Abstract

In 6 experiments, investigated the effect of stimulus-reinforcer and response-reinforcer relations on autoshaping the keypeck of a total of 94 male White Leghorn and 98 male Hubbard Golden Comet chicks. The stimulus-reinforcer relation was studied by varying the correlation between response-key illumination and heat lamp activation. The response-reinforcer relation was studied either by preventing the Ss from pecking the lighted response key during training or by comparing the performance of Ss placed on a response-dependent nonreinforcement schedule with the performance of yoked control Ss. Results reveal that respondent (stimulus-reinforcer) factors were of primary importance in the acquisition, maintenance, and discriminative stimulus control of autoshaped keypecking. Operant (response-reinforcer) factors were implicated in the maintenance of keypecking once initiated. Autoshaped keypecking is thus under the influence of both respondent and operant conditioning factors. (35 ref)
