communication
n. the transmission of information, which may be by verbal (oral or written) or nonverbal means (see nonverbal communication). Humans communicate to relate and exchange ideas, knowledge, feelings, and experiences and for many other interpersonal and social purposes. Nonhuman animals likewise communicate vocally or nonvocally for a variety of purposes (see animal communication). Communication is studied by cognitive and experimental psychologists, and communication disorders are treated by mental and behavioral health therapists and by speech and language therapists. Communications is the discipline that studies the processes and systems involved in communication at both the interpersonal and broadly social levels, in the latter case paying particular attention to the publishing media and telecommunication systems (telephones, radio, television, Internet, etc.).
