When placed in strange situations without their artificial mothers, the harlows' infant monkeys demonstrated signs of:

b)egocentrism.
c)basic trust.
d)curiosity.

A)insecure attachment.

Explanation:

There are many people or animals that are only capable of creating insecure attachment links. Put simply, this type of attachment is one in which the bond is contaminated by fear. This is expressed, mainly, as withdrawal in the relationship with others or confusing emotions, of dependence and rejection.

Most psychologists argue that insecure attachment is developed in early childhood. It would be a consequence of the relationship established by people who have this pattern of attachment with their figures or people of confidence in childhood. Those first links are the basis of those who will establish later.
