Final answer:
The example of 'attentional saturation' given in the selection refers to participants in a study being unable to recall details of images they see every day due to constant exposure to the same brand message across multiple platforms.
Step-by-step explanation:
The concept of attentional saturation is exemplified in the selection by the Miller beer advertising campaign. In the provided text, we see that attentional saturation occurs as a consumer is bombarded with the same brand message through multiple mediums — billboards on the way to a stadium, commercials on the stadium's big screen, and advertisements during halftime, all showcasing Miller beer. This relentless exposure creates a situation where the brand becomes easily recallable and dominates the consumer's attention, leading to what is known as attentional saturation. Hence, the answer to the question regarding the example of attentional saturation the author provides in the selection is: Participants in a study could not recall details of images seen every day.
