WM components Behavioural variables Central executive Manipulation Digit forward vs backward spans     Corsi forward vs backward spans     Alphabetical vs serial recalls from  the alpha span task   Inhibition Interference vs naming times= interference score from the Stroop test   Flexibility Flexibility vs interference times= flexibility score from the Stroop test Phonological loop Articulatory rehearsal component Long vs short words spans= word-length effect   Phonological store Similar vs dissimilar letters spans = phonological similarity effect Visual sketchpad Visual component Matrices spans   Dynamic component Forward Corsi block-tapping spans Table 1 summarizes the links between the behavioural variables considered here and the different WM components of Baddeley's model.
