Last year I presented a paper about ideomotor action. This year's paper continues and develops the ideas. There is now research evidence (using PET and MRI scanning) which demonstrates that bodily action is preceded by a mental picturing of the proposed action (something Pribram called an Image of Achievement). That is, a perceptually-organised pattern is transduced into a motor program and executed by the changes in posture, changes in limb positions which constitute human action. This gives a neurological realisation of what in evolutionary terms must have been an intimate intertwining of perception and action not as separate functions but as part of single system for effective behaviour in any creature's environment. What this paper goes on to consider is whether if action follows on from brain image, does the converse apply? does externally perceived action produce an internalised motor program which is available in its turn to be imaged and then expressed by action of the perceiving individual? If so, this throws light on something of very great importance but which has remained poorly understood until now, the nature of imitation. It also has many other applications or implications, for example, the impact of TV, video or film scenes of action, the behaviour of crowds or mobs, or more generally conformist behaviour, the operation of language in hypnosis or oratory. There are of course detailed questions open to research: the nature of the transition between visual image and motor program, the relation between language and action, the location in the brain of the processes linking vision and motor programs, the scope for simulating such processes in artificial intelligence, the implications for evolutionary psychology, the contact with thought about representation.
