Scientific programmes in Antarctica have depended for their fulfilment on small groups of men working in conditions of prolonged social isolation in an alien physical environment. This is true of both early and recent phases of exploration: despite massive advances in technology and, hence, in material comforts and communications over the period, the element of prolonged social isolation remains as a dominant psychological problem. Contrary to the popular image of lonely living conditions and heroic tasks, the Antarctic worker has to cope with the very opposite of loneliness, and his tasks are likely to be mundane and routine. In his work he must adapt to a close, and closed, interpersonal world, and it is with this adaptation that the present article is concerned.
