Table 3 Forward stepwise multiple linear regression between Xbox® games, (dependent variable) and visual attention and other variables. The variables that were entered into each model are shown beneath. The model for Stomp-It was run first with the full range of variables (full model), and secondly excluding the non-modifiable factors of age and gender
