The relation between Scrabble © Expertise and Brain Aging as Measured with EEG Brain Signal Variability

Recent empirical work suggests that the dynamics of brain function, as measured by brain signal variability, differs between younger and older adults. We extended this work by examining how the relationship between brain signal variability and age is altered in the context of expertise. We recorded electroencephalography (EEG) from Scrabble experts and controls during a visual word recognition task. To measure variability, we used multiscale entropy (MSE), which emphasizes the way brain signals behave over a range of timescales, and can differentiate the variability of a complex system (the brain) from a purely random system.
