Answer:
Kinesics
Explanation:
<u>The theory of Kinesics was developed by Ray L. Birdwhistell.</u> According to this theory, kinesics is the study of body movements. In other words, it can be defined as an interpretation of non-verbal behavioral movements.
Birdwhistell claimed that all body movements or postures are not accidental, hence, they have the meaning of their own.
<u>In the given case, wrinkling of the nose, according to the theory, is an example of kinesics, because wrinkling of the nose conveys the meaning that the food smelled bad</u>.
