Final answer:
People find it most difficult to detect vocal cues of extroversion when it comes to nonverbal communication.
Step-by-step explanation:
When it comes to detecting nonverbal cues, people find it most difficult to detect vocal cues of extroversion. This means that it can be challenging to accurately interpret someone's level of extroversion based on their voice. For example, someone who is introverted may put on a more extroverted voice during an interview, making it harder for the interviewer to detect their true personality.
Research has shown that interviews are influenced by both visual cues and vocal (nonverbal) cues. Visual cues of conscientiousness, openness to experience, and vocal cues of extroversion positively affect interviewer judgment. However, vocal cues of extroversion tend to be the most difficult to detect, as they can be easily modified by the candidate.
Overall, nonverbal cues, especially vocal cues, play an important role in communication, but it can be challenging to accurately interpret them in certain contexts.
