PsycCRITIQUES - Decades of Pursuing Knowledge for Action Decades of Pursuing Knowledge for Action A review of Child Development and Social Policy: Knowledge for Action by J. Lawrence Aber, Sandra J. Bishop-Josef, Stephanie M. Jones, Kathryn Taaffe McLearn, and Deborah A. Phillips (Eds.) Washington, DC: American Psychological Association, 2007. 311 pp. ISBN 978-1- 59147-425-8. $79.95 Reviewed by Lonnie R. Sherrod This edited volume of 16 chapters plus an introduction and epilogue describes several decades of efforts to use research to improve the life circumstances of children and families. Its subtitle is therefore appropriately “knowledge for action.” Most of the contributors are researchers. All are trained in research. Together they make the important but often neglected point that action should always be based on knowledge and science is one of the most important vehicles we have for gathering knowledge.
