Video game telemetry as a critical tool in the study of complex skill learning.

ABSTRACT: Cognitive science has long shown interest in expertise, in part because prediction and control of expert development would have immense practical value. Most studies in this area investigate expertise by comparing experts with novices. The reliance on contrastive samples in studies of human expertise only yields deep insight into development where differences are important throughout skill acquisition. This reliance may be pernicious where the predictive importance of variables is not constant across levels of expertise. Before the development of sophisticated machine learning tools for data mining larger samples, and indeed, before such samples were available, it was difficult to test the implicit assumption of static variable importance in expertise development. To investigate if this reliance may have imposed critical restrictions on the understanding of complex skill development, we adopted an alternative method, the online acquisition of telemetry data from a common daily activity for many: video gaming. Using measures of cognitive-motor, attentional, and perceptual processing extracted from game data from 3360 Real-Time Strategy players at 7 different levels of expertise, we identified 12 variables relevant to expertise. We show that the static variable importance assumption is false--the predictive importance of these variables shifted as the levels of expertise increased--and, at least in our dataset, that a contrastive approach would have been misleading. The finding that variable importance is not static across levels of expertise suggests that large, diverse datasets of sustained cognitive-motor performance are crucial for an understanding of expertise in real-world contexts. We also identify plausible cognitive markers of expertise.

Project description:BackgroundVideo games have grown in popularity since the 1970s, and tobacco imagery is present in a substantial subset of games, including those oriented to youth. Much like exposure to tobacco content in films, exposure to tobacco content in video games may influence smoking uptake and use; however, the tobacco industry's role in facilitating or promoting the use of tobacco imagery in video games is unclear. We explored the industry's interest in and use of video games to market their products to youth and young adults.MethodsWe retrieved and analyzed archival tobacco industry documents. We supplemented information from the documents with current and archived versions of several brand and corporate websites and one website containing user-supplied information on video games.ResultsTobacco companies recognized the youth appeal and marketing potential of video games as early as 1980. Initial marketing ideas included incorporating video game themes into product packaging and design. More fully realized plans focused on incorporating video games into product promotions in bars, as a high visibility way to attract younger patrons and increase long-term marketing opportunities by generating names for tobacco company direct-marketing databases. Tobacco companies also incorporated video games into in-home product promotions, primarily as components of brand websites, in order to enhance brand image and generate repeat website traffic. A similar desire to attract and keep visitors led to discussions about the inclusion of video games on corporate youth smoking prevention websites, although only one company, Lorillard, followed through.ConclusionsVideo game players are an attractive target market for tobacco companies. Video games, as used by these companies, facilitate consumer engagement with particular tobacco brands or particular corporate messages. Eliminating the use of video games as a promotional vehicle may require limiting tobacco marketing in both physical and online environments.

Project description:Motor learning occurs over long periods of practice during which motor acuity, the ability to execute actions more accurately, precisely, and in less time, improves. Laboratory-based studies of motor learning are typically limited to a small number of participants and a time frame of minutes to several hours per participant. There is a need to assess the generalizability of theories and findings from lab-based motor learning studies on larger samples and time scales. In addition, laboratory-based studies of motor learning use relatively simple motor tasks which participants are unlikely to be intrinsically motivated to learn, limiting the interpretation of their findings in more ecologically valid settings ("in the wild"). We studied the acquisition and longitudinal refinement of a complex sensorimotor skill embodied in a first-person shooter video game scenario, with a large sample size (N = 7174, 682,564 repeats of the 60 s game) over a period of months. Participants voluntarily practiced the gaming scenario for up to several hours per day up to 100 days. We found improvement in performance accuracy (quantified as hit rate) was modest over time but motor acuity (quantified as hits per second) improved considerably, with 40-60% retention from 1 day to the next. We observed steady improvements in motor acuity across multiple days of video game practice, unlike most motor learning tasks studied in the lab that hit a performance ceiling rather quickly. Learning rate was a non-linear function of baseline performance level, amount of daily practice, and to a lesser extent, number of days between practice sessions. In addition, we found that the benefit of additional practice on any given day was non-monotonic; the greatest improvements in motor acuity were evident with about an hour of practice and 90% of the learning benefit was achieved by practicing 30 min per day. Taken together, these results provide a proof-of-concept in studying motor skill acquisition outside the confines of the traditional laboratory, in the presence of unmeasured confounds, and provide new insights into how a complex motor skill is acquired in an ecologically valid setting and refined across much longer time scales than typically explored.
