Because it has been a few years since Jeromy's original answer, and because I just read a very apt article, I will venture an update on the state of the field with respect to the BPI's validity. Overall, despite more research into brain training and Lumosity, there is little to no peer-reviewed evidence supporting the Lumosity BPI's validity, nor evidence ...

Because of the way you've set up the stimulus presentation here, these are effectively all serial verbal working memory tests where the neurocognitive basis may differ or not depending on a number of unstated factors such as stimulus modality or type (e.g., Polyn et al., 2005), ...

'Precision' in classical test theory Most accounts of classical test theory do not have a notion of precision as such, but occasionally, reliability may be called precision instead. The relationship is probably most concisely illustrated with the standard dartboards. This is also explained on the Wikipedia Item Response Theory page, but as you can see, in ...

And you're probably right; time constraints will most likely place subjects into system1 thinking. Subjects' having knowledge about an experiment may generally ruin it, for it can make testability collapse (how ...
