For the past five decades, research into specific features of capsule environments has been of interest to psychologists who study extreme environments. Along with this interest is a corollary theoretical effort to develop a classification system along general dimensions. The main impetus behind this endeavour appears to be a concern regarding the hypothetically harmful impact of the features. This article provides a brief overview of the environmental classification systems of Sells (1973), Harrison and Connors (1984), and Suedfeld (1987), and notes that many aspects of these approaches overlap the revised and more general transactional model of stress proposed by Folkman (2001). The utility of adopting the transactional model of stress as a guide for research into the stresses associated with living in a capsule is then discussed.
