Pavlov, Ivan (1849-1936) A Russian physiologist and psychologist, Pavlov began investigating the digestive system, which led to experiments with the effects of behavior on the nervous system and the body s automatic functions. He used animals in researching conditioned reflex actions to a variety... 

Seventy years later, in 1894, a student of Pavlov, Ivan Leukich Dolinsky, rediscovered this effect and noted that acid in the duodenum of the dog stimulated pancreatic secretion. It was on the basis of the earlier French observations that William Bayliss and his brother-in-law, Ernest Starling, on the afternoon of January 16, 1901, tested Dolinsky s thesis and proved the existence of chemical messengers (hormones) that regulated secretion.

Classical or Pavlovian conditioning was first demonstrated by Ivan Pavlov in 1927. When food was presented to a hungry dog, it salivated. The food in this case was called the unconditioned stimulus, and salivating was the unconditioned response. Salivation is a natural, automatic response to the sight and smell of food, a reaction to make the chewing and digestion of the food easier.

Rapid progress in gastroenterological research was initiated by the discovery by William Front (Guy s and St. Thomas hospitals London), in 1823, of the presence of inorganic, hydrochloric acid in the stomach and by Ivan P. Pavlov (Saint-Petersburg) in 1890, of neuro-reflex stimulation of secretion of this acid that was awarded Nobel Prize in 1904. Then, James W. Black (Figure 1.34), at that time pharmacologist at Smith Kline and French, who followed L. Popielski s concept of histamine involvement in the stimulation of this secretion, was awarded second Nobel... 

Pavhvian conditioning explains behavior as reflexive in nature. The traditional example is of dogs salivating when a stimulus, a bell, is paired with the presentation of food. After repeated pairings, Ivan Pavlov found the conditioned or learned stimulus produces the same response as the unconditioned or natural stimulus. An example of this type of motivation is the fear and anxiety people feel when they enter a location where they have been injured. The location becomes a conditioned stimulus or cue producing the natural emotional response. 

Some 70 years later, the fact that acid in the duodenum stimulates pancreatic secretion was rediscovered in Pavlov s St. Petersburg laboratory by his student, Ivan Leukich Dolinsky. 

This is an experimental, surgical technique introduced by the famous Russian physiologist-psychologist, Ivan Petrovich Pavlov. A portion of the stomach is brought to the body wall and formed into a pouch from which samples may be taken. Secretions in the pouch are the same as those in the stomach. 

Classical conditioning was discovered by Russian physiologist Ivan Pavlov, who found that dogs could be trained to salivate at the sound of a bell rung a few seconds before the dogs were fed. The reaction (salivation), he found, could be transferred to another stimulus (the sound of the bell) that would not normally produce this reaction.

The next layer in material selection based on feel involves the concept of response. Like all animals, humans respond to sensory input. The response may be an involuntary action (like your knee kicking out), a body sensation (feeling dizzy), a physical action (salivating when you smell food), an emotional response (feeling happy when you hug your child), or a combination of these items. It may also involve an intellectual assessment, where one evaluates the sensory input and makes a conscious decision on what actions to take next (such as whether or not they should yell Turn that music down ). These responses may also be affected by conditioning (either intentional or unintentional). The Russian physiologist Ivan Pavlov... 

Figure 7.6 Ivan Pavlov. Does that name ring a bell ...

Ivan Pavlov, Wikipedia The Free Encyclopedia. http //en.wikipedia. org/wiki/Ivan Pavlov, actually it was not the ringing of a bell, but other stimuli.
