Answer:
Once the contingency was restored, the sad babies turned away .
Explanation:
Babies associated the rope with the moment of happiness, as the string provided feelings of happiness and pleasure for them. As scientists withdrew these elements of happiness, babies could no longer have those sounds and images that made them happy, so the association between the string and happiness came out of their heads more and more until the moment came. they completely disassociated the rope of happiness and began to grow sad and turned away.
As a result, scientists concluded that since pulling the rope no longer turned on the attractive stimuli, and the emotional reactions of babies, they changed the feeling of happiness to anger and sadness. Once the contingency was restored, the sad babies turned away.
