“…Although there are measures of playfulness (i.e., the propensity of an individual to engage in play; Webster & Martocchio, 1992), and observational ratings scales for child play exist throughout the developmental literature (e.g., Knox, 1997), a self-report scale of play behavior is markedly absent. This gap is even more surprising given the recent surge in investigations into the science of games (e.g., Chertoff, Jerome, Martin, & Knerr, 2008;Cotton, Mayes, Jentsch, & Sims, 2001;Pavlas, Heyne, Bedwell, Lazzara, & Salas, 2010). Although the human factors community has embraced games for training (e.g., Gopher, Weil, & Bareket, 1994;Lampton, Bliss, Orvis, Kring, & Glenn, 2009) and examined the basic science of games, the field has not more closely examined the psychological correlates of game play.…”
