The forms of direct, deliberate communication in place of spoken language from the options provided are:
-
Sign language: This is a structured language that uses hand signs, facial expressions, and body movements to convey meaning.
-
Signal lights: These are often used for communication, particularly in specific contexts like traffic signals or signaling systems.
While smiling, frowning, and posture can convey meaning and emotion, they are typically more associated with non-verbal cues rather than forms of direct communication like sign language. Hairstyle is generally a personal choice and does not typically serve as a direct form of communication.
