Categorization　concept　could　be　divided　into　three　levels　according　to　the　degree　of　generalization:　superordinate,　basic　and　the　subordinate　levels.　To　investigate　the　neural　mechanism　of　concept　information　retrieval　from　the　different　levels,　animals　and　vehicles　were　chosen　as　materials　and　a　picture-word　matching　task　was　used　in　this　study　with　the　technique　of　ERP.　The　behavioral　results　showed　basic　concepts　were　retrieved　most　quickly　and　much　faster　than　retrieving　those　concepts　in　superordinate　and　subordinate　levels.　The　ERP　results　showed　that　there　was　an　enhanced　ERP　signals　in　the　early　stage　for　the　condition　of　superordinate　level,　including　the　time　windows　of　N1　and　300-500　ms,　suggesting　a　superordinate　level　advantage;　but　in　the　late　stage　(time　window　500-600　ms),　a　basic-level　advantage　was　observed.　These　results　indicated　the　retrieving　advantage　of　concept　level　appeared　from　superordinate　back　to　basic.　©　2012　Springer-Verlag.
