Abstract: Working memory as one of the most important cognition processes has been always attracting a nice bit of interest in cognitive neuroscience field. Researchers used ERP technique to examine the temporal course and scalp activity area of storage, rehearsal and central executive processing in working memory. A number of ERP studies indicated that the slow cortical potentials are specific to the kind and amount of information retained in the working memory, and the positive difference wave (Pd) is related to the updating function of the central executive. Overall these results validate and reinforce Baddeley’s working memory model.

Key words: working memory, event-related potentials, storage, rehearsal, central executive
