At age 2, madeleine is given up for adoption by a mentally ill single mother who realizes she cannot provide adequate care for her daughter. shortly thereafter, madeleine is adopted by parents who provide lively conversation, lots of books and educational games, and frequent trips to zoos and museums. based on this information you might expect madeleine's iq scores to:

We don't know much about her birth mother - for example, what was the nature of her mental problems? 

But we can assume that at the beginning her IQ score would go down, influenced by the trauma of the separation from the birth mother.
