“…A general trend can be recognised in the literature to utilise approaches that attempt to avoid eliciting frustration-related aggression and avoid the use of extinction procedures that elicit frustration. These approaches have been variously described as relational therapy (Giles & Manchester, 2006), non-aversive (Giles, Wager, Fong, & Waraich, 2005; Giles et al, 2009; Manchester, Hodgkinson, Pfaff, & Nguyen, 1997; Rothwell, LaVigna, & Willis, 1999), errorless rehabilitation (Ducharme & Harris, 2005), intensive positive behavioural supports (Gardner, Bird, Maguire, Carreiro, & Abenaim, 2003), and low arousal (McDonnell, 2010). Slifer and co-workers (1997) reported the successful use of the titration of environmental and interpersonal stimulation to reduce aggression in the acute rehabilitation of children and adolescents with TBI.…”
