Development to the Institute of Child Development. It is also carried out
cooperatively by the faculty, staff, and students of the Institute of Child
Development, whose efforts should be recognized here. Special
acknowledgment is given to the Minnesota Symposium committee,
composed of the following: Douglas Bolin, Judith Brady, Joyce Brady, Mary
Anne Chalkley, Helen Dickison, Wayne Duncan, Virginia Eaton, Wendy
Gibson, Elizabeth Haugen, Judith List, Frank Manis, and Richard
Omanson. In addition, Ulrike Richardson was an efficient and enterprising
assistant and secretary throughout the symposium and the preparation of this
volume.

The pleasure of editing a volume such as this comes largely in the
opportunity to work with talented contributors like the authors of the
chapters that follow. I appreciate both their intellectual and their personal
colleagueship in this enterprise.
