During the child's first visit, the dentist requested that the parents wait in the reception room. the child cried moderately, but tearfully, throughout the dental examination and prophylaxis. the dentist "gave her permission" to cry while he/she worked and then took no notice of her crying. her crying diminished in intensity over time and then stopped. with respect only to the crying behavior, the dentist has)a. used positive reinforcement. b. used negative reinforcement. c. extinguished the behavior. d. ignored the problem.

C.extinguished the behaviour

Explanation:

Extinguished the behaviour:

What would help a person stop getting involved in a former conditioned behaviour?

Psychologist used the extinction method in which the conditioned response is slowly decreased until that conditioned behaviour is completely eliminated.

For example above the child is allowed to cry without parents or dentist's intervention and as no one intervened the child ended up stopping alone with no help so they have allowed the behaviour to get extinct .

they encountered severe weather for which they were poorly prepared.
