• The prefix "intra-" means "within." Therefore, intrapersonal communication is the process of communicating with oneself.
• It is the most fundamental level of communication, as it is the foundation for all other forms. It encompasses our thoughts, self-talk, and the way we process information and make sense of the world.
• The effectiveness of our intrapersonal communication depends on four key qualities of the communicator:
  • Frame of Reference: Our unique background and experiences that shape our perceptions.
  • Creativity: Our ability to generate new ideas and perspectives.
  • Self-Talk: The silent or spoken conversations we have with ourselves, which influence our confidence and actions.
  • Risk-Taking Behavior: Our willingness to venture into new areas of thought and challenge our own assumptions.

• The prefix "inter-" means "between" or "among." Interpersonal communication is the exchange that occurs between two or more people.
• This can range from a one-on-one conversation or dialogue to a small group discussion. There are two primary ways to view this level:
• Contextual View: This defines interpersonal communication simply by its context—any communication that occurs between two people.
• Developmental View: This defines it by the quality of the interaction. In this view, communication becomes truly interpersonal only when the individuals have known each other for some time and interact based on their unique personalities, rather than just fulfilling social roles.

This level of communication involves a single speaker (or a small, unified group) delivering a message to an audience. The feedback in public communication is often delayed or limited compared to interpersonal exchanges. Examples include lectures, presentations, and public speeches.

Mass communication involves sending a message to a large, public, dissimilar, anonymous, and distant audience through an intermediate instrument of transfer. The feedback is typically indirect and slow. Common channels for mass communication include television, radio, and newspapers.

Mediated communication occurs whenever an intermediate medium or device is used to carry a message between communicators. This form is distinct from face-to-face interaction.

• The telephone is a classic example of a device used for mediated communication.
• In a business context, written forms like letters, reports, forms, and interoffice memoranda are also key examples of mediated communication.
• While mass communication is always mediated, not all mediated communication is mass communication (e.g., a phone call between two friends is mediated but not mass).
