Both types of interference impair working memory. (A) Participants were less accurate in trials with as opposed to without interference. Each dot represents the mean reproduction error of one participant. (B) In both distraction and interruption blocks, working-memory performance decreased when interference was present. The interference cost of each interference type was calculated by taking the difference in reproduction errors between trials with and without interference (Interference – No Interference). Individual participants' differences are plotted as dots.
