"Stephen Willats'' major essay ''The Artist as an Instigator of Changes in Social Cognition and Behaviour'' is re-issued for the first time by Occasional Papers. Published in 1973 by Gallery House, London – where Willats was Director of the Centre for Behavioural Art – and long out of print, the paper includes rigorous analyses of social forms of artistic production and descriptions of a number of projects by the artist. The new OP [Occasional Press] edition features the original text, accompanied by archival images and a specially written introduction by Willats." -- publisher''s statement.
