Question

Which of the following statements is false?

a. Speakers rated as sincere make eye contact three or more times often than insincere speakers
b. For 90% of Americans, the left eye is used only for depth perception
c. When Richard Nixon attended his first Watergate press conference, he blinked up to 40 times a minute
d. Sincere speakers blink between 5 and 10 times per minute

Answer 1

The false statement is b. For 90% of Americans, the left eye is used only for depth perception, which is incorrect as both eyes contribute to depth perception.

Step-by-step explanation:

The question presented falls under the category of Social Studies and deals with the subject of nonverbal communication's role in public perception, particularly in the contexts of political debates and public speaking. An example of this can be seen in the historical presidential debates and the impact of visual presentation on audiences' perceptions of sincerity and reliability.

To address the false statement in the question:

• Statement a. is not necessarily false as making eye contact can be associated with sincerity.
• Statement b. is false; the left eye is not used exclusively for depth perception; both eyes are used to perceive depth, and lateral dominance in vision is not as clear-cut.
• Statement c. about Richard Nixon could be true, as increased blinking can be associated with stress, which Nixon may have experienced during the Watergate scandal.
• Statement d. is not false since sincere speakers can blink more or less than this range in various contexts, and the average human blinks 15 to 20 times a minute according to biological norms.
