Final answer:
Undecided voters are more likely to retain visual images compared to sound bites, as visual encoding creates stronger memories through easily recalled images.
Step-by-step explanation:
The question asks what undecided voters will retain better compared to academic sound bites. Based on the provided background information, undecided voters are more likely to retain visual images rather than sound bites. This is because visual encoding helps in creating stronger memories due to the ability to recall images easily compared to words alone.
The discussion around coverage and effectiveness of different forms of communication during elections, such as televised sound bites and visual images, ties into the concepts of political communication and voter behavior in the Social Studies curriculum.
