presented rapidly in succession. In this case, the successive images of the frog hopping create the illusion of smooth movement, which is an example of the phi phenomenon. The other options are not applicable to this scenario.
