Communication Yearbook 18 originally published in 1995 focuses on cognitive approaches to the study of human communication, examining topics such as the formation of interaction goals, cognitive models of message production, mindfulness and minlessness in message processing and attention to televised messages. Sections two and three concentrate on the communicative management of health and environmental risks, critical analyses of classical approaches to risk communication and the ways in which people are connected through diverse forms of communicative behavior, including supportive relationships, electronic mail systems and ideologies. Commentaries in each section provide alternative perspectives on the state of research, extend issues of significance and help engage the reader with contemporary debates.
