| Abstract: | Four experiments explored the formation of associations among elements of a compound visual CS in an autoshaping preparation using pigeon subjects. Experiment 1 found evidence for such associations when the compound was presented without food reinforcement. Experiments 2 and 3 demonstrated that compounds embedded in procedures that produce blocking and conditioned inhibition also developed associations among their elements. Experiment 4 found, using a conditional discrimination procedure, that such within-signal associations were weakened, but not eliminated, by the presentation of food reinforcement at the end of the compound. These results suggest a pervasive role for within-signal associations across a variety of conditioning procedures that have been given central roles in current theories of conditioning. |
