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