Research on Composites

"Very little is known about the decisions made and procedures implemented by the professionals who routinely interview witnesses and perform facial composite procedures." I found this at the tail end of this great report: Psychology, Crime & Law, October 2006; 12(5): 505517, by McQuiston-Surrett, Topp, and Malpass.  The authors of the report surveyed over 1600 agencies across the US and received a 10% response.  The survey asked them questions about the types of composite systems used and their overall satisfaction with their use.  You should read the report, it is very enlightening.
