We aimed to compare the effects of the Dynamic Visual Noise (DVN) on visual memory when presented at different times in an item recognition task either during information encoding, retention interval or throughout the trial. Noise had general effect on participants' performance with stronger impairment on stimuli encoding. The data suggest that visual memory is accessed through perception and, therefore, it suffers external interference, as the one caused by the DVN. We consider that the effect occurred while the information was being kept in consciousness by a specific short-term storage subsystem. These results contribute to the understanding of the architecture used by the visual working memory and show that the DVN is an appropriate technique to study the visual memory.
