Data were collected in both research locations using identical protocols that were approved by their respective University Institutional Review Board. Research assistants from both locations were trained together by the project’s Principal Investigator on protocol administration and psychophysiological editing. To ensure that identical protocol administration was maintained between the labs, the Blacksburg site periodically viewed DVD recordings and psychophysiology files collected by the Greensboro site. To ensure that identical coding criteria were maintained between labs, the Blacksburg site provided reliability coding for all data collected by the Greensboro site.
