We study the hierarchy of reeection principles obtained by restricting the full local reeection schema to the classes of the arithmetical hierarchy. Optimal conservation results w.r.t. the arithmetical complexity for such principles are obtained. Reeection principles, for an arithmetical theory T, are formal schemata expressing the soundness of T, that is, the statement that \every sentence pro...
