Overview of Communication

Definition and Nature of Communication

 Communication is defined as behavior that sends a message to others, which can
include human gestures, animal sounds, and even chemical signals from insects.

 It is important to distinguish communication from language; while language is a
structured system of symbols, communication encompasses a broader range of signaling
behaviors.

 Examples of communication include a human sighing in irritation, a dog barking to alert
its owner, or pheromones released by insects to signal danger.

 Aposematism is a form of communication where conspicuous signals warn potential
predators of toxicity or danger, highlighting the importance of visibility in
communication.

 The effectiveness of communication relies on the receiver's perceptual system to
process the signals, which can vary significantly across species.

, Signals, Senders, and Receivers

 Communication involves a sender who transmits a signal and a receiver who interprets
it; this interaction is crucial for effective communication.
