If separate: performance is worse when pointing vs speaking bc both will be visual. Visual interferes more with visual than with verbal & vice versa: separate stores. Primary task: reproduction of chessboard positions is visual. Secondary: interferes with 1 of 3 components of working memory. If separate stores will have no efect bc not visual memory. Tap a series of keys in a predetermined pattern: prevent visual spatial sketchpad & interfere with location of chess pieces bc also visual. Produce stream of random letters: interfere with the central executive bc coming up with strategy for choosing random letters. Should interfere with position recall bc both tasks tap into central executive.
