ABSTRACT
There is a considerable current debate about behaviourism and its various offshoots, particularly ABA (Applied Behavioural Analysis) and PBS (Positive Behaviour Support). Both models are used extensively in the United States when working with children, young people and adults with autism and/or learning difficulties, but much less so in the UK. There are continued efforts from exponents of behaviourism to get it much more widely used (Fisher, Piazza and Roane, 2011; LaVigna and Willis, 2012; Gore et al., 2013; Foran et al., 2015, for example).
