When Gaming Is Good for You - WSJ.com - 3 views

    This type of research is very difficult to do - so without examining the actual research articles it is difficult to determine how valid these studies are

    The WSJ article makes strong causal claims based on observational studies. Classic confounding of correlation and causation. From what I could find of the Michigan-based research, for example, the "effect" of video game playing on behavior was a fixed-effect in a multiple regression analysis. It didn't (or shouldn't have) carried any causal implication. (Interestingly, the research also found that students with higher self-reported video game playing times over the school year also had lower GPAs...a finding conspicuously missing from the WSJ piece.)
