Perceptual Control Theory (PCT) was first introduced by William T. Powers in 1960 to provide an alternative account of behaviour to the dominant behavioural theories and emergent cognitive theories at the time. Derived from the principles of classical control engineering, Powers proposed that behaviour is the control of perceptual input, and specified the computational framework to operationalise the purposive behaviour of living organisms, including humans. Control is the default functioning of our brain and bodies, and it runs smoothly unless conflict occurs – defined as having opposing goal states for the same variable. According to PCT, psychopathology is characterised by loss of control that is maintained by processes that exacerbate conflict and/or prevent the exploration of conflict within conscious awareness. I will provide an overview of my own work in this field including: (a) basic lab tests of PCT; (b) modelling of individualised sensorimotor control processes; (c) modelling of goal conflict resolution; (d) plans for modelling of mental health recovery for personalised interventions – known as Dynamic Catalysts.
