Typically, there should only be a brief interval between presentation of the conditioned stimulus and the unconditioned stimulus. Top managements reaction to unfavorable differences is not influenced by the materiality of the difference. Figure 6.3 Ivan Pavlov's research on the digestive system of dogs unexpectedly led to his discovery of the learning process now known as classical conditioning. Explain why there is this discrepancy.

(1992) Hierarchical associative relations in Pavlovian conditioning and instrumental training. The conditioned stimulus uses a signal to announce the unconditioned stimulus, meaning that the two stimuli are dependent on each other for associative learning. Posted on February 22, 2022 by .
