Extreme environments are so named due to the unique challenges they pose to human performance. In this online subject you will learn about the factors that characterise an environment as extreme, and how living and/or working in an extreme environment can influence human functioning. In this context, you will consider how individuals and groups can manage distress and enhance resilience. Extreme environments considered include Antarctica, outer space, military operations, disaster sites, and cults. In this subject, you will examine how intrapersonal, interpersonal, and organisational factors influence the challenges posed by extreme environments. This subject would be of benefit to students with an interest in factors which influence human performance and resilience, and to students who work in, or intend to work in, extreme environments.
