Which of the following principles influencing perceptual selection is being used in an attempt to catch the attention of viewers when a television commercial is presented in a higher volume (i.e. ,louder) than the volume of the ongoing program?

A) intensity
B) learning
C) repetition
D) continuity

The principle of intensity is being used in this scenario as the higher volume of the commercial is meant to catch the attention of the viewers by standing out from the ongoing program. This principle suggests that stimuli that are intense or high in magnitude are more likely to be noticed and perceived by individuals.
