EFFECTS OF THE HUMAN-BODY SHAPE ON THE MEMORY ENCODING OF COLOR SCHEMES −A STUDY USING THE DIFFERENCE WAVE OF THE EVENT-RELATED POTENTIAL BETWEEN CEREBRAL HEMISPHERES−

Abstract

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.
