Expressive communication refers to encoding of a message to the decoder to make something happen or to stop something in progress. Expressive language includes making requests, giving information or command, and so on; hence, it cannot be passive. Individuals with language disorders and those who lack expressive language skills suffer frustration of not being able to get across and it reflects in behaviour which may be one of passive aggression. This phenomenon is observed in toddlers, too. They get irritable and throw tantrums when they are unable to express what they want, or how they feel. What one expresses flows from one’s mind; so, external clues do not drive it. Expressive communication does not depend on the equation between the encoder and the decoder.
