“…The 64 theoretical papers appeared in journals related to Psychology (30), Education (5), Health (5), Business (3), Social Issues (3), Technology (3), Architecture (3) and Geography (1), as well as those classified as Multidisciplinary (7) and Other (4). Overall, most of the theoretical papers fell into five broad categories: (i) informational and/or critical papers that examined behaviour settings as a theory and/or method [43][44][45][46][47][48], often contextualizing it within a broader discussion of ecological psychology [3,[49][50][51][52][53] or environmental psychology [54,55]; (ii) papers by Barker himself [4,56], or by researchers interested in the history and development of behaviour settings theory [57]; (iii) papers concerned with the state of behaviour settings research, such as its application in the twenty-first century [58], or its apparent failure to enter mainstream psychology [59]; (iv) papers that proposed ways in which behaviour settings theory might be useful for specific areas of study, including leadership assessment [60], discipline in schools [61], education administration [62], sexual violence [63], crime more generally [64], urbanism [65], tourism [66], virtual communities [67,68] and the study of non-human species [69]; (v) papers that developed or applied mathematical models to behaviour settings theory [70][71][72].…”
