Define "social cues."

Social cues refer to the nonverbal signals and indicators that provide essential context and understanding in social interactions. They encompass a wide range of expressions such as body language, facial expressions, tone of voice, and gestures, all of which can significantly influence how messages are interpreted and understood during communication.

These cues help individuals to assess the emotions, intentions, and reactions of others, and they play a crucial role in enhancing the depth and clarity of social interaction. For instance, a smile might indicate friendliness or approval, while crossed arms could signal defensiveness or discomfort. Recognizing and interpreting these signals can lead to more effective and empathetic communication, allowing individuals to engage with each other in a more meaningful way.

The other options focus on more limited aspects or specific forms of communication that do not encompass the full breadth of social cues. Verbal expressions and written instructions represent only part of communication and lack the nonverbal element that is vital in understanding context and emotions in interactions. A system of codes among friends is too narrow and specific, failing to capture the broader, more universal nature of social cues.
