Task: Class Definition Understanding (ontology: Human_Society/EmotionOntology)

Which of the following definitions best describes 'nonassociative learning'?

A. A decrease in a behavioral response to a repeated stimulus. This is exemplified by the failure of a person to show a startle response to a loud noise that has been repeatedly presented.
B. A simple form of learning whereby the repeated presence of a stimulus leads to a change in the probability or strength of the response to that stimulus. There is no association of one type of stimulus with another, rather it is a generalized response to the environment.
C. Learning to anticipate future events on the basis of past experience with the consequences of one's own behavior.
D. The temporary recovery of response to a stimulus when a novel stimulus is added.

Answer: A simple form of learning whereby the repeated presence of a stimulus leads to a change in the probability or strength of the response to that stimulus. There is no association of one type of stimulus with another, rather it is a generalized response to the environment.
