This study that is a good reminder to us who engage in cognitive testing.  What we may find during 1-1 clinical testing may not generalize 100% to real world.  In this study, varying trait stability of working memory during normal school days was found to be significant, with more variability (lack of stability) for some individuals.  I think teachers see this all the time.  This could also suggest that maybe brain-based working memory training programs should be targeted at those children who show the most time-to-time variability in working memory.
