 As a condition of the adoption, the parents agreed to in-person visits of up to four times a year by the study's research team, where the children would be observed, questioned, tested and/or filmed, without knowing the true nature of the study.The parents of the adopted children were also not informed by Louise Wise Services that they were part of a twin or triplet set, and one biological mother to a set of twins separated by Bernard and studied by Neubauer reported that Louise Wise Services did not inform her that her children would be separated.Ultimately, one of separated siblings committed suicide.
