Abstract
Conditioning of a voluntary response was studied by arranging a tone and a light as CS and UCS respectively with a CS-UCS interval of 200 msec. Ss in Group C were instructed to respond to the light by pressing a key (1250 gm of force, 6250 gm cm of work). Ss in Group E pressed to a prescribed extent to the CS (contextual activity of 500 gm of force or 1000 gm cm of work) and completed the reaction in response to the UCS. It was found that far more CRs and more uniform results were obtained in Group E, suggesting that, with the control of a certain contextual variable, results without exceptions may not be out of our reach.
