title: The effect of late posterior negativity in retrieving the color of Chinese characters.
abstract: Previous event-related potentials (ERPs) research has suggested that the retrieval tasks for many sources of items were operated in the frontal regions, but Cycowicz et al. [2-4,6] recorded the late posterior negativity (LPN), a component over the posterior cortex, in retrieving the associative color sources of pictures. To examine whether the LPN could also be observed in retrieving both the associative and the organizational color sources of verbal stimuli, two experiments were designed by using Chinese nouns as stimuli. Both experiments revealed significant LPN that was related to the tasks of color source retrieval. These findings demonstrate that the association between LPN and search for and/or retrieval/evaluation of the colors of objects is fairly strong, and this association is insensitive to both the attributes of stimulus materials and those of the color sources.
