Which of the following behaviors is NOT typically seen as an emblem?

An emblem is a nonverbal gesture that has a specific, well-understood meaning within a particular culture or context, often substituting for words.

Nodding one's head is commonly recognized as a sign of agreement or understanding across many cultures. Pointing at something typically directs attention and conveys a specific message without the need for words. Showing a thumbs up is widely understood as a symbol of approval or positive affirmation.

Rubbing one's hands together, however, is not typically categorized as an emblem. While it can convey anticipation, nervousness, or excitement, it does not have a universally recognized meaning that substitutes for a verbal expression in the same way as the other examples. Thus, rubbing one's hands together lacks the clear, defined communicative intent associated with standard emblems, making it the behavior that is NOT typically seen as an emblem.
