Abstract: Video game naïve participants were trained on a first-person shooter
action video game (AVG) for 30 hours or received no training, then were tested on three
visuospatial tasks while electroencephalography was recorded. Accuracy was significantly
better in AVG-trained than non-trained participants for naming objects rotated in-depth and
enumerating 2-4 targets (i.e., subitizing). Major ... read moregroup differences were evident at
anterior sites during an N3 complex (~300-500 ms) indexing the process of matching
perceived information to stored structural knowledge (i.e., object model selection).
Compared to non-trained participants, electrophysiological analyses indicated that
AVG-trained participants utilized object-specific and rotation imagery processes
efficiently during mental rotation (Experiment 1), view-dependent model verification
processes more consistently enhancing object constancy (Experiments 2a and 2b), and early
beneficial pattern matching processes facilitating subitization (Experiment 3). Overall,
goal-specific percept-to-memory matching was better in the AVG-trained group likely
contributing to their superior accuracy.
