Abstract

The discovery of selective associability of cues in classical conditioning has often been treated as an embarrassment to Pavlov, because he has been represented as a proponent of the "equivalence of associability of cues." According to that doctrine, except for the influence of differences in stimulus intensity, all environmental stimuli are equally susceptible to becoming conditioned stimuli if they are arranged in a suitable time-relation to any effective unconditioned stimulus . The current paper asks whether Pavlov explicitly made such a claim and, if not, whether he could have endorsed equivalence of associability. Scientific controversy, the role that "the classics" play in scientific specialties, and the emblematic standing of the founding figures of a discipline or specialty constitute a framework for discussion of Pavlov's stand on the equivalence of associability
