A. Roger Chillingworth
Melancholy
Explanation:
The character that expresses these feelings is the character of Roger Chillingworth. Chillingworth states this when he arrives to the town and heard about the fate that has befallen Hester. He states that it is a good thing that she was punished with the scarlet letter. However, he also laments the fact that the man who is responsible for her child has not come forward.
This is how Mr. Dimmesdale's eyes are described. He is said to have melancholy eyes, which means very sad eyes. He is also described as young, pale, frail and phisically weak. He is delicate and has a tremulous mouth.
"Pavlov's dog" experiments with bell ringing as the association, operating on food being served after the bell's chime, involved him measuring the dogs' salivation quantity as a result. It was a study on classical conditioning.
He showed that two things become associated because there is anticipation of reward.
