Functional Communication Training: What the Evidence Says About Replacing Behaviour with Communication
Functional Communication Training (FCT) starts from a functional assessment of a challenging behaviour, then teaches a communication response — a phrase, sign, card, or device press — that earns the same outcome. First demonstrated by Carr and Durand in 1985, it has become one of the most researched function-based interventions in behaviour analysis, with consistently large reductions in challenging behaviour across large clinical case series. The evidence is strongest when the communication response is honoured every time at first and reinforcement is then thinned deliberately; most treatment failures trace to skipping one of those two steps.
The Good Behaviour Game: An Evidence-Based Classroom Management Framework
The Good Behaviour Game is an interdependent group contingency: teams of students earn rewards by keeping rule violations below a set limit, or by demonstrating expected behaviours. A robust evidence base, including meta-analyses of single-case research, shows it is a highly effective way to reduce disruptive behaviour and increase academic engagement across diverse settings.
