This　study　focused　on　two　different　views　about　the　role　of　category　label　in　inductive　reasoning:　perceptional-similarity-based　and　conception-based　views.　We　used　an　inductive　reasoning　task,　possibility　judgment　for　a　feature　of　artificial　insect,　to　record　behavioral　performance　in　experiment　1　and　brain　activity　with　ERP　in　experiment　2.　Two　factors　were　manipulated:　visual　similarity　of　artificial　insect,　and　whether　with　same　label　or　not.　The　result　suggests　that　the　conception-based　view　is　not　supported　here.　The　category　label　may　enhance　the　perceptual　characteristics,　since　labels　have　same　visual　and　sound　features;　but　it　is　hard　to　deny　the　role　of　conceptual　information　contained　by　a　label　to　affect　the　inductive　reasoning.　©　2012　Springer-Verlag.
