“…Current demands of military operations in Afghanistan and Iraq are generating renewed interest in accelerating rifle marksmanship training. As reviewed by Chung, Delacruz, de Vries, Bewley, and Baker (2006), prior rifle marksmanship research has focused on a range of topics, including evaluating training programs (e.g., Evans, Dyer, & Hagman, 2000;Evans & Osborne, 1998;Evans & Schendel, 1984;Hagman, 1998Hagman, , 2000Hagman, Moore, Eisley, & Viner, 1987;Hagman & Smith, 1999;McGuigan, 1953), examining the relation between performance using a rifle simulator and performance on the firing range (e.g., Hagman, 1998;Marcus & Hughes, 1979;Schendel, Heller, Finley, & Hawley, 1985;Smith & Hagman, 2000Torre, Maxey, & Piper, 1987White, Carson, & Wilbourn, 1991), and the use of shooting as a testbed to study skilled behavior in relation to psychophysiological constructs and measurements (e.g., Bird, 1987;Hatfield, Landers, & Ray, 1987;Janelle et al, 2000;Kerick, 1 We would like to thank the staff at Camp Pendleton WTBN. We also wish to thank the following people from UCLA/CRESST: Joanne Michiuye for her help with the preparation of this manuscript and with data collection, and Daniel Parks for hardware design and development.…”
