Final answer:
The facial expression commonly associated with emotions pertaining to questions such as WHERE, WHO, WHEN, WHAT, and WHY is raised eyebrows. This is consistent with innate universal expressions of emotion related to surprise and inquiry.
Step-by-step explanation:
The facial expression most commonly associated with the emotions represented by interrogative words like WHERE, WHO, WHEN, WHAT, and WHY is raised eyebrows. This is because such facial expressions reflect a state of uncertainty or inquiry, communicating a need for information. According to research on universal facial expressions by Paul Ekman and others, the ability to recognize and produce facial expressions of emotion seems to be innate and not learned through visual cues, as is evident from studies on individuals who are congenitally blind. Despite this universality, cultural differences can influence the display of these expressions.
While not explicitly covered in the reference materials provided, raised eyebrows are associated with emotions like surprise and confusion, which are closely linked to asking questions. Moreover, the facial feedback hypothesis suggests that our facial expressions can impact our emotional experience, hence making a specific expression could in a way reinforce the emotion behind an interrogative state.
