‘Changing the Pattern of Behaviour – Outline of a Therapy for Criminal Reform’ by Kenneth J. Maconochie argues that the Mark system and the Alexander Technique ‘in combination, approach nearer than any single system known to being a therapy of criminal reform’. 
Kenneth Maconochie was the great-grandson of Captain Alexander Maconochie (1787–1860), pioneer in Penology, who was the inventor of the Mark System of penal discipline in 1840. The system, of rewarding good behaviour, with more opportunities and freedom within a prison, is now adopted in various forms around the world. In the article ‘Changing the Pattern of Behaviour’ Maconochie argues that the Alexander Technique has much to offer a penal system in conjunction with the Mark System, especially in terms of making people more conscious of their choices and of the consequences of those choices.
