Pavlov effect is a classical conditioned reflex, that is, one stimulus is connected with another unconditional stimulus with reward or punishment for many times, which enables individuals to learn to trigger a conditioned response similar to unconditional response when presenting a stimulus alone. The principle is as follows:

1. At the beginning of the experiment, the bell is presented first, and the dog does not secrete saliva. At this time, the bell is just a neutral stimulus.

2. After that, let the bell appear a few seconds before the food. In this way, after pairing the bell with food for many times, the dog will also secrete saliva when only the bell is given without food.

3. The neutral stimulus bell becomes the signal of food because it is paired with food many times, that is, conditioned stimulus, which makes dogs secrete saliva as a conditioned response. Pavlov called the establishment of the connection between the clock and saliva secretion a conditioned reflex.

Theoretical achievements of Pavlov effect

1. Pavlov's theory adheres to the dialectical unity of subjective and objective phenomena, emphasizes that all subjective activities are causal determinism caused by external influences, and advocates using conditioned reflex as an objective experimental method to study psychological phenomena scientifically.

2. Therefore, Pavlov's theory insists on the dialectical unity of psychological phenomena and physiological phenomena, and advocates finding out the physiological mechanism of psychological activities from the law of central nervous system activities.

3. In addition, we should adhere to the dialectical unity of the body and the environment, and regard conditioned reflex as an element of the interaction between the body and the outside world. It is constantly established and changed in the process of maintaining balance between the body and the outside world, and it obeys the law of the movement and development of things.
