So all that LabPixies' Line Up playing wasn't a waste of time & brain power? Whew, I is smart now. While I would wait on seeing this study peer-reviewed before believing it wholeheartedly, it's a very interesting study. There are lots of puzzles that purport to improve memory. It's even arguable that Bejeweled can improve visual pattern recognition. What I wonder is, how soon after playing a casual game did the researchers test their subjects? Does this cognitive improvement decrease back to average levels over time? Can it be sustained with frequent gameplay? And does this effect occur in people under 50 years of age?
