Final answer:
Verbal communication is most effectively used when conveying facts, there is time urgency, or when ideas are complicated, allowing for immediate clarification and back-and-forth discussion to ensure understanding.
Step-by-step explanation:
Verbal communication is most effective in different scenarios, depending on the context and the information being communicated. It is best used when:
Conveying facts: Verbal communication is advantageous when presenting factual information that can be clarified immediately in case of questions or misunderstandings.
There is time urgency: When immediate decision making or response is required, verbal communication provides a quick method of conveying messages.
Ideas are complicated: Complex ideas often need further explanation, which can be achieved effectively through verbal communication, allowing for immediate back-and-forth discussion to ensure understanding.
Verbal communication, therefore, should not be used when one does not require immediate feedback, as this implies the communication is not time-sensitive and other forms of communication could suffice.
