The effect of shape on the memory encoding of color schemes was examined using human-body shapes andrectangles, and N2 posterior contralateral (N2pc) and contralateral delay activity (CDA) were obtained from theevent-related potential during memory encoding. The task involved memorizing a stimulus presented in the left andright visual fields. The N2pc amplitude was largest when rectangular color schemes were memorized and the humanbodyshapes were distractors. No significant difference was found in the CDA amplitude between the shapes. Theseresults suggested that the memory of the color schemes was affected by selective attention rather than sustainedattention.
