Final answer:
Lisa is upset with Scott's use of paralanguage, which includes non-verbal elements like tone and pitch that modify meaning and convey emotion during communication.
Step-by-step explanation:
During the argument when Lisa tells her husband Scott, "It's not what you said, it's how you said it," Lisa is upset with Scott's use of paralanguage. Paralanguage refers to the non-verbal elements of communication used to modify meaning and convey emotion, which can include the tone, pitch, and volume of voice. It also encompasses the pace and interruptions in speech. Lisa's concern with the tone and manner in which Scott spoke indicates that she is sensitive to the paralanguage components of their communication.
Paralanguage includes considerations such as tone, language, and accent, which can heavily impact how a message is received. It involves non-verbal cues like pitch, volume, and speed of speech, as well as vocal qualities like sighs, laughter, or vocal fillers. In this case, Lisa is unhappy with the way Scott communicated, rather than the actual content of his message.
