The University of South Carolina is a public, co-educational research university located in Columbia, South Carolina, United States, with seven satellite campuses. Its campus covers over 359 acres in downtown Columbia not far from the South Carolina State House. The University is categorized by the Carnegie Foundation for the Advancement of Teaching as having "very high research activity" and curricular community engagement. It has been ranked as an "up-and-coming" university by U.S. News & World Report, and its undergraduate and graduate International Business programs have ranked among the top three programs in the nation for over a decade. It also houses the largest collection of Robert Burns and Scottish literature materials outside of Scotland, and the largest Ernest Hemingway collection in the world.Founded in 1801 as South Carolina College, South Carolina is the flagship institution of the University of South Carolina System and offers more than 350 programs of study leading to bachelor's, master's, and doctoral degrees from fourteen degree-granting colleges and schools. The University of South Carolina System has an enrollment of approximately 47,724 students, with 32,848 on the main Columbia campus as of fall 2013. USC also has several thousand future students in feeder programs at surrounding technical colleges. Professional schools on the Columbia campus include social work, business, engineering, law, medicine, and pharmacy. Wikipedia.

It has been widely shown that recognition memory includes two distinct retrieval processes: familiarity and recollection. Many studies have shown that recognition memory can be facilitated when there is a perceptual match between the studied and the tested items. Most event-related potential studies have explored the perceptual match effect on familiarity on the basis of the hypothesis that the specific event-related potential component associated with familiarity is the FN400 (300-500ms mid-frontal effect). However, it is currently unclear whether the FN400 indexes familiarity or conceptual implicit memory. In addition, on the basis of the findings of a previous study, the so-called perceptual manipulations in previous studies may also involve some conceptual alterations. Therefore, we sought to determine the influence of perceptual manipulation by color changes on recognition memory when the perceptual or the conceptual processes were emphasized. Specifically, different instructions (perceptually or conceptually oriented) were provided to the participants. The results showed that color changes may significantly affect overall recognition memory behaviorally and that congruent items were recognized with a higher accuracy rate than incongruent items in both tasks, but no corresponding neural changes were found. Despite the evident familiarity shown in the two tasks (the behavioral performance of recognition memory was much higher than at the chance level), the FN400 effect was found in conceptually oriented tasks, but not perceptually oriented tasks. It is thus highly interesting that the FN400 effect was not induced, although color manipulation of recognition memory was behaviorally shown, as seen in previous studies. Our findings of the FN400 effect for the conceptual but not perceptual condition support the explanation that the FN400 effect indexes conceptual implicit memory.
