In the communication model, which element did Harriet overlook when students laughed during her speech?

The correct answer is feedback. In the communication model, feedback refers to the responses that the audience provides to the speaker during or after a speech. When students laughed during Harriet's presentation, that reaction served as a form of feedback indicating their engagement or reaction to specific points she made.

Harriet may have overlooked this important element by not recognizing that laughter is a cue from the audience about their understanding, enjoyment, or acceptance of her content. Effective speakers should be attuned to such feedback and adjust their delivery or content accordingly in real time to enhance communication. Understanding and utilizing feedback allows speakers to create a more interactive and responsive experience during their presentations.
